Pass multiple values of a HTTP request parameter

Question

How to pass multiple values of a single HTTP request parameter, and retrieve them in the controller?

Whether it be a repeated parameter like so:

http://example.com/users?q=1&q=2

or multiple values in a row like that:

http://example.com/users?q=1,2

Thank you for your help.

See by yourself, I saw nothing about multiple values parameters laravel.com/docs/5.6/requests#retrieving-input — JacopoStanchi

Just grab them from the $_GET array (in the controller) provided that your route is example.com/users — CSSBurner

I'm not sure about the first one, but the second approach gives you a string that you can split in your controller — Hassan Pezeshk

You can pass an array to the request like this:

http://example.com/users?q[]=1&q[]=2

The [] will pass the parameter as an array. Therefore, when you retrieve the q from the request:

dd(request('q'));

It will give you the following:

array:2 [▼
  0 => "1"
  1 => "2"
]

Are the [] characters 'normalized' for URL, like ? and & for example or is this just a shorthand only available for Laravel (and not for Spring, etc.)? Can I do ?q[]=1,2?

@JacopoStanchi Yes it is normalized for URL. You can do the way you suggested but it will pass a string into an array.

Just like when you pass an html input with a value of array, you can pass it with []. e.g. /users?q[]=1&q[]=2

Route::get('users', function (Illuminate\Http\Request $request) {
    // when you dump the q parameter, you'll get:
    dd($request->q);
    // q = [1, 2]
});
