Recipe for adding Drupal node records - indexing

Question

I am looking for a recipe for adding Drupal node records.
I have identified three tables.
node_revisions
nid=249 - vid + 1?
vid=248 - auto-increment
node:
nid=250 - vid + 1?
vid=249 - auto-increment
content_type_my_content
vid=248 - from node_revisions table?
nid=249 - from node table?
Am I on right track?
Is there some helper functions for this?

Answer 1

If you are looking to programatically create nodes, use the Drupal API.
Start by creating a $node object. Fill in title, type, status, body, plus any CCK fields. At the end, call node_save($node);.
node_save will save your node object and do the necessary database work.
Check this out:
http://api.drupal.org/api/function/node_save/6
http://mediumexposure.com/how-build-node-drupal-programmatically/
The easiest way to see what each type of content type has as fields is to create a node (for example, Page), then use var_dump() to see the node's contents. That will show you every field you will need to use in your node object creation script.
Some folks will say you should create a form array, and call drupal_execute() on it so validation is performed before it's saved to the database. Either way is fine.

Kevin - With your help I have made good progress.
Node and CCK fields are now being populated.
Location (long/lat) is populated but not showing up on View screen.
Checkboxes are not being populated.
global $user;
$newnode = new stdClass();
$newnode->title = 'New node title';
$newnode->body = "this is a new node, created by import function";
$newnode->uid = $user->uid;
$newnode->type = 'items';
$newnode->status = 1;
$newnode->promote = 0;
// CCK fields
$newnode->field_myfield1[0]['value'] = 'test 1';
$newnode->field_myfield2[0]['value'] = 'test 2';
$newnode->field_mycheckbox[0]['value'] = 1;
// longitude, lalitude
// $newnode->locations[0]['lid'] = ?;
$newnode->locations[0]['street'] = 'xx';
$newnode->locations[0]['city'] = 'xx';
$newnode->locations[0]['province'] = 'xx';
$newnode->locations[0]['postal_code'] = 'xx';
$newnode->locations[0]['latitude'] = 0;
$newnode->locations[0]['longitude'] = 0;
$newnode = node_submit($newnode);
node_save($newnode);
content_insert($newnode);

OK. here is the full recipe. Drupal does the rest automagically.
global $user;
// Node fields
$newnode = new stdClass();
$newnode->title = $data[0];
$newnode->body = $data[1];
$newnode->uid = $user->uid;
$newnode->type = 'mytype';
$newnode->status = 1;
$newnode->promote = 0;
// CCK fields
$newnode->field_myfield1[0]['value'] = $something;
$newnode->field_myfield2[0]['value'] = $something;
$newnode->field_my_checkbox[0]['value'] = $something;
// longitude, latitude
$newnode->field_loc_latitude[0]['street'] = $something;
$newnode->field_loc_latitude[0]['city'] = $something;
$newnode->field_loc_latitude[0]['province'] = $something;
$newnode->field_loc_latitude[0]['postal_code'] = $something;
$newnode->field_loc_latitude[0]['latitude'] = '';
$newnode->field_loc_latitude[0]['longitude'] = '';
$newnode = node_submit($newnode);
node_save($newnode);
content_insert($newnode);
