PDF export support with wkhtmltopdf - recommended

myDBR supports wkhtmltopdf when installed on the server. wkhtmltopdf uses the Webkit rendering engine to convert content to PDF. Using wkhtmltopdf enables pixel-perfect PDF reports generated on the server.

To install wkhtmltopdf, follow the instructions on the wkhtmltopdf website. wkhtmltopdf will be installed as a command-line tool and should be found in the PHP path. If it cannot be added to a PATH variable, a direct link to the command can be given in mydbr/user/defaults.php by setting the $mydbr_defaults['export']['wkhtmltopdf']['command'] variable to a full path to the command.

Example if wkhtmltopdf is not found in PHP's PATH:

$mydbr_defaults['export']['wkhtmltopdf']['command'] = '"C:\Program Files (x86)\wkhtmltopdf\wkhtmltopdf.exe"';

Once you have installed wkhtmltopdf to the server, go to 'Environment settings' and see the 'Installed modules' if PHP is able to see the program. If not, you may need to define the full path to the command in $mydbr_defaults.

myDBR will check for existence of wkhtmltopdf once when user logs in. If you want to disable the check you can tell myDBR that wkhtmltopdf is installed, by setting the following into user/defaults.php:

$mydbr_defaults['export']['wkhtmltopdf']['skip_version_check'] = array(
'wkhtmltopdf_exists' => true,
'wkhtmltopdf_version' => '0.12.5'

You can also skip the version check if wkhtmltopdf is not installed. Use definition:

$mydbr_defaults['export']['wkhtmltopdf']['skip_version_check'] = array(
'wkhtmltopdf_exists' => false,
'wkhtmltopdf_version' => ''

If you have trouble getting the PDF export to work after installing the wkhtmltopdf, try following steps:

  • Check that myDBR sees the wkhtmltopdf installed. Access https://[yourserver.com]/mydbr/tools/troubleshoot/wkhtmltopdf.php. If not, check the PATH/$mydbr_defaults['export']['wkhtmltopdf']['command'].
  • Add a debug command to the beginning of the report, run the export as PDF and follow the instructions. The command to be added:
    select 'dbr.export.options', 'debug', 1;

Graphviz support

Graphviz adds support for the hierarchical and network charts. In order to take advantage of Graphviz charts, the Graphviz software needs to be installed into the server.

  1. Graphviz Download and install the latest Graphviz support from https://www.graphviz.org/download/ for your environment.
  2. Command path If myDBR tells you that the Graphviz commands (dot/neato) cannot be found, you can define the path to them in user/defaults.php
    $mydbr_defaults['graphviz']['command_path'] = '/opt/local/bin/';
    for your environment.
