Filtering by a parent object, such as a seciton, was previously a needlessly complicated process that involved setting up a parent filter and adding it to your main filter via add_parent, as show below:

    $sectionFilter =& pxdb_search::filter(DATATYPE_SECTION);    
    $sectionFilter->add_value('id', $Request->getVar('in_section'));
 
    $content_filter->add_parent($sectionFilter);

The latest CVS snapshot simplified add_parent by allowing it accept either a pxdb_search filter, a pxdb_record or descendant object, a numeric record id, or a record's idnum value. This makes it easier to filter by parent objects since any of the following are now valid calls. The add_parent() method will handle all the filtering internally.

    $content_filter->add_parent( $Section ); // seciton is a pxdb_record descendant
    or
    $content_filter->add_parent( $Section->get_id() ); 
    or
    $content_filter->add_parent( $pxdb_record->get_field( 'idnum' ) );
