$( "#myform" ).validate({
rules: {
email: {
required: true,
email: true,
remote: {
url: "check-email.php",
type: "post",
data: {
email: function() {
return $( "#email" ).val();
}
}
}
}
}
});
/*************** check-email.php **************/
< ?php
/* check if email is already registered */
//connect to db using mysqli
if (!empty($_POST['email']))
{
$email = $mysqli->real_escape_string($_POST['email']);
$query = "SELECT ID FROM users WHERE user_email = '{$email}' LIMIT 1;";
$results = $mysqli->query($query);
if($results->num_rows == 0)
{
echo "true"; //good to register
}
else
{
echo "false"; //already registered
}
}
else
{
echo "false"; //invalid post var
}
?>
