function validateName($name){
//if it's NOT valid
if(strlen($name) return false;
//if it's valid
else
return true;
}
function validateEmail($email){
return ereg("^[a-zA-Z0-9]+[a-zA-Z0-9_-]+@[a-zA-Z0-9]+[a-zA-Z0-9.-]+[a-zA-Z0-9]+.[a-z]{2,4}$", $email);
}
function validatePasswords($pass1, $pass2) {
//if DOESN'T MATCH
if(strpos($pass1, ' ') !== false)
return false;
//if are valid
return $pass1 == $pass2 && strlen($pass1) > 5;
}
function validateMessage($message){
//if it's NOT valid
if(strlen($message) return false;
//if it's valid
else
return true;
}
?>
复制代码 代码如下:
- Invalid Name: We want names with more than 3 letters!
- Invalid E-mail: Stop cowboy! Type a valid e-mail please :P
- Passwords are invalid: Passwords doesn't match or are invalid!
- Ivalid message: Type a message with at least with 10 letters
- Congratulations! All fields are OK ;)
