Question

I think I’m doing this wrong for what I want returned with PHP. What I’m trying to do is check if the username is paid or not via ajax.

The PHP, which works by itself if I do this:

$username = $_POST['username']; 

     function checkPlayer($player) {
        $mcURL = 'http://www.minecraft.net/haspaid.jsp?user=';
        $auth = file_get_contents($mcURL . $player);

        if (trim($auth) == "true") {
          echo $player. ' is ';
        } else {
          echo $player. ' is ';
        }

        return $auth;
      }

      echo checkPlayer($username);

Does what I want if I change $username value to something static, like $username = "Notch";. But not if I use $_POST['username'], and use the following JS:

$(document).on('keyup', 'input', function(){

        var inputVal = $('input').val();
        $.post('auth.php', inputVal, function(data){
          console.log(input.Val + ' is ' data);
        });
      });

Which should print out in console if I typed in ‘Notch’, true, if something else like ‘fslfjslkfjls’ should be false.
HTML:

<form>
    <input type="text" name="username" value="" class="authcheck">
  </form>

What do I have wrong?

UPDATE: After galchen’s answer, it (kinda) works now (doesn’t give an error)

var inputVal = $('input').val();
        $.post('auth.php', { 'username' : inputVal }, function(data){
            console.log(inputVal + ' is ' + data);
        });

But now everything that inputs returns true, even if it’s not true. How can I fix this?

try:

$.post('auth.php', { 'username' : inputVal }, function(data){
    console.log(input.Val + ' is ' data);
});

you need to send the object in the ajax – it’s a dictionary of the request variables
