  • Hello John,
    I read the link but i do not really understand. My English is not good and i work with WP Just recently.
    I try some like this:

    function my_acf_save_post( $post_id ) {
        // array of field values
        $fields = $_POST['acf'];
        // specific field value
        $field = $_POST['acf']['luc_nham'];  // 'luc_nham' is an array fields i need to get
    add_action('acf/save_post', 'my_acf_save_post', 1);
    function tess_fields()
        $id = get_the_ID();
        $fields = my_acf_save_post($id);
    add_shortcode('tess', 'tess_fields');

    Then i try to edit some fileds in a post, but alway return null. I dont know exactly i need to do. Can you help me an clearn example.

    Many thanks!
