Laravel 9 : pass multiple optionnals parameters

Time:03-19

I am trying to create a route that takes either one of two parameters.

web.php :

Route::get('myroute/{a?}/{b?}', [MyController::class, 'testFunction'])->name('test.testFunction');

Controller:

public function testFunction( $a = null,  $b = null) {
    dd($a, $b);
    // stuff
}

Ajax call

function test($b_id) {
$url = "{{ route('test.testFunction', ':b') }}";
$url = $url.replace(":b", $b_id);
$.ajax({
  url: $url,
  type: 'GET'
})}

However the dd returns me $b_id, null instead of null, $b_id. How can I pass only b as parameter and omit a ?

CodePudding user response:

This is not really possible at the moment but there is a workaround. You can pass the parameters in an named array and change the route to simply Route::get('myroute' ...):

route('test.testFunction', ['a' => 'xyz', 'b' => 'yzt'])
===== creates
http://myroute?a=xyz&b=yzt

Afterwards you can check if the parameters a or b are present and retrieve them normally if they are.
