好的。所以这是我下面的代码。我正在尝试遵循有关验证电子邮件的 webtuts 教程。但我的样本没有成功。它应该提醒用户它输入了无效的电子邮件。所以我的伙伴所做的是他创建了“show_warning”jquery 函数来允许我显示我的 $msg。但它不起作用。我的逻辑错了吗?
<?php
if(isset($_POST['username']) && !empty($_POST['username']) AND
isset($_POST['password']) && !empty($_POST['password']) AND
isset($_POST['email']) && !empty($_POST['email']) AND
isset($_POST['role_id']) && !empty($_POST['role_id']))
{
$username = ($_POST['username']);
$password = ($_POST['password']);
$email = ($_POST['email']);
$role_id = ($_POST['role_id']);
if(!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email))
{
$msg = 'The email you entered is invalid. Please try again.';
}
else
{
$msg = 'Your account has been made, <br /> please verify by clicking the activation link in your email.';
}
}
?>
