Get full link from menu item field type

Question

I am developing my own slideshow component and module for Joomla. The component is used to select the slides along with captions and links etc. The module shows the slides.

In the component, for each slide I have enabled the option to add a link to each slide. The field type that I have used is the menu item field type http://docs.joomla.org/Menuitem_form_field_type

This seems to add the menu item id to the database for that particular slide.

My question is; how do I take this menu item id and then in the module use it to get the full menu item link? I will understand that I will probably have to search through the database to find the right menu item and then find the appropriate link but I am not quite sure where to start.

If anyone could point me in the right direction I would appreciate it.

Thanks :)

Answer 1

To get the ID which I assume you know already, you can use the following:

$itemid = $params->get('field_name');

To get the URL based on the ID, try this:

$itemid = $params->get('field_name'); //change the field name to whatever you have 

$app = JFactory::getApplication();
$menu = $app->getMenu();
$link = $menu->getItem($itemid)->link;

echo JRoute::_($link);

This will echo a SEF URL. If you want a standard URL then simply use echo $link;

Hope this helps

Answer 2

It can be done a little faster with less codding:

JRoute::_('index.php?Itemid='.$itemid);

This will return a relative url for the selected menu item.
