Drupal

• Open Source CMS
• 6 vs. 7

Catch-all Hooks
• hook_block()
• list, conﬁgure, save, view

• hook_taxonomy()
• delete, insert, update

• hook_comment()
• insert, update, view, validate, publish, unpublish, delete

• hook_nodeapi()
• alter, delete, delete revision, insert, load, prepare, print, rss item, search
result, presave, update, update index, validate, view


No Objects


DB Layer

• Uses straight SQL queries
• db_query() and db_query_range()
• db_fetch_object() or db_fetch_array()
• drupal_write_record()
