JQuery AJAX returns error 500 despite successful server-side execution

I ran into a problem with codeigniter and jQuery Ajax Post.

My javscript

        $('.remove').click(function(){
        var category=event.target.id;
        var id=$('input[name=article_id]').val();
        var p={};
        p['id']=id;

        $.ajax({
            type: "POST",
            url: "/backend.php/blog/removeCategories",
            async:true,
            cache:false,
            data: {id: id, category: category }
            }).done(function(msg){
                jQuery('#category_list').load('/backend.php/blog/refreshCategories/',p,function(str){});
            });

My codeigniter controller

 function removeCategories(){
        $id=$_POST['id'];
        $category_id=$_POST['category'];

        $this->article->removeCategory($category_id,$id);
    }

I can not get the ajax function to work, because there is always a 500 error received from the server. Although firebug returns that there was an error loading resources, the removeCategories function was executed anyway.

Your mistake may be in the model. Use the chrome dev toolkit to find out what the content of the returned page is. HTTP CODE 500means a server error, usually due to a syntax problem inside PHP.

, - success: error:. , .

backend.php/ index.php?

- .load() html , success: function(data){} . , ajax error() success() .

, , data.

$.ajax({
            type: "POST",
            url: "/backend.php/blog/removeCategories",
            async:true,
            cache:false,
            data: {"id": id, "category": category }
            }).done(function(msg){
                jQuery('#category_list').load('/backend.php/blog/refreshCategories/',p,function(str){});
            });

Codeigniter, csrf_protection config, Error 500!

, csrf.

:

$.ajax({
          type: "POST",
          url: "http://example.com",
          data: {
                 '<?php echo $this->security->get_csrf_token_name(); ?>' : 
                 '<?php echo $this->security->get_csrf_hash(); ?>'
                }
       });
