這里的搜索功能主要基于表單get提交實現的:

1. <form action="/backend/auditList" method="get"> 
2.   <table class="search_tab"> 
3.     <tr> 
4.       <th width="120">選擇分類:</th> 
5.       <td> 
6.         <select name="class" > 
7.           <option value="">全部</option> 
8.           @foreach($category as $c) 
9.             <option value="{{$c->id}}">{{$c->class_name}}</option> 
10.           @endforeach 
11.         </select> 
12.       </td> 
13.       <th width="70">文章標題:</th> 
14.       <!--查詢關鍵詞--> 
15.       <td><input type="text" name="keywords" placeholder="文章標題"></td> 
16.       <td><input type="submit" name="sub" value="查詢"></td> 
17.     </tr> 
18.   </table> 
19. </form> 

php部分邏輯:

1. public function article_list(){ 
2.   //echo 'zoule';exit; 測試表單是否走進方法中 大家隨意寫 
3.   $shownum = 1; 
4.   if(array_key_exists('class',$_GET)||array_key_exists('keywords',$_GET)){ 
5.    //echo '111';  
6.    if($_GET['class']){ 
7.    //Article模型 leftJoin表連接 查詢根據倆個表里的這些字段來執行 
8.      $postdata = Article::leftJoin('category', function($join) { 
9.       $join->on('article.class_id', '=', 'category.id'); 
10.      })->select(['article.id','category.class_name','article.status','article.title_editing','article.update_time'])->where('article.class_id','=',$_GET['class'])->orderBy('release_time','desc')->paginate($shownum); 
11.    }elseif($_GET['keywords']){ 
12.      $postdata = Article::leftJoin('category', function($join) { 
13.       $join->on('article.class_id', '=', 'category.id'); 
14.      })->select(['article.id','category.class_name','article.status','article.title_editing','article.update_time'])->where('article.title_editing','=',$_GET['keywords'])->orderBy('release_time','desc')->paginate($shownum); 
15.       
16.    }else{ 
17.      $postdata = Article::leftJoin('category', function($join) { 
18.       $join->on('article.class_id', '=', 'category.id'); 
19.      })->select(['article.id','category.class_name','article.status','article.title_editing','article.update_time'])->orderBy('release_time','desc')->paginate($shownum); 
20.    } 
21.   }else{ 
22.    //echo '2222'; 
23.    $postdata = Article::leftJoin('category', function($join) { 
24.      $join->on('article.class_id', '=', 'category.id'); 
25.    })->select(['article.id','category.class_name','article.status','article.title_editing','article.update_time'])->orderBy('release_time','desc')->paginate($shownum); 
26.   } //Vevb.com 
27.   //分類id不是父id 
28.   $category = DB::table('category')->where('parent_id','!=','0')->get(); 
29.   //渲染頁面 傳遞 參數 
30.   return view('backend.article_list',['postdata'=>$postdata,'shownum'=>$shownum,'category'=>$category]); 
31. }
