在下面的codeigniter代码中，我想创建一个pdf文件，但它显示网页。我从这个网站 http://blog.luutaa.com/php/generating-a-pdf-using-codeigniter/下载教程 和我创建助手并创建 mpdf 文件夹并将所有提取的文件放入其中并放置 pdf 的控制器代码。但问题没有解决。
控制器：
<?php
class Help extends ci_controller
{
function index()
{
$this->load->view('help_view');
}
//to create the data and insetin to the coursesubject table
public function pdf_report(){
$this->load->helper(array('My_Pdf')); // Load helper
$data = file_get_contents(site_url('http://localhost/seatingreport4/index.php/help')); // Pass the url of html report
create_pdf($data); //Create pdf
}
}
?>
看法：
<!DOCTYPE html>
<html>
<head>
<?php include_once('header2.php'); ?>
<div id="showhide">
<?php include_once('menu.php'); ?>
</div>
<a id="toggle" onClick="showorhide('showhide')"><img src="<?php echo base_url('img/m.jpg'); ?>" HEIGHT="40" WIDTH="40" BORDER="0" alt="logo"style="margin-bottom:7px; margin-top:7px;" /></a></a>
