Laravel is giving me Facade\Ignition\Exceptions\ViewException Undefined variable: GENERAL_SETTING
提问by Rismada Gerra Nindya
This is my controller code to show data from GENERAL_SETTING table
这是我的控制器代码，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' => $GENERAL_SETTING]);
}
This is the code in my view (home.blade.php)
这是我认为的代码（home.blade.php）
<div class="table-responsive">
<table class="table table-bordered">
@foreach($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>
And this is my routes (web.php)
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');
I try that code in other file (ex: dashboard.blade.php), that code can run normally. But, if I using home.blade.php, that error always show. What should I do to fix that error? Thank u.
我在其他文件中尝试该代码（例如：dashboard.blade.php），该代码可以正常运行。但是，如果我使用 home.blade.php，则始终会显示该错误。我该怎么做才能修复该错误？感谢你。

In your view()just remove the forward slash in /homeand it should look like this
在你view()刚刚删除正斜杠/home，它应该是这样的
return view('home',['GENERAL_SETTING' => $GENERAL_SETTING]);.
Just a piece of advice, your code is very poor and you should do it like this
只是一个建议，你的代码很差，你应该这样做
Controller
控制器
public function show()
{
// mengambil data dari table GENERAL_SETTING
$generalSettings = GeneralSetting::all();
// mengirim data GENERAL_SETTING ke view /home
return view('/home',['generalSettings' => $generalSettings]);
}
Blade
刀刃
@foreach($generalSettings as $gs)
//
@endforeach
