我正在尝试使用php文件中的extern表单创建新的Wordpress用户。 Leerling是学生的荷兰人，而leerling是我使用用户角色插件创建的角色。表单生成的所有用户都需要具有leerling角色。
我使用以下代码尝试这样做：
<?php
// Maakt een connectie met de database
$con = mysqli_connect("localhost", "root", "", "scoreplugin_db");
if (!$con) {
die("Connection failed: " . mysqli_connect_error());
}
// Haalt gegevens uit het registratieformulier, en genereert overige gegevens
if (isset($_POST['btn-signup'])) {
$uname = mysqli_real_escape_string($con, $_POST['uname']);
$achternaam = mysqli_real_escape_string($con, $_POST['achternaam']);
$upass = wp_hash_password(mysqli_real_escape_string($con, $_POST['pass']));
$datum = mysqli_real_escape_string($con, $_POST['datum']);
$email = mysqli_real_escape_string($con, $_POST['email']);
$basisschool = mysqli_real_escape_string($con, $_POST['basisschool']);
$opleidingsduur = mysqli_real_escape_string($con, $_POST['opleidingsduur']);
$bsgroep = mysqli_real_escape_string($con, $_POST['bsgroep']);
$url = '#leerling';
$fullname = $uname . ' ' . $achternaam;
// Query's om alle user data in de database op te slaan
$userdata = "INSERT INTO wp_users (user_login,user_pass,user_nicename,user_email,user_url,user_registered,display_name) VALUES('$email','$upass','$uname','$email','$url','now()','$fullname')";
$userinfo = "INSERT INTO wp_users_info (user_voornaam,user_achternaam,user_geboortedatum,user_basisschool,user_opleidingsduur,user_groep) VALUES('$uname','$achternaam','$datum','$basisschool','$opleidingsduur','$bsgroep')";
// Voert bovenstaande query's uit
if (!mysqli_query($con, $userdata)) {
die('Error: ' . mysqli_error($con));
}
if (!mysqli_query($con, $userinfo)) {
die('Error: ' . mysqli_error($con));
}
// User ID ophalen om meta op te slaan
$newuserid = mysqli_insert_id($con);
echo "$newuserid";
// De rank die de gebruiker automatisch meekrijgt
$rank = 'a:1:{s:8:"leerling";b:1;}';
// Query's om usermeta op te slaan
$addusernickname = "INSERT INTO wp_usermeta (user_id,meta_key,meta_value) VALUES ('$newuserid','nickname','$uname')";
$adduserfirstname = "INSERT INTO wp_usermeta (user_id,meta_key,meta_value) VALUES ('$newuserid','first_name','$uname')";
$adduserlastname = "INSERT INTO wp_usermeta (user_id,meta_key,meta_value) VALUES ('$newuserid','last_name','$achternaam')";
$adduserrank = "INSERT INTO wp_usermeta (user_id,meta_key,meta_value) VALUES ('$newuserid','wp_capabilities', '$rank')";
$adduserlevel = "INSERT INTO wp_usermeta (user_id,meta_key,meta_value) VALUES ('$newuserid','wp_user_level', '0')";
$adminbar = "INSERT INTO wp_usermeta (user_id,meta_key,meta_value) VALUES ('$newuserid','show_admin_bar_front', 'false')";
// Voert de metaquery's uit
if (!mysqli_query($con, $addusernickname)) {
die('Error: ' . mysqli_error($con));
}
if (!mysqli_query($con, $adduserfirstname)) {
die('Error: ' . mysqli_error($con));
}
if (!mysqli_query($con, $adduserlastname)) {
die('Error: ' . mysqli_error($con));
}
if (!mysqli_query($con, $adduserrank)) {
die('Error: ' . mysqli_error($con));
}
if (!mysqli_query($con, $adduserlevel)) {
die('Error: ' . mysqli_error($con));
}
if (!mysqli_query($con, $adminbar)) {
die('Error: ' . mysqli_error($con));
}
}

将信息写入数据库。但在管理员中，用户角色保持为空。 （当我以管理员身份登录wp-admin并查看“用户”页面时，新用户没有任何角色。）
有谁能告诉我我做错了什么？
