如何在Laravel中将变量从一个控制器传递到另一个控制器

问题描述

我有一个名为index.blade.php的视图，该视图显示有关供应商的信息，该信息是通过控制器传递的，例如VendorController，在此视图上，我有一个查看地址"按钮，现在我想在单击按钮时显示此供应商的数据.我还有另一个控制器，即VendorAddressController，它从数据库中获取供应商的地址. index.blade.php文件的代码:

I have a view named index.blade.php which shows information about a vendor, which was passed through a Controller e.g. VendorController, on this view I have a button "View address", now I want to display the data of this vendor on button click. I also have another controller namely VendorAddressController which fetches the address of the vendor from the db. Code of index.blade.php file :

<td>
   <a href="{!! $vendor->slug !!}/vendor-address/" class="btn btn-primary">View Address</a>
</td>

在VendorAddressContoller中

in VendorAddressContoller

public function index($id)
{
    $vendor = Vendors::find($id);
    $vendorsaddress = VendorAddress::where('vendor_id', $vendor->id)->paginate(15);
    return view('admin.vendoraddress.index',['vendorsaddress'=>$vendorsaddress, 'vendor'=>$vendor, 'address'=>$address]);
}

但是当我单击按钮时，什么都没出现

But when i click on button nothing is coming

推荐答案

有多种方法可以做到这一点.您可以根据需要选择多种选择.

There is a multiple way to do that. You can choose one the many choice as per your requirement.

1..通过会话

您可以在第一个控制器中完成

You can do this in the first controller

Session::put('key', 'value');

然后在第二个

Session::get('key');

2..通过Cookie 您的第一个控制器:

2. By CookiesYour first controller:

$response = Response::make('Hello World');

return  $response->withCookie(Cookie::make('name', 'value', $minutes));

并在下一个请求中获取它

And get it in the next request

$value = Cookie::get('name');

您可以在此处.
