在laravel中的编辑表单上获取选择的选项 [英] Getting selected option on edit form in laravel

问题描述

我的网站订单具有可编辑的表单，并且具有以下字段:

I have an editable form for my website orders and I have these fields:

User quantity note status

此格式中还有其他选项，但是只有这些字段对我很重要，以便能够获取默认值.

I also have other options in this form, but only these fields are important to me in order to be able to get the default values.

例如，我希望能够查看用户默认订购的数量，然后我可以对其进行更改或不加更改.目前，我所有的下拉值都从第一个值开始，而不是用户选择的值.

For example, I want to be able to see the amount of quantity that a user has ordered by default and then I could change it or leave it alone. Currently all my drop-down values start from the first value and not what the user has chosen.

我该怎么办?

这是我的表格:

{{ Form::model($order, array('route' => array('orders.update', $order->id), 'method' => 'PUT', 'files' => true)) }}

                <div class="form-group">
                  <label class="col-md-3 control-label" for="type">Order ID</label>
                  <div class="col-md-9 inputGroupContainer">
                    <div class="input-group">

                      <input class="form-control" type="text" name="" value="{{ $order->id }}" readonly>
                    </div>
                  </div>
                </div>


                <div class="form-group">
                  <label class="col-md-3" for="invoice_nu">Invoice Number:</label>

                {{ Form::close() }}

推荐答案

您可以将$order->quantity与选项值进行比较以添加selected属性

you can compare $order->quantity with option value to add selected attribute

<select class="form-control" id="type" name="quantity">
    <option value="">Select Quantity</option>
    <option value="1" {{ $order->quantity == 1 ? 'selected' : '' }}>1</option>
    <option value="2" {{ $order->quantity == 2 ? 'selected' : '' }}>2</option>
    <option value="3" {{ $order->quantity == 3 ? 'selected' : '' }}>3</option>
    <option value="4" {{ $order->quantity == 4 ? 'selected' : '' }}>4</option>
    <option value="5" {{ $order->quantity == 5 ? 'selected' : '' }}>5</option>
</select>

供用户比较$user->id与$order->user_id(或其他根据您的数据)

for user compare $user->id with $order->user_id (or something else according your data)

<select class="form-control" id="type" name="user_id">
    @foreach($users as $user)
        <option value="{{ $user->id }}" {{ $user->id == $order->user_id ? 'selected' : '' }}>{{ $user->name }}</option>
    @endforeach
</select>
