Accessing route parameter in view with Laravel 4
提问by John Dorean
I have a route set up like so:
我有一个这样设置的路线：
Route::match(array('GET', 'POST'), '/reset-password/{code}', array('as' => 'reset-password-confirm', 'uses' => 'UserController@resetPasswordConfirm'));
In my controller, I'm passing the route parameter to my action like so:
在我的控制器中，我将路由参数传递给我的操作，如下所示：
public function resetPasswordConfirm($code)
{
// ...
}
I can then use $codein my controller as normal.
然后我可以$code像往常一样在我的控制器中使用。
In my view I'm building a form which POSTs to the same controller action, and I need to somehow get $codeinto the view so it constructs the proper form action. At the moment I have this:
在我看来，我正在构建一个向同一个控制器操作发送 POST 的表单，我需要以某种方式$code进入视图，以便它构建正确的表单操作。目前我有这个：
{{ Form::open(array('route' => array('reset-password-confirm'))) }}
Because I'm not supplying the $coderoute parameter, the form is opened like this:
因为我没有提供$code路由参数，所以表单是这样打开的：
<form method="POST" action="http://site.dev/reset-password/%7Bcode%7D" accept-charset="UTF-8">
Obviously, this doesn't match the route I've defined (due to {code}not existing) and route matching fails. I need to somehow get the route parameter into my view so I can use it with Form::open(). I've tried doing this:
显然，这与我定义的路由不匹配（由于{code}不存在）并且路由匹配失败。我需要以某种方式将路由参数放入我的视图中，以便我可以将它与Form::open(). 我试过这样做：
{{ Form::open(array('route' => array('reset-password-confirm', $code))) }}
But that just throws an exception saying $codeis undefined.
但这只是抛出一个异常，说$code是未定义的。

The proper way to send the parameterto the view is:
将 发送parameter到视图的正确方法是：
return View::make('viewname')->with('code', $code);
Or you may use:
或者你可以使用：
return View::make('yourview', compact('code'));
So, the $codewill be available in your view and you may use it in your form but you may also use following approach to access a parameterin the view:
因此，$code将在您的视图中可用，您可以在表单中使用它，但您也可以使用以下方法parameter在视图中访问 a ：
// Laravel - Latest (use any one)
Route::Input('code');
Route::current()->getParameter('code');
Route::getCurrentRoute()->getParameter('code');
// Laravel - 4.0
Route::getCurrentRoute()->getParameter('code');

Maybe I don't clearly understand your question, but you can pass it to the view regularly (as you would pass any other variable, i.e.)
也许我不太明白你的问题，但你可以定期将它传递给视图（就像你传递任何其他变量一样，即）
public function resetPasswordConfirm($code)
{
return View::make('yourview')->with('code', $code);
}
and in the view $code will be defined:
并在视图中 $code 将被定义：
{{ Form::open(array('route' => array('reset-password-confirm', $code))) }}
orjust catch it in your view directly from the Request object:
或者直接从 Request 对象在您的视图中捕获它：
{{ Form::open(array('route' => array('reset-password-confirm', Request::segment(2) ))) }}
By the way, I think you could write your route also like this:
顺便说一句，我认为你也可以这样写你的路线：
Route::any('reset-password/{code}', array('as' => 'reset-password-confirm', 'uses' => 'UserController@resetPasswordConfirm'));
