Laravel 給我 Facade\Ignition\Exceptions\ViewException 未定義變量：GENERAL_SETTING

Question

這是我的 controller 代碼，用於顯示 GENERAL_SETTING 表中的數據

    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]);
    }

這是我認為的代碼（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>

這是我的路線（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）中嘗試該代碼，該代碼可以正常運行。 但是，如果我使用 home.blade.php，則始終會顯示該錯誤。 我應該怎么做才能修復該錯誤？ 感謝你。

Answer 1

在您的view()中，只需刪除/home中的正斜杠，它應該看起來像這樣

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

只是一條建議，你的代碼很差，你應該這樣做

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]);
}

刀

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