dompdf : HTML to PDF Converter in PHP

Recently, there was an requirement in a project to convert HTML to PDF at run time. While I was going through google, found two very good libraries named 'wkhtmltopdf' and 'dompdf'. dompdf was fulfilling my criteria so i went with that only. Just sharing that with you.

dompdf is an HTML to PDF converter library. At its heart, dompdf is (mostly) CSS2.1 compliant HTML layout and rendering engine written in PHP. It is a style-driven renderer: it will download and read external stylesheets, inline style tags, and the style attributes of individual HTML elements. It also supports most presentational HTML attributes.

Download dompdf library from here.

Recommended Version : 0.6.0_beta3

Requirements : 

1)       PHP 5.0+ (5.3 recommended)
2)      MBString extension - for better Unicode support.
3)      DOM extension (bundled with PHP 5) –“The DOM extension allows you to operate on XML documents through the DOM API with PHP 5.” 

Pros: 

1)      Easy to Use.
2)      Well Documented.
3)      Better CSS support except few things like ‘css : float’ property.

Cons(Known Issues) :  

1)       Not particularly tolerant to poorly-formed HTML input (using Tidy first may help).
2)       Large files or large tables can take a while to render.
3)       CSS float is not supported.

How To Use : 

Following is a simple example to show use of dompdf library.

test.php


<?php

require_once("../dompdf_config.inc.php");
$html = '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Table</title>
<style>
body{
                font-family:Arial, Helvetica, sans-serif;
                font-size:12px;
}

table tr th{
    text-align:left;
    vertical-align:top;
}

.italic_text{
    font-style:italic;
    font-size:12px;
    line-height:14px !important;
}

div{
            text-align:center;
}

</style>
</head>
<body>
            <div><h1>Test Document</h1></div>

            <table cellspacing="0" cellpadding="0" border="0">
            <tr>
                        <td class="italic_text"><h3>DirtyhandsPHP</h3></td>
            </tr>
            </table>
</body>
</html>';


if ( get_magic_quotes_gpc() )
               $str = stripslashes($str);

$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->set_paper('letter', 'landscape');
$dompdf->render();

//Set Attachment attribute as True to show download file dialog box
$dompdf->stream("dompdf_out.pdf", array("Attachment" => false));

//For Attachment to sent in email
//$output = $dompdf->output();

exit(0);

?>

Thanks!!!!!!!!!! Enjoy Programming :)

Odoo: Qweb Templates Cache Issue

Hi Everyone, Today I was working on a hotel booking template in Odoo and changes made in the Qweb template(.xml) were not reflecting on updating module with odoo service restart. Tried few times without any success :(. Finally, I decided to delete the old template from Odoo backend and then update module again and it worked like a charm!! :) Steps to delete template from backend: Settings --> User Interface --> Views --> Search by template name Delete the used template. Although it's a small post, but I'm sure it will meet the purpose and help someone in the future. Thanks!!!

Odoo/OpenERP: one2one relational field example

one2one relational field is deprecated in OpenERP version>5 but you can achieve the same using many2one relational field. You can achieve it in following two ways : 1) using many2one field in both the objects ( http://tutorialopenerp.wordpress.com/2014/04/23/one2one/ ) 2)  using inheritance by deligation You can easily find the first solution with little search over internet so let's start with 2nd solution. Scenario :  I want to create a one2one relation between two objects of openerp hr.employee and hr.employee.medical.details What I should do  i. Add _inherits section in hr_employee class ii. Add field medical_detail_id in hr_employee class class hr_employee(osv.osv):     _name = 'hr.employee'     _inherits = {' hr.employee.medical.details ': "medical_detail_id"}     _inherit = 'hr.employee'         _columns = {              'emp_code':fields.char('Employee Code', si
