Question

I am trying to get ajax working with a codeigniter installation.

This is my PHP function:

    function test() {
            return print_r("hey");
    }

This is the JS:

    $.ajax({
          type: "POST",
            url: "http://localhost/code/test",
            success: function(data) {
                    alert(data);    
            }
    });

This works perfectly but, as soon as I add data it doesn’t work.

    $.ajax({
          type: "POST",
            url: "http://localhost/code/test",
            data: {bar:"foo"}, 
            success: function(data) {
                    alert(data);    
            }
    });

Thanks in advance!

Answer 1

please check the following

$.ajax({
          type: "POST",
            url: "http://localhost/code/test",
            data: "&bar=foo&isAjax="+true, 
            success: function(data) {
                    alert(data);    
            }
    });

And controller…

function test() {
            if($this->input->post('isAjax')){
                  return print_r("hey");
            }
            else{
                  //do another thing
            }

    }

And another thing if you want to add data in json format then you have to add another property in your $.ajax object that is datatype: "json"
