Dompdf Save To Directory
in various fora; some have been solved, some not. I checked plenty of resources, but my issue could not be resolved. I am generating php page using smarty template based on html form input and uploaded files. Using dompdf, I want to save the generated page as a pdf file. When the user submits the multipart/form-data, data is posted to itself. Then it undergoes validation process. When all is fine, a new page is dompdf output to browser generated using a template file. There is no output, instead, dompdf utilizes the template file to stream the pdf file. After solving several stages of problems such as "DOMPDF not found", insufficient memory etc, I am now stuck with "Unable to stream pdf: headers already sent" error. One of the most common problems is presence of line break, white space or any output being before stream() is called. I checked for white space before and after ?. There are nor print_f or echo statements either. How can I troubleshoot this problem? Where does the problem lie...in the smarty template file or the php file itself? Here is the code: require_once("dompdf/dompdf_config.inc.php"); spl_autoload_register('DOMPDF_autoload'); $html = $smarty->fetch('index.tpl'); $dompdf = new DOMPDF(); $dompdf->load_html($html); $dompdf->set_paper('a4', 'portrait'); $dompdf->render(); $dompdf->stream("newfile.pdf"); php smarty dompdf share|improve this question edited Oct 22 '13 at 18:00 asked Oct 22 '13 at 17:39 sridhar 3031311 show your code. –user2092317 Oct 22 '13 at 17:46 Check that dompdf itself (or smarty) aren't doing some hidden output. e.g. comment out the $dompdf-stream() call, hit the url, and save the contents... see what's in there. –Marc B Oct 22 '13 at 18:04 which smarty version are you using? In some old versions there was a problem of smarty adding spaces at the beginning of the compiled file –Borgtex Oct 23

PhenX closed this Dec 6, 2012 dompdf member PhenX commented Dec 6, 2012 From eclecticgeek on December 14, 2009 18:29:41 Right now this doesn't necessarily look like an issue with DOMPDF. The "headers already sent" message is due to the fact that some content has already been sent to the web browser. As a result DOMPDF is unable to set the mime type of the content. If you're not receiving any error messages when debugging is disabled, and you're not sending any other content to the web browser, then one of the files involved in creating the PDF might have some empty lines. Check your files to ensure that there are no extra line breaks outside the PHP code. If it's not in your files, then one of the DOMPDF files could have been modified on upload.
