How to pass yii2 search params through javascript api call

Question

my search params is

$params=Yii::$app->request->queryParams;

And my api call is like

function doInBackground(){
      var params=<?=json_encode($params)?>;
       $.get('car/get-map-data',
          {
           "params":params
      },
      function(data){
        if(data)
        {
          console.log(data);
        }
      }); 
    }

But i am getting an error like

PHP Notice – yii\base\ErrorException
Array to string conversion

on the line

var params=<?=json_encode($params)?>;

How to solve this.I want to pass the search params to another api.

Answer 1

you can use getQueryString()

function doInBackground(){
  var params=<?=Yii::$app->request->getQueryString();?>;
   $.get('car/get-map-data',
      {
       "params":params
  },
  function(data){
    if(data)
    {
      console.log(data);
    }
  }); 
}

Answer 2

I think that handling the query params via URLSearchParams would be more non-hacky and clearer solution than obtaining them via PHP.

By URLSearchParams you can collect them into JS object and properly pass it as POST data to your AJAX request.
