Reply To: sorting entries in repeater post object field

Hi @rudtek

The strolower() function is used to make the sorting insensitive.

If you want to sort the repeater, then you need to use the “session.” But if you want to sort the post object, then it should be “session_speaker.” I haven’t tested it with your setup, but it’s working on my post object field. Could you please share the JSON export file of your field group so I can test it up on my installation?

Also, could you please debug it like this:

function my_acf_sort_post_object( $value, $post_id, $field ) {
	
	// vars
	$order = array();
	
	// bail early if no value
	if( empty($value) ) {
		return $value;	
	}
	
	// populate order
	foreach( $value as $i => $post_id ) {
        $post_title = get_the_title($post_id);
		$order[ $i ] = $post_title;
	}
    
    echo "<pre>";
    print_r($value);
    echo "</pre>";
    
    echo "<pre>";
    print_r($order);
    echo "</pre>";
    
    $order_lowercase = array_map('strtolower', $order);
	
	// multisort
	array_multisort( $order_lowercase, SORT_ASC, SORT_STRING, $value );
	
	// return	
	return $value;	
}

add_filter('acf/load_value/name=session_speaker', 'my_acf_sort_post_object', 10, 3);

And on the front end, just execute the get_field() function like this:

get_field('session_speaker');

Thanks 🙂
