Checking username availability with ajax using jQuery

Question

I try to use the next example to checking username availability but I can't receive the result of .post that I want.

http://web.enavu.com/tutorials/checking-username-availability-with-ajax-using-jquery/

In the next code, the alert() show me the .php file, but I just want 0 or 1 in order to know if the user exist or not:

    //use ajax to run the check
    $.post("check_username.php", { username: username },
        function(result){ alert(result);
            //if the result is 1
            if(result == 1){
                //show that the username is available
                $('#username_availability_result').html(username + ' is Available');
            }else{
                //show that the username is NOT available
                $('#username_availability_result').html(username + ' is not Available');
            }
    });

Thanks a lot!

after var username = $('#username').val(); alert(username) and check what is the value you are sending. Also what is the alert you get after the post ? — sreeprasad

Where are you hosting your php file? Inside apache? If you are getting the full contents of php file then most probably you have not deployed it correctly.

I'm using in localhost a WampServer. What is your advice? :)

Try to call the php file using your browser's address and see what is being returned. For example localhost/MYAPPNAME/check_username.php if you are still getting contents of the file then it is really a server issue.

@Shamaila Tahir I didn't put the file in the good place for apache. Now I have a sql error, thanks, I try to fix it.
