Add export CSV with post as a method.

[jiwom]

Use postCsv as button. This button is recommended for IE browsers since IE has URL length limit.

Example Snippet

public function html()
{
    return $this->builder()
        ->columns($this->getColumns())
        ->parameters([
                'buttons' => ['postCsv'],
        ]);
}

Take note of adding CSRF token

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

</script>

Take note of your Routing

$router->post('sample/export', SampleController::class . '@index');

Can you please provide a complete snippet on how to use this including the routes?

[yajra]

I think this csrf token will not work since you are using a native ajax call.

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

Thanks! Done! I have change the parameter token variable to $('meta[name="csrf-token"]').attr('content');

Implementing Notes

• Make sure you have meta header for the token on your template

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

• You need to add additional routes that will handle the export process but points to same method with the main dataTable get route.

Route::get('users', UsersController::class.'@index');
Route::post('users/export', UsersController::class.'@index');

• Replce csv with postCsv on your buttons array.
