单击电子邮件激活链接后，php和mysql未激活新用户[关闭]

i am creating a registration/login system with php. my code is able to send an activation link to the new user via email, but wen user clicks on the link, user is not activated..pls can anyone help, the codes are below...

users.php

function activate($email, $email_code) {
    $email          = mysql_real_escape_string($email);
    $email_code     = mysql_real_escape_string($email_code);

    if (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `user` WHERE `email` = '$email' AND `email_code` = '$emal_code' AND `active` = 0"), 0) == 1) {
        if (mysql_query("UPDATE `user` SET `active` = 1 WHERE `email` = '$email'")){
         return true; 
    } else {
         return false;  
    }

}
}

function register_user ($register_data) {
    array_walk($register_data, 'array_sanitize');
    $register_data['password'] = md5($register_data['password']);

    $fields = '`' . implode('`, `', array_keys ($register_data)) . '`';
    $data   = '\'' . implode('\', \'', $register_data) . '\'';

    mysql_query("INSERT INTO `user` ($fields) VALUES ($data)");
    email($register_data['email'], 'Activate your account', "Hello " .      $register_data['username'] . ",

You need to activate your account by clicking the link below:

http://fredhosting.com/real/activate.php?email=" . $register_data['email'] . "&email_code=" . $register_data['email_code'] . "

 - Fredhosting.com");
}

Activate.php

if (isset($_GET['success']) === true && empty($_GET['success']) === true) {
?>
    <h2>Thanks, we have activated your account...</h2>
    <p>You can now Log in!</p>
<?php
} else if (isset($_GET['email'], $_GET['email_code']) === true) {

    $email       = trim($_GET['email']);
    $email_code  = trim($_GET['email_code']);

    if (email_exists($email) === false) {
        $errors[] = 'Oops, something went wrong and we could not find that email address.';
    } else if (activate($email, $email_code) === false) {
        $errors[] = 'We had some issues activating your account.';
    }

    if (empty($errors) === false) {
    ?>
        <h2>Oops...</h2>
    <?php
        echo output_errors($errors);
    } else {
        header('Location: activate.php?success');
        exit(); 
    }

}

Error:

if (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM 
`user` WHERE `email` = '$email' 
AND `email_code` = '$emal_code' 
AND `active` = 0"), 0) == 1)

incorrect variable $emal_code

Spelling errors are normally, however, before you post your code reread several times!

It seems that you are working with PHP errors turned off, activate recommend them.

ini_set('display_errors', '1');
error_reporting(E_ALL);
