Q: How do I save a PDF to disk?

A: If you are using the included dompdf.php script you can pass it the "save_file" option in conjunction with the "output_file" option.

If you are using the DOMPDF class, you can save the generated PDF by calling:

Note that typically dompdf->stream() and dompdf->output() are mutually exclusive.

Q: I have a big table and it's broken!

A: This is fixed in versions 0.4 and higher. Previous versions did not support tables that spanned pages.

Q: Is there a way to add headers and footers or page numbers?

A: Yes, you can add headers and footers using inline PHP. Headers and footers are added by accessing the PDF renderer directly using inline PHP embedded in your HTML file. This is similar to creating PDFs with FPDF or ezPDF from R&OS, in that you can draw lines, boxes and text directly on the PDF. Here are step by step instructions:

Somewhere in your html file, near the top, open a script tag with a "text/php" type: <script type="text/php"> Check if the $pdf variable is set. dompdf sets this variable when evaluating embedded PHP. Pick a font: Use the CPDF_Adapter::page_text() method to set text that will be displayed on every page:

In this example, the text will be displayed 72pt (1 in) from the left edge of the page and 18pt (1/4 in) from the top of the page, in 6pt font. and are automatically replaced by dompdf to the appropriate values on each page. The last argument to page_text() is the colour which takes an array of the form array(r,g,b) where each of r, g, and b are between 0.0 and 1.0.

There are several other methods available. See the API documentation for the CPDF_Adapter class ( ) for more details. Also have a look at the demo_01.html file in the www/test/ directory. It adds a header and footer using PDF_Adapter->page_text(). It also adds text superimposed over the rendered text using a PDF 'object'. This object is added using CPDF_Adapter->add_object(). See Usage for more info on inline PHP.

Q: How can I add an image to a header or footer on every page?

A: You can add images and shapes (line, rectangles, etc.) to every page using PDF 'objects'. A PDF object captures all rendering commands as a sort of template that can then be added to multiple pages:

Q: How do I insert page breaks?

A: Page breaks can be inserted by applying the CSS properties page-break-before and page-break-after to any block level element.

Q: How can I make PDFs open in the browser window instead of opening the download dialog?


How do I centre a table, paragraph or div?

Q: How can I print the euro symbol?

A: You can print the euro symbol (€) using the following entity: &#0128; .

Q: I'm getting the following error:

Parse error: parse error, unexpected T_NEW in /var/www/dompdf/include/ on line 240

A: Any parse error generated by dompdf is caused by trying to run dompdf under PHP4. dompdf only works under PHP 5 and there are no plans for a PHP 4 port. If you can run dompdf on your home machine, but not on your web host, confirm which version of PHP is running on your web host via phpinfo().

Some web hosts have both PHP 4 and PHP 5 installed. Check with your webhost how to enable PHP 5.

Q: I'm getting the following error:

Cannot access undefined property for object with overloaded property access in /var/www/dompdf/include/frame_tree.cls.php on line 160

A: This error is caused by an incompatibility with the Zend Optimizer. Disable the optimizer when using dompdf.

Q: I'm getting the following error:

Fatal error: DOMPDF_autoload() [function.require]. Failed opening required '/var/www/dompdf/include/domdocument.cls.php' (include_path='.:') in /var/www/dompdf/ on line 146

A: This error occurs when the version of PHP that you are using does not have the DOM extension enabled. You can check which extensions are enabled by examining the output of phpinfo().

There are a couple of ways that the DOM extension could have been disabled. DOM uses libxml, so if libxml is not present on your server then the DOM extension will not work. Alternatively, if PHP was compiled with the '--disable-dom' switch or the '--disable-xml' switch, DOM support will also be removed. You can check which switches were used to compile PHP with phpinfo().

Q: I'm getting the following error:

Fatal error: Maximum execution time of 30 seconds exceeded in /var/www/dompdf/dompdf.php on line XXX

A: Nested tables are not supported yet and can cause dompdf to enter an endless loop, thus giving rise to this error.

Q: I'm getting the following error:

Fatal error: Uncaught exception 'DOMPDF_Exception' with message 'No block-level parent found. Not good.' in C:\Program Files\Apache\htdocs\dompdf\include\inline_positioner.cls.php:68

A: This should be fixed in versions 0.4.1 and up. The error was caused by parse_url() thinking that the 'c' in 'c:\' was a protocol. Version 0.4.1 works around this issue.

A: Another possible issue is caused by files not uploading correctly. Try reuploading the files.

Q: I set the DOMPDF_ENABLE_REMOTE configuration constant to true and remote stylesheet and/or images still don't work, what am I missing?

A: The problem may come from a bad configuration of your PHP installation. The allow_url_fopen configuration variable needs to be set to 1 or On in your php.ini file (which is the default value).
