從下拉菜單中選擇總是返回第一條記錄？

Question

我有一個下拉的問題，我總是得到第一個記錄。任何建議？

$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

請進行以下變化...

<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. 你$category = $request->input('article_category')漸漸改寫以書面的foreach中的foreach($categories as $category)。
2. 此外，您還必須添加選擇關鍵字在頁面加載作爲選擇標記的選項。
