[英]PDF Generation using Dompdf in codeigniter redirects to a 404 page in case of large pdf files
[英]PDF generation using DOMpdf in CodeIgniter
我正在嘗試使用dompdf生成pdf。
<?php
if (!defined('BASEPATH'))
exit('No direct script access allowed');
class Dompdf_test extends CI_Controller {
public function index() {
// Load all views as normal
//$this->load->view('phptopdfexample');
$this->all_movements();
// Get output html
$html = $this->output->get_output();
// Load library
$this->load->library('dompdf_gen');
// Convert to PDF
$this->dompdf->load_html($html);
$this->dompdf->render();
$min = 1;
$max = 1000;
$name = rand($min, $max);
$this->dompdf->stream($name . '.pdf');
}
public function all_movements() {
$data['stocks'] = $this->inventory->getdepartmentalmovements();
$data['meds'] = $this->inventory->get_meds();
$this->load->view('deptartmental_issue_pdf', $data);
}
}
當我運行腳本時,我收到內部服務器錯誤,並出現以下錯誤:遇到PHP錯誤
嚴重性:警告
消息:非法字符串偏移'hex'
文件名:include / style.cls.php
行號:1422
我怎么解決這個問題?
這個問題在dompdf 0.6中得到修復
或者您可以通過添加以下條件來糾正它:
DOMPDF /包括/ style.cls.php
然后搜索if(is_null($ col))(可能是:1422行或其附近)
if ( is_null($col) )
$col = self::$_defaults["color"];
//see __set and __get, on all assignments clear cache, not needed on direct set through __set
$this->_prop_cache["color"] = null;
$this->_props["color"] = $col["hex"];
}
也添加這個條件,並嘗試。
if (is_array($col))
$this->_props["color"] = $col["hex"];
步驟1:從“ https://github.com/dompdf/dompdf/releases ”下載Dompdf庫。
第2步:將其粘貼到庫文件夾中,如“\\ xamppp \\ htdocs \\ codeigiter \\ application \\ libraries”。
步驟3:還在庫文件夾中創建一個名為“Pdf.php”的文件,並將代碼粘貼到其中。
require 'dompdf/autoload.inc.php';
use Dompdf\Dompdf;
class Pdf extends Dompdf
{
public function __construct()
{
parent::__construct();
$dompdf = new Dompdf();
}
}
?>
第4步:創建pdf控制器並粘貼下面的代碼並運行控制器。
<?php defined('BASEPATH') OR exit('No direct script access allowed');
class Printbill extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->library('pdf');
}
public function index()
{
$this->load->library('pdf');
$this->pdf->loadHtml('html code or variable');
// $customPaper = array(0,0,570,570);
//$this->pdf->set_paper($customPaper);
$this->pdf->setPaper('A4','portrait');//landscape
$this->pdf->render();
$this->pdf->stream("abc.pdf", array('Attachment'=>0));
//'Attachment'=>0 for view and 'Attachment'=>1 for download file
}
}
?>
