Laravel Csrf Token Mismatch For Ajax Post Request

Laravel csrf token mismatch for ajax POST Request

You have to add data in your ajax request. I hope so it will be work.

data: {
        "_token": "{{ csrf_token() }}",
        "id": id
        }

Ajax Post to Laravel - CSRF Token Mismatch

I had the same problem
try to put include CSRF tag in your meta like so

<meta name="csrf-token" content="{{ csrf_token() }}" />

and read it in your ajax code like so :

<script type="text/javascript">
$.ajaxSetup({
    headers: {
        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
    }
});
</script>

Last Update

Please modify your url variable like so :

jQuery.ajax({
    type: "POST",
    url: '/my-route'+'?_token=' + '{{ csrf_token() }}',
    data: data,
    success: function() {
         console.log("A");
    }
  });

Getting Error: CSRF token mismatch in laravel 8

You need to send the csrf token on header, not with the form data. try something like this on your code:

To add a default header with every request, use $.ajaxSetup():

 $.ajaxSetup({
            headers: {
                'X-CSRF-Token': $('meta[name="csrf-token"]').attr('content')
            }
        });

or else you can add the header like below code:

$.ajax({
                        url: url,
                        headers: { 'X-CSRF-Token': ('meta[name="csrf-token"]').attr('content') }
                        type: 'PATCH',
                        data: new FormData($("#formId")[0]),
                        cache : false,
                        processData: false,
                        contentType: false,
                        success: function (res){
                            console.log(res);
                        }
                        ,error: function (err){
                            console.log(err);
                        }
                    });

Regenerate CSRF Token If ajax request has an error

Remove headers from $.ajaxSetup and put it in send_form request like this.

$('#send_form').html('Sending..');
        /* Submit form data using ajax*/
        $.ajax({
            url: "{{ route('register')}}",
            method: 'POST',
            headers: {
             'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
            },
            data: $('#ajax-register-form').serialize(),

            success: function(response) {


            $('#send_form').html('Submit');

            document.getElementById("ajax-register-form").reset();


              },
            error: function(data) {
              var errors = data.responseJSON;
              console.log(errors);
              $('.error-warning').show();

              }
        });
    });
