在选择2下拉列表

Question

我的更新表单中有一个选择框，其中包含不同的付款方式。我需要选择多个数据。如果用户已在表中具有付款类型，则获取数据并在selectbox中加载。我添加了这些功能，但是在下拉列表中多次显示数据。请找到我附上的图片。

实际上用户有三种付款方式。下拉列表显示这些付款类型三次。

请检查下面给出的代码并纠正我。

$cabin->payment_type = payment type from user table

$cabinInfo->paymentType() = Generating array in controller

update.blade.php

@inject('cabinInfo', 'App\Http\Controllers\Cabinowner\DetailsController')
    <select id="payment" name="payment" class="form-control payment" multiple="multiple" data-placeholder="Choose payment type" style="width: 100%;">
       @foreach($cabin->payment_type as $payment)
          @foreach($cabinInfo->paymentType() as $paymentTypeKey => $paymentType)
             <option value="{{ $paymentTypeKey }}" @if($paymentTypeKey == $payment || old('payment') == $payment) selected="selected" @endif>{{ $paymentType }}</option>
          @endforeach
       @endforeach
</select>

脚本

/* Multiple select for payment */
$(".payment").select2();

UpdateController.php

public function index()
{
    $cabin       = Cabin::where('id', Auth::user()->id)
        ->first();
    return view('update', ['cabin' => $cabin]);
}


public function paymentType()
{
    $array = array(
        '0' => "Cash",
        '1' => "Debit Card",
        '2' => "Credit Card",
    );

    return $array;
}

我假设$cabin->payment_type返回一个数组？如果是这样你的逻辑应该更像这样：

@inject('cabinInfo', 'App\Http\Controllers\Cabinowner\DetailsController')
    <select id="payment" name="payment" class="form-control payment" multiple="multiple" data-placeholder="Choose payment type" style="width: 100%;">
        @foreach($cabinInfo->paymentType() as $paymentTypeKey => $paymentType)
           <option value="{{ $paymentTypeKey }}" @if(in_array($paymentTypeKey, $cabin->payment_type )|| in_array(old('payment'), $cabin->payment_type )) selected="selected" @endif>{{ $paymentType }}</option>
        @endforeach
</select>
