How to setup a route for an optional second param? - happyape - 03-11-2019

Do I need to setup two rules in the Routes.php for these two urls?

Code:
1) http://mydomain.example/show-list 

2) http://mydomain.example/show-list/25

PHP Code:
Rule 1) $routes->add('show-list', 'Home::index');
Rule 2) $routes->add('show-list/(:any)', 'Home::index'); 

Is there any way to achieve that in on rule? Just trying to avoid having to repeat it.

PHP Code:
//HomeController.php 
public function index()
{
 $user_id = $this->request->uri->getSegment(2);
 if($user_id != NULL) {
 //filter data by given user_id
 } else {
 //show all data
 }
 return view('listdata', compact('data');
} 

If I have only this rule

Code:
$routes->add('show-list', 'Home::index');

then it throws 404 file not found for url http://mydomain.example/show-list/25

If I have only this rule

Code:
$routes->add('show-list/(:any)', 'Home::index');

then it throws 404 file not found for url http://mydomain.example/show-list

Have you tried:
$routes->add('show-list/(:any)', 'Home::index'/$1);

Yes I already tried and it throws up error too.

The only way I can get working is by using a regular expression with an optional flag.

Did you try it like this?

According to the doc's the $1 has to go into the quotes.

PHP Code:
$routes->add('show-list/(:any)', 'Home::index/$1');
// or
$routes->add('show-list/(.+)', 'Home::index/$1'); 

Not tested.
