Нужно добавить еще одно текстовое поле в таблицу базы данных

Я использую код UserCake для решения управления пользователями.
Мне нужно добавить еще одно новое поле в качестве «mobile1» в базе данных.

Поэтому я добавил новый столбец как «mobile1» в пользовательской таблице. И включено текстовое поле
в файле register.php.

<?php
/*
UserCake Version: 2.0.2
http://usercake.com
*/class User
{
public $user_active = 0;
private $clean_email;
public $status = false;
private $clean_password;
private $username;
private $mobile1;
private $displayname;
public $sql_failure = false;
public $mail_failure = false;
public $email_taken = false;
public $username_taken = false;
public $displayname_taken = false;
public $activation_token = 0;
public $success = NULL;

function __construct($user,$display,$pass,$email,$mobile1)
{
//Used for display only
$this->displayname = $display;

//Sanitize
$this->clean_email = sanitize($email);
$this->clean_password = trim($pass);
$this->username = sanitize($user);
$this->mobile1 = sanitize($mobile1);

if(usernameExists($this->username))
{
$this->username_taken = true;
}
else if(displayNameExists($this->displayname))
{
$this->displayname_taken = true;
}
else if(emailExists($this->clean_email))
{
$this->email_taken = true;
}
else
{
//No problems have been found.
$this->status = true;
}
}

public function userCakeAddUser()
{
global $mysqli,$emailActivation,$websiteUrl,$db_table_prefix;

//Prevent this function being called if there were construction errors
if($this->status)
{
//Construct a secure hash for the plain text password
$secure_pass = generateHash($this->clean_password);

//Construct a unique activation token
$this->activation_token = generateActivationToken();

//Do we need to send out an activation email?
if($emailActivation == "true")
{
//User must activate their account first
$this->user_active = 0;

$mail = new userCakeMail();

//Build the activation message
$activation_message = lang("ACCOUNT_ACTIVATION_MESSAGE",array($websiteUrl,$this->activation_token));

//Define more if you want to build larger structures
$hooks = array(
"searchStrs" => array("#ACTIVATION-MESSAGE","#ACTIVATION-KEY","#USERNAME#"),
"subjectStrs" => array($activation_message,$this->activation_token,$this->displayname)
);

/* Build the template - Optional, you can just use the sendMail function
Instead to pass a message. */

if(!$mail->newTemplateMsg("new-registration.txt",$hooks))
{
$this->mail_failure = true;
}
else
{
//Send the mail. Specify users email here and subject.
//SendMail can have a third parementer for message if you do not wish to build a template.

if(!$mail->sendMail($this->clean_email,"New User"))
{
$this->mail_failure = true;
}
}
$this->success = lang("ACCOUNT_REGISTRATION_COMPLETE_TYPE2");
}
else
{
//Instant account activation
$this->user_active = 1;
$this->success = lang("ACCOUNT_REGISTRATION_COMPLETE_TYPE1");
}if(!$this->mail_failure)
{//Insert the user into the database providing no errors have been found.
$stmt = $mysqli->prepare("INSERT INTO ".$db_table_prefix."users (
user_name,
display_name,
password,

mobile1,
activation_token,

VALUES (

$stmt->bind_param("sssssi", $this->username, $this->displayname, $secure_pass, $this->clean_email, $this->mobile1, $this->activation_token, $this->user_active);
$stmt->execute();
$inserted_id = $mysqli->insert_id;
$stmt->close();

//Insert default permission into matches table
$stmt = $mysqli->prepare("INSERT INTO ".$db_table_prefix."user_permission_matches  (

permission_id
)
VALUES (

'1'
)");
$stmt->bind_param("s", $inserted_id);
$stmt->execute();
$stmt->close();

}
}
}
}
