Laravel routing: how to pass parameter to controller (not via URL)?
提问by Andrew Vershinin
I have two routes: A/{param}/Cand B/{param}/C. Also I have a controller with method:
我有两条路线：A/{param}/C和B/{param}/C。我还有一个带有方法的控制器：
public function index($param, $param1 = false)
{
//...
}
In case of A/{param}/CI pass only one parameter - one specified in URL, and the function uses the default for second one. In case of the second route, I want to pass trueas second parameter. Since it isn't specified in URL, how to pass it to the function?
如果A/{param}/C我只传递一个参数 - 在 URL 中指定的一个，并且该函数使用第二个的默认值。在第二条路线的情况下，我想true作为第二个参数传递。由于没有在 URL 中指定，如何将其传递给函数？

If i understand you correctly, without using $_POST, you won't be able to pass a parameter without be being somewhere in the URI (outside of setting a session variable, which i wouldn't advise)
如果我理解正确，如果不使用 $_POST，您将无法传递参数而不位于 URI 中的某处（设置会话变量之外，我不建议这样做）
Another option may be to pass it as a query string parameter. It will still be in the url, but won't necessarily be caught in the route pattern
另一种选择可能是将其作为查询字符串参数传递。它仍然会在 url 中，但不一定会被捕获在路由模式中
URLs:
网址：
A/{param}/C
B/{param}/C?param1=true
--
Controller:
--
控制器：
public function index($param)
{
$param1 = Request::query('param1'); // if not present false, if present, {value}
}
--

Alternatively, if you'd like a friendly URL, you can place a question mark after your second parameter, indicating that it may or may not exist. This will match both of the below URLs
或者，如果您想要一个友好的 URL，您可以在第二个参数后放置一个问号，表明它可能存在也可能不存在。这将匹配以下两个 URL
URL:
网址：
A/{param}/C
B/{param}/C/true
Route:
路线：
Route::get('B/{param}/C/{param1?}', 'YourController@index');
Controller:
控制器：
public function index($param, $param1 = false)
{
//
}
