Answer 1

This is sample you can modify according your need

public function actionSample()
{
if (Yii::$app->request->isAjax) {
    $data = Yii::$app->request->post();
    $searchname= explode(":", $data['searchname']);
    $searchby= explode(":", $data['searchby']);
    $searchname= $searchname[0];
    $searchby= $searchby[0];
    $search = // your logic;
    \Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;
    return [
        'search' => $search,
        'code' => 100,
    ];
  }
}

If this will success you will get data in Ajax success block. See browser console.

  $.ajax({
       url: '<?php echo Yii::$app->request->baseUrl. '/supermarkets/sample' ?>',
       type: 'post',
       data: {
                 searchname: $("#searchname").val() , 
                 searchby:$("#searchby").val() , 
                 _csrf : '<?=Yii::$app->request->getCsrfToken()?>'
             },
       success: function (data) {
          console.log(data.search);
       }
  });

Answer 2

The correct way to get the CSRF param is this:

data[yii.getCsrfParam()] = yii.getCsrfToken()

Answer 3

you have to pass _csrf tokin as a parameter

_csrf: yii.getCsrfToken()

or you can disable csrf valdation
