ACF Form creates Pages after Post creation

Hello,

Sorry for the late answer, haven’t seen it before, as the original ticket has been resolved. You should create a new ticket when discussing a new topic, it’s easier for me to keep track of questions.

For your question, the query_var that is generated by the Post Action is an array version of the WP Post Object (see: https://developer.wordpress.org/reference/functions/get_post/#comment-876).

As you can see, the post_author key return the author ID (as of in the database). You’ll also see that in the “Cheatsheet” tab in the ACF Extended Form UI. Screenshot: https://i.imgur.com/YboRXXi.png

If you want to add your own custom key & data inside the query_var returned by the Post Action, you can use the following filter:

add_filter('acfe/form/query_var/post', 'my_acfe_form_post_query_var', 10, 6);
function my_acfe_form_post_query_var($post_object, $post_id, $post_action, $args, $form, $action){
    
    // Get author infos. See: https://developer.wordpress.org/reference/functions/get_user_by/
    $user = get_user_by('ID', $post_object['post_author']);
    
    // Add our own custom key & data
    $post_object['post_author_name'] = $user->display_name;
    
    // return
    return $post_object;
    
}

This will add the key post_author_name, so you can use the following template tag in your e-mail: {query_var:add-konzert:post_author_name}.

Note: I see that you defined a custom post slug, which is identical to the post title. That is not necessary, as WordPress will automatically convert the post title to a slugified version for the slug. You should use it in case you want a different slug.

For example My Post Title will be automatically converted to my-post-title for the slug. So you can leave it as “Default” 😉

Have a nice day!

Regards.
