我是 Codeigniter 的新手,想使用 MPDF 将 MYSQL 数据库中的数据导出到 PDF 文件中。代码如下:
看法:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Export PDF</title>
</head>
<body>
<div id="container">
<h4>Member Data</h4>
<table border="1">
<tr>
<th>group_id</th>
<th>group_name</th>
<th>Archieved</th>
</tr>
<?php
foreach ($member as $rows) {
echo $rows['group_id'];
?>
<tr>
<td><?php echo $rows['group_id'] ?></td>
<td><?php echo $rows['group_name']?></td>
<td><?php echo $rows['archieved'] ?></td>
</tr>
<?php
$i++;
}
?>
</table>
<br> <br>
<a href='<?php echo base_url(); ?>index.php/member_con/topdf'><span style='color:green;'>Export to Pdf</span></a>
</div>
<?php
?>
</body>
</html>
控制器:
<?php
class Member_con extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->model('member_model');
$this->load->helper('url');
$this->load->library('mpdf');
}
public function index() {
$data['member'] = $this->member_model->alldata();
$this->load->view('member_view', $data);
}
function topdf() {
$this->mpdf->useOnlyCoreFonts = true;
$filename = "VISH";
$data['member'] = $this->member_model->alldata();
$html = $this->load->view('member_view', $data['member'], true);
$this->mpdf->setTitle('Posts');
$this->mpdf->writeHTML($html);
$this->mpdf->output($filename, 'D');
}
}
?>
模型:
<?php
class Member_model extends CI_Model {
function __construct() {
parent::__construct();
$this->load->database();
}
function Member_Model() {
parent::Model();
}
function alldata()
{
$this->db->select('*');
$this->db->from('groups');
$this->db->order_by('group_id','ASC');
$getData = $this->db->get();
if($getData->num_rows() > 0)
return $getData->result_array();
else return null;
}
}
?>
使用此代码,它给了我一个空白的 PDF 文件,只有文本为“成员数据”和“导出为 pdf”。我检查了它是否正在将数据传递给查看,是的,它正在这样做。但不知道'foreach'循环是怎么回事。我正在打印“foreach”循环之外的所有内容,但对数据成员进行了机器人操作。谁能让我知道我该怎么办?
提前致谢....
