csrf regenrate in ajax post

I have this code for post data using ajax:

Code:

        $("selector").select2({
            minimumInputLength: 3,
            theme: 'bootstrap4',
            width: 'auto',
            ajax: {
                url: "<?= route_to('autocomplete'); ?>",
                type: "post",
                dataType: 'json',
                delay: 250,
                data: function(params) {
                    return {
                        searchTerm: params.term,
                        csrf_token: csrf_token // token get from js var
                    };
                },
                processResults: function(response) {
                    return {
                        results: response
                    };
                },
                cache: true
            }
        });

if I enable token regenerate, my code work only for first post data.

I not found best practice for fix csrf token regenerate in multiple ajax post. any one can help!?

Why not the filter to tell card to ignore the actual controller and do some checking in the controller by checking if the actual post I ajax request

Sorry but whats your mean ?!

Read this.

I read it before, this is not clear way for add token in each ajax json response controller. i think codeigniter need to laravel solution like this

Maybe something like this, not tested.

Code:

$(function($) {

    // this script needs to be loaded on every page where an ajax POST may happen

    $.ajaxSetup({
        data: {
            // you would need to load the Security Lib in the Controller.
            '<?php echo $security->getCSRFTokenName(); ?>' :
            '<?php echo $security>getCSRFHhash();?>'
        }
    });

    // now write your ajax script

});

Not sure if the view would see the security lib from the controller.

I'll play around with this later on.
