7.x node.api.php hook_delete($node)

Respond to node deletion.

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_delete() to respond to node deletion of all node types.

This hook is invoked from node_delete_multiple() before hook_node_delete() is invoked and before field_attach_delete() is called.

Note that when this hook is invoked, the changes have not yet been written to the database, because a database transaction is still in progress. The transaction is not finalized until the delete operation is entirely completed and node_delete_multiple() goes out of scope. You should not rely on data in the database at this time as it is not updated yet. You should also note that any write/update database queries executed from this hook are also not committed immediately. Check node_delete_multiple() and db_transaction() for more info.

Parameters

$node: The node that is being deleted.

how to delete all content

sinasalek’s picture

Currently Drupal core does not offer any hook to do actions after a node/entity is inserted/updated/deleted in Database. So for example you can not send an email mentioning the node after the node is inserted because Drupal uses SQL transactions and the node is not yet fully written to database when hook node presave is called so if for any reason the transaction is rolled back, users will receive a false mail.

So Hook Post Action module introduces several new Drupal hooks to overcome this limitation:
- hook_entity_postsave
- hook_entity_postinsert
- hook_entity_postupdate
- hook_entity_postdelete
- hook_node_postsave
- hook_node_postinsert
- hook_node_postupdate
- hook_node_postdelete
