This article mainly shares with you the laravel framework search function implementation code, hoping to help everyone. The search function here is mainly implemented based on form get submission.

<form action="/backend/auditList" method="get">
  <table class="search_tab">
    <tr>
      <th width="120">选择分类:</th>
      <td>
        <select name="class" >
          <option value="">全部</option>
          @foreach($category as $c)
            <option value="{{$c->id}}">{{$c->class_name}}</option>
          @endforeach
        </select>
      </td>
      <th width="70">文章标题:</th>
      <!--查询关键词-->
      <td><input type="text" name="keywords" placeholder="文章标题"></td>
      <td><input type="submit" name="sub" value="查询"></td>
    </tr>
  </table>
</form>

public function article_list(){
  //echo &#39;zoule&#39;;exit; 测试表单是否走进方法中 大家随意写
  $shownum = 1;
