laravel - Request::has() returns false even when parameter is present

Question

URL: http://localhost/?v=

Code:

Route::get('/', ['as' => 'home', function()
{
    dd(Request::has('v'));
}]);

Output: false

What is going on? Is this a bug or am I doing something wrong?

Answer 1

Request::has() will check if the item is actually set. An empty string doesn't count here.

What you are looking for instead is: Request::exists()!

Route::get('/', ['as' => 'home', function()
{
    dd(Request::exists('v'));
}]);
