WKHTMLTOPDF didn't return any data

[abolkog]

I am getting this error when I set the engine to WkHtmlToPdf
Any ideas what did I do wrong ?

My configuration:
Configure::write('CakePdf', array(
'engine' => 'CakePdf.WkHtmlToPdf',
'margin' => array(
'bottom' => 15,
'left' => 50,
'right' => 30,
'top' => 45
),
'encoding'=>'UTF-8',
'download' => true
));

wkhtmltopdf version 0.9.9

Other engines are working fine but there are no images in the pdf file!

I am sorry , it appears the problem was with version 0.9.9
i removed it and installed 0.11.0 rc1 and it works great
Thank you so much for this plugin 👍

I am having the same issue, but I do have version 0.11.0 rc1 installed: "wkhtmltopdf-0.11.0-rc1 osx".

incorrect encoding also could cause this problem, cakepdf uses utf8 by default.
Besides that, i cant tell why wkhtml2pdf returns no content.

Anything I can debug to get to the bottom of this issue?

CakePdf can only render if any content is being returned, its hard to tell why wkhtmltopdf is not returning any data.
You could perhaps try with very simple view and layout template, not images and external css.
also you can try wkhtmltopdf command from console, to check if it works when calling it directly.

You could drop by on irc #cakephp on freenode and ping me

I did try using the console and it works fine. I also tried a simple HTML view, nothing fancy, just text, and still cannot get past that error message. :-/

I am not sure but if the console works fine maybe the problem is with your configuration
This is my configuration , its the default one actually nothing :

CakePlugin::load('CakePdf', array('bootstrap' => true, 'routes' => true));
Configure::write('CakePdf', array(
'engine' => 'CakePdf.WkHtmlToPdf',
'margin' => array(
'bottom' => 15,
'left' => 50,
'right' => 30,
'top' => 45
),
'encoding'=>'UTF-8',
'pageSize'=>'A4',
'download' => true
));

You can also try tracing the contents, in PLUGIN_HOMe/cakePdf/Pdf/Engine/WkThmlToPdfEngine.php, when I was googling about this i saw some post about the command ($command .= " --print-media-type";) might cause the problem, but I can't find now, sorry

Try re-installing wkhtml , maybe it will help.
This is how i installed it (working under ubuntu server)

wget https://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.11.0_rc1-static-i386.tar.bz2
tar -vxf wkhtmltopdf-0.11.0_rc1-static-i386.tar.bz2
mv wkhtmltopdf-i386 wkhtmltopdf
chmod a+x wkhtmltopdf
sudo mv wkhtmltopdf /usr/bin

Hi,

Alhamdulillah, I got wkhtmltopdf running on ubuntu after installing wkhtmltopdf as follows:

apt-get install wkhtmltopdf
apt-get install xvfb
echo 'xvfb-run --server-args="-screen 0, 1024x768x24" /usr/bin/wkhtmltopdf $*' > /usr/bin/wkhtmltopdf.sh
chmod a+x /usr/bin/wkhtmltopdf.sh
ln -s /usr/bin/wkhtmltopdf.sh /usr/local/bin/wkhtmltopdf
wkhtmltopdf http://www.google.com output.pdf

[reference: http://fedir.github.io/web/blog/2013/09/25/install-wkhtmltopdf-on-ubuntu/]

and configure the bootstrap with

CakePlugin::load('CakePdf', array('bootstrap' => true, 'routes' => true));
Configure::write('CakePdf', array(
'binary' => '/usr/local/bin/wkhtmltopdf', // set the correct path here
'engine' => 'CakePdf.WkHtmlToPdf',
'margin' => array(
'bottom' => 15,
'left' => 15,
'right' => 15,
'top' => 20
),
'encoding'=>'UTF-8',
'pageSize'=>'A4',
'download' => false
));

I cheat the CSS using standard html style.
