codeigniter tutorial pdf to create your reports.
UPDATE : Add MPDF 6 And Arabic Support 10/2017
From time to another with working as Web Developer Freelancer many clients want to add reports to their websites. And after many experiments I chose MPDF.
MPDF. is my best favorite library to deal with PDF reports files by PHP and in the following lines, I will explain why ?
1- MPDF Has Good performance, so you don’t wait for a long time to render your report, this is will be so important if you work with big retrieved data from the database.
2- MPDF reduce PDF files size. so again don’t worry about you data size.
3- MPDF Support many languages .and works without problems with RTL languages like Arabic,
4- MPDF Support CSS and improved to support css3 syntax, so you can design your beautiful report and let MPDF library convert it easily.
5- MPDF Support external TTF fonts ,just choose your favorite font and it will deal with
6- MPDF has well organized and clear documentation, user guide have many examples for every single code.
7- MPDF improved faster and it is free. So how to integrate this library with Codeigniter ?
Step one :
Download MPDF library and extract files in third_party directory
Step two :
Create new pdf.php file in libraries and put this code on it
class pdf {
function pdf()
{
$CI = & get_instance();
log_message('Debug', 'mPDF class is loaded.');
}
function load($param=NULL)
{
include_once APPPATH.'/third_party/mpdf/mpdf.php';
$param = "'','', 0, '', 0, 0, 0, 0, 0, 0";
return new mPDF($param);
}
}
Step three :
Create new controller and put this function on it
function print_item()
{
// load library
$this->load->library('pdf');
$pdf = $this->pdf->load();
// retrieve data from model
$data['all_itemreport'] = $this->itemreport->get_items();
$data['title'] = "items";
ini_set('memory_limit', '256M');
// boost the memory limit if it's low ;)
$html = $this->load->view('itemreport/plist_item', $data, true);
// render the view into HTML
$pdf->WriteHTML($html); // write the HTML into the PDF
$output = 'itemreport' . date('Y_m_d_H_i_s') . '_.pdf';
$pdf->Output("$output", 'I'); // save to file because we can
exit();
}
Step four :
Create new model and put this function to select data from database
function get_items()
{
$this->db->order_by("it_created", "asc");
$result = $this->db->get("d_items");
return $result->result_array();
}
Step five :
Create new view file to load HTML report and put table.
<h2>News Table</h2>
<div class="alert alert-info">
<strong>Demo Test!</strong>
You can test MPDF library in this demo with latest version</div>
<p></p>
<div class="table-responsive">
<table class="table">
<thead>
<tr>
<th>Title</th>
<th>Desc</th>
<th>Image</th>
</tr>
</thead>
<tbody>
<?php foreach ($news as $n) : ?>
<tr>
<td><?= $n['ne_title']; ?></td>
<td><?= $n['ne_desc']; ?></td>
<td><img src="<?php echo base_url(); ?>global/uploads/<?= $n['ne_img']; ?>"/>
</td>
</tr>
</tbody>
<?php endforeach ?>
</table>
</div>
Additional options :
to support arabic or any utf-8 languages add these three lines to step three (TESTED ON Version 6 only )
$pdf->allow_charset_conversion=true; // Set by default to TRUE
$pdf->charset_in='UTF-8';
$pdf->SetDirectionality('rtl');
$pdf->autoLangToFont = true;
then add your lang code to the html tag as example for arabic language add ar
<html lang="ar">
