在codeigniter中将html转换为pdf

Question

我正在使用dompdf library将html内容转换为pdf.I。我遇到了一些问题。

1)我能够生成PDF，但在我的HTML内容上有一些图像，但当我生成pdf图像时，pdf格式的图像不会出现。

2)另外，PDF没有显示完整的数据，这意味着数据肯定会出现，但看不到完整的宽度。

请帮帮我！

Answer 1

这是我将html格式转换成pdf格式的示例……我希望我能给你一些想法。

库：

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Dompdf_gen {

    public function __construct() {

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

        $pdf = new DOMPDF();

        $CI =& get_instance();
        $CI->dompdf = $pdf;

    }

}

控制器：

function pdf($id){

            $data['contract_items_all']     = $this->contract_items->get_serial_infos($this->uri->segment(4));
            $data['child_info']             = $this->contract_items->get_children_info($cid);

            $this->load->library('dompdf_gen');
            $html = $this->load->view('contracts/equipment_pdf', $data, true);//this equipment_pdf contain the html that you will convert to pdf
            $this->load->library('dompdf_gen');
            $dompdf = new DOMPDF();

            // Convert to PDF
            $this->dompdf->load_html($html);
            $this->dompdf->render();
            $this->dompdf->stream("Contract.pdf",array("Attachment"=>0)); // VIEW IN OTHER TAB
            //$this->dompdf->stream("Contract.pdf"); // SAVE FILE TO DISK
    }

为什么要加载库两次？

// ...

$this->load->library('dompdf_gen');
$html = $this->load->view('contracts/equipment_pdf', $data, true);//this equipment_pdf contain the html that you will convert to pdf
$this->load->library('dompdf_gen');
$dompdf = new DOMPDF();

// ...
