Laravel - Pass object through view and use in blade
提问by Vaughan Slater
Basically, I've a simple 'exp' column in my database and I want to use a function 'showLevel()' where I can pass in Auth::user->usernameas the argument instead of a static name. I'm struggling with how I can use either a function in an echo on my template or with an object.
基本上，我的数据库中有一个简单的“exp”列，我想使用一个函数“showLevel()”，我可以在其中Auth::user->username作为参数而不是静态名称传入。我正在努力解决如何在我的模板或对象的回声中使用函数。
public function index()
{
$users = User::all();
$level = $this->showLevel('test');
return view('home')->with('users', $users)->with('showLevel', $level);
}
public function showLevel($username) {
$level = DB::table('users')->where('username', $username)->pluck('exp');
if ($level < 500) {
return 1;
} else if ($level > 500 && $level < 1000) {
return 2;
} else if ($level > 1000 && $level < 1500) {
return 3;
} else if ($level > 1500 && $level < 2000) {
return 4;
} else if ($level > 2000 && $level < 2500) {
return 5;
} else if ($level > 2500) {
return 'MAX';
}
}
I tried creating an object in home.blade.php.
我尝试在 home.blade.php 中创建一个对象。
$level = new HomeController;
$level->showLevel(Auth::user->username);
But that didn't seem to work. Can you pass objects in blade? I've been trying to look this up myself but maybe I'm wording it wrong. I'm stuck!
但这似乎不起作用。你能在刀片中传递物体吗？我一直在尝试自己查找，但也许我的措辞有误。我被卡住了！
I basically want to be able to do something like {{ showLevel(Auth::user->username); }}in my home.blade.php to echo the level that's returned from the function.
我基本上希望能够{{ showLevel(Auth::user->username); }}在我的 home.blade.php 中做一些事情来回显从函数返回的级别。

Try something like this:
尝试这样的事情：
use Auth;
$level = new HomeController();
$data = $level->showLevel(Auth::user()->username);
and Return Blade::
和返回刀片::
return view('home')->with(['data'=>$data]);
Now, In Your Blade You Can Use $data
现在，在你的刀片中你可以使用 $data

Yes, you can pass an object to blade. You use the compact method to achieve that:
是的，您可以将对象传递给刀片。您使用紧凑方法来实现：
return view('home')->with(compact('users'));
In your blade you can access users like this:
在您的刀片中，您可以像这样访问用户：
@if ($users)
@foreach($users as $user)
{{ $user->name }}
@endforeach
@endif
回答by Panda Zhang
return view('home', compact('users'));
than you can foreach it on your blade.php
比你可以在你的blade.php 上 foreach
