Set custom post type title by acf?

  • So far I got this, but I’m unsure on how to retrieve an Advance custom fields from the post and replace ‘Toy-‘ with it.

    function add_custom_title( $data, $postarr ) 
        if($data['post_type'] == 'toy') 
                $count = get_option('toy_count', 1);
                $data['post_title'] = 'Toy-' . $count++;
                update_option( 'toy_count', (int) $count );
        return $data;
    add_filter('wp_insert_post_data', 'add_custom_title', 10, 2 );
  • Hi @elbowpham

    I would fist look at the varible $data and find out what you can play with. This is more commonly known as variable ‘debugging’. You can do this like so:

    echo '<pre>';
    echo '</pre>';

    Using this code will display the contents of $data.
    You should see that the custom field value is something like:


    The field_1235678 is the field_key which you can find from the field edit screen, or simply just figure it out from the posted $data


  • Below is what I get out from the following command. However I don’t see any any fields types.

    I have a custom post type set up and I’m using acf with it if that helps.

  • Hi @elbowpham

    The $data must only contains the post data, not the $_POST data.

    Perhaps you need to look in the $_POST array

  • Thanks a lot elliot.

  • Am I correct in saying the following:

    If I named my field field_season for example, but it shows up in $_POST as field_5470f6551f722, this key is the internal reference that ACF will always use for field_season and it’s safe writing logic based on field_5470f6551f722 always referring to field_season?
