从下拉列表中选择总是返回第一条记录？

Question

我有下拉的问题，我总是得到第一个记录。有什么建议吗？

$category = $request->input('article_category');

<select class="form-control" name="article_category">
    <option value="" disabled>--Please select article category</option>
          @foreach ($categories as $category)
           <option value="{{ $category->id }}">{{ $category->title }}</option>
           @endforeach

Answer 1

请进行以下更改......

<select class="form-control" name="article_category">
  <option value="" disabled>--Please select article category</option>
  @foreach ($categories as $category)
    <option value="{{ $category->id }}" @if(request()->input('article_category') == $category->id){{ 'selected' }}@endif>{{ $category->title }}</option>
  @endforeach
</select>

1. 您的$category = $request->input('article_category')被foreach写的foreach($categories as $category) 覆盖。
2. 此外，您必须添加所选关键字，以便在页面加载时将选项标记为已选中。
