Ajax Request

[eluser]Nutan Lade[/eluser]
I tried both the cases.i.e upper and lower case.
still the same error

A PHP Error was encountered

Severity: Notice

Message: Use of undefined constant userId - assumed 'userId'

when using this code it was returing array(0){}

Code:

var_dump($_POST); exit;

Code:

function submitMovie(movieId){
  //    alert(movieId);
    var url = "<?=base_url()?>index.php/gadgets/addMovie/"+movieId;
        
        var msgBox = "movieLink_"+movieLink;

        new Ajax.Request(url, {
        method: 'post',
        parameters: {userId: 1},
        onComplete: function(addmovie){
          var response = addmovie.responseText || "no response text";
          document.getElementById(msgBox)[removed] = response;        
        },
        onFailure: function(){ alert('Something went wrong...') }
          });
  }

and the server code is

Code:

function addMovie(){
        echo "hi";        
        var_dump($_POST); exit;
        //echo $_POST[userId];
        
    }

it was returning hi and array(0){}
