Joomla: get category ID in template

I just needed to specify special layout for the articles of selected categories. I was looking for some solution online, but none of them worked. Mostly you can find this:

JRequest::getInt('catid');

or

JRequest::getInt('catid', '', 'get');

Maybe they worked in some other version of Joomla, but only working code I found is this (little modified by me to return integer values):


function getCategory() {
$iId = JRequest::getVar('id',0);
$database = &JFactory::getDBO();
if(JRequest::getVar('view', 0) == "section"){
return (int) JRequest::getVar( 'id', 0);
}else if(Jrequest::getVar( 'view', 0) == "category"){
$sql = "SELECT id FROM #__categories WHERE id = '$iId'";
$database->setQuery( $sql );
$row=$database->loadResult();
return (int) $row;
}else if(Jrequest::getVar('view', 0) == "article"){
$temp = explode(":",JRequest::getVar('id',0));
$sql = "SELECT catid FROM #__content WHERE id = ".$temp[0];
$database->setQuery( $sql );
$row=$database->loadResult();
return (int) $row;
}
}
$categoryId = getCategory();

  2. Hi Dominic,
    thx 4 ur comment. I am using this template:
    Twenty Ten 1.2 by the WordPress team
    it is basic template of the WordPress installation.
    And about plugins I would list those basic:
    All in One SEO Pack
    Custom Tag Cloud Widget
    FD Feedburner Plugin
    jQuery Lightbox
    ShareThis
    Syntax Highlighter for WordPress
    Twitter Widget Pro
    and finally
    WPtouch (this displays custom mobile theme if my blog is being accesed from mobile device)

    Cheers
    Luke
