So far I got this, but I’m unsure on how to retrieve an Advance custom fields from the post and replace ‘Toy-‘ with it.
function add_custom_title( $data, $postarr )
{
if($data['post_type'] == 'toy')
{
if(empty($data['post_title']))
{
$count = get_option('toy_count', 1);
$data['post_title'] = 'Toy-' . $count++;
update_option( 'toy_count', (int) $count );
}
}
return $data;
add_filter('wp_insert_post_data', 'add_custom_title', 10, 2 );
Hi @elbowpham
I would fist look at the varible $data and find out what you can play with. This is more commonly known as variable ‘debugging’. You can do this like so:
<?php
echo '<pre>';
print_r($data);
echo '</pre>';
die;
?>
Using this code will display the contents of $data.
You should see that the custom field value is something like:
$data['fields']['field_1235678']
The field_1235678 is the field_key which you can find from the field edit screen, or simply just figure it out from the posted $data

Below is what I get out from the following command. However I don’t see any any fields types.
I have a custom post type set up and I’m using acf with it if that helps.
print_r($data);
Array
(
[post_author] => 1
[post_date] => 2013-08-01 15:02:51
[post_date_gmt] => 2013-08-01 15:02:51
[post_content] =>
[post_content_filtered] =>
[post_title] =>
[post_excerpt] =>
[post_status] => publish
[post_type] => toy
[comment_status] => closed
[ping_status] => closed
[post_password] =>
[post_name] => toy-124
[to_ping] =>
[pinged] =>
[post_modified] => 2013-08-01 15:02:57
[post_modified_gmt] => 2013-08-01 15:02:57
[post_parent] => 0
[menu_order] => 0
[guid] => http://toy.dev/?post_type=toy&p=211
)
Hi @elbowpham
The $data must only contains the post data, not the $_POST data.
Perhaps you need to look in the $_POST array
Am I correct in saying the following:
If I named my field field_season for example, but it shows up in $_POST as field_5470f6551f722, this key is the internal reference that ACF will always use for field_season and it’s safe writing logic based on field_5470f6551f722 always referring to field_season?
