I have a file that pulls some information from the database and creates some relatively simple dynamic HTML.
The file can then be used by DOMPDF to turn it into a PDF document. DOMDPF uses GET variables to achieve the basic implementation.
ob_start();
include_once("report.php?id=1249642977");
require_once("dompdf/dompdf_config.inc.php");
$dompdf = new DOMPDF();
$dompdf->load_html(ob_get_contents());
$dompdf->render();
$dompdf->stream("sample.pdf", array('Attachment'=>'0'));
ob_end_clean();
I thought I might be able to use something ilke that to achieve the aim but unsurprisingly it didn't work.
So how can I read the HTML that gets output to the browser if you were to load the file directly, into a string for use with the DOMPDF class?
Two problems.
First, you can't call a PHP page like that using include_once - the query string will be ignored. You have to give the id to report.php some other way.
Second, you're correctly buffering the output. However, you're passing the current output buffer to DOMPDF, telling it to generate a PDF to the output buffer, and the discarding the output buffer. You probably want something like:
$dompdf = new DOMPDF();
$dompdf->load_html(ob_get_clean());
$dompdf->render();
$dompdf->stream("sample.pdf", array('Attachment'=>'0'));
That'll get the current output buffer, discard it, and disable output buffering. The $dompdf->stream should then work.
What about using a simple HTTP request to get the HTML file and than loading it in the $dompdf object:
<?php
//...
$dompdf->load_html(file_get_contents("http://yoursite.net/report.php?id=1249642977"));
//...
?>
I don't see why you need output buffering here..
BlackAura is on the right track. File_get_contents, as others have suggested will not pass along the GET vars (or POST). But you can use cURL to do that. The code below should work:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://YOURFULLURL.COM/report.php?id=1249642977');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$my_html = curl_exec($ch);
curl_close($ch);
$dompdf = new DOMPDF();
$dompdf->load_html($my_html);
$dompdf->render();
$dompdf->stream("sample.pdf", array('Attachment'=>'0'));
Hope that helps.

Simply use PHP's file_get_contents as such:
$page_html = file_get_contents("page.php?id=number");
then pass $page_html to dompdf.
Hope this helps :)
I eventually decided to alter the php page that produces the HTML so that it becomes a function returning an HTML string. This is more of a workaround than a solution.
Future Googlers to this page should be aware that DOMPDF allows you to run inline PHP on a page using:
<script type="text/php">
//some PHP here
</script>
BlackAura has the right idea. You're appending the generated PDF to the output buffer, and then discarding everything.

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'm trying to save the content of a file into a PDF using html2pdf, but the file has some PHP codes which need to be processed. I made some research and I found out that I had to use output buffering so that the PHP content in the file can be processed. So I did something like:
<?php
require_once('html2pdf.class.php');
ob_start();
require_once('my_file.php');
$content = ob_get_clean();
// force download of $content to a PDF
$html2pdf = new HTML2PDF('P','A3','fr', false, 'ISO-8859-1');
$html2pdf->writeHTML($content);
$html2pdf->Output('file_name.pdf', 'D');
?>
The file my_file.php is the file that has some PHP code and the HTML content that I wanna save to a PDF, and the variable $content is the actual content with the PHP codes processed and everything. This works fine on Apache, but not on IIS.
Does anybody know an alternative way to make this work witout using ouput buffering? I tried file_get_contents('my_file.php'); but my php contents in my_file.php do not get processed when I do so.
Please, I'm looking for ways to do this without output buffering so that it can work on any server. I'm not looking for answers telling me to change my IIS server configuration or to use something else other than html2pdf.
Thanks in advance for any help
If you can modify the contents of my_file.php, you can put all the text into a variable there instead of outputting it directly.
You can use PHP/PDF Library http://php.net/manual/en/book.pdf.php
And follow this example : http://php.net/manual/en/pdf.examples-basic.php
Hope that helps :)
The easiest approach would be to edit my_file.php so that rather than containing HTML it assigns the HTML content to a PHP variable. Then all you need to do is echo the variable.
//other PHP processing goes here, or anywhere else.
$someVar = "hello world";
$myHTML = "<html>My output: $someVar </html>";
echo $myHTML;
It's an ugly way of handling HTML output, and I'm not saying it's good programming, but if you want to avoid editing config files it would be quick and easy.
I have a page that uses the glob function and file_get_contents to have a few html files and store them in the buffer.
So I want to convert this buffer ob_get_contents() to an pdf file.
What is the best way to do that? how?
Thanks in advance.
For creating PDF files from HTML and CSS, check out DOMpdf.
While this solution doesn't support the full range of HTML and CSS and its rendering can be a pain sometimes, it has one advantage: it does not require any special binaries to be installed (like wkhtmltopdf). It should run on your average shared PHP hosting.
Usage example:
<?php
require_once("dompdf_config.inc.php");
$html =
'<html><body>'.
'<p>Put your html here, or generate it with your favourite '.
'templating system.</p>'.
'</body></html>';
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
$dompdf->stream("sample.pdf");
?>
why using the outputbuffer for this? you have it in variables using file_get_contents and can simply create your pdf with the data from the variables. when using ob_get_contents all it does is return the outputbuffer and what you normally do with the result is saving into a variable...
btw. you do want to convert html into pdf? If yes have a look at wkhtmltopdf
If ob_get_contents contains html files they are so many solutions out there that can achieve what you want. I think you should look at the following
PrinceXML
FPDF
TCPDF
HTML to PDF converter (PHP5)
wkhtmltopdf
Example using Simple HTML 2 PDF using PHP
$html = ob_get_contents();
ob_end_clean();
$pdf = new HTML2FPDF();
$pdf->SetTopMargin(1);
$pdf->AddPage();
$pdf->WriteHTML($html);
$pdf->Output('test.pdf','D');
After creating a PDF file in PHP Using DOMPDF, I need to redirect user to different page.
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
$dompdf->stream($fileName . '.pdf', array("Attachment" => 0));
header('location:newpage.php');
This code creates the PDF file but does not redirect. How can I fix this problem?
Note : This is my previous question. Still I'm trying to get this fixed, still no luck.
The $dompdf->stream() call starts outputting data to the client. Once content is being sent, it is impossible to modify the headers, and thus perform the redirection you want. You can see this by turning on the warnings in PHP (error_reporting).
A way to do this is to open a new window, but it requires Javascript.
function downloadPDF(){
window.open("get-pdf.php?id=12345");
location.href = "newpage.php";
}
I try to convert dynamic php database file to pdf.
I try with DOMPDF, but I have a problem with defining the string. I'll explain:
Here is a 'hello world' script for dompdf:
require_once("dompdf_config.inc.php");
$html =
'<html><body>'.
'<p>Hello World!</p>'.
'</body></html>';
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
$dompdf->stream("hello_world.pdf");
The thing is that instead of a simple
'<html><body>'.
'<p>Hello World!</p>'.
'</body></html>'
I have a long php file full of functions and sql queries. because of it I have inside it many ",',; e.t.c signs. I also have a javascript dynamic chart (jqplot) in this page.
So instead of pdf file I get errors errors errors...
Does anyone has a solution for this?
I will really appreciate any answer, and will be really really thankful for a solution...
First you'll need to generate HTML from your PHP, then pass it to DOMPDF:
<?php
require_once("dompdf_config.inc.php");
ob_start();
require_once("path/to/input/file.php");
$dompdf = new DOMPDF();
$dompdf->load_html(ob_get_clean());
$dompdf->render();
$dompdf->stream("file.pdf");
?>
You can also do a regular HTTP request:
<?php
require_once("dompdf_config.inc.php");
$dompdf = new DOMPDF();
$dompdf->load_html_file('http://example.com/file.php');
$dompdf->render();
$dompdf->stream("file.pdf");
?>
If you need JavaScript support, try wkhtmltopdf, it's based on Webkit and does it's work perfectly.
You can use ob_start and ob_get_contents to run PHP code and capture the output as a string.
For the JavaScript chart, though, you're out of luck. DOMPDF is pretty smart, but it's not that smart. You'll need to either use a non-JavaScript chart solution, do without the charts, or use a web browser to generate the PDF.
I am not sure why you need to generate HTML to build a PDF in the first place but as others have suggested, build out your PHP script and then use something like FPDF or TCPDF.
They both build PDFs just fine and can take HTML input.
Try This ...
<?php
ob_start();
require_once("dompdf_config.inc.php");
$file = file_get_contents('http://example.com/file.php');
$dompdf = new DOMPDF();
$dompdf->load_html($file);
$dompdf->render();
$dompdf->stream("filename.pdf");
?>
