Image error in DOMPDF for ZF2

Question

Hello everyone and welcome, sorry about my english not my main language. I'm a beginner on Zend Framework 2 also. I got an issue with DOMPDF in ZF2, when i try to show an image in my web page (virtualhost with apache2, the folder in desktop). For example:

<img src="/home/luifer/logo_uca.png" alt="logo_uca" />

With the error:

[Sun May 18 12:28:45.023452 2014] [:error] [pid 7195] [client 127.0.0.1:57089] PHP Fatal error: Uncaught exception 'DOMPDF_Exception' with message 'No block-level parent found. Not good.' in /home/luifer/Desktop/zf2-tutorial/vendor/dompdf/dompdf/include/inline_positioner.cls.php:37\nStack trace:\n#0 /home/luifer/Desktop/zf2-tutorial/vendor/dompdf/dompdf/include/frame_decorator.cls.php(700): Inline_Positioner->position()\n#1 /home/luifer/Desktop/zf2-tutorial/vendor/dompdf/dompdf/include/inline_frame_reflower.cls.php(36): Frame_Decorator->position()\n#2 /home/luifer/Desktop/zf2-tutorial/vendor/dompdf/dompdf/include/frame_decorator.cls.php(711): Inline_Frame_Reflower->reflow(NULL)\n#3 /home/luifer/Desktop/zf2-tutorial/vendor/dompdf/dompdf/include/page_frame_reflower.cls.php(123): Frame_Decorator->reflow()\n#4 /home/luifer/Desktop/zf2-tutorial/vendor/dompdf/dompdf/include/frame_decorator.cls.php(711): Page_Frame_Reflower->reflow(NULL)\n#5 /home/luifer/Desktop/zf2-tutorial/vendor/dompdf/dompdf/include/dompdf.cls.php(949): Frame_Decorator->reflow()\n#6 /home/luifer/Desktop/zf2-tutorial/vendor/dino/dompdf-module/src/ in /home/luifer/Desktop/zf2-tutorial/vendor/dompdf/dompdf/include/inline_positioner.cls.php on line 37

When i open the same page on the browser manually (right click open page with browser) the image shows in the page.

Just in case, my controller function:

    public function extraordinarioAction()
{
    //quitar de la bd

    $pdf = new PdfModel();

    return $pdf;

}

And my view page is extraordinario.phtml with a html page on it. I tried a simple page with a loading image and nothing shows, just a blank page with this error.

Anyone knows how to solve this problem? I already did some things like enabling the mbstring.

Any ideas? And thanks in advance.

Can you clarify your setup? The No block-level parent found message usually indicates that no HTML was passed to dompdf. Could be an issue with an earlier version of dompdf or it could be that you're passing uninitialized/null data to dompdf. — BrianS

Per the other answer: the issue might be raised because DomPDF cannot read the file. Since you have DomPDF running in your web application, php probably is owning the process (e.g. www-data). This user should have read access to the image you want to read.

Another issue is that you have the image inside /home/luifer. Sometimes user directories are unreadable for other users.

So: your best option is to place the image in a shared location (e.g. somewhere in /var/www). Otherwise, make sure the file is readable for others (chmod a+r logo_uca.png) and all parent directories are executable for others (chmod a+x /home/luifer). Please check every directory, you say "the folder in desktop" so if your file is placed in /home/luifer/Desktop, check the Desktop file as well.
