DomPDF: Image not readable or empty
Following helped me like charm, at least localy, and even with
define("DOMPDF_ENABLE_REMOTE", false);
The solution is to change the image SRC to the absolute path on the server, like this:
<img src="/var/www/domain/images/myimage.jpg" />
All of the following worked for me:
<img src="<?php echo $_SERVER["DOCUMENT_ROOT"].'/placeholder.jpg';?>"/>
<img src="<?php echo $_SERVER["DOCUMENT_ROOT"].'\placeholder.jpg';?>"/>
<img src="<?php echo $_SERVER["DOCUMENT_ROOT"].'./placeholder.jpg';?>"/>
$_SERVER["DOCUMENT_ROOT"] is C:/wamp/www/ZendSkeletonApplication/public
Thanks to this: lost in code
As there was another answer that suggests enabling the remote option in module.config.php
and I can't yet add comments, I thought it would be best to answer that this file does not exist in newer versions of DomPDF.
If you need to include remotely stored images in a newer version you have to pass it as an option to the constructor:
$dompdf = new Dompdf(array('enable_remote' => true));
This fixed the issue I had.
