Question

我正在使用Code Igniter v 2.2和最新的MPDF开发我的简单应用程序，以便将我的视图转换为PDF。我已经按照此链接进行教程了 Using MPDF with CI

我无法获得PDF输出。：d

我认为WriteHTML()函数无法呈现我的视图。这是我的代码

$this->load->library('m_pdf');
$pdf = $this->m_pdf->load();
$html = $this->load->view('cetak', true);
$pdf->WriteHTML($html);

但是当我将$ html变量更改为这样的HTML标记时，它可以正常工作。

$html = " <!DOCTYPE html>
      <html lang='en'>
      <head>
      <meta charset='utf-8'>
      <meta http-equiv='X-UA-Compatible' content='IE edge'>
      <meta name='viewport' content='width = device-width, initial-scale = 1'>
      <!-- The above 3 meta tags *must* come first in the head; any other head content must come *after* these tags -->
      <meta name='description' content=''>
      <meta name='author' content=''>
      <link rel='icon' href='../../favicon.ico'>

      </tr>

      </table>
      </div>
      <?php
      }
      ?>
      </div>
      <?php
      }
      ?>
      </div> <!-- /container -->
      </body>
      </html>";

谁能告诉我我的错误在哪里？问候。

Answer 1

你错过了从视野中获取字符串。这是因为您将AS class_id传递给第二个参数。第二个参数应为空或true，第三个参数需要设置为布尔值以获取字符串：

null

试试这种方式。

Answer 2

你的html用双引号括起来。尝试使用单引号。您的所有单引号都需要转义或更改为双引号。
