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.

Just to clarify, the “Add New” page is part of the WP core, not this plugin.
WordPress asks for your FTP credentials because it can’t directly create files in the ‘plugins’ directory (or at least it thinks so). You need to set the file permissions to allow PHP write access to that directory. Depending on your configuration, this might be 755 or 777.
If you can install plugins via the page created by this plugin (“Plugins -> Install a Plugin”) but the “Add New” page still asks you for your FTP info, it’s probably a bug in WordPress.
I have found an interesting discussion on
http://wordpress.org/support/topic/223144
regarding the checks made by wordpress.
I finally found what was the problem. WP is searching for the owner of the file, and I’m using it on a multiuser environment, so that’s why it wasn’t working.
Thank you! Without your help I wouldn’t have fixed it!

I can’t update Contact Form 7. Other plug-ins seem to update easily. This one won’t. I get this:
Can’t create file ‘contact-form-7/README.txt’ in ‘/home/hintysen/public_html/wp-content/plugins/’
The full installation log is below :

Okay.

Can’t create file contact-form-7/README.txt in /home/hintysen/public_html/wp-content/plugins/!
Main loop finished.
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.
