Getting post installation script to run for a module

Question

I've a module that I want to run a script post installation, post update etc.

I think this can be done by adding a script.php into the module zip file and then calling it in the installation file.

<scriptfile>script.php</scriptfile>

in the xml file to set up the script.

In the script.php I've some test type stuff:

            <?php
            // No direct access to this file
            defined('_JEXEC') or die;

            /**
             * Script file of HelloWorld module
             */
            class mod_W4cAccordionDisplayInstallerScript
            {

                /**
                 * Method to install the extension
                 * $parent is the class calling this method
                 *
                 * @return void
                 */
                function install($parent) 
                {
                    echo '<p>The module has been installed</p>';
                            $db = JFactory::getDbo();
                    $query = $db->getQuery(true)
                            ->update('#__update_sites')
                            ->set('extra_query = "ids=12354"')
                            ->where('name = "Accordian Display"');
                    $db->setQuery($query);

                    $db->execute();

                }

                /**
                 * Method to uninstall the extension
                 * $parent is the class calling this method
                 *
                 * @return void
                 */
                function uninstall($parent) 

I haven't copied the whole file since it's basically a copy of the joomla example.

When I run this by updating in the update then it says installation complete but it doesn't adjust the update sites table.

Any ideas where I might be going wrong

So I've now changed out the database update for

mail("[email protected]","My subject","user id is: ");

and put it into function postflight($type, $parent)

but there is no email response - I think that it's not loading and running the script :(

Figured it out - I had the wrong class name. I had removed all the _ characters like you normally do for class names but apparently you don't for this script. Hope this helps someone else. Thanks for the thoughts.

Answer 1

On update, you should use the update method like

function update($parent) 
{
    // on update stuff
}

You can find it in Joomla documentation Creating the extension script file

Hope it helps.

Answer 2

I changed the script to

            <?php
            // No direct access to this file
            defined('_JEXEC') or die;

            /**
             * Script file of HelloWorld module
             */
            class mod_w4c_accordion_displayInstallerScript
            {

                /**
                 * Method to install the extension
                 * $parent is the class calling this method
                 *
                 * @return void
                 */

The key to success was NOT removing the underscores - something you do with other areas of Joomla like in a helper.php file. Once I'd done this it worked without a problem.
