I am trying to add an Advance Custom Fields custom location rule to choose Theme Hybrid post templates. In my functions.php file I have the following code

if (!function_exists('acf_location_rules_types')) {
    function acf_location_rules_types( $choices ){
        $choices['Meta Data']['post_template'] = 'Post Template';

        return $choices;
    }
}

if (!function_exists('acf_location_rules_values_post_template')) {
    function acf_location_rules_values_post_template(){
        global $post;
        $templates = get_post_meta( $post->ID, '_wp_post_template', true );

        if( $templates ){
            foreach( $templates as $template ){
                $choices[ $template->meta_id ] = $template->meta_key;
            }
        }

        return $choices;
    }
}

if(!function_exists('acf_location_rules_match_post_template')){
    function acf_location_rules_match_post_template(){
        $current_field = get_post_custom_keys();
        $selected_field = (int) $rule['value'];

        if($rule['operator'] == "=="){
            $match = ( $current_field->meta_id == $selected_field );
        }
        elseif($rule['operator'] == "!="){
            $match = ( $current_field->meta_id != $selected_user );
        }

        return $match;
    }

When I try to choose this as a location rule I don’t get any matched values, what parameters am I passing that are wrong?

Hi @mojaray2k,

Thanks for the post.

Are your values getting retuned when you debug the data?

I would recommend you begin by debugging the functions line by line to identify where the error is occuring.

I have also noted you are passing the wrong variable on this line:

elseif($rule['operator'] == "!="){
            $match = ( $current_field->meta_id != $selected_user );
        }

It should be:

elseif($rule['operator'] == "!="){
            $match = ( $current_field->meta_id != $selected_field );
        }
