I am using dompdf php lib for generating pdf.
Right now it ask user to save the file in their machine.
Code i tried so far:
<?php
$dompdf = new Dompdf();
$dompdf->loadHtml($html);
$dompdf->render();
$dompdf->stream($filename.'.pdf');
$output = $dompdf->output();
file_put_contents($filename.'.pdf', $output);
?>
Give "write" permission to the directory you need to put the file.
I switched from TCPDF to domPDF because it seems more convenient to handle when creating invoices from html to pdf (I am rather a low pro on PHP :)). Now that I created the html file as a PDF file I recognized it does not output any PHP in the PDF - since the data from my sql databanks should fill the PDF it is kinda a problem.
I saw that you can enable PHP in the options.php included in the src-folder and I tried to do like it is written in the manual (and also tried various other code lines) but it just doesn't want to work:
$root = realpath($_SERVER["DOCUMENT_ROOT"]);
require_once ("$root/../xxx/dompdf/autoload.inc.php");
use Dompdf\Dompdf;
use Dompdf\Options;
$options = new Options();
$options->setIsPhpEnabled('true');
$dompdf = new Dompdf($options);
$dompdf->loadHtml(file_get_contents("testdomhtml.php"));
$dompdf->setPaper('A4', 'portrait');
$dompdf->render();
$dompdf->stream("bla",array("Attachment"=>0));
The PDF is shown but without the input from any PHP code.
If someone would be so kind, I would also be interested in knowing why and in how far enabling PHP is a security risk since I actually want to use that for my business. Would it be more advisable to wrap it all up in the main php file without loading external html and css files?
Thanks a lot in advance!
You could do something like this (not tested the code). Replace
$dompdf->loadHtml(file_get_contents("testdomhtml.php"));
With
ob_start();
include 'testdomhtml.php';
$output = ob_get_clean();
$dompdf->loadHtml($output);
More options How to execute and get content of a .php file in a variable?
Your file_get_contents("testdomhtml.php") will get actual content of file and will not execute any code inside it. Instead make it web accessible and pass URL to this page:
$dompdf->load_html_file('http://yourdomain.ext/testdomhtml.php');
I want to use dompdf in my php website and I try to include the library without Composer and I can not get it to work.
The code I try to test is:
<?php
include "../../plugins/dompdf/Autoloader.php";
$dompdf = new Dompdf();
$dompdf->loadHtml('hello world');
// (Optional) Setup the paper size and orientation
$dompdf->setPaper('A4', 'landscape');
// Render the HTML as PDF
$dompdf->render();
?>
But i get the error:
Fatal error: Class 'Dompdf' not found ...
Can anyone explain me how to include the library without install composer in the server?
Thank You.
With the right include is working like a charm, as said Samrap i was including the wrong file.
Now the code is:
<?php
//Configure the directory where you have the dompdf
require_once "../../plugins/dompdf/autoload.inc.php";
use Dompdf\Dompdf;
//$dompdf = new dompdf();
//$dompdf = new DOMPDF();
$dompdf = new Dompdf();
$dompdf->loadHtml('hello world');
// (Optional) Setup the paper size and orientation
$dompdf->setPaper('A4', 'landscape');
// Render the HTML as PDF
$dompdf->render();
// Output the generated PDF to Browser
$dompdf->stream();
?>
Thank you Samrap for your help.
You're requiring the wrong autoload file. The docs clearly state to include this file for autoloading:
require_once 'dompdf/autoload.inc.php';
If you look at that file, you'll see it does require Autoloader.php but performs a few other bootstrapping tasks as well.
require_once("function/dompdf/dompdf_config.inc.php");
$dompdf = new DOMPDF();
foreach($modules as $module){
$output = "Hello " .$module['name'];
$dompdf->load_html($output);
$dompdf->render();
$output_pdf = $dompdf->output();
file_put_contents($dir . $name_modulo . ".pdf", $output_pdf);
}
Fatal error: Uncaught exception 'DOMPDF_Exception' with message 'No block-level parent found. Not good.'
Late to this thread, but based on the post at https://github.com/dompdf/dompdf/issues/902, I was able to fix this issue by removing spaces between <html><head>, </head><body>, and </body></html>
So, instead of having properly formated html code like this:
<html>
<head>
...
</head>
<body>
...
</body>
</html>
I deleted all the new lines or spaces between the tags, now it looks like this :
<html><head>
...
</head><body>
...
</body></html>
And everything is hunky-dory again
dompdf folder > dompdf_config.custom.inc.php file > try to uncomment the line
define("DOMPDF_ENABLE_HTML5PARSER", true);
Also replace unsupported html5 tags & attributes with supported one, clear html errors for better result
Just define
$dompdf->set_option('enable_html5_parser', TRUE);
I think it will fix the issue.
Or can edit the dompdf/dompdf_config.inc.php file
go to line no 322
change
def("DOMPDF_ENABLE_HTML5PARSER", false);
to
def("DOMPDF_ENABLE_HTML5PARSER", true);
go to configuration file dompdf_config.custom.inc.php and uncomment define("DOMPDF_ENABLE_HTML5PARSER", true); and check, basically it requires html5 parser enabled in your configuration file.
Just uncomment define("DOMPDF_ENABLE_HTML5PARSER", true); this line from dompdf_config.custom.inc.php this file.
You can find this file for codeigniter in vendor/dompdf/dompdf this directory.
If you have installed dompdf using composer require then defining the enable_html5_parser option using the set_option method works well if you don't want to modify the vendor folder
So add the following to each document that is creating an error
$dompdf->set_option('enable_html5_parser', TRUE);
For newer versions of Dompdf you can use this to enable the HTML5 parser:
use Dompdf\Options;
$options = new Options();
$options->set('isHtml5ParserEnabled', true);
$dompdf = new Dompdf($options);
I don't know why the answer regarding ("DOMPDF_ENABLE_HTML5PARSER", true) was voted down either. Because I spent over 30 hours trying to figure out why this was happening in my website, until I came across this solution. So I enabled the "DOMPDF_ENABLE_HTML5PARSER" by setting it to "TRUE" as noted above. And immediately the error regarding "No block-level parent found" was resolved and my scripts worked. Maybe the 2nd answer was voted down because it duplicated a previous answer (but cut a guy a break, why don't you? Maybe he didn't see it..). Or maybe the "downvoter" has an attitude problem.
I had the same problem with domPDF 0.8.3 on PHP 5.6 and I couldn't find neither dompdf_config.custom.inc.php nor dompdf_config.inc.php and didn´t work either; to solve my problem, I added body {display:block;} to my CSS and had not further problem.
I tried locating the white space or other spaces. didn't succeed, so
I just Minimized the HTML file that is a PDF template
it removed all the spaces, white spaces, etc
worked for me
You can enable the HTML5 parser as mentioned above or you can update the dompdf library. I found updating the dompdf library from 6.2 to 8.2 got past this error BUT if you are using Drupal like I am there's a little bit of trickery you have to do to get Drupal to recognize the newer version of the library (see here: https://www.drupal.org/project/print/issues/3010637 )
In my case, it is a bit different.
The pdf creation code was in the loop but the dom pdf object creation was above the loop. So when it is trying to create the pdf for the second time, I had seen the above error. To resolve it, each and every time I am creating a new object and it worked as expected.
Example:
(Code not working)
//Reference of Dompdf namespace
use Dompdf\Dompdf;
use Dompdf\Options;
//instantiate and use the Options class
$options = new Options();
$options->set('enable_html5_parser', true);
$dompdf = new Dompdf($options);
for($i = 0; $i < $count; $i++) {
//Create PDF
$dompdf->loadHtml($form_data);
$dompdf->setPaper('A4', 'landscape');
$dompdf->render();
$output = $dompdf->output();
file_put_contents($pdf_file_name, $output);
}
Working Code:
//Reference of Dompdf namespace
use Dompdf\Dompdf;
use Dompdf\Options;
//instantiate and use the Options class
$options = new Options();
$options->set('enable_html5_parser', true);
for($i = 0; $i < $count; $i++) {
$dompdf = new Dompdf($options);
//Create PDF
$dompdf->loadHtml($form_data);
$dompdf->setPaper('A4', 'landscape');
$dompdf->render();
$output = $dompdf->output();
file_put_contents($pdf_file_name, $output);
}
I would like to call a php file inside the controller, but it appears an error like this:
Fatal error: Class 'AppBundle\Controller\DOMPDF' not found in ....
Here my code :
require_once(__DIR__.'/../../../../dompdf/dompdf_config.inc.php');
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
$dompdf->stream('report_'.$name.'.pdf');
If anyone can help me? thanks
For utilize the DOMPDF PHP Library in a symfony2 project you can use the DompdfBundle. Following the instruction in the github page.
After the installation, you can use it as a service, as described in the doc:
$dompdf = $this->get('slik_dompdf');
// Generate the pdf
$dompdf->getpdf($html);
// Either stream the pdf to the browser
$dompdf->stream('report_'.$name.'.pdf');
Hope this help
