Javascript message for validating username health
I'm trying to check if the register username is available, but every time the client returns his username.
This is my client code:
$(document).ready(function()
{
$("#register_username").blur(function(){
var user = $("#register_username").val();
$.post("register",
{
username: user
},
function(data, status){
if(data == '1')
{
alert('Good, username its available!');
}
else
{
alert('Snap!You cant use this username :(!');
}
});
});
});
And this is the serveride code:
if(strlen($_POST['username']) > 0)
{
$usr = $_POST['username'];
if($usr == 'test')
echo '1';
else
echo '2';
}
PHP version: 5.5

First of all, I think if the input field was "test", it would say "you cannot use this username"?
in your code if typing "test" ($usr == "test" - that comes from input)
you echo 1
, and in your code 1 means username is available ? So shouldn't it be back?
Does it say "username is available" with every input?
