Joomla Extensions

In joomla1.0.x, If the active menu links to com_content, we can use the following code to get the active menu linked content's section id and category Id.

global  $Itemid;
$activeMenuItemId=$Itemid;
$params=array();
$sql = "SELECT m.*"
	. "\n FROM #__menu AS m"
	. "\n WHERE id = ".$activeMenuItemId
	. "\n AND published = 1";
$database->setQuery( $sql );
$menuRows = $database->loadObjectList();
if(count($menuRows)){
	$linkParts=explode('?',$menuRows[0]->link);	   
	$parts=explode('&',$linkParts[1]);	       
	foreach($parts as $p){
	    $nv=explode('=',$p);    
	    $params[$nv[0]] = $nv[1];
	}  

$isContentMenu=0;	
if($params['option']=='com_content'){
   $isContentMenu=1;
	if($params['task']=='section'){//section
	    $secid=$params['id'];
	    unset($catid);
	}else if($params['task']=='category'){//category
	   $secid=$params['sectionid']; 
	   $catid=$params['id']; 
	}else{//article
		$articleId=$params['id']; 
		$sql = "SELECT c.sectionid,c.catid"
			. "\n FROM #__content AS c"
			. "\n WHERE c.id = ".$articleId;
		$database->setQuery( $sql );
		$sectionCat = $database->loadObjectList();
		if(count($sectionCat)){
		  $secid=$sectionCat[0]->sectionid;
		  $catid=$sectionCat[0]->catid;
		}
	}//end task

}//end option
}//end menu
