fieldset, label { margin: 0; padding: 0; } body{ margin: 20px; } h1 { font-size: 1.5em; margin: 10px; }  .rating {     border: none;     float: left; }  .rating > input { display: none; } .rating > label:before {     margin: 5px;     font-size: 1.25em;     font-family: fontawesome;     display: inline-block;     content: "\f005"; }  .rating > .half:before {     content: "\f089";     position: absolute; }  .rating > label {     color: #ddd;     float: right; }  .rating > input:checked ~ label, .rating:not(:checked) > label:hover, .rating:not(:checked) > label:hover ~ label { color: #ffd700;  }  .rating > input:checked + label:hover, .rating > input:checked ~ label:hover, .rating > label:hover ~ input:checked ~ label, .rating > input:checked ~ label:hover ~ label { color: #ffed85;  }

in view test.html.twig:

<html> <head>     <link rel="stylesheet" href="{{ asset('bundles/hearwegohearwego/css/rating.css') }}" />     <script src="{{ asset('bundles/hearwegohearwego/js/jquery.min.js') }}"></script>     <script>         $(function () {             $("#demo1 .stars").click(function () {                 var id=$(this).attr('id');                 $.ajax({                     url: "{{ path('test') }}",                     type: 'post',                     data: {id1:id},                     success: function(result)                     {                         alert(id);                     }                 });             });         });     </script> </head> <body> <fieldset id='demo1' class="rating">     <input class="stars" type="radio" id="star5" name="rating" value="5" />     <label class = "full" for="star5" title="awesome - 5 stars"></label>     <input class="stars" type="radio" id="star4" name="rating" value="4" />     <label class = "full" for="star4" title="pretty - 4 stars"></label>     <input class="stars" type="radio" id="star3" name="rating" value="3" />     <label class = "full" for="star3" title="meh - 3 stars"></label>     <input class="stars" type="radio" id="star2" name="rating" value="2" />     <label class = "full" for="star2" title="kinda bad - 2 stars"></label>     <input class="stars" type="radio" id="star1" name="rating" value="1" />     <label class = "full" for="star1" title="sucks big time - 1 star"></label> </fieldset> </body> </html>

in defaultcontroller.php (in right folder declared in test.html.twig script):

/**      * @route("/test", name="test")      */     public function testaction(request $request)     {         if($request->isxmlhttprequest()) {             $b=$request->get('id1');             echo $b;         }         return $this->render('hearwegohearwegobundle::test.html.twig');     }

                success: function (result)                 {                     alert(result)                     console.log(result)                 }

and in controller:

public function testaction(request $request)     { //        print_r($request);         if($request->isxmlhttprequest()) {             $b=$request->request->get('id1');             echo $b;         }         return new \symfony\component\httpfoundation\response();     }
