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 :

  1. If the plugin that needs to be updated is active, it is deactivated.
  2. The Plugin Updater retrieves the plugin’s page from WordPress.org and finds the download link.
  3. The new version is downloaded and extracted to the wp-content/plugins directory (this directory must be writable by the Updater plugin).
  4. 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.

  6. White Shadow says:

    Check your file permissions. For this plugin to work, /wp-content/plugins/ needs to be writable by PHP.

    Alternatively, use the WP built-in upgrader (this is the recommended approach).

  7. Oh I did, I ran it all the way to 777 & still get the error.

    How about the built-in upgrader then? This plugin has pretty much become obsolete since that was introduced.

    Hi there

    Trying to use OCPI on my Hostgator sites. Works great on all my other sites – Bluehost etc. But on HG I have tried it on 3 blogs, via the FF addon (just as I usually use it).

    On 1 I get:
    This url:
    http://omega-advisory.com/wp-admin/plugins.php?page=install_plugin&magic=0a2ea624c978024cfc0c8761886fcd65&installtype=autodetect&fileurl=http://media.fucoder.com/permalink_redirect/permalink_redirect-2.0.4.zip

    And this error page:
    Forbidden

    You don’t have permission to access /wp-admin/plugins.php on this server.

    Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
    Apache mod_fcgid/2.3.5 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 Server at omega-advisory.com Port 80

    +++++++++++++++++++
    On the second – much the same happens.

    On the third I get:

    this url
    http://shs100.net/wp-admin/plugins.php?page=install_plugin&magic=ec84057340d32e1f9e29777f1a906d29&installtype=autodetect&fileurl=http://media.fucoder.com/permalink_redirect/permalink_redirect-2.0.4.zip

    And the standard 404 page from WordPress: “Easy, tiger. This is a 404 page. ….” etc.

    I remember this happening once before the same – and the blog it was happening with I just gave up on.

    Now I want it on three… and it’s more of a pain. The common factor is: Hostgator.

    I have tried changing permissions – plugins folder, the 3 x plugin.php files in wp-admin, to 777 and the same result.

    Any more suggestions would be much appreciated – as I use your plugin loads – it is so useful.

    Many thanks

    Hmm, I actually remember encountering a similar problem with other plugins, but I have no idea what was causing it.

    Just a guess: If you remove the “fileurl=xyz” parameter from the URL, does it still produces a 403/404?

  12. malc says:

    Hi again

    Thanks for fast response.

    If I take the &url…. out, I am taken to the wp login page. I log in and I am taken to the “Install From URL” page. If I put in the plugin url manually, it installs.

    So, the API or whatever it is 🙂 for the blog does not seem to work.

    Maybe just a Hostgator thing…?

  13. White Shadow says:

    Yep, that’s what I expected. My guess would be that Hostgator uses some kind of a security module that blocks URLs which contain other URLs. You can test that hypothesis by trying to open this made-up link :

    http://shs100.net/wp-admin/plugins.php?fakeurl=http://example.com/foo.zip

    If I’m right, it will also produce an error response. Otherwise, it’ll just display your “Plugins” page.

  14. Malc says:

    Hi mate – you are right – it gives a 404. I will contact HG and see if they have a solution or workaround.

    Thanks for feedback.

    Malc

  15. malc says:

    OK – HG sorted it. As you said it was security. FYI they had to enable a mod_security rule. Done in 5 mins. Thanks, Malc

    Is there a reason that OCPU uses a homebrew Zip handler? It takes several minutes (read: 10+) to update a single plugin, because it spends most of it’s time in “privReadEndCentralDir”. It’d be nice if it just used a faster Zip handler if available…
