Question

我正在尝试将3个参数从控制器传递到视图。出于某种原因，我只能发送2个参数，并且出现错误

未定义变量：第3个参数

我的路线

Route::get('/notification_list/notification_application/{user_id}/{notification_id}', 'AdminController@adminGetEachNotification')->name('show.notification_application');

我的控制器

public function adminNotificationList(){

        //$notifications = Notification::all() ;
        $data = [];
        $data['notifications'] = Notification::where(['approved'=>0])->get();

        $approvedData = [];
        $approvedData['approvednotifications'] = Notification::where(['approved'=>3])->get();

        $sendToAdmin = [];
        $sendToAdmin['sendtoadmin'] = Notification::where(['approved'=>1])->get();
        //dd($sendApproval);
        return view('Notification.notification_admin', $data, $approvedData, $sendToAdmin);
    }

我的观点

@extends('layouts.app')
@section('title',  '| Notification')
@section('content')

<!-- Page content -->
<div id="page-content-wrapper">
<!-- Keep all page content within the page-content inset div! -->
<div class="page-content inset">

  <div class="row">
    <div class="col-xs-12">
      <ul>
        <h1>Notifications</h1>
      </ul>

    </div>
  </div>

  <h2>New Application</h2>
  <div class="row">

任何人都可以指出我正确的方向。谢谢

Answer 1

您需要在第二个参数中将数据作为数组传递：

import static org.junit.Assert.*;

import javax.inject.Inject;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.jvnet.hk2.testing.junit.HK2Runner;
import org.mockito.Mockito;
import org.mockito.junit.MockitoJUnitRunner;

@RunWith(MockitoJUnitRunner.class)
public class MockTest extends HK2Runner {

    private B bMock = Mockito.mock(B.class);

    @Inject
    private A a;

    @Test
    public void test() {
        Mockito.when(bMock.toString()).thenReturn("Mock");
        assertEquals("Mocking worked", "Mock", a.test());
    }

}

或者：

return view('Notification.notification_admin', compact('data', 'approvedData', 'sendToAdmin'));

Answer 2

首先有两个问题是你没有使用正确的语法来传递变量来查看see here，第二个是你没有传递你在控制器中提取的相同变量。

试试这个，

在你的控制器中：

public function adminNotificationList(){  

            $notifications = Notification::where(['approved'=>0])->get();


            $approvednotifications = Notification::where(['approved'=>3])->get();

            $sendtoadmin = Notification::where(['approved'=>1])->get();

            return view('Notification.notification_admin', compact('notifications ', 'approvednotifications ', 'sendToAdmin'));

        }

然后您可以保持视图代码不变。

从控制器传递3个参数以查看Laravel
