從Laravel導出PDF

Question

我想導出PDF格式的表格，但我有一個foreach，我想從foreach中導出所有數據，但不適用於所有，僅適用於一行。

下面是代碼：

foreach ($posts as $post) { 
    $html = '<div class="table-scrollable"> 
        <table id="posts" class="table table-bordered table-hover"> 
         <thead> 
          <tr> 
           <th>Id</th> 
           <th>Name</th> 
           <th>Title</th> 
          </tr> 
         </thead> 
         <tbody id="body"><tr> 
          <td>' 
      . $post->id . ' 
          </td> 
          <td>' . 
      $post->name . 
      '</td> 
          <td>' 
      . $post->title . 
      '</td> 
       </tr> 
       </tbody> 
      </table> 
     </div>'; 
} 
return PDF::load($html, 'A4', 'portrait')->download('my_pdf');

內部foreach構造你重寫你的$html變量，需要foreach之前初始化$html並添加使用連接賦值.=

$html = ''; 
foreach ($posts as $post) { 
     $html .= '<div class="table-scrollable"> 
         <table id="posts" class="table table-bordered table-hover"> 
          <thead> 
           <tr> 
            <th>Id</th> 
            <th>Name</th> 
            <th>Title</th> 
           </tr> 
          </thead> 
          <tbody id="body"><tr> 
           <td>' 
       . $post->id . ' 
           </td> 
           <td>' . 
       $post->name . 
       '</td> 
           <td>' 
       . $post->title . 
       '</td> 
        </tr> 
        </tbody> 
       </table> 
      </div>'; 
} 
return PDF::load($html, 'A4', 'portrait')->download('my_pdf');
