所以基本上我只想要下面这段代码:
//basic email validation
if(!eregi('^x[\d]{8}@student\.ncirl\.ie$', $email)){
// Return Error - Invalid Email
$error = true;
$emailError = 'The email you have entered is invalid, please try again.';
}
if ( !filter_var($email,FILTER_VALIDATE_EMAIL) ) {
$error = true;
$emailError = "Please enter valid email address.";
} else {
// check email exist or not
$query = "SELECT userEmail FROM users WHERE userEmail='$email'";
$result = mysql_query($query);
$count = mysql_num_rows($result);
if($count!=0){
$error = true;
$emailError = "Provided Email is already in use.";
}
}
验证电子邮件是否与电子邮件完全相似 - " x14332684@student.ncirl.ie" ,我希望它保持x在开始,在x之后有8个随机数,因为它是@之后的所有内容。只有数字是随机的,其余的应该是"必须"。我不能让它像我想要的那样验证电子邮件,使用此代码告诉我pernament"您输入的电子邮件无效,请再试一次。"。谁能为我编辑代码并指出我在做错了什么?谢谢。

这适用于preg_match。您需要做的一件事是使用分隔符包装模式,大多数使用/
,如:
if(!preg_match('/^x[\d]{8}@student\.ncirl\.ie$/', $email)){
// Return Error - Invalid Email
$error = true;
$emailError = 'The email you have entered is invalid, please try again.';
}
