Vous pouvez utiliser la méthode à distance à la place qui vous permet de faire des vérifications à distance : http://docs.jquery.com/Plugins/Validation/Methods/remote
Par exemple.
$("#yourFormId").validate({
rules: {
email: {
required: true,
email: true,
remote: {
url: "checkUnameEmail.php",
type: "post"
}
}
},
messages: {
email: {
required: "Please Enter Email!",
email: "This is not a valid email!",
remote: "Email already in use!"
}
}
});
checkUnameEmail.php //Ex.
<?php
$registeredEmail = array('[email protected]', '[email protected]', '[email protected]', '[email protected]', '[email protected]');
$requestedEmail = $_REQUEST['email'];
if( in_array($requestedEmail, $registeredEmail) ){
echo 'false';
}
else{
echo 'true';
}
?>
