Hi,

I need to use acf field to create the title of my custom post. All working, but I have a problem.

Here is my code:

function dimension_update_postdata( $value, $post_id, $field ) {
$code = get_field(‘dimension_code’, $post_id);
$no = get_field(‘dimension_no’, $post_id);

$title = $no .’ – ‘. $code;
$slug = sanitize_title( $title );

$postdata = array(
‘ID’ => $post_id,
‘post_title’ => $title,
‘post_type’ => ‘dimension’,
‘post_name’ => $slug
);

wp_update_post( $postdata );

return $value;
}
add_filter(‘acf/update_value/name=dimension_code’, ‘dimension_update_postdata’, 10, 3);
add_filter(‘acf/update_value/name=dimension_no’, ‘dimension_update_postdata’, 10, 3);

My problem is : when I publish/save the post for the first time, only the first acf field (dimension_code) of my acf form is updated. When I’m going in the list of posts, my custom post have this title – HSL, the first field is not there. But if I return to edit my post and I save again my post title is ok (eg. 644 – HSL).

What happening, why only the first field is use at the first time I save my post ?

If I replace the two add_filter by this (without the name field) :
add_filter(‘acf/update_value’, ‘dimension_update_postdata’, 10, 3);
The title of my post is ok the first time I save my post?!?
I don’t understand.

Anybody have an idea. I don’t if is a bug or only a problem with my code.

Config:
WP 4.2.2
WPML
ACF Pro (the last one)

Thanks

I’ve been using this…give it a try

//Auto add and update Title field:
  function my_post_title_updater( $post_id ) {

    $my_post = array();
    $my_post['ID'] = $post_id;

// custom post type
    $foo           = get_field('foo');

    if ( get_post_type() == 'foo' ) {
      $my_post['post_title'] = get_field('acf_title_slug');
    } 

    // Update the post into the database
    wp_update_post( $my_post );

  }
   
  // run after ACF saves the $_POST['fields'] data
  add_action('acf/save_post', 'my_post_title_updater', 20);
//END Auto add and update Title field:
