Question

我做了一个注册表，但我有一个问题。 email_exist函数不起作用，它不会检查该电子邮件是否已存在于数据库中且没有错误。

有人能帮助我吗？

由于

这是我的代码： PHP代码：

    function sanitize ($data1){
        return htmlentities(strip_tags(mysql_real_escape_string($data1)));
    }

    function email_exist($email){
        $email = sanitize($email);
        return (mysql_result(mysql_query("SELECT COUNT(`id`) FROM `companys` WHERE `email` = '$email'"), 0) === 1) ? true : false;
    }

    function output_errors($errors){
        return '<ul class="err_ul"><li>'.implode('</li><li>',$errors).'</li></ul>';
    }

    function array_sanitize(&$item){
        $item = htmlentities(strip_tags(mysql_real_escape_string($item)));
    }

    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 `companys` ($fields) VALUES ($data)");

        require_once 'swiftmailer/lib/swift_required.php';

        $transport = Swift_SmtpTransport::newInstance('smtp.gmail.com', 465, "ssl")
            ->setUsername('')
            ->setPassword('');

        $mailer = Swift_Mailer::newInstance($transport);

        $message = Swift_Message::newInstance('Aktivacija korisničkog računa')
            ->setFrom(array(''))
            ->setTo(array($register_data['email']))
            ->setBody("Zdravo".$register_data['name'].",\n\n da bi aktivirao svoj korisnički račun odi na dolje navedeni link:\n\n http://localhost/croglas/activate.php?email=".$register_data['email']."&email_code=".$register_data['email_code']."\n\n crOglas");

        $result = $mailer->send($message);  
    }

    if(empty($_POST) === false){

                break 1;
            }
        }
        if(empty($errors) === true){
            if(strlen($_POST['password']) < 4){
                $errors[] = 'Lozinka mora sadržavati više od 4 znaka';

问题已解决

if(email_exist($_POST['email']) === true){
                $errors[] = 'Ta email adresa je već u uporabi';
}

替换为

if(email_exist($_POST['email']) == true){
                $errors[] = 'Ta email adresa je već u uporabi';
}
