Checking if a request array is empty in Laravel

Question

I have a dynamically generated form that gives me an array of inputs. However the array might be empty, then the foreach will fail.

    public function myfunction(Request $request)
    {
    if(isset($request))
     {
       #do something
     }

    }

This obviously doesn't work since it is a $request object and is always set. I have no idea however how to check if there is any input at all.

Any ideas?

Answer 1

A simple count check will do

if (count($request->all())) {
  // foreach here.
}

Answer 2

I always do this with my installations by adding a function to the Controller in the App\Http\Controllers directory.

use Illuminate\Http\Request;
public function hasInput(Request $request)
{
    if($request->has('_token')) {
        return count($request->all()) > 1;
    } else {
        return count($request->all()) > 0;
    }
}

Rather self explanatory, return true if other input variables outside of the _token, or return true if no token and contains other variables.
