  • 0

I have been trying to convert an html page to PDF with out any luck, I have tried to use wkhtmltopdf (http://code.google.com/p/wkhtmltopdf/) and the PHP class provided by the same developers (http://code.google.com/p/wkhtmltopdf/wiki/IntegrationWithPhp) although the following command executed correctly in terminal:

wkhtmltopdf http:/www.googl.com test.pdf

I was unable to execute the command in PHP because of the following error:
cannot connect to X server.

Can any one provide me with a step-by-step tutorial in order to be able to convert html/css to PDF file, whether using wkhtmltopdf or any other decent solution.

Thanks in advance

here is the class that i have used http://code.google.com/p/wkhtmltopdf/wiki/IntegrationWithPhp

and below is my code

$html = file_get_contents("test.html");

$pdf = new WKPDF();

$pdf->set_html($html);

$pdf->render();

$pdf->output(WKPDF::$PDF_EMBEDDED,'sample.pdf');

Below is the error:

Fatal error: Uncaught exception 'Exception' with message 'WKPDF didn't return any data.
/usr/bin/wkhtmltopdf: /opt/lampp/lib/libxml2.so.2: no version information available

    I found the solution, The following error “No protocol specified wkhtmltopdf: cannot
    connect to X server :0” was basically caused by on old version of “wkhtmltopdf” which was installed using apt-get. The solution was to download the static binary from the code.google using the following link:
    http://code.google.com/p/wkhtmltopdf/downloads/list

    and then perform the following actions: 

    tar -jxvf wkhtmltopdf-0.11.0-static.tar.bz2
sudo aptitude install ia32-libs

    Next, you’ll have to make a symbolic link pointing to WKHTMLTOPDF in /usr/bin.

    sudo ln -s /full_path/WKHTMLTOPDF /usr/bin/WKHTMLTOPDF
