Joomla one click updates in extension manager does not work for plugins

Thursday, October 13th, 2011

I developed Comparison Table plugin for Joomla. It has also one click update functionality but getting it work was quite a lot of work and debugging core joomla source code.

Official documentation for updateservers is here http://docs.joomla.org/Deploying_an_Update_Server

To make it short you must add updateservers tag to yuour plugin/component/module XML file

    <updateservers>
        <server type="extension" priority="1" name="Comparison Table updates">http://marguspala.com/joomla/comparisontable_update.xml</server>
    </updateservers>

Next you need to put together update XML. Required tags there are name, element, type, folder(for plugins), downloads, and version. Element must contain very same text as you have in install XML package files in main filename plugin/module/component value.

        <files>
            <filename plugin="comparisontable">comparisontable.php</filename>
        </files>

If you still get “There are no updates available at the moment. Please check again later.” then here is a few hints for debugging: (more…)

I see a need of basic functional Joomla plugin example. New developers can use this to get them started.

I made simple plugin for this that looks for tag in article and replaces it. Param’s, field and fieldset are also used.

Plugin Install: No plugin file specified

You might get error

Plugin Install: No plugin file specified

if you develop your own Joomla plugin. I managed to get such error when I finished module for Joomla but decided it is better to be implemented as content plugin and start to make conversion.

To fix it you must make sure you have group=”content” or whatever type your plugin is in your XML file extension/install part

 <install type="plugin" version="1.6" group="content">
