Send data to controller via Ajax

I am new to Ajax and I am using Laravel, now I want to have a delete button that will send the id of the item that I want to delete to controller. Here is my code:

Views

      <div class="row">
        @foreach($photos as $photo)
     <div class="col-xs-3 col-md-1">
    <button onclick="removeItem({{$photo->id}}); return false;">Delete</button>   
          </div> 
          @endforeach

        </div>

Here is my script for now, I don't have an idea on this:

     <script type="text/javascript">
    function removeItem($myvar) {
        alert($myvar);
    }
    </script>

I want to send this to this route:

       Route::post('deletephoto','GamefarmsController@deletephoto');

You need to perform an XMLHTTPRequest to the server via AJAX. Since you are using a jQuery as javascript library, such request is easy using functions like post or ajax.

your HTML/template:

<button class="my_button" id="{{$photo->id}}" data-url="{{path('deletephoto')}}">Delete</button>

So, inside your javascript function, use something like:

function removeItem() {

     $('button.my_button').click(function(e){
            e.preventDefault();     
            var url = $(this).attr('data-url');
        var id = $(this).attr('id');
        $.ajax({
                            type: "POST",
                            url: url,
                            data: {id:id},
                            cache: false,
                            success: function(data){

                            }
                            });

        return false;
       });

    }

In details: We add a data attribute to your HTML button that would contain your path, If you are using Twig as templating engine, you can write something like:

data-url={{path('path_delete')}}

But it depends on your template engine and laravel way of routing.

Then using the attr() jQuery function onclick on your button:

var url = $(this).attr('data-url');

You can apply the same rule to get your id.

Finally, you should write a controller that will get the POST request with the id parameter and perform deletion. You can get your id from the request object inside controller, something like:

if($request->isXmlHttpRequest())
      {
$id = (int)$request->request->get('id');

}
