Laravel blade templates, foreach variable inside URL::to?
提问by Sk446
I'm creating a basic list view of posts, and need a link to the 'edit' page.
我正在创建帖子的基本列表视图，需要一个指向“编辑”页面的链接。
I'm using blade, and what I have is a table, with a foreach loop, showing each post along with edit/delete buttons.
我正在使用刀片，我有一个表格，带有 foreach 循环，显示每个帖子以及编辑/删除按钮。
What I wanted to do is use blade's URL::to for the links to the edit and delete pages, to ensure consistant links.
我想要做的是使用刀片的 URL::to 链接到编辑和删除页面，以确保一致的链接。
The code I've tried using (remember this is inside a foreach loop hence the $post->id var) is this:
我尝试使用的代码（记住这是在 foreach 循环内，因此 $post->id var）是这样的：
<a href="{{ URL::to('admin/posts/edit/$post->id') }}" class="btn btn-mini btn-primary">Edit Post</a>
However this does not work. I've also tried
但是，这不起作用。我也试过
<a href="{{ URL::to('admin/posts/edit/<?php echo $post->id; ?>') }}" class="btn btn-mini btn-primary">Edit Post</a>
which also doesnt work.
这也不起作用。
I dont get any error, the link literally ends up being:
我没有收到任何错误，链接实际上最终是：
http://domain.dev/admin/posts/$post->id
Is there any way of working around this?
有没有办法解决这个问题？

I think the problem is that you are using php variable ($post) within a string with a single '. In this case it just outputs the name of the variable. Try this:
我认为问题在于您在带有单个'. 在这种情况下，它只输出变量的名称。尝试这个：
<a href="{{ URL::to('admin/posts/edit/' . $post->id) }}" class="btn btn-mini btn-primary">Edit Post</a>
Hope this helps. Vlad
希望这可以帮助。弗拉德

vlad has already given the right answer to your question but be aware that you can also directly link to your controller action via URL::action:
vlad 已经为您的问题提供了正确答案，但请注意，您也可以通过以下方式直接链接到您的控制器操作URL::action：
<a href="{{ URL::action('Admin\PostsController@edit', $post->id) }}">Edit</a>

I think this will work
我认为这会奏效
<a href="{{ url('test/'.$post->id.'/view') }}"></a>

The {{ }}are equal to <?php echo ;?>
该{{ }}等于<?php echo ;?>
if you put single '
如果你把单 '
<?php echo '$hello' ?>= $hello
<?php echo '$hello' ?>= $你好
but if you put double ' (")-> <?php "$hello" ;?>= Hello World (just one example)
但是如果你把 double ' (")-> <?php "$hello" ;?>= Hello World （只是一个例子）
You need to write something like {{ URL::to("admin/posts/edit/$post->id") }}
你需要写一些类似的东西 {{ URL::to("admin/posts/edit/$post->id") }}

Another way
其它的办法
<a href="{{URL::to('/')}}/admin/posts/edit/{{$post->id}}">Edit</a>

Also you may use route()helper to generate url by name of route. For example, definition of route:
您也可以使用route()helper 按路由名称生成 url。例如路由的定义：
Route::get('/test/mypage/{id}', 'MyController@myAction')->name('my_route_name');
Code in your view:
您认为的代码：
<a href="{{ route('my_route_name', $row['id']) }}">{{ $row['name'] }}</a>
