validation - JQuery Validator plugin: Remote call not working -


i'm trying validate user name remote validation.
here js code

$('#form_reg').validate({     rules: {      username: {         minlength: 6,         required: true,         remote: { url:"validate_usr.php", async:false }       },  }, highlight: function(element) {             $(element).closest('.control-group').removeclass('success').addclass('error');         },         success: function(element) {             element             .text('ok!').addclass('valid')             .closest('.control-group').removeclass('error').addclass('success');         }   });

and php file

<?php  include("bd_conex_mysql.php");  if (!empty($_request['username'])) { $usrname = $_request['username']; $checkname = mysqli_query("select count(*) cuentas ctausr = '".$usrname."'");   if($checkname->fetch_row() > 0){     echo 'false'; } else{     echo 'true'; } } else {  echo 'false'; }  ?>

it keeps accepting input if username taken.

i've changed php file 

    echo 'false';     ?>

and keeps validating input.

there no more support mysql_* functions, officially deprecated, no longer maintained , removed in future. should update code pdo or mysqli ensure functionality of project in future.

mysql_query returns resource rather result set. $checkname > 0 true. need fetch mysql_fetch_assoc

you should change query command mysqli_query. , check results of $checkname->fetch_row() http://us2.php.net/manual/en/mysqli.query.php
