i try display error message when email used jquery validation. unfortunately there no error message, when email used. tried following:

javascript

$('#registerform').validate({     rules: {         registeremail: {             required: true,             remote: 'ajax/ajax.validateemail.php'         }     },     messages: {         registeremail: {            remote: 'e-mail taken'         }     } }); 

php

<?php header('content-type: application/json');  $stmt = $mysqli->prepare("select * members m memail = ? limit 1"); $stmt->bind_param('s', $_post['registeremail']); $stmt->execute(); $stmt->store_result(); $stmt->fetch();  if ($stmt->num_rows == 1) {     echo false; }else{     echo true; } 

what doing wrong here? in advance help!

you need echo return true or false in backend php file.

instead of

echo(json_encode(false)); 

change

echo 'false'; 

same true

example

explanation:

jquery remote method required output either true or false remote url.

if echo true there, jquery consider boolen true

and if echo false, jquery convert boolean false.
