Передать id юзера в acf_form( );

Нужно получить id юзера и только после этого создать от его имени пост, попутно не перезагружая страницу в момент логина или регистрации

$.ajax({
            type: 'POST',
            url: ajaxscript.ajax_url,
            data: { 
                action: 'ajaxlogin', 
                username: 'Mevzu113341',
                user_email: '[email protected]',
                new_user_email: '[email protected]',
                password: 'Aa1357aa'  },
            success: function(data){
                
                $.ajax({
                    type: 'POST',
                    url: ajaxscript.ajax_url,
                    data:{
                        user_email: '[email protected]',
                    },
                    success: function(body){
                        console.log(body)
                        $('input[value="Submit Book"]').click()
                        
                    }
                })
            },
            error: function(data){
                $('input[value="Submit Book"]').click()
            }
        })

Это AJAX запрос в function.php

Вот сам код с function.php:

$user_signon = wp_signon( $info, false );
    if ( is_wp_error($user_signon) ){
        $new_user_name = $_POST['username'];
        $new_user_email = $_POST['user_email'];
        $new_user_password = $_POST['password'];
        $user = get_user_by( 'email', $new_user_email );
        $userId = $user->ID;
        $user_data = array(
            'user_email' => $new_user_email,
            'user_pass' => $new_user_password,
            'user_login' => 'user',
            'role' => 'author'
            );
        $user_id = wp_insert_user($user_data);
            if (!is_wp_error($user_id)) {
            // echo 'we have Created an account for you.';
            $credentials = array(
              'user_login' => $new_user_email,
              'user_password' => $new_user_password,
            );
            wp_signon( $credentials );
            $userS = get_user_by( 'email', $new_user_email );
            $userIDs = $userS->ID;
            echo $userIDs;
            } else {
              if (isset($user_id->errors['empty_user_login'])) {
                $notice_key = 'User Name and Email are mandatory';
                wp_signon($user_data);
                print_r($user_id);
                
                } elseif (isset($user_id->errors['existing_user_login'])) {
                  $credentials = array(
                      'user_login' => $new_user_email,
                      'user_password' => $new_user_password,
                    );
                    wp_signon( $credentials );
                    $userS = get_user_by( 'email', $new_user_email );
                    $userIDs = $userS->ID;
                    echo $userIDs;
                } else {
                echo'Error Occured please fill up the sign up form carefully.';
                }
            }
    } else {
        echo 'error';
    }

код страницы на которой присутствует acf_form();

   if(is_user_logged_in()){
    $current_user_id = get_current_user_id();
    $new_post = array(
        'post_id' => 'new_post',
        'post_author' => $current_user_id,
                'field_groups' => array(452, 470), // Used ID of the field groups here.
                'post_title' => true, // This will show the title filed
                'post_content' => false, // This will show the content field
                'form' => true,
                'new_post' => array(
                    'post_type' => 'post',
                    'post_status' => 'draft' // You may use other post statuses like draft, private etc.
                ),
                'return' => '%post_url%',
                'submit_value' => 'Submit Book',
    );
} else{
    $new_user_email = $_POST['user_email'];
    $user = get_user_by( 'email', $new_user_email );
    $userId = $user->ID;
    $new_post = array(
        'post_id' => 'new_post',
        'post_author' => $userId,
                'field_groups' => array(452, 470), // Used ID of the field groups here.
                'post_title' => true, // This will show the title filed
                'post_content' => false, // This will show the content field
                'form' => true,
                'new_post' => array(
                    'post_type' => 'post',
                    'post_status' => 'draft' // You may use other post statuses like draft, private etc.
                ),
                'return' => '%post_url%',
                'submit_value' => 'Submit Book',
    );
}
    acf_form( $new_post);

мне нужно после получения id юзера в function.php отправить его в acf_form(); Всем заранее спасибо за ответы
