We have a custom post type that needs no title typed in by the user. I don’t need the post_title field in front end form, but i need in backend based on the custom field.

I’m use ACF PRO

Here it’s my code for front end form

<?php
	
	acf_form(array(
		'post_id'		=> 'new_post',
		'field_groups'       => array(608),
		'post_title'	=> false,
		'post_content'	=> false,
		'new_post'		=> array(
			'post_type'		=> 'companii',
			'post_status'	=> 'draft',
		),
		'submit_value'       => 'Inscrie companie',
	));
	
	?>

And functions.php

add_filter('acf/pre_save_post' , 'my_pre_save_post' );
function my_pre_save_post( $post_id ) {

if( $post_id == 'new_post' ) {

// data send by POST in form
$title = $_POST['fields']['field_55bf0fe0a0a81'];

// Default data post
$post = array(
'post_status'	=> 'draft',
'post_type'		=> 'companii',
'post_title'	=> 'Compania |'.$title,
);	
// action for update
$post_id = wp_insert_post( $post ); 

}	
}

Can you help me ?

Thanks in advanced

Use a post ID of something other than new_post. When you use that ID, ACF automatically creates the new post before your pre save post is run. You could for example use new_companii and then test for this ID is your filter.

Also, you need to return the value of $post_id at the end of your function

return $post_id;

Did you resolve this as I’m trying to do the same.

Thanks

I’m having the same issue. It was working perfectly fine in v4, but something has broken in v5.

This is my code on my page template to show the form:

<?php acf_form(array(
      'field_groups' => array('group_59398ef696c50'),
  		'post_id'		=> 'new_universe',
  		'post_title'	=> false,
  		'post_content'	=> false,
  		'new_post'		=> array(
  			'post_type'		=> 'universe',
  			'post_status'	=> 'publish'
  		),
      'submit_value' => 'Create'
		)); ?>

and this is my pre_save_post function

function create_universe_form( $post_id ) {
  // bail early if not a new post
  if( $post_id !== 'new_universe' ) {
    return $post_id;
  }
  // vars
  $title = $_POST['acf']['field_59398f1d71f62'];
  // Create a new post
  $post = array(
    'post_status'	=> 'publish',
    'post_type'		=> 'universe',
    'post_title'	=> $_POST['acf']['field_59398f1d71f62'],
  );
  // insert the post
  $post_id = wp_insert_post( $post );
  // Update $_POST Return
  $url = get_permalink($post_id);
	$_POST['return'] = ($url);
  // return the new ID
  return $post_id;
}

add_filter('acf/pre_save_post' , 'create_universe_form', 1, 1 );

Currently, it is properly saving/updating the URL/slug, but not the actual title.
