Drupal 6: Silverpop AddRecipient Module

Parent Feed: 
Badzilla

This module (which requires the Silverpop XML API module to be installed) provides the facility to add recipients to a Silverpop database. By default this is through a 'Subscribe now' block or node, both of which can be themed. In addition, there is functionality to delete a recipient from a Silverpop database. User permissions (for the nodes) and block permissions (for the blocks) can control the visibility of the forms.

Installation

Installation is by the usual Drupal mechanism. Once the module is installed, permissions should be set by going to admin/user/permissions. It is important to ensure that these are set correctly to prevent unauthorised access through to the Silverpop API.

Usage

To create a form to capture an email address, go to node/add/silverpop-subscribe-now. You will need to provide a title and a database id. This will provide both a unique block and a node. To make the block visible you will need to go to admin/build/block/list and configure as appropriate. The blocks can be identified by their nid or by the titles they were created with.

Those uses with the correct permissions will see a link to silverpop/remove_recipient in the navigation menu (providing this itself is visible on your system). Use the form from this link to delete email addresses from a database.

Limitations

This system captures email addresses which can be useful for newsletters and campaigns. It does not capture other information such as names / titles etc. It would be possible to re-factor the code to do this as an exercise at a later date.

The RemoveRecipient API call assumes there is only one key, of Email, in the database and will not work should this not be the case.
