Redmine for Drupal 6

This is a Drupal 6 module for the Redmine Issue Tracker. After installation and configuration, it displays all open issue in a block. This module was developed and tested with Redmine version 1.1.1. It also works great with Drupal 6 Block Refresh

The issues are grouped by projects, and the project tree is hidden on load. Javascript and css files (included) enable the projects to be hidden/unhidden, so you can keep an overview in case there are many projects and issues. The issues are directly linked to the issues in Redmine.

• Grab the module from my gitweb repository
• Adjust the file redmine_issues.module now or after upload, see below for details
• Install the module files in sites/all/modules/redmine_issues
• Enable the module
• go to Administer → User Management → Permissions and adjust access to Redmine Issues accordingly
• go to Administer → Site Bulding → Blocks, and enable the Redmine Issues Block
• Remmeber to enable the REST interface in Redmine: Administration → Settings → Authentication → “Enable REST web service”
• have fun

As there is no admin settings menu (yet), the following specific values have to be edited into the modules file:

• Adjust below line to reflect your Redmine url. SSL was not tested , and it will probably not work without reconfiguration of the CURL settings. But if your Drupal is running on the same machine as your Redmine: Don't worry about ssl

// use these settings for direct connections to Redmine
curl_setopt($tuCurl, CURLOPT_URL, "http://www.dl2keb.de/redmine/issues.xml");
curl_setopt($tuCurl, CURLOPT_PORT , 80);

• Adjust username and password. I recommend to create a read only user in Redmine:

// adjust username:password for direct connections to Redmine
//curl_setopt($tuCurl, CURLOPT_USERPWD, 'username:password');

• Adjust the path to your Redmine issues directory. Below line will be used for the direct links to the issues in Redmine:

$block['content'] .= '<ul><li><a href=http://www.dl2keb.de/redmine/issues/' . $value2['id'] . '>';
