hook_form_alter() and hook_nodeapi() to alter fields and insert additional data on insert

Solutions

As mentioned in the comments any extra fields you add to to a node form won't automatically be persisted to the database, the node module only takes care of the fields that it knows about.

Traditionally there are 2 options:

  1. Use CCK instead and add fields to the node that way. Then you don't need to take care of data storage/loading yourself.

  2. Add your own table for data storage using hook_schema(), making sure you have a column for nid (node id). Then in hook_nodeapi() use the insert and update ops to run a db_query() to insert/update the data in that table for the current node.

    Then you just need to load that data back from the DB on to the $node object in the load op of hook_nodeapi(). Your data will then be available at $node->field_name when you have a node object loaded with node_load().

hook_nodeapi() is great on nodes, but what can I use on non-node pages?

hook_nodeapi called multiple times with op='update'

Anyone know why this might be? If media_mover calls node_save during the process of saving the updated node, might that cause hook_nodeapi to be called multiple times...
