This is a core hack. Files you change as described on this page will be overwritten during updates of Joomla!. For more information, see Core hack.

I have developed a hack to add the capacity to unzip and untar files to the Media Manager component of Joomla! 1.5. It works like the delete function: you check the file and you click on the icon to unzip the selected file. It generates a folder with the same name as the selected file.

This hack is available here at the end of the post. Just copy it at the root of your site. By hand it works like this.

Open the file administrator/component/com_media/views/media/view.html.php and after the line 106

    /* (...) */
    // Add a delete button
    $title = JText::_('Delete');
    $dhtml = "<a href=\"#\" onclick=\"MediaManager.submit('folder.delete')\"
      class=\"toolbar\">
                <span class=\"icon-32-delete\" title=\"$title\"
                  type=\"Custom\"></span>
                $title</a>";
    $bar->appendButton( 'Custom', $dhtml, 'delete' );
    /* (...) */

add

    /* (...) */
    // Add a Unzip button
    $title = JText::_('Unzip');
    $dhtml = "<a href=\"#\" onclick=\"MediaManager.submit('folder.unzip')\"
      class=\"toolbar\">
                <span class=\"icon-32-unarchive\" title=\"$title\"
                  type=\"Custom\"></span>
                $title</a>";
    $bar->appendButton( 'Custom', $dhtml, 'unzip' );
    /* (...) */

This adds the icon button in the Media Manager toolbar (at the top, near the delete button).

Then open the file administrator/component/com_media/controllers/folder.php and add after the delete function:

    /* (...) */
    function unzip() {
        global $mainframe;
 
        // Set FTP credentials, if given
        jimport('joomla.client.helper');
        JClientHelper::setCredentialsFromRequest('ftp');
 
        // Get some data from the request
        $tmpl    = JRequest::getCmd( 'tmpl' );
        $paths    = JRequest::getVar( 'rm', array(), '', 'array' );
        $folder = JRequest::getVar( 'folder', '', '', 'path');
 
        // Initialize variables
        $msg = array();
        $ret = true;
 
        if (count($paths)) {
            foreach ($paths as $path)
            {
                if ($path !== JFilterInput::clean($path, 'path')) {
                    JError::raiseWarning(100, JText::_('Impossible de
                      decompresser:').htmlspecialchars($path, ENT_COMPAT,
                      'UTF-8').' '.JText::_('WARNDIRNAME'));
                    continue;
                }
 
                $fullPath = JPath::clean(COM_MEDIA_BASE.DS.$folder.DS.$path);
 
                if (is_file($fullPath)) {
                    $ext = JFile::getExt(strtolower($fullPath));
                        $pathdir = $fullPath;
                        if($ext != 'gz') {
                            $pathdir = str_replace( ".".$ext, "",$pathdir);
                        }
                    else {
                        $pathdir = str_replace( ".".$ext, "",$pathdir);
                        $pathdir = str_replace( ".tar", "",$pathdir);
                    }
 
                    jimport('joomla.filesystem.*');
                    jimport('joomla.filesystem.archive');
                    JFolder::create($pathdir);
                    JFile::write($pathdir.DS."index.html", "<html>\n<body
                      bgcolor=\"#FFFFFF\">\n</body>\n</html>");
                    JArchive::extract($fullPath, $pathdir);
 
 
                } else if (is_dir($fullPath)) {
                    JError::raiseWarning(100, JText::_('Imossible de
                      decompresser:').$fullPath.' '.JText::_('Pas un fichier
                      ZIP'));
                }
            }
        }
        if ($tmpl == 'component') {
            // We are inside the iframe
            $mainframe->redirect('index.php?option=com_media&view=mediaList&
              folder='.$folder.'&tmpl=component');
        } else {
            $mainframe->redirect('index.php?option=com_media&folder='.$folder);
        }
    }
    /* (...) */

That's all. My hack uses the joomla.filesystem.archive library of Joomla! 1.5 and works with the zip, tar and gz extensions.
