Hello,

I am trying to ckeck if the username is already tacken.

1.   rules: {
          username: {
             required: true,
             maxlength: 20,
             remote: {
           url: "verifusername.php",
           type: "post",
             },
   
   
   
   
   
   
   

verifusername.php file:

1. $file = ''.$_SERVER["DOCUMENT_ROOT"].'/dbconnect.php';
   if (file_exists($file)) include($file);
   
   if(isset($_POST['username']))
   {
   $user = ucfirst(strtolower(trim(htmlspecialchars(mysql_real_escape_string($_POST['username'])))));
   
   // VERIFICATION
   $result = mysql_query('SELECT user FROM members WHERE user="'.$user.'"');
   
   if(mysql_num_rows($result)>=1)
           {
           return TRUE;
           }
   else
           {
           return FALSE;
           }
   
   }
   else
   {
   return FALSE;
   }
   mysql_free_result($result);
   mysql_close($db);
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   

The problem is that the script always return that username already in use...

Why?

Thx
