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 https://laravel.com/docs/5.6/requests#retrieving-input — JacopoStanchi, Jun 12 '18 at 15:00
Just grab them from the $_GET array (in the controller) provided that your route is http://example.com/users — CSSBurner, Jun 12 '18 at 15:01
I'm not sure about the first one, but the second approach gives you a string that you can split in your controller — Hassan Pezeshk, Jun 12 '18 at 15:01
@LeszekRepie You're conflating passing two different parameters and passing one parameter with several values. — JacopoStanchi, Jun 12 '18 at 15:08
@JacopoStanchi: use comma and then split into array? or array https://stackoverflow.com/questions/5098397/how-to-pass-an-array-in-get-in-php?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa — Leszek P, Jun 12 '18 at 15:17
I wondered if it was implemented by Laravel, if I have to do `$list = explode(',',$req->q);` then the answer is no. — JacopoStanchi, Jun 12 '18 at 15:19

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 Jun 12 '18 at 16:06

@JacopoStanchi Yes it is normalized for URL. You can do the way you suggested but it will pass a string into an array. – Chin Leung Jun 12 '18 at 16:15

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]
});
