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.

Check if the file/folder have a different owner or file permissions than the rest of the plugins. This can happen if the server configuration was changed since Contact Form 7 was first installed.
Also, the all-uppercase filename looks… suspicious. Is your server running Windows, or some flavour of Linux?

my web host tells me OneClick Plugin Updater is a SECURITY RISK.
they say the file:
do_update.php
and the variable:
$download_url
could be used for a successful exploit.
I doubt it. The script in question checks whether the user is logged in and has the required security privileges before doing anything. It also requires a so-called “nonce” variable to be set, which makes cross-site attacks impossible. It should be safe.

I just wanted to comment. Your content was informative to me and thanks.
hi, I recently did a backup on my WPDB and when I restored it and turned on my plugins I started receiving this error when going to the plugin page:
Warning: Invalid argument supplied for foreach() in /wp-content/plugins/one-click-plugin-updater/oneclick-plugin-updater.php on line 652
Warning: Attempt to assign property of non-object in /wp-content/plugins/one-click-plugin-updater/oneclick-plugin-updater.php on line 668
any idea?
Looks like an option wasn’t properly initialized. Should be fixed now.
I decided to just remove and reinstall the plugin. It’s working fine again =)
Thanks for this plugin, works great.

some problems here… when I install OCPU, I get these messages on my plugins page:
======
Warning: Invalid argument supplied for foreach() in /home3/proveiss/public_html/wp-content/plugins/one-click-plugin-updater/oneclick-plugin-updater.php on line 658
Warning: Attempt to assign property of non-object in /home3/proveiss/public_html/wp-content/plugins/one-click-plugin-updater/oneclick-plugin-updater.php on line 674
======
and then, if I try to update automatically any plugin, I get this error:
======
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 85 bytes) in /home3/proveiss/public_html/wp-includes/streams.php on line 69
======
any ideas? =(
I’ll upload an update to wordpress.org that might help.
On an unrelated note, are you sure you need this plugin? WordPress now has an automatic update feature built-in, so OCPU is mostly obsolete.
wordpress built-in won’t mass update nor will it “right-click-on-link” install plugins =)
the error when activating the plugin doesn’t show up anymore… but when I tried to delete some other plugin…
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 24 bytes) in /home3/proveiss/public_html/wp-includes/gettext.php on line 91
is there any enviroment specs I could provide to help with this?
Hmm, why would it run over the memory limit?… Frankly, I have no idea what could be wrong
and when I try to update something, it gets the same one:
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 71 bytes) in /home3/proveiss/public_html/wp-includes/gettext.php on line 91

I tried to avoid bugging you with a simple question but after spending quite a bit of time I’m trying to figure out why I get my websites 404 page after trying to install a plugin using the firefox extension.
When I enter the url provided into my browser the installation page appears but when trying to install the plugin I get the 404 page.
( I’m using thesis and the newest versions of wordpress, the once click installer plugin and firefox addon One-Click Installer for WP 1.1)
I know the answer is really pretty simple, I just haven’t found it yet.
ps I’m writing a a review (positive )and I’d really like to get this working soon.
Thanks for the great plugin
What is the actual URL in the address bar when you try to install the plugin and get a 404 page?
This is the address that for the 404:

Just checking in to see if you have a solution to my installation problem (above).
I’m really excited about the possibilities of what your plugin can do. I just need to get it working.
Thanks for your help.
