Hi, I'm having exact same issue as the person who started this thread. metamod shows the correct module only if I turn off SEF urls in Joomla. I'm using Joomla 1.5.20 with default Joomla sef.

SITUATION: I have a category list link on main menu. When I click any of the category list links, I want to add a left col module to the category article. Since Joomla is not capable of displaying a module on a category list article page, I am using metamod to do that. It works perfectly unless I turn on Joomla SEF URLs. Then it doesn't work and the module does not display.

Here is metabod debug info for page:

Page Identification
The PHP code below may be used to help MetaMod to identify the exact page that you are viewing. For help using this feature, please click here.
if (
$option == 'com_content'
and $view == 'article'
and $id == '60:nashville-sales-career-fair-wednesday-august-18th'
and $Itemid == '56'
) return XXX; /* replace XXX with the module ID or position to display */
MetaMod debug info:
$option: com_content
$view: article
$id: 60:nashville-sales-career-fair-wednesday-august-18th
$Itemid: 56
$timezone: default
$language: en-us
$language_code: en
$language_region: us
Including modules: 90

Here is module php code:

$category_id = null;
if ( $option == "com_content" ) {
  if ( $view == "category" ) {
   /* category list pages (blog or list style) */
   $category_id = (int)$id;
  } else if (array_key_exists("catid",$_REQUEST)) {
   /* if the category id is in the URL */
   $category_id = (int)JRequest::getInt("catid",0);
  }
  if ( $category_id === null && $view == "article" ) {
   /* if it's an article page without the catid mentioned in the url */
   $nullDate = $db->Quote( $db->getNullDate() );
   $my_id = $db->Quote( $db->getEscaped( (int)$id ) );
   $jnow  =& JFactory::getDate();
   $now    = $db->Quote( $db->getEscaped( $jnow->toMySQL() ) );
   $query = "SELECT  title,  id,  catid "
       . " FROM #__content WHERE id = $my_id AND state = 1"
       . " AND ( publish_up = $nullDate "
       . " OR publish_up <= $now )"
       . " AND ( publish_down = $nullDate "
       . " OR publish_down >= $now  )";
   $db->setQuery( $query, 0, 1 );
   $row = $db->loadObject();
   $category_id = $row->catid;
  }
}
/* Now customise any of the following rules for your use.
* $category_id will correspond to the category id of the
* article being displayed (if one is being displayed!)
*/
if ($option == "com_content" and $view == "article" and $category_id == 37) return 90;/* on category 1, return module 55 */

Below is debug info.

Hi, Thanks for response. Strangely, it started working. Only think I can think of is some weird caching issue. Anyway, glad it works now.
