Get values ​​of custom fields in the filter on wp_insert_post_data

Hi everyone , thanks for reading.

Environment :

Wordpress Plugin + Additional Custom Fields

Problem:

I searched for several hours, and I cannot find the correct syntax to do the following:

When you publish a new message, get the value of the custom field to automatically replace the message header with this value. Example: I create a message and set the '10am' to my time 'user field. The message header is automatically replaced with "10 a.m."

Example:

So, I add a filter with the following:

add_filter('wp_insert_post_data', 'change_title') ;

function change_title($data)

{

    $time = XXX ; // How should I get this custom field value ?

    $new_title = 'Topic created at'.$time ;

    $data['post_title'] = $time ;

    return $data;

}

add_action('save_post', 'change_title');

function change_title($post_id) {
    $time = get_field('time',$post_id);
    $post_title = 'Topic created at '. $time;

    // unhook this function so it doesn't loop infinitely
    remove_action('save_post', 'change_title');

    // update the post, which calls save_post again
    wp_update_post(array('ID' => $post_id, 'post_title' => $post_title));

    // re-hook this function
    add_action('save_post', 'change_title');
}
