我有一個概覽網站，頂部有一個過濾器。用戶可以對位置和部門進行篩選。
控制器的代碼如下所示：
public function index(Request $request)
{
$posts = Post::orderBy('titel')
->get();
$standorts = Standort::get();
$abteilungs = Abteilung::get();
if ($request->filled('s')) {
$query = strtolower($request->get('s'));
$posts = $posts->filter(function ($post) use ($query) {
if (Str::contains(strtolower($post->Titel), $query)) {
return true;
}
return false;
});
}
return view('posts.overview', ['posts' => $posts], ['standorts' => $standorts]);
}
我需要提供$abteilungs = Abteilung::get();aswell，但是當我像這樣回傳它時：
return view('posts.overview', ['posts' => $posts], ['standorts' => $standorts], ['abteilungs' => $abteilungs]);
括號中的最后一部分是灰色的，我無法訪問它。
在刀片檔案中，我像這樣訪問它們：
<div class="text-left mb-4 h-12">
<select name="standort" id="standort" class="h-full w-full flex justify-center bg-white bg-opacity-95 rounded focus:ring-2 border border-gray-300 focus:border-indigo-500 text-base

@foreach($standorts as $standort)
<option value="{{ $standort->standort_name }}">{{ $standort->standort_name }}</option>
@endforeach
</select>

</div>
</div>
</a>
</div>
@endforeach
對于回傳陳述句中的第三部分，我有以下代碼：
<div class="text-left mb-4 h-12">
<select name="abteilung" id="abteilung" class="h-full w-full flex justify-center bg-white bg-opacity-95 rounded focus:ring-2 border border-gray-300 focus:border-indigo-500 text-base
outline-none text-gray-700 text-lg text-center leading-8">
<option selected="true" disabled="disabled">Abteilung</option>
@foreach($abteilungs as $abteilung)
<option value="{{ $abteilung->abteilung_name }}">{{ $abteilung->abteilung_name }}</option>
@endforeach
</select>
</div>
有沒有辦法讓這個作業或者回傳視圖僅限于兩個引數？

你也可以這樣試試
$data = [
'posts' => $posts,
'standorts' => $standorts,
'abteilungs' => $abteilungs,
];
return view('posts.overview')->with($data);
或者，
return view('post.overview',compact('posts','standorts','abteilungs'));
uj5u.com熱心網友回復：
您可以通過多種方式傳遞變數以查看..
方式一：
$variables = [
'variable1'=>'something goes here',
'variable2'=>'something goes here',
];
return view('view-file')->with($variables );
方式二：
return view('view-file')->with(['variable1'=>'something goes here','variable2'=>'something goes here']);
方式3：
$variable1 = 'something goes here';
$variable2 = 'something goes here';
return view('view-file')->withVariabl1($variable1);
or
return view('view-file')->withVariabl2($variable2);
or
return view('view-file')
->withVariable2($variable2)
->withVariable1($variable1);
方式四
$variable1 = 'something goes here';
$variable2 = 'something goes here';
return view('view-file',compact('variable1','variable2'));
希望您清楚如何以多種方式發送變數以查看。如果您想傳遞 1 或 2 個變數，并且以后不需要增加變數，則建議使用方式 4。但從我的觀點和現實生活經驗來看，我總是建議使用方式 1
uj5u.com熱心網友回復：
要將多個變數傳遞給您的視圖，您應該這樣做
return view('posts.overview', ['posts' => $posts, 'standorts' => $standorts, 'abteilungs' => $abteilungs]);
uj5u.com熱心網友回復：
在視圖方法中，第二個引數用于將資料傳遞給視圖，您可以傳遞任意數量的變數，如下所示：
return view('post.review',['variableOne' => $variableOne,'variableTwo' => `$variableTwo,'variableThree' => $variableThree])`
