Now to the SOPAC software itself:
Download from SVN:
$ cd /chemin/vers/drupal/sites/all/ $ mkdir modules $ cd modules/ $ svn co http://dobby.darienlibrary.org/svn/sopac/trunk/ sopac
In Drupal's administration settings, activate the module. Also, enable the dependencies:
The Drupal menu should now list these entries.
Then go into the settings of SOPAC.
Configure the paths to the Locum and Insurge libraries
Choose a URL prefix SOPAC, in my "catalog". Create a node with content like:
<?php print sopac_search_form('both'); print theme('pages_catalog');
Check the Input Format "PHP Code"
Check Move to front page
In URL path settings, set the SOPAC URL prefix you have chosen.
Go to the root of Drupal, a search form will appear.
Remember to empty Drupal's cache when something does not work.
Drupal offers a few blocks, which are not configured by default. You must specify on which page they should appear.
