我正在尝试将名字、姓氏和公司名称添加到我的自定义注册页面。登记表几乎可以使用，但存在一个问题。

到目前为止，我已经获得了以下代码，但我无法注册名字、姓氏和公司名称。谁能帮帮我吗？

<?php if(!is_user_logged_in()) { ?>


<?php
if(get_option(\'users_can_register\')) {
//Check whether user registration is enabled by the administrator
?>

<?php

if($_POST)

    {
    //We shall SQL escape all inputs
    $username = $wpdb->escape($_REQUEST[\'username\']);
    if(empty($username)) {
        echo "ERROR... please type username";
        exit();
    }
    $email = $wpdb->escape($_REQUEST[\'email\']);
    if(!preg_match("/^[_a-z0-9-]+(\\.[_a-z0-9-]+)*@[a-z0-9-]+(\\.[a-z0-9-]+)*(\\.[a-z]{2,4})$/", $email)) {
        echo "ERROR... please valid email";
        exit();
    }
    $first_name = $wpdb->escape($_REQUEST[\'first_name\']);
    if(empty($first_name)) {
        echo "ERROR... please add first name";
        exit();
    }
    $last_name = $wpdb->escape($_REQUEST[\'last_name\']);
    if(empty($last_name)) {
        echo "ERROR... please add last name";
        exit();
    }
    $companyname = $wpdb->escape($_REQUEST[\'companyname\']);
    if(empty($companyname)) {
        echo "ERROR... please add company name";
        exit();
    }





    $pass1 = $wpdb->escape($_REQUEST[\'pass1\']);
$pass2 = $wpdb->escape($_REQUEST[\'pass2\']);
if ($pass1 != $pass2){
    echo "ERROR... password\'s does\'nt mach";
        exit();

}
$random_password = $pass1;
    $status = wp_create_user( $username, $random_password, $email );
    if ( is_wp_error($status) )
        echo "ERROR... username allready exist\'s";
    else {
        $from = get_option(\'admin_email\');
        $headers = \'Fra: \'.$from . "\\r\\n";
        $subject = "Registreringen er fullført";
        $msg = "Hi, you are now registered. Here is your username and password:\\n\\n$username\\n$random_password";
        wp_mail( $email, $subject, $msg, $headers );
        echo "Thank you for registering. You can now log inn.";
    }

    exit();

} else {
//Embed the register form and javascript here

?>
