Check if parameter is used in url laravel-CodePudding

I'm trying to check if a parameter name is included in a specific url like this: http://127.0.0.1:8000/box?size[eq]=200

I want to retrieve the name "size[eq]" in my laravel controller but it keeps returning false.

This is the code I'm using:

public function index(Request $request)
    {
 
      dd($request->has("size[eq]"));
    
     }

CodePudding user response：

That is an array named size with an index named eq. It isn't an actual string on the server side. Most of Laravel's functions use the "dot notation" for dealing with nested elements. So for what would be $requestData['size']['eq'] would be:

$request->has('size.eq');

If you want to retrieve that value you would also use "dot notation":

$request->input('size.eq');
