在 Laravel 8 中从数据库中获取和打印数据

Question

您好，我刚开始在 laravel 8 中工作，我想知道如何在数据库中获取数据并打印数据

我有一个带有搜索栏的表格模板，可以在我们的数据库中查看和查找用户

这是我们的表格控制器

仪表板控制器

<?php

namespace App\Http\Controllers;

use Auth;
use Illuminate\Http\Request;

class DashboardController extends Controller
{
    public function dashboard()
    {
        $dashboardTitle = "Dashboard";
        $isCurrent = "dashboard";

        return view('dashboard.index', [
            'dashboardTitle' => $dashboardTitle,
            'isCurrent' => $isCurrent
        ]
    );
    }
    public function profile()
    {
        $dashboardTitle = "Profile";
        $isCurrent = "Profile";
        return view('dashboard.profile', [
            'dashboardTitle' => $dashboardTitle,
            'isCurrent' => $isCurrent
        ]
    );
    }
    public function directory()
    {
        $dashboardTitle = "Directory";
        $isCurrent = "Directory";
        return view('dashboard.directory', [
            'dashboardTitle' => $dashboardTitle,
            'isCurrent' => $isCurrent
        ]
    );
    }
    public function journal()
    {
        $dashboardTitle = "Journal";
        $isCurrent = "Journal";
        return view('dashboard.journal', [
            'dashboardTitle' => $dashboardTitle,
            'isCurrent' => $isCurrent
        ]
    );
    }
    public function files()
    {
        $dashboardTitle = "Files";
        $isCurrent = "Files";
        return view('dashboard.files', [
            'dashboardTitle' => $dashboardTitle,
            'isCurrent' => $isCurrent
        ]
    );
    }
}

我们的表名是 users，我想使用循环将其打印在表中

Answer 1

数据库 如果您还没有（职位、办公室...），请在数据库中添加新行

控制器

...
$users = User::all();
return view('dashboard.directory', [
     'users' => $users
        ]
...

刀片

@foreach($users as $user)
  <tr>
    <td>{{ $user->name }}</td>
    <td>{{ $user->postion }}</td>
    <td>{{ $user->office }}</td>
    <td>{{ $user->age }}</td>
    <td>{{ $user->start_date }}</td>
    <td>{{ $user->salary }}</td>
  </tr>
@endforeach

Answer 2

要检索数据库中的所有用户，您必须：

仪表板控制器

public function directory(){
    $dashboardTitle = "Directory";
    $isCurrent = "Directory";
    $users = User::all();
    return view('dashboard.directory', [
        'dashboardTitle' => $dashboardTitle,
        'isCurrent' => $isCurrent,
        'users' => $users
    ]);
}

在刀片中

@foreach($users as $user)
  <tr>
    <td>{{ $user->name }}</td>
    <td>{{ $user->postion }}</td>
    <td>{{ $user->office }}</td>
    <td>{{ $user->age }}</td>
    <td>{{ $user->start_date }}</td>
    <td>{{ $user->salary }}</td>
  </tr>
@endforeach
