This sounded great. I uploaded it, and all my widgets disappeared (in Firefox). Still interested in seeing it work. Any suggestions?

Thanks… Lee

Hi Lee,

Disappeared? That is sound very serious. I use it myself, it works fine.

So will you please check the cache folder under the WP Widget Cache pluglin folder, is there such a folder, and is there any files under it?

Sorry for this.

Sep 8th, 2008
Andrew

Oh, Lee, your site is running on PHP 4 or PHP 5 ?

Thank you very much. I always worried about using more than a few plugins for site slowdown reasons.

Hi Baron and Gbeans,

I’m very glad to see you like this plugin.

Thanks.

I will try to use this plugin….

Sep 9th, 2008
Andrew

Thanks for your trying, Sapimoto.

If having any issues, just tell me here.

Great plugin! but I go to themes -> widgets , see the “clear all widgets cache” button and “(” only.

Sep 10th, 2008
Matt

The plugin sounds like a great idea, very logical. Not point reading the same info from the database again and again. Thanks for it, I will be sure to use it soon.
Cheers

Trying to stick to a minimalist/speedy design has always been my goal, and this plugin makes it all the easier! Thanks a lot buddy!

Sep 10th, 2008
Andrew

Hi Leo,

The source code of the button will be

<input type=”submit” name=”widget_cache-clear” id=”widget_cache-options-submit” value=”Clear all widgets cache” /> (<num>)

If you only see a “(”, I think it may be some style problem, please right click and see your page source, if the code are all right, then you can try some debuging.

For Firefox, you can use Firebug, https://addons.mozilla.org/firefox/addon/1843,

For IE, you can use IE Developer Toolbar, http://www.microsoft.com/downloadS/details.aspx?familyid=E59C3964-672D-4511-BB3E-2D5E1DB91038&displaylang=en

These plugins will tell exactly the occupied areas of the button.

Any issues, just leave a comment here.

Thanks Andrew,
I don’t know how to fix. I am using the wordpress 2.6.2 default admin interface and I’ll try to fix.

Jonathan Wong

Andrew, love the plugin, and thanks for your great work.

Question: Do you know if there is any significant performance difference for caching widgets that are HTML-based? For example, I have a HTML widget that displays a 100% static Creative Commons license at the bottom, a mostly static HTML widget for ‘About Me’ (with only one line of PHP code to display my Dopplr status), and a search widget which I think is static.

Should I bother to cache those?

Sep 12th, 2008
Andrew

Hi Jonathan,

Thanks for trying this plugin.

There’s no need to cache static content, as cache itself is something static too.

Sep 12th, 2008
Andrew

Oh Jonathan,

I just visit your site, and I thought I should explain more clear.

As far as I konw, the Search Form is the only widget that use a static file, it’s file ’searchform.php’ under your theme folder. The text widget, on the other side, will query the database to get the text content, so it’s not static, and should be cached.

Any way, there’s no harm to cache a widget.

Sep 12th, 2008
Jonathan Wong

Ahh… OK. That makes sense. Thanks.

I use widget cache today,work perfect.Anyway i have little problem.My site use 3 column.So it have 2 siderbar.I try to use “auto expire these things changed” but it didn’t actually saved.More clearly like this
On sider bar 1,after config,i save change,ok it saved,anyway when i go on sider bar 2 then config and saved.Tick box “auto expire these things changed” on sider bar 1 haven’t save anymore ?
Sorry my bad english hope you can understand it ^.^!

Andrew

Hi Lordgoth,

Yep, it’s a bug, I’ll release a new version later.

Thanks for helping me improve this plugin:)

Sep 13th, 2008
Andrew

Hi Lordgoth,

I just released a new version 0.15.1, it should fix the bug.

Thanks again:)

Hi Andrew,

I was the one who informed you about the issue with the MiniMeta Widget. Here’s what I just had to do to get your plugin to work with MiniMeta (so far).

I went into the MiniMeta Widget. I took a print screen image of the settings. I could have written them down of course. Then I activated your plugin, set all the cache times, and saved. After the save, the MiniMeta Widget was empty again even though the cache time was left empty. I reset the MiniMeta settings and resaved. So far, it’s holding.

One might want to deactivate MiniMeta before activating your plugin and then reactivate MiniMeta after setting all the cache times. That might work.

Well, I thought I’d just give you an update. There is something in your plugin that is clearing the MiniMeta settings when the Widgets page is updated via the Save Changes button. It shouldn’t do that.

Blessings to all,

Tom Usher

Sep 13th, 2008
Andrew

Hi Tom,

Sorry for this issue.

Actually I mentioned a werid thing in my last email to you. Please deactive WP Widget Cache first, that’ll make things clear. Then move the position of MiniMeta, up or down, then save. I found the settings are clear too. So is it possible there’s some bug with MiniMeta?

Ok, please confirm this first, if without WP Widget Cache, MiniMeta works all fine, I’ll have a more careful look at the source code of both side.

Thanks for helping me improve this plugin:)

Andrew

Brian Brigg

I love your widget and was using it but I have run into a problem with the upgrade process. I cannot use the automatic upgrade as it will not get rid of the old version so I tried to delete the old version using FTP but still no luck. Logged into cPanel and tried deleting using the file manager from there and still could not get rid of it.

Any suggestions? I would like to upgrade and keep using the plugin.

Sep 13th, 2008
Andrew

Hi Brian,

Thanks for trying this plugin.

Do you have problem with deleting the plug-in folder, likely to be ‘wp-widget-cache’? If so, you can try to update some files under the plugin folder, just two .php files, widget-cache.php, and inc/wcache.class.php. For the files under cache folder, please delete them all.

Or you can try to rename the old plug-in folder, then reinstall.

Let me know whether it’s helpful.

Regards,
Andrew

Hey Andrew, I needed some clarification.

I use WP-Super Cache (without the GZip) on my site in conjunction with WP-Widget Cache. Suppose that my super-cache expiration time is 3,000 seconds while my Statistics widget (controlled by Widget Cache) has an expiration of 2,000 seconds.

If my main page has been super-cached and all the widgets have been cached at some time, let’s say time 0, and my statistics widget is set to expire in 2,000 seconds, will I have to wait for the super-cache page to expire in order to reflect changes in the statistics widget, or will the widget refresh EVEN THOUGH the entire page is still super cached?

The reason I ask is because I love the Super Cache plugin serving static pages instead of having to requery the database everytime, but I would still like my widgets to refresh. Donncha (Super-Cache’s creator) has said that in order to do this, the widgets would have to be rewritten as Javascript (in other words, javascript widgets remain dynamic, even on super-cached pages).

Sep 17th, 2008
Andrew

Hi Rishi,

WP-Super Cache will cache an entire page to a static file, and WP Widget Cache will cache the output of Widget. If entire page is cached, then it will fetch the static page and return, no longer reach the widget output, so page cached is more high-priority, it stands in front of WP Widget Cache.

Donncha is right, for page cache, javascript(maybe ajax) is the solution for leaving some part dynampic. Or we should use part cache(like only cache the post part, comment part, siderbar part), not entire page cache.

I think I’ll think this requirement for the next version.

Regards,
Andrew

Rishi

Thanks for the quick response, buddy! That’s what I figured. Nevertheless, your plugin has a nice home in my corner of the Internet. :-)

I get the following message where my widgets used to be:

Warning: Illegal offset type in /export/home/he/herita51/public_html/Wordpress/wp-content/plugins/wp-widget-cache/widget-cache.php on line 446

Any suggestions?
Thanks

Sep 24th, 2008
Conrad Erway

It turns out the above occurred when i did not have any time inserted in the widgets. When I put in 3600 seconds all of my widgets disappeared.

Sep 24th, 2008
Andrew

Hi Conrad,

Please make sure your wordpress version is 2.5 or later. If so, I am not very sure how could this happen, but I think you can help debug this.

/wp-content/plugins/wp-widget-cache/widget-cache.php, I need you to replace this file with this one, http://www.mashget.com/widget-cache.zip

Then please try again to see if it’s OK for display.

I think you may miss some widgets, then you can look at the page source to find this:

<!–WGC Error

Please tell me what you got.

Sep 24th, 2008
Conrad Erway

Andrew,

My Widgets still do not appear. I am running Wordpress 2.6.2. I do not see the WGC Error message any where in the source code. I am using only two widgest at this time, Text and Events Calendar. I am also using SuperCache.

Sep 24th, 2008
Andrew

Hi Conrad,

Once there’s a warning msg, when you left the time field empty, right?

Warning: Illegal offset type in /export/home/he/herita51/public_html/Wordpress/wp-content/plugins/wp-widget-cache/widget-cache.php on line 446

Please debug in this situation.

Sorry for this trouble.

Andrew

Sep 24th, 2008
Conrad Erway

Andrew,

I did as suggested: I uploaded the new widget-cache.php file and removed the time from the widget time fields. The results was the following message:

Warning: Illegal offset type in /export/home/he/herita51/public_html/Wordpress/wp-content/plugins/wp-widget-cache/widget-cache.php on line 452

Sep 25th, 2008

HI Conrad,

I really confused about this issue:(

I just googled the waring msg, and I got this: http://weblog.kreny.com/archives/2004/12/troubleshooting.html, basically it said maybe the Zend Optimizer version was too old, but as the entry was in 2004, very old too, likely not helpful.

Truly sorry for this.

This is just awesome! Great plugin.

Thanks for making it available!

Sep 26th, 2008
Conrad Erway

Andrew,

That may be the problem, In my case, I find that I am running PHP 4.4.4 with Zend engine v1.3.0 . My site gives me the following info re the Zend engine:
This program makes use of the Zend Scripting Language Engine:
Zend Engine v1.3.0, Copyright (c) 1998-2004 Zend Technologies with eAccelerator v0.9.5, Copyright (c) 2004-2006 eAccelerator, by eAccelerator with Zend Extension Manager v1.0.9, Copyright (c) 2003-2005, by Zend Technologies with Zend Optimizer v2.6.0, Copyright (c) 1998-2005, by Zend Technologies

Hi Jan,

Vary glad you like this plugin:)

Sep 26th, 2008

Hi Conrad,

Zend Optimizer v2.6.0 is not that old, as the entry mentioned, 2.5.7 would solved the waring msg. Still no idea:(

Satranç

Hi,
Nice work. Are you planning a wp-mu version of this plugin?

I mean a centralized control for widgets by wpmu admin. I need sitewide cache properties for widgets.

Oct 18th, 2008
Satranç

Or simplest way: is there a way to install this widget by sitewide defaults.

Oct 18th, 2008
Andrew

Hi Satranc,

I should admit that I’m not very familiar with mu yet, but I do plan to.

Oct 18th, 2008
Danny

Thanks for an excellent plugin, Andrew.

One to add to your list of widgets that should not be cached:
Calendar widget (that comes with WP)

If you ever figure a solution for that one, please let me know as it has an overhead of 3 DB queries.

Looking forward to your next GREAT CREATION !!

Thanks,
Dan

Nov 1st, 2008
Andrew

Hi Danny,

Thanks for trying this plugin:)

About Calendar widget, I do missing something, as if cached, when Nov.1th camed, it might still be Oct.31th, it’s this reason, right?

Sly

Hi
After i used this plugin, my RSS feeds are not updating. Same in dashboard. The RSS feed from wordpress display same articles for 3 days, and nothing changes.
Why?

Nov 5th, 2008
Andrew

Hi Sly,

This plugin will just cache the widget for a period of time, I don’t get how could it affect the dashboard rss. But I think you can try to de-active this plugin, and then check whether the feed was updating.

Nov 5th, 2008
Sly

Sure. It’s deactivated.
And nothing hapend.
The dashboard news remain unchaged, and some of RSS feeds from website are still unchanged.

Nov 6th, 2008
Andrew

Hi Sly,

If this plugin is deactived, then it’ll not affect the wp anymore, so if the rss remain unchanged, it must be something else.

Nov 6th, 2008

upgraded the plugin today, and now it gives these errors:

Warning: mkdir() expects at most 2 parameters, 3 given in /home/quick42/public_html/biblemoneymatters/wp-content/plugins/wp-widget-cache/inc/wcache.class.php on line 84

Steve Mermelstein

I’m having the same issue as Peter and Christian and had to revert to the previous version.

Nov 24th, 2008
Andrew

Hi Steve, Christian, Peter,

I’m so sorry for this. The reason is you’re using php 4, and the function mkdir accept the 3rd param since php 5, I should have thought of this.

I’ve just release a new version 0.25.1, please update.

Regards,
Andrew

Nov 24th, 2008

Thank you for fixing this so quick Andrew!

Nov 24th, 2008
Pete

I mentioned above that my problem was fixed, and the original problem WAS fixed.

Today I wrote a post and hit the save button from this page: http://www.yourwebsite.com/wp-admin/post.php?action=edit&post=1613

Instead of saving as it normally does, today it refreshed to a blank Page:

http://www.yourwebsite.com/wp-admin/post.php

The same thing happens when i try to publish the post – it just goes to the blank page:

http://www.yourwebsite.com/wp-admin/post.php

I deactivated the widget cache plugin, and the save/publish features work again.

Can you look into that and see why the plugin might be causing this problem?

Nov 25th, 2008
Andrew

Hi Peter,

I’ve no idea about how could cause such a problem, is there any ‘error_log’ in your web root folder or the wp widget cache plugin folder, that might help me figure out why.

Regards,
Andrew

Jeremy Day

Hi.

Wanted to let you know I encountered the same exact issue as Pete and reached the same resolution by deactivating the new upgraded plugin. Not sure how I can help resolve the issue.

Jeremy

Nov 25th, 2008
Andrew

Hi Jeremy,

Is there any error_log in your wp-admin folder?

Also, please tell me, whether you use the ‘auto expire options’, and check ‘posts’, I think it might have something with this.

Regards,

Nov 25th, 2008
Steve Mermelstein

Hi Andrew,

I don’t have an error_log but I too I’m having the same issue as Pete and Jeremy. I resolved it by deactivating the plugin.

I did have the expire option set to 3600 and had posts checked in several widgets that needed to be updated when posts are. I also had tags checked in my tag cloud and categories checked in my category cloud widget. When saving a post it had a lot of problems with the categories, checking off categories that weren’t checked and not saving all the tags that were added to the post. I hope this information helps.

Nov 25th, 2008
Pete

no error log in there.. i had the expire options set to either 0 or high numbers, higher than 3600. i didn’t check to auto expire.

Nov 26th, 2008
Andrew

Hi Pete, Steve,

I can’t find the reason, I’ve left the msg on http://wordpress.org/support/topic/220033, hope someone might help us.

Nov 26th, 2008
Friedel

I have exactly the same problem as Pete!
And when i write a page or a post, every time WP saves automatically, it produces a new post or page, that can’t be deleted if the plugin activated…?
Turn off the plugin -> things work fine.

Nov 29th, 2008
Andrew

Hi Friedel,

There’s been 4 users telling me that having the same problem as you, but I can’t replicate this error or find the reason. I’ve left the message on http://wordpress.org/support/topic/221283 , hoping someone might help us.

Before this issue solved, I think you can use an older version, http://downloads.wordpress.org/plugin/wp-widget-cache.0.22.1.zip, if you think the update notice is boring, please edit the ‘widget-cache.php’, changing the 7th line to ‘Version: 0.25.1.1?.

Regards,
Andrew

Nov 29th, 2008
Peter

I’ve gone back to using the old version until /if when the new one gets an update. Thanks for your hard work – love the plugin – just want it to work correctly with my blog for the new version! thanks!

thomas

hi and thx for this plugin!!
I have one little question. step 3 of the installation “make sure the subfolder ‘cache’ is writable”. Which subfolder??? Do i have to create one? In the /plugins/wp-widget-cache directory??

I just asked because after installation no cache subfolder was created … and so i think the plugin don´t work right now :(

greetings,
thomas

Dec 2nd, 2008
Andrew

Hi Thomas,

The installation was for the version before 0.25(I’ll update this later), the cache folder is now move to /wp-content/widget-cache.

Also if you want to know the widget cache works or not, you can have a look at the source of the page, and search ‘<!–WP Widget Cache End –>’. If no such string, the widget cache might not work properly.

Any problems, just tell me. Thanks.

Regards,
Andrew

Dec 2nd, 2008
tigtog

@ Andrew, I had a similar problem as the other people with not being able to write/edit pages, but writing posts was working just fine. Deactivating widget cache fixed the problem. I left a message on the support forum topic you link to above as well.

Dec 19th, 2008

Hi Andrew,
thanks for your reply, i still had the 0.22.1 on my HDD, so there was no problem to get it back to work… :)
Thanks for the Tip with the 7th line!

Aouni

Hello Andrew. I liked this plugin very much, although I would liked it to work with Widget Logic. I have some widgets which appear on my blog homepage only, but when I install Wp Widget Cache, the widgets appear everywhere.

Is there a way to solve this and make it work with Widget Logic?
Thank you.

Dec 21st, 2008
Andrew

Hi Aouni,

Widget cache can’t work with widget logic for one widget at the same time.

For the moment, you should leave the expire time field empty for that widget, so the widget cache will not cache that widget.

Regards,
Andrew

Dec 21st, 2008
Aouni

Hey, thank you Andrew, I did what you’ve said and I got to decrease my queries by 5. Better than nothing ;]

Sorry, am not an advanced developer, should I consider these 5 queries a big deal?

P.S. I got decrease down sql queries in my blog from 72 to 37 at first with PHP Speady plugin, and not it has become 32 with widget cache.

Thanks a lot.

Dec 22nd, 2008
Rex Reed

This plugin doesn’t seem to work at all for me. I have a scary 104 queries per page on my site, and I’m sure it’s because of the plugins. I just upgraded to Wordpress 2.7 and installed WP Widget Cache 0.25.1. After activating the plugin, I don’t see any changes at all in the site. Also, I don’t see where I can configure Widget Cache to act on the widgets.

On the Appearance -> Widgets Screen, when I scroll down, I see this button, but the HTML is all weird:

WP Widget Cache Options

When I look at the widget-cache directory, I see a few files, but they are all 41 bytes long and just have this info in it:

a:2:{i:0;a:0:{}s:10:”__output__”;s:0:”";}

So, this is not having any impact for me…. help!

Dec 23rd, 2008
Andrew

Hi Rex,

Please have a look at the http://wordpress.org/extend/plugins/wp-widget-cache/screenshots/ , and if you can’t see the ‘expire in’ field, please check the settings->wp widget cache to make sure this plugin is turned on.

Regards,
Andrew

Dec 23rd, 2008
Rex Reed

Thanks — that worked, but you might want to update your screenshots, since they are not valid in Wordpress 2.7.

Also, how do I force a part of my page to cache that’s not formally a widget? I have a portion of my theme that seems to make a lot of calls to the database that should be cached…. how can I use Widget cache to cache that part of the page? (I.e. treat it as if it was a widget?)

Happy holidays!

Dec 24th, 2008
Rex Reed

Another question: I am having the same problem that others mentioned where I have 2 sidebars, but the expiration information for widgets in Sidebar #2 is not saving… was this fixed?

Dec 24th, 2008
Andrew

Hi Rex,

If you want to cache some part of your page that is not a widget, you should write some code yourself, first you should figure out the part on the page, then find the code that generate this part, then cache the code. Widget cache use the cache class from Dragan Bosnjak(http://www.phpclasses.org/browse/package/3807.html), it’s very easy to use.

The problem about cache mutiple sidebars have a fix since 0.15.1, if you still got this problem, will you please provide more details, the expiration cleared?

Regards,
Andrew

Hi,
I can’t delete comments,
Move page as sub page at Wp 2.7 & Wp-Widget-Cache 0.25.1 .

I think this is a javasscript problem.

Jan 19th, 2009
Andrew

Hi Satranç,

Try clear the widget cache in the settings page first. WP widget cache didn’t use any javascript.

Andy

Hi there

I’ve got no idea what the optimum cache time in seconds might be for various widgets, can you please advise in general terms? For example a Twitter widget needs updating constantly – an archives widget less so, but what seconds for each? Many thanks!

zonebattler

Hi Andrew,

thank you very much for providing such a great plugin: Since I use 17 widgets in my blog (WP 2.7), it speeds up response time most notably! There is, however, a strange problem. As somebody else reported before, I also don’t see the button for clearing the cache content (Win XP, Opera 9.63), but I get portions of trunctated code instead:

<input type=”submit” name=”widget_cache-clear” id=”widget_cache-options-submit” value=”Clear all widgets cache(

Please see my screenshots of the plugin’s options page at

http://www.klein-aber-fein.de/downloads/wp-widget-cache-1.jpg

and the blog’s widget page at

http://www.klein-aber-fein.de/downloads/wp-widget-cache-2.jpg

While this would be only an aesthetical problem (’though a nasty one), there is a second problem which may be related to the first one: every time I edit a post or a comment and hit the submit button, the screen turns white and the wp-admin/post.php or wp-admin/comment.php won’t show up again. Deactivating your plugin solves the issue immediately, however I really, really, really wouldn’t want to get rid of your useful plugin! Do you see any chances of helping me (and the other guys encountering the same issue)?

Thanks for your time and greetings from Germany,
Ralph

I would like to add some observations to zonebattler’s comment. In Firefox 2.0.0.20 the button is displayed properly but a look at the code generated by the WP Widget Cache plugin reveals that the page is truncated after “Clear all widgets cache(”. The page is clipped with Opera 9.63 and Internet Explorer 6.0 as well; these browsers don’t display the button properly. Iron (based on Google Chrome) truncates the page right after “” so no parts of the button are visible.

Oops, not escaped properly – it should read ‘truncates the page right after “<span class=”submit”>’.

Widget-Cache and admin issue:

there is a trouble with 2.6.3 admin with widget-cache enabled – when we adding widget to sidebar and making post to save settings widget_control function does not called and widhet placement is skipped. Tested with php-code-widget.

I found this happens cause when wordpress receiving post request it forwards user by 302 page to avoid double posting. During first request no additional widget controls evoking except basic widgets described in widgets.php such as tag_cloud, pages, recent-comments and so on. since so post request, targeted to controls of other widget is missing in action.

In my WP 2.7.1 installation (with PHP 4), the admin widgets seem to be cached. For example, I have 2 categories – uncategorized and mycategories. Both actually have about 50 posts, but in the admin panel, the category widget shows 50 for mycategories and 0 for uncategorized.

PS: I’m also using WP Super Cache.

* Sigh * Forget what I posted earlier.

1. When I used Quick Edit on my Posts (to change the Categories), the updates failed.
2. When I turned off Widget Cache, the updates succeeded.
3. However, the Category widget (in the admin panel) still showed the wrong number of posts.
4. When I turned off Super Cache, the Category widget (in the admin panel) still showed the wrong number of posts.

Conclusions:
1. I can’t use Widget Cache because it clashes with my Post Quick Edit function.
2. Widget Cache is not responsible for Category (in Admin) showing the wrong post count.

I am having the same problem. Whenever wp-cache is installed AND I have a widget set to update whenever a post is made, I cannot edit or delete pages. I just get taken to a blank page. Taking the “update widget on post” option out makes everything work, but that’s not ideal as it’s a “recent posts” widget.

I am not sure if I am suppose to reset the expiation date of each widget or if there is a default setting. Each widget box now as an option at the top. Am I supposed to change that or leave it blank? Every things seems to be working okay but I am not 100% sure.

Can I run WP Hyper Cache at the same time as WP Cache? Or should I only run one of them? I am trying to reduce strain on my hosting server but may one day switch to a new service, but if I can reduce load via caching I will stay longer.

So, what am I do to in each of my widget boxes? Nothing? Or change each one (except dynamic widgets?) to what? What is a standard amount of time?

I decided to deactivate Hyper cache and use only WP Cache with Widget Cache. Will leave all widget boxes to zero and assume it will auto clean or expire when a change is made to the widget. Any advise is appreciated but I think it is working.No noticable problems yet. Nothing dissappeared.

Hello,

Is it possible to get the same information as provided by WP Widget Cache — but in the form of a RSS feed? If so, how exactly? (Thank you for Widget Cache — I do find it useful in sites I visit; but it would be more useful for me if these sites provided the same information as a RSS feed.)

Thanks,

I got an AdSense widget on my sidebar which shows a list of ads by Google. I don’t think this great plugin will negatively affect the AdSense function, will it?

Many of my widgets are called directly from a template tag in the sidebars. Is there any way I can cache these widgets using widget cache, as they don’t appear in the widgets admin side. (This was Also posted on WP.org)

Thanks.

Hey Andrew,

When can we expect this plugin to be compatible with WordPress 2.8’s widget framework? The sole reason I’m holding back my site’s upgrade to the beta versions is because I love Widget Cache too much. :-D

Hi Rishi,

I haven’t test wp 2.8 beta yet, I still look forword to a RC version. but I do notice the widget.php been changed a lot.

Andrew

Thanks for the fast reply buddy! Wish I could help with the testing, but my PHP skills are rather… nonexistent. :-D

hi tehre. just wanted to point out, that there are quite a few questions open in the wordpress forums about your plugin, maybe yo ucan have a look at them too? http://wordpress.org/tags/wp-widget-cache

How can I test to see if my widgets are actually being cached? I change things but I can’t really tell a difference. Is there a testing method other than looking at stats?

Jun 10th, 2009
Andrew

Well June,

You can check the sql request times, visit http://wordpress.org/extend/plugins/wp-widget-cache/faq/ for more details.

Or you can add some debug code yourself, that’s the most dependable way to make sure some widget is cached.
Here’s the debug code:
on the line 514 of widget-cache.php,

call_user_func_array($callback, $params);

this line is the real widget func, you can add a line before, out put some comments,like this: echo “<!–Do Widget Func–>” ;

Then you can see different pages having the same widgets, if this comment not output always, that’s means it’s cached.

Regards,
Andrew

Andrew,

Your plugin rocks man!!
Is there a way to clean the cache selectively instead of cleaning the cache of all the plugins?

Thanks,
Mahesh

Hi Mahesh,

I’m not sure why you want this, but there’s a way, on the widget setting page, there’s a delete link just near the expire time input box.

Andrew
