Home Forums Backend Issues (wp-admin) Set post publish date by custom field? Reply To: Set post publish date by custom field?

  • Hi! This done the job for me :
    Paste this function on your functions.php theme.

    // Save ACF custom field to date-time post
    function my_acf_save_post( $post_id ) {
        $acfDate = get_field('initial_time_var', $post_id);
        //Test if you receive the data field correctly:
        //echo $acfDate;
        //exit (-1);
        $my_post = array();
        $my_post['ID'] = $post_id;
        $my_post['post_date'] = $acfDate;
        wp_update_post( $my_post );
    add_action('acf/save_post', 'my_acf_save_post', 20);

    Notes: Be sure to give the correct post id variable ($post_id) and the correct time variable (initial_time_var for me)

    Important: Set the field type (data picker) in your ACF panel to return this custom exact format: Y-m-d H:i:s
