获取钩子的当前页面ID

Question

I use a hook from the plugin Formidable Pro (frm_to_email) where I absolutely need to have the ID of the current page (for Advanced Custom Fields). As the code is located in function.php, it seems impossible for me to retrieve it. What can I do to get this value?

function custom_set_email_value($recipients, $values, $form_id, $args){
    global $post;
    $profil_obj = get_field('profil_obj', $post->ID); // If I put the ID directly (10 for example), it works

    if( $form_id == get_field('popup_form_id', 'option') && $args['email_key'] == get_field('popup_email_id', 'option') ){
        if($profil_obj) {
            foreach( $profil_obj as $post) {
                setup_postdata($post);
                $recipients[] = get_field('profil_email', $post->ID);
            }
        }
        wp_reset_postdata();
    }
    return $recipients;
}
add_filter('frm_to_email', 'custom_set_email_value', 10, 4);

You should be able to get the post ID at that stage from the URL, with url_to_postid():

<?php
$scheme  = (!isset($_SERVER["HTTPS"]) || $_SERVER["HTTPS"] === "off") ? "http" : "https";
$url     = "$scheme://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
$post_id = url_to_postid( $url );
