Respond to creation of a new node.
This is a node-type-specific hook, which is invoked only for the node type being affected. See Node API hooks for more information.
Use hook_node_insert() to respond to node insertion of all node types.
This hook is invoked from node_save() after the node is inserted into the node table in the database, before field_attach_insert() is called, and before hook_node_insert() is invoked.
$node: The node that is being created.
Note: this list is generated by pattern matching, so it may include some functions that are not actually implementations of this hook.
function hook_insert($node) {
db_insert('mytable')
->fields(array(
'nid' => $node->nid,
'extra' => $node->extra,
))
->execute();
}
