I've created a couple of small plugins that I install on most of my websites. But new plugins are (fortunately) disabled by default when installed. I know it's only a couple of clicks to enable the plugin, but is it possible to make my plugin enable itself once the installation is done?


What I would recommend doing is creating an install script that executes a postflight function. This function is built into Joomla and will get executed after the extension has installed.

You could use something like this:

function postflight($type, $parent)
    // We only need to perform this if the extension is being installed, not updated
    if (strtolower($type) === 'install') 
        $db = JFactory::getDbo();
        $query = $db->getQuery(true);

        $fields = array(
            $db->quoteName('enabled') . ' = 1',
            $db->quoteName('ordering') . ' = 9999'

        $conditions = array(
            $db->quoteName('element') . ' = ' . $db->quote('plg_myplugin'), 
            $db->quoteName('type') . ' = ' . $db->quote('plugin')



For more information on the script file, have a read of the Joomla Documentation:


Hope this helps

  • I believe that 1 and 9999 are integers and there is no need for type casting ;) – Farahmand Sep 27 '14 at 8:26
  • @Farahmand - It can be used but I suppose not a major requirement. I actually asked a question about this a while back: joomla.stackexchange.com/questions/3738/… .. not sure why using type casting deserves a downvote though as the concept/approach is correct – Lodder Sep 27 '14 at 9:56

You can create a plugin like this:

class plgExtensionEnableMyPlugins extends JPlugin
    public function onExtensionAfterInstall($installer, $eid)
        if ($eid)
            $db = JFactory::getDbo();
            $db->setQuery("UPDATE #__extensions SET `enabled` = 1 WHERE `extension_id` = $eid AND `type` = 'plugin'");

Install and enable the above plugin before installing your plugins.

  • You are suggesting using an additional plugin to perform this action? So what if I'm a user downloading @johan's plugin and I expect it to auto publish? Will he expect me to install this plugin you mentioned before downloading his? – Lodder Sep 26 '14 at 13:32
  • @Lodder, The question is about a "couple" of plugins that created by johan and he wants to install on "his" websites. If he had said the conditions you mentioned, my answer was something else ;) – Farahmand Sep 27 '14 at 8:21
  • @Farahmand, I do use the plugins mostly on sites I develop, but still, installing and enabling a plugin in order to auto-enable a couple of others seems a little overkill. But thanks for the code. – johanpw Sep 27 '14 at 10:40
  • @johanpw, No problem. Personally I prefer to use a plugin instead of to write postflight functions for all of my plugins. I believe that it's not an overkill. I can uninstall/disable the plugin as soon as I installed all of my plugins. Hope this helps people with similar case. – Farahmand Sep 27 '14 at 10:52
