I'm trying to use wp_set_object_terms ref : http://codex.wordpress.org/Function_Reference/wp_set_object_terms while passing array for both the terms and taxonomy

for some reason i keep getting : Warning: Illegal offset type in isset or empty in /home1/stodeckc/public_html/clicktranslate/wp-includes/taxonomy.php on line 231

this is how i am trying to set it:

parents[] = array(
    'item_id' => 15,
    'app_name' => 'justanotherone'

foreach($parents as $parent){
    $cat_ids[$parent['item_id']] = (int)$parent['item_id'];
    $taxonomies[$parent['item_id']] = $parent['app_name'];
wp_set_object_terms( 42, $cat_ids,$taxonomies);

am i missing something ?


  • Why are you setting the array index?

  • The warning message shows the $taxonomies you pass to wp_set_object_terms might be empty or wrong type. Could you dump the $cat_ids and $taxonomies to see what are the values?

what i ended up doing:

foreach($this->parents as $parent){
            $taxonomies[] = $parent['app_name'];
        wp_delete_object_term_relationships( (int)$parent['item_id'], array_unique( $taxonomies ) );

        foreach($this->parents as $parent){
            $cat_id = (int)$parent['item_id'];
            $taxonomy = $parent['app_name'];
            wp_set_object_terms( (int)$parent['item_id'], $cat_id,$taxonomy, true);

This solution is a little longer but it worked and i couldn't spend more time searching the problem.
