For some reason, the background image doesn't show no matter what I try. I've put the direct url as well. None of them worked. Can someone with dompdf experience tell me what I need to do? It's important to note that other images appear just fine. It's only the bakground images that are causing issues. Here is one of the background images:
body{ font-size:15px; background:url(bg.jpg) repeat-x bottom left; }
It looks like DOMPDF supports background images, so I have to assume that the filepath is wrong.
If you add <img src="bg.jpg" alt="" /> does it work?
I've found in the last project I used DOMPDF I needed to point the image file to it on the filesystem (not a relative path to webroot), and I had to use a root path that ended up looking like this
<img src="<?php echo DOCROOT; ?>assets/images/bg.jpg" alt="" />
Where DOCROOT became /users/me/public_html/. To test it as plain HTML before I sent to DOMPDF, I did a str_replace() to change the DOCROOT to / (relative to my path).
Using DOMODF 0.5.1? It's probably having trouble parsing the background shorthand. You could try breaking up the generic background property into the specific properties:
background-image: url(bg.jpg);
background-repeat: repeat-x;
background-position: bottom left;
I also found that sometimes I had to supply a full URL (http://example.com/bg.jpg).
The handling of this property is a little buggy in that version of DOMPDF. You might consider upgrading to the 0.6.0 code base (currently at beta 1). It has a number of improvements over the previous release.
