How to pass default parameters to laravel controller in a get route
提问by horse
I have a route like that:
我有一条这样的路线：
Route::get('category/{id}/{date?}', array('as' => 'category/date', 'uses' => 'Controller@getCategory'));
I want to run @getCategory with default parameters when called '/' root route. So if '/' route called, getCategory function should run with id=1 and date=2015-12-18.
我想在调用“/”根路由时使用默认参数运行 @getCategory。因此，如果调用“/”路由，则 getCategory 函数应以 id=1 和 date=2015-12-18 运行。
How should I do that?
我该怎么做？
回答by Joseph Silber
Register it as a separate route:
将其注册为单独的路由：
Route::get('/', 'Controller@getCategory')->named('home');
Route::get('category/{id}/{date?}', 'Controller@getCategory')->named('category/date');
Then in your controller, set default values for those arguments:
然后在您的控制器中，为这些参数设置默认值：
public function getCategory($id = 1, $date = '2015-12-18')
{
// do your magic...
}

It works for me with a "?" {date?}in the route, and putting a default value in the anonimus function.$date = null
它适用于我"?" {date?}在路线中使用 a并在anonimus 函数中放置一个默认值。$date = null
Route
路线
Route::get('category/{id}/{date?}', function($date = null) {
if ($date === null)
//Option 1
else
//Option 2
});
