Answer 1

Short and Simple Solution

e.preventDefault();
var value = $('#id').val();
var id = $('#some_id').val();
url="{{url('office/service/requirement/rule_delete/')}}" +"/"+ id;
console.log(url);
$.ajaxSetup({
    headers: {
        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
    }
});
$.ajax({
/* the route pointing to the post function */
    url: url,
    type: 'DELETE',
/* send the csrf-token and the input to the controller */
    data: {message:value},
    dataType: 'JSON',
/* remind that 'data' is the response of the AjaxController */
    success: function (data) { 
    console.log(data)
    //$('.writeinfo').append(data.msg);
    //$('#ruleRow'+id).remove();
    }
});
return false;

Answer 2

90% of the laravel ajax internal server error is due to missing CSRF token. other reasons can inlucde:

• Wrong Request Type (e.g sending post to get)
• Wrong data type recived (e.g ajax is expecting JSON and app returns string)
• Your .htaccess is misconfigured
• Missing Route
• Code Error

I guess this has been solved by now but still the best thing to do here is to send the token with your form

{!! csrf_field() !!}

and then in your ajax

$("#try").click(function(){
var url = $(this).attr("data-link");
$.ajax({
    url: "test",
    type:"POST",
    data: { '_token': token, 'someOtherData': someOtherData },
    success:function(data){
        alert(data);
    },error:function(){ 
        alert("error!!!!");
    }
}); //end of ajax
});

Answer 4

By default Laravel comes with CSRF middleware.

You have 2 options:

1. Send token in you request
2. Disable CSRF middleware (not recomended): in app\Http\Kernel.php remove VerifyCsrfToken from $middleware array

Answer 5

for me this error cause of different stuff. i have two ajax call in my page. first one for save comment and another one for save like. in my routes.php i had this:

Route::post('posts/show','PostController@save_comment');
Route::post('posts/show','PostController@save_like');

and i got 500 internal server error for my save like ajax call. so i change second line http request type to PUT and error goes away. you can use PATCH too. maybe it helps.

do not forget add "use Illuminate\Http\Request;" on your controller
