Please help on this issue http://stackoverflow.com/questions/38131897/dompdf-error-unable-to-stream-pdf-headers-already-sent that how can I redirect ? All your help will be highly appreciated.

Do you get an error message? sanjay_tank1975 2015-01-07 13:08:57 UTC #3 No error message..it generates the pdf file and saves it to download folder, But doesn't redirect to the specified page. droopsnoot 2015-01-07 19:02:01 UTC #4 Have you enabled PHP error reporting? If you try to redirect to a different page, does it make any difference? I've read in some places you have to specify the complete url, not just the page - does that make any difference? Mittineague 2015-01-07 19:07:04 UTC #5 droopsnoot: Have you enabled PHP error reporting? My guess is Not. That code looks like it would throw a "Headers already sent" error sanjay_tank1975 2015-01-08 07:56:57 UTC #6 This error is being shown - Deprecated: Function set_magic_quotes_runtime() is deprecated in C:\xampp\htdocs\shopping\admin\dompdf\lib\class.pdf.php on line 4332 Deprecated: Function set_magic_quotes_runtime() is deprecated in C:\xampp\htdocs\sh

Here's the error: (I'm already sent not sure which source file this comes from) DOMDocument::loadHTML(): htmlParseEntityRef: no name in Entity, line: 146 DOMDocument::loadHTML(): htmlParseEntityRef: no name in Entity, line: 288 DOMDocument::loadHTML(): htmlParseEntityRef: no name in Entity, line: 288 DOMDocument::loadHTML(): Unexpected end tag : p in Entity, line: 634 Unable to stream pdf: headers already sent I can send a link privately of the generated html just prior to being unable to stream passed into dompdf. This all worked fine on the previous server. It generates a large report of 30 to 40 pages and full of photos. The finished PDF size is usually around 2MB. The PHP code looks like this: require_once("dompdf_060/dompdf_config.inc.php"); $old_limit = ini_set("memory_limit", "1000M"); $dompdf = new DOMPDF(); $dompdf->load_html($html); // loaded from a template, database, external images etc $dompdf->set_paper("A4", "portrait"); $dompdf->render(); $dompdf->stream(htmlspecialchars_decode($customer_name).'.pdf'); thanks, Steve dompdf member bsweeney commented Apr 1, 2015 The issue may have been present on the other server, but you might not have noticed. These are notices and as such don't affect the ability of dompdf to continue processing. The PDF is created, just not streamable because of the notice text already sent to the browser (as evidenced by the "Unable to stream pdf: headers already sent" text. Your previous server may have suppressed notices or disabled sending that content to the browser (which is recommended). So you can either: Run your html through a validator and correct any issues. dompdf is fairly finicky about the HTML syntax. If you're using dompdf 0.6.1 you can try enabling the HTML5 parser.

Warning : Cannot modify header information - headers already sent in drupal_send_headers() (line 1221 in C:\xampp\htdocs\drupal\includes\bootstrap.inc). Actually, I have a link in my initial page (named 'my-account/invoices') which redirects to a PDF page named 'my-account/invoices/%invoice_number'. This last one is loaded by a 'page callback' function : function invoices_callback($var){ require_once('sites/all/libraries/dompdf/dompdf_config.inc.php'); $filename = 'Invoice n°' . $var . '.pdf'; $dompdf = new DOMPDF(); $dompdf->load_html('
Test n° : ' . $var . ''); $dompdf->render(); $dompdf->stream($filename, array('Attachment'=>0)); header('Content-type: application/pdf'); } As you see, I didn't use a pdf module, like printer, which is too heavy. I use a custom module which implement a page callback function, and inside I use dompdf library. The pdf is displayed normally, but when I come back to initial page I have these warnings. I have tried several things: I removed the header function. Effect: the first warning is gone but I still have the second. It seems like the stream method of DOMPDF class wants to sent a header... I have added a charset utf-8 to the header function I used ob_start() and ob_end_flush() functions at the beginning and at the end of the code. Surprisingly doesn't work. I lastly use drupal_add_http_header function. Doesn't remove warnings. What i can
