php - Laravel 给我 Facade\Ignition\Exceptions\ViewException Undefined variable : GENERAL_SETTING

Question

这是我的 Controller 代码，用于显示 GENERAL_SETTING 表中的数据

    public function show()
    {
        // mengambil data dari table GENERAL_SETTING
        $GENERAL_SETTING = GeneralSettingModel::all();

        // mengirim data GENERAL_SETTING ke view /home
        return view('/home',['GENERAL_SETTING' => $GENERAL_SETTING]);
    }

这是我认为的代码(home.blade.php)

<div class="table-responsive">
    <table class="table table-bordered">
        @foreach($GENERAL_SETTING as $gs)
        <thead class="bg-primary">
            <tr class="border-1">
                <th scope="col" colspan="2" class="border-1">Hardware</th>
                <th scope="col" colspan="2" class="border-1">Communication</th>
                <th scope="col" class="border-1">Master Clock</th>
            </tr>
        </thead>
        <tbody>
            <tr>
                <td colspan="2" >IP: {{ $gs->IP_HW }}</td>
                <td colspan="2" >SNMP Driver
                    <br>
                        Status: Connected
                    </br>
                </td>
                <td rowspan="4">IP: IP: {{ $gs->IP_MC }}
                    <br>
                        Status: Connecteds
                    </br>
                </td>
            </tr>
            <tr>
                <td colspan="2" >Temperature: 31</td>
                <td colspan="2" >Cloud Driver
                    <br>
                        URL: <a href="cloud.mqtt.com" target="_blank"> cloud.mqtt.com </a>
                    </br>
                    <br>
                        Status: Connected
                    </br>
                </td>
            </tr>
            <tr>
                <td class="bg-primary">Main</td>
                <td class="bg-primary">Backup</td>
                <td class="bg-primary">Master Driver</td>
                <td class="bg-primary">Slave Driver</td>
            </tr>
            <tr>
                <td>IP: {{ $gs->IP_SERVER1 }}
                    <br>
                        Status: Connected
                    </br>
                </td>
                <td>IP: {{ $gs->IP_SERVER2 }}
                    <br>
                        Status: Connected
                    </br>
                </td>
                <td>IP: 192.168.1.15
                    <br>
                        Status: Connected
                    </br>
                </td>
                <td>IP: 192.168.1.16
                    <br>
                        Status: Connected
                    </br>
                </td>
            </tr>
        </tbody>
        @endforeach
    </table>
</div>

这是我的路线(web.php)

Auth::routes();
Route::get('/home', 'FEPController@home');
Route::get('/home','GeneralSettingController@show');
Route::get('/home', 'HomeController@index')->name('home');

我在其他文件(例如:dashboard.blade.php)中尝试该代码，该代码可以正常运行。但是，如果我使用 home.blade.php，该错误总是会显示。我应该怎么做才能修复该错误？谢谢你。

Answer 1

在您的 view() 中，只需删除 /home 中的正斜杠，它应该如下所示

 return view('home',['GENERAL_SETTING' => $GENERAL_SETTING]);.

只是一个建议，你的代码很糟糕，你应该这样做

Controller

public function show()
{
    // mengambil data dari table GENERAL_SETTING
    $generalSettings  = GeneralSetting::all();

    // mengirim data GENERAL_SETTING ke view /home
    return view('/home',['generalSettings' => $generalSettings]);
}

Blade

 @foreach($generalSettings as $gs)
   //
 @endforeach
