php - Email-Address-Validation using jQuery Validation Plugin's remote method -


i've got problem coding email-address validation on webpage.

the first step, checking if input someone@somewhere.tld works. second check, if email exists in database, not seem work @ all.

i'm using jquery validation plugin.

this code far:

extract register.php:

<form action="addkunde.php" id="contact-form" method ="post" class="form-horizontal"> <div class="control-group">     <label class="control-label" for="email">e-mail-addresse</label>     <div class="controls">     <input type="text" class="input-xlarge" name="email" id="email">     </div> </div> <script src="js/jquery.min.js"></script> <script src="js/jquery.validate.js"></script> <script src="script.js"></script>

extract script.js:

$(document).ready(function(){     $('#contact-form').validate({     rules: {             email: {                 maxlength: 100,                 required: true,                 email: true,                 remote: {                     url : "check.php",                     type : "post"                 }             }         },         highlight: function(element) {             $(element).closest('.control-group').removeclass('success').addclass('error');         },         success: function(element) {             $(element).addclass('valid').closest('.control-group').removeclass('error').addclass('success');         }     }); });

extract check.php:

<?php include('mysql.php'); $email = trim(strtolower($_post['email'])); $email = mysqli_real_escape_string($con, $username); $result = mysqli_query($con, "select * kunde email = '$email' limit 1;"); $num = mysqli_num_rows($result); if($num == 0){     echo "true"; } else {     echo "e-mail-adresse schon registriert."; } mysqli_close($con); ?>

i've been googling hours now, following kinds of different instructions , trying implement own validation method using jquery-validation's addmethod.

i hope can me.

thanks lot!

perhaps string "e-mail-adresse schon registriert." evaluating true success check. can try changing "false" , see if makes difference?
