Use session data in Blade - Laravel
提问by WellNo
I've created a new session in my controller and filled it with some data from my database.
我在我的控制器中创建了一个新会话，并用我的数据库中的一些数据填充了它。
Thats the controller code:
那是控制器代码：
public function index(Request $request) {
$products = Products::with('categories')->get()->take(5);
$request->session()->put('session_products', $products);
return view('shoppingcard.card');
}
and in the next controller function I retrieve the session data.
在下一个控制器函数中，我检索会话数据。
public function receiver(Request $request) {
if($request->session()->has('session_products')) {
echo $request->session()->get('session_products');
}
else return "stop no session";
return view('shoppingcard.endview');
}
Now if I do a : return $request->session()->get('session_products');I get everything I need.
现在如果我做一个：return $request->session()->get('session_products');我得到了我需要的一切。
Here is a dummy data of the content from the session:
这是会话内容的虚拟数据：
{"id":5,"title":"Beautiful Unicorn","price":"20.00","sale_price":"15.00","status":"active","created_at":null,"updated_at":null,}
Now I'm in the endview blade and want to output the Data.
现在我在 endview 刀片中并想输出数据。
How can I output specific Data like the "title" ?
我怎样才能输出像“标题”这样的特定数据？

That data is serialized to session and unserialized back to a object. All you need is to use that info exactly the way you normally would:
该数据被序列化到会话并反序列化回对象。您所需要做的就是完全按照通常的方式使用该信息：
public function receiver(Request $request) {
if(! $request->session()->has('session_products')) {
return "stop no session";
}
return view('shoppingcard.endview')
->with('title', $request->session()->get('session_products')[0]['title']);
}
Or you can just pass it all to your view:
或者您可以将其全部传递给您的视图：
public function receiver(Request $request) {
if(! $request->session()->has('session_products')) {
return "stop no session";
}
return view('shoppingcard.endview')
->with('products', $request->session()->get('session_products'));
}
And use it in the view:
并在视图中使用它：
@foreach($products as $product)
{{ $product['title'] }}
@endforeach

your session save the products as json. you can decode it with json_decode, then access each of the products.
您的会话将产品保存为 json。您可以使用 json_decode 对其进行解码，然后访问每个产品。
code as:
代码为：
$products = json_decode($request->session()->get('session_products'), true);
foreach($products as $product)
{
echo $product['title'];
}

Well in order to access the title element you need to convert the json string to a array. To do this you need to use php's json_decodefunction to decode the string and then access the array like so:
好吧，为了访问标题元素，您需要将 json 字符串转换为数组。为此，您需要使用 php 的json_decode函数来解码字符串，然后像这样访问数组：
$decodedJsonString = json_decode($request->session()->get('session_products'), true);
access it like $decodedJsonString[id]['title'];
访问它就像 $decodedJsonString[id]['title'];

use laravel's with() or compact() method to send it to the view
使用 Laravel 的 with() 或 compact() 方法将其发送到视图
with() and compact are both eloquent methods
with() 和 compact 都是雄辩的方法
