php – How can I get new CSRF token in LARAVEL by using ajax

Posted by: admin July 12, 2020 Leave a comment


I have created a form which is having a lot of fields and user can create an unlimited field in it.
If a user spends more time on it CSRF token get expires and when he clicks on the submit LARAVEL return the error CSRF token mismatch.
So how can I get new CSRF token by using ajax call so I can update the CSRF on a regular time of interval?
I can not refresh or reload the form.

How to&Answers:

Just add this to your script

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

And make sure you have added token to your meta tag like below.

<meta name="_token" content="{!! csrf_token() !!}" />

I hope this will work for you.

By using this code you can get a new token after login by using the regenerate() method and returning a new csrf_token() in the response.

Your Controller inside the function:

public function refreshToken(Request $request)
     return response()->json([



    url: "{{url('refresh-token')}}",
    type: 'get',
    dataType: 'json',
    success: function (result) {
        $('meta[name="csrf-token"]').attr('content', result.token);
            headers: {
                'X-CSRF-TOKEN': result.token
    error: function (xhr, status, error) {
