I'm working on a basic module to display an image carousel. The module itself works well, but what I want to do now is create a new folder called 'carousel' within the root 'images' folder when the module installs.

I've researched this a lot here (I apologise if this is a duplicate question) and from searches, but no matter what I try I can't get it to work.

I have this in the manifest file.


And I've created a script.php file. Here's what I have so far:

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

  class mod_CarouselInstallerScript
    function install($parent) 
      $destination = JPATH_SITE.'/'."images";
      $folder_name = "carousel";
      JFolder::create($destination .'/'. $folder_name, 0755);

I've tried various versions of this found here and in Joomla documentation.

What am I missing?

  • Are you sure it's even being executed? Can you try adding var_dump('foobar'); inside the function and check your Network tab in the browser console to see if you see that being returned?

  • Hi @Lodder, thank you for your reply. I've done as you suggested and, no it's not returned in the Network tab in the browser console.

  • In which case your class name may be incorrect. Can you provide the XML <name> value for your module?

  • Hi @Lodder - here it is - <name>RRM Carousel</name>

  • Try replacing class mod_CarouselInstallerScript with class mod_Rmg_carouselInstallerScript

Thank you to @Lodder for providing a solution, very much appreciated.

@Lodder suggested my class name may be incorrect and said to try 'replacing class mod_CarouselInstallerScript with class mod_Rmg_carouselInstallerScript'.

I changed my class to mod_RRM_carouselInstallerScript which solved the problem.
