Question

我有多个复选框，可以从数据库中检索这些值。每个复选框都有一个选择/下拉列表，用户可以将其更改为low, medium, high并更新值。我的问题是更新不起作用，下拉/选择只返回选项中的第一项。用户应该能够一次更改多个项目。

查看

<form method="post" action="{{ route('allergies.update', ['id'=>Auth::user()->id]) }}" enctype="multipart/form-data">
    <input type="hidden" name="_token" value="{{ csrf_token() }}">
    @foreach($userallergens as $aller)
        <br>
        <input type="hidden" name="ua_id" value="{{$aller->ua_id}}">
        <select name="tolerance[]">
            <option value="Low">Low</option>
            <option value="Medium">Medium</option>
            <option value="High">High</option>
        </select>
        <label style="color:black" name="allergen[]" value="{{$aller->ua_id}}">
            {{ $aller->allergen_name}}
        </label>
    @endforeach
</form>

控制器

<?php

public function update2(Request $request, $id)
{
    $user = User::find($id);
    for ($j = 0; $j < count($request['tolerance']); $j++) {
        $user = UserAllergen::where('ua_id', $request['ua_id'])
            ->where('user_id', $user)
            ->update(['tolerance_level' => $request['tolerance'][$j]]);
    }

    return redirect()->route('user.profile', compact('id', 'user'));
}

Answer 1

试试这段代码，希望它会对你有帮助。

public function update2(Request $request, $id){
     $user = Auth::user()->id;
     $data = $request->all();
     $tolerances = $data['tolerance'];
     foreach($tolerances as $tolerance)
     {
         $this->updateData($data['ua_id'], $user, $tolerance);
     }

     return redirect()->route('user.profile', compact('id', 'user'));
}

public function updateData($ua_id, $user, $tolerance_level)
{
    UserAllergen::updateOrCreate(
        ['ua_id' => $ua_id, 'user_id' => $user],
        [
            'tolerance_level'          => $tolerance_level
        ]
    );
}

Answer 2

添加多个属性以选择多个项目。

<select name="tolerance[]" multiple>

从Laravel中的复选框更新项目
