Single Click Plugin Updater WordPress Plugin
This plugin extends the plugin update notification feature introduced in WordPress 2.3 by adding an “update automatically” link to update notifications. When you click the link, the new version of the corresponding plugin is downloaded and installed automatically. It also lets you know which plugins have update notifications enabled.
Update 06.04.2008 : Version 2.0.1 with much more features is out. More info here.

How It Works (In Detail)
To be able to display the new link this plugin will hide the original update notification and display a slightly modified one. Here’s what happens when you click the “update automatically” link :
- If the plugin that needs to be updated is active, it is deactivated.
- The Plugin Updater retrieves the plugin’s page from Wordpress.org and finds the download link.
- The new version is downloaded and extracted to the wp-content/plugins directory (this directory must be writable by the Updater plugin).
- If necessary, the updated plugin is re-activated.
All this happens in the background, so if everything works OK you’ll end up back at the “Plugins” tab. If there are any errors the plugin will display an error message and abort the upgrade.
Requirements
- WordPress 2.3 or newer.
- CURL library installed or allow_url_fopen enabled in php.ini. If you don’t know what that means, don’t worry – at least one of these is available on most webservers by default.
- The /plugins directory must be writable by WordPress. The exact file permissions depend on the server configuration. Read more about file permissions. 666 or 755 may be sufficient, and 777 will always work, though this is not recommended due to security risks.
The plugin has been tested and works under Firefox 2.x, Opera 9.x and, as of version 1.0.5, Internet Explorer.
Installation
To install the plugin, please follow these steps:
- Download the one-click-plugin-updater.zip file (below) to your computer.
- Unzip the file.
- Upload “one-click-plugin-updater” folder to the “/wp-content/plugins/” directory.
- Activate the plugin through the ‘Plugins’ menu in WordPress.
That’s it.

@Donal – In that case I’m out of ideas.
I get an Error 500 from my server, when trying to update plugins after installing the new one click version. I checked the permissions in my plugin folder and its set to 755, so it should work according to the manual. After that i check for the libcurl library and it’s also running on the server.
@Mirco – Unfortunately this “error 500″ is a very generic, non-descriptive and fairly rare error. It’s nigh impossible to tell why it happens unless you do some heavy research.
From what I’ve found after googling wordpress plugins & error 500, it appears that this error is usually caused either by an incorrect .htaccess file or by file permissions.
Take a look at what permissions the actual one-click-plugin-updater files have. I can’t say what, exactly, they need to be, but they should have the same permissions as other plugin’s files. For example, if you have Akismet working and akismet.php is 755, then all .php files in the one-click-plugin-updater directory should also have 755 permissions.
If that doesn’t help then .htacess would be the next thing to look at.
I seem to keep getting the same message:
Can’t create a temporary file ‘/var/tmp/PLGVUPqpR’.
The full installation log is below :

Okay.

That temp directory just doesn’t exist on the server, maybe I’m just missing a setting or something? Please help, and sorry for sounding like a noob.
@Ben – From the log I can tell what’s going on, but I don’t know why.
First the plugin tries to create the temp. file in “/tmp”, but apparently that directory doesn’t exist and tempnam() returns an emty string. This is not exactly what it (PHP) should do – it should instead create the file in the system’s default temp. folder.
So the the plugin tries again (because it’s persistent and tries to be reasonably failsafe), attempting to create the temporary file in it’s own directory which definitely must exist. But this time, for some inexplicable reason, the tempnam() function reports that it has created the temp. file in “/var/tmp”, which, according to your comment, doesn’t exist.
As far as I can tell it’s a PHP/server/configuration bug.
[Oh, the humanity. I should probably go get some sleep.]
@White Shadow – I have checked the chmod of the plugins and themes directory to 777 and snoopy says it’s okay on the upgrade settings page. Any other ideas?
Much appreciated.
@Troy – I still think the log in your previous comment clearly indicates a permission issue. Check the permissions on akismet/akismet.php; also check which user owns those files. Is safemode on?

[...] One Click Plugin Updater Upgrade plugins with a single click, install new plugins or themes from an URL or by uploading a file, see which plugins have update notifications enabled, control how often WordPress checks for updates, and more. By Janis Elsts. [...]
I noticed that disabling One Click Plugin Updater, Wordpress core update function works fine. Does this plugin enables any normally unused library?
@José LuÃs – I don’t think so, though it may affect the access permissions of other plugin files (when it updates them). Maybe that has something to do with it.
I like this plugin quite a lot – but two difficulties. First, in the More/Hide segment on the banner towards the top of my dashboard pages – this is what I get when I click “More”:
Cannot load one_click_miniguide.
Second – since One-Click Install has been subsumed into One-Click-Plugin-Updater – how does one use it to install a theme (in the description in the plugins menu, theme installation is mentioned). Or to install a new (rather than updated) plugin?
My apologies if the answer to these questions are staring me in the face – but I’m not getting it.
O.C.P.U. is still a great plugin – and will clearly save lots of time and energy – but I’m very lazy, and I want the features of One-Click Install, too.

@Jon Soroko – The problem with the miniguide is actually an oversight on my part; a bug. You can manually enable the miniguide in Plugins -> Upgrade Settings.
To install a plugin, go to Plugins -> Install a Plugin. Likewise, use Design -> Install a Theme for themes. Simple
I get the same message that Ben mentioned . . . and I’ve tried it on multiple sits with the same result. So I have reverted to One Click Install on all sites until the problem is resolved. I love One Click Install and have been using it for a long time, but this plug-in simply will not work.
@JHS – Okay, now I’m definitely going to fix it in the next update. Expect it sometime during next week.
@White Shadow – Safe mode is off and I have tried every combination of 775, 755 and 777 on all directories and files and still no luck…
@Troy – Might it be that you’re using suPHP or Suhosin (spelling?) and the problematic files/directories have a different owner or group than the updater’s files?
Hey,
As of version 2.4 I can’t upload new plugins/themes from web anymore, it gives me the error below. (when trying to install a random plugin as an example)

Any help would be much appreciated!
@Sam L – I am getting the exact same thing. I’ve tried the permissions thing. Nothing…ideas?
2.0.8 – 2.4 use the same version of PclZip, so that’s probably not the problem. An error like that might appear if the download was corrupted somehow, but then it should be only temporary – the update should work after a few tries. Besides, the download size shown in the log is correct, so I doubt it was corrupted.
If the bug was happening on my own server I’d hack the plugin to leave the temporary downloaded file in place and look at it (the .zip) myself to see why it doesn’t work. I’d also directly test PclZip on that file.
Obviously I can’t do any of that with your server, so I’ll only attempt to make the file extraction algorithm a bit more robust.
Version 2.4.1 fixed PCLZip error on updates (didn’t test on installation of new plugins yet).
But I had to set Plugin Updater Module to “Wordpress core”, since every time I ordered an update it just told me the plugin was “activated” but didn’t update at all…
@José LuÃs – I can guess why that is, but I don’t know how to fix that. Ah well.

Whenever a new plugin update is released and I use your plugin to update those plugins, it does not reactivate the plugins after updating and instead shows this error message:
Fatal error: Call to a member function dprint() on a non-object in /home/navjot/public_html/nspeaks/wp-content/plugins/one-click-plugin-updater/do_update.php on line 49
Though the plugins do get updated!
I am using Wordpress 2.6.1
@Navjot Singh – This can happen when you update this plugin along with other plugins (via “Upgrade All”). It’s a known issue and will be fixed eventually.
I just wanted to mention to other people getting this message:
Extracting files from /var/tmp/PLGy67yfX…
So far, the type is set to ‘plugin’.

PclZip failed!

Mine works, once I switch it to use ‘Wordpress Core’ updater in the Plugin Updater Options. Since everything other than the actual upgrade engine looks the same to me, I’m probably not going to fight with it, unless a lot of free time comes up . . .
I’m thinking it’s running into errors reading/writing from /var/tmp … /var doesn’t show up as an existing folder in my PHP File Manager. I’ll know more when I get into the backend . . . but that won’t be soon.

Hate to burst any bubbles but the one click updater does not work with WP 2.6.1 as far as I can tell. I constantly deactivates a plugin so the upgrade can be installed and then the install fails. I checked the directory permissions and all relevant directories are 755 so that should not be the issue.
The old one click installer did what it was supposed to do quite well and included zip unpack and ftp capabilities. Fortunately, I save all the stuff I install and and go back to the deprecated version!
Yes, yes.
i, too, get a error when trying to upgrade (still in WP v2.6, single click v2.3):
Fatal error: Call to a member function on a non-object in /homepages/15/d206252512/htdocs/watson/wp-content/plugins/one-click-plugin-updater/do_update.php on line 127
help! with some rarity it works, but even then i have to reenable the upgraded plugins individually. thanks for the great plugin, sorry to be that guy with the mysterious error…
@Neil –
I was having the same problem….switched over to “Wordpress Core” and the plugin updater works now.
