Getting bad request (#400) on Ajax calls using Yii 2

Question

This is my code:

$(document).on(\'change\', \'#tblhotel-int_zone_id\', function(e){
    var zoneId = $(this).val();
    var form_data = {
        zone: zoneI         


        

Answer 1

This works. Change the csrfParam with your own in Config/main.php

'components' => [
    'request'=>[
        'csrfParam'=>"othername"
    ],
    ...

Remember that you must include in your requests the token with the same name as you defined in config.

Answer 2

You need to disable CSRF validation in the before action function:

public function beforeAction($action) {
    if($action->id == "action name need to disable")
        $this->enableCsrfValidation = false;
    return parent::beforeAction($action);
}

Or using the GET method.
