Question

I am developing an application using symfony2. I would like to know how I can receive arguments from a template in a controller because I want to store the value of the argument in the data base. The argument will get its value in a JavaScript script inside the template and must be passed to the controller when submitting a button. This is the script:

$("MatchedTag").click(function () 
 {
       $(this).toggleClass("highlight");

       var IdOfTag = this.id;  

 }); 

The variable I want to receive in the controller is IdOfTag. How can I do this? Thanks.

You can pass the variable using AJAX (take a look at $.ajax, $.post, $.get – jQuery) or add a hidden input field to form with the desired value.

Example

If you want to pass IdOfTag to /path/controller/tags (as example) using jQuery.ajax your code will looks like this:

$("MatchedTag").click(function () 
 {
       $(this).toggleClass("highlight");

       var IdOfTag = this.id;  
       $.ajax({
          url: "/path/controller/tags",
          type: "POST",
          data: { "tag_id" : idOfTag },
          success: function(data) {
             //(success) do something...
             //variable "data" contains data returned by the controller. 
          }
       });
});

Then in the controller you can get the value of idOfTag through $_POST["tag_id"]
