Hi friends,

ACF v.5.6.10.

I have a form to create a custom post type called “animal”.

<?php acf_form_head(); ?>
<?php get_header();
acf_enqueue_uploader();
 ?>

	<div id="primary" class="content-area">
		<div id="content" class="site-content" role="main">

			<?php /* The loop */ ?>
			<?php while ( have_posts() ) : the_post(); ?>

				<?php acf_form(array(
					'post_id'		  => 'new_post',
					'new_post'		=> array(
						      'post_type'		 => 'animal',
						      'post_status'	 => 'publish'
					),
					'submit_value'		=> 'Salvar'
				)); ?>

			<?php endwhile; ?>

		</div><!-- #content -->
	</div><!-- #primary -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>

In my functions.php i create the filter acf/pre_save_post to change the post_title to use a custo post field called Name.

add_filter('acf/pre_save_post' , 'my_pre_save_post', 10, 1 );

function my_pre_save_post( $post_id ) {

  $newTitle = $_POST['acf']['field_5b32f9debf71e'];

  // User is logged
  //if ( !is_user_logged_in() ) {
  //	return;
  //}

  // check if this is to be a new post
	if( $post_id != 'new_post' ) {
		return $post_id;
	}

  // Verify if is the post_type 'animal'
  if( get_post_type($post_id) == 'animal' ) {
      // Create a new post
      $post = array(
        'post_type'     => 'animal',
        'post_status'   => 'publish',
        'post_title'    => $newTitle
      );

      // insert the post // wp_update_post
  		$post_id = wp_insert_post($post);

      return $post_id;
  }  // end-of-if ==> if( get_post_type($post_id) == 'animal' )

  return $post_id;

}

So, when i verify the custom posts animal in admin area, the title is blank.

All examples i found use this code.

Thanks for the help.

Hi again friends,

I resolved this with the other hook:

add_action('acf/save_post', 'my_save_post', 20);
function my_save_post($post_id){

  if( get_post_type($post_id) == 'animal' ) {

    // Get the data from a field
    $new_title = get_field('nome', $post_id);

    // Set the post data
    $new_post = array(
        'ID'           => $post_id,
        'post_title'   => $new_title,
    );

    // Remove the hook to avoid infinite loop. Please make sure that it has
    // the same priority (20)
    remove_action('acf/save_post', 'my_save_post', 20);

    // Update the post
    wp_update_post( $new_post );

    // Add the hook back
    add_action('acf/save_post', 'my_save_post', 20);

  }

}

But the question is, why the code to insert post don´t work in acf/pre_save_post ???

Thank´s
