Ajax request return empty array

Question

I am trying to get the id, where the user clicked, and pass it to my controller via AJAX. For some reason, when i try to show what i am receiving in my controller, it show an empty array.

Any idea why my alert return an empty Array?

JS Function:

function categorySelected(elem) {
 $.ajax({
 url: "/newgallery/creative-fields-click",
 type: "POST",
 data: elem.id
 }).done(function (response) {
 alert(response);
 });
}

PHP:

public function creativeFieldsClickAction()
{
 $idSelected = $this->_request->getPost();
 print_r( $idSelected );
 exit();
}

• codea: Have you tried to use a client like SOAP UI to query the web service and see what it returns?

Answer 1

Data should be JSON, not integer.

data: { elemid : elem.id }

Then in PHP data can be found from $_POST['elemid']. In your code it could be like

$this->_request->getPost()['elemid'];

Or something like that.

Answer 2

Try by changing

In ajax

data: { id : elem.id }

And in action of controller

$ids = $_POST;
print_r($ids);
