For a particular reason, I need to keep in the SEF URL only the alias of the item to have a URL like this www.mywebsite.com/**myItemAlias** but of course without creating a direct menu to the item because I need it to be automatic.

My router code :

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

/**
 * Routing class from com_wm
 *
 * @since  3.3
 */
class WmRouter extends JComponentRouterBase
{   
    /**
     * Build the route for the com_wm component
     *
     * @param   array  &$query  An array of URL arguments
     *
     * @return  array  The URL arguments to use to assemble the subsequent URL.
     *
     * @since   3.3
     */
    public function build(&$query)
    {
        $segments = array();

        // Get a menu item based on Itemid or currently active
        $params = JComponentHelper::getParams('com_wm');
        
        if (empty($query['Itemid']))
        {
            $menuItem = $this->menu->getActive();
        }
        else
        {
            $menuItem = $this->menu->getItem($query['Itemid']);
        }

        $mView = (empty($menuItem->query['view'])) ? null : $menuItem->query['view'];
        $mId = (empty($menuItem->query['id'])) ? null : $menuItem->query['id'];

I don't really know how to go about it, I think we need to change here :

//Handle View and Identifier
        switch($segments[0])
        {
            case 'webcasts':
                $vars['view'] = 'webcasts';
                if (is_numeric($segments[$count-1]))
                {
                    $vars['id'] = (int) $segments[$count-1];
                }
                elseif ($segments[$count-1])
                {
                    $id = $this->getVar('webcast', $segments[$count-1], 'alias', 'id');
                    if($id)
                    {
                        $vars['id'] = $id;
                    }
                }
                break;
            case 'webcast':
                $vars['view'] = 'webcast';
                if (is_numeric($segments[$count-1]))
                {
                    $vars['id'] = (int) $segments[$count-1];
                }
                elseif ($segments[$count-1])
                {
                    $id = $this->getVar('webcast', $segments[$count-1], 'alias', 'id');
                    if($id)
                    {
                        $vars['id'] = $id;
                    }
                }
                break;

  • You can only do this if the component is the home; for doing it on a website, regardless of the active menu item, you need a system plugin – Riccardo Zorn Nov 29 '20 at 0:10
  • Thanks, by any chance, you wouldn't have an example of a plugin that would help and guide me ? – Laurent Nov 29 '20 at 12:54
  • You want to use this for articles (as items) or any other type of items, products...? Do you want to use this system wise or specifically on a component? – Zollie Nov 29 '20 at 14:47
  • Hi, yes this is for a specific component and only for view items www.website/aComponentItem – Laurent Nov 30 '20 at 16:13

As I suggested in my comment, building a plugin for this may be an alternative solution worth pursuing.

In a system plugin, simply add code similar to the example below to intercept any calls. Rest assured the code below was not tested on animals.

  1. intercept onAfterRoute()
  2. ensure your code should really run there, as an example:
    • exclude administrator
    • exclude post
    • exclude task= urls
  3. parse the input, determine if you code is now appropriate, if so
    • output and die() or
    • redirect

This is just an example:

public function onAfterRoute() {
    // make sure you only run this plugin where it makes sense:
    if (JPATH_BASE == JPATH_ADMINISTRATOR) return;
    $app = JFactory::getApplication();
    $input = $app->input;
    // you may want to exclude certain pages, components, views ... 
    // then simply query the input object or access some $_SERVER variable

    if (empty($input->get('task'))) {
        // when you are satisfied this is not going to adversely affect any functionality, 
        // either output something and die(), 
        echo 'You are <a href="https://localhost">here</a>';
        die();
        // or redirect:
        $app->redirect('https://example.com');
    }
}

If you want to see it in action, this code was abridged from my own plugin: https://www.fasterjoomla.com/download/stripe/stripe-button-downloads
