我试图让 dompdf 与 codeigniter 一起工作，我从这里下载文件https://github.com/dompdf/dompdf/releases版本是 0.7.0 然后我在我的控制器中放了一段这样的代码

public function generatepdf(){

        $this->load->helper('file');
        require_once(APPPATH.'third_party/dompdf/autoload.inc.php');

         $domdpf = new DOMPDF();
         $domdpf -> loadHtml('<h1>HELLO WORLD</h1>');
         $domdpf -> setPaper('A4','Landscape');
         $domdpf ->render();

You need to use v0.6. v0.7 uses namespaces which are not supported in CodeIgniter.

您需要使用 v0.6。v0.7 使用了 CodeIgniter 不支持的命名空间。

@Zedd Answer is right

@Zedd 答案是对的

but for the latest version as on this post date, the following will work.

但是对于此发布日期的最新版本，以下内容将起作用。

application/libraries/Pdf.php

应用程序/库/PDF.php

<?php defined('BASEPATH') OR exit('No direct script access allowed');
/**

*/

require_once APPPATH.'third_party/dompdf/autoload.inc.php';

use Dompdf\Dompdf;
class Pdf extends DOMPDF
{
/**
 * Get an instance of CodeIgniter
 *
 * @access  protected
 * @return  void
 */
protected function ci()
{
    return get_instance();
}

/**
 * Load a CodeIgniter view into domPDF
 *
 * @access  public
 * @param   string  $view The view to load
 * @param   array   $data The view data
 * @return  void
 */
public function load_view($view, $data = array())
{
    $dompdf = new Dompdf();
    $html = $this->ci()->load->view($view, $data, TRUE);

    $dompdf->loadHtml($html);

    // (Optional) Setup the paper size and orientation
    $dompdf->setPaper('A4', 'landscape');

    // Render the HTML as PDF
    $dompdf->render();
    $time = time();

    // Output the generated PDF to Browser
    $dompdf->stream("welcome-". $time);
}
}

At your controller

在您的控制器

function pdf_gen(){

    $this->load->library('pdf');
    $this->pdf->load_view('main_report');
}

Obviously main_report is the view file at application/views/main_report and you can send data for the view file like the following too

显然 main_report 是 application/views/main_report 中的视图文件，您也可以发送视图文件的数据，如下所示

$this->pdf->load_view('main_report', $data);

And Note

并注意

I placed the dompdf folder in the application/thirdparty folder and not in the application/libraries.

我将 dompdf 文件夹放在 application/thirdparty 文件夹中，而不是在 application/libraries 中。

Make sure you have commented out all print, echo functions in your controller method, else you might get an error saying something similar to "the pdf file is damaged".

确保您已注释掉控制器方法中的所有打印、回显功能，否则您可能会收到类似于“pdf 文件已损坏”的错误消息。

Hope this post was usefull.

希望这篇文章有用。

You can integrate the DomPDF with Codeigniter in two easy steps.

您可以通过两个简单的步骤将 DomPDF 与 Codeigniter 集成。

1) Downloadthe domPDF library and place it into application/library directory.

1) 下载domPDF库，放到application/library目录下。

2) Create a file name pdf.phpfile, place following code inside the file and place it into library directory.

2) 创建一个文件名pdf.php文件，将以下代码放入文件中并放入库目录中。

<?php defined('BASEPATH') OR exit('No direct script access allowed');
 /**


* CodeIgniter PDF Library
 *
 * Generate PDF's in your CodeIgniter applications.
 *
 * @package         CodeIgniter
 * @subpackage      Libraries
 * @category        Libraries
 * @author          Chris Harvey
 * @license         MIT License
 * @link            https://github.com/chrisnharvey/CodeIgniter-PDF-Generator-Library



*/

require_once(dirname(__FILE__) . '/dompdf/dompdf_config.inc.php');

class Pdf extends DOMPDF
{
    /**
     * Get an instance of CodeIgniter
     *
     * @access  protected
     * @return  void
     */
    protected function ci()
    {
        return get_instance();
    }

    /**
     * Load a CodeIgniter view into domPDF
     *
     * @access  public
     * @param   string  $view The view to load
     * @param   array   $data The view data
     * @return  void
     */
    public function load_view($view, $data = array())
    {
        $html = $this->ci()->load->view($view, $data, TRUE);

        $this->load_html($html);
    }
}
?>

Now in your Controllerfile call it as this

现在在您的控制器文件中将其称为

defined('BASEPATH') OR exit('No direct script access allowed');
class Welcome extends CI_Controller {
 function my_DOMPDF(){
  $this->load->library('pdf');
  $this->pdf->load_view('common/template');
  $this->pdf->render();
  $this->pdf->stream("welcome.pdf");
 }
}

Since v. 0.7 you need to include in your code reference to dompdfs namespace:

从 v. 0.7 开始，您需要在代码中包含对 dompdfs 命名空间的引用：

use Dompdf\Dompdf;

The simplest way creating PDF file. Download the library from
https://github.com/hanzzame/ci3-pdf-generator-library
Extract zip at app/application/libraries/extract-here

创建 PDF 文件的最简单方法。从
https://github.com/hanzzame/ci3-pdf-generator-library下载库
提取 zip 位于 app/application/libraries/extract-here

Use in method of Controller:

在Controller的方法中使用：

$this->load->library('pdf'); // change to pdf_ssl for ssl
$filename = "Document_name";
$html = $this->load->view('your_view_template');
$this->pdf->create($html, $filename);
