hook_prepare(&$node)

hook_prepare($node)

Act on a node object about to be shown on the add/edit form.

This hook is invoked only on the module that defines the node's content type (use hook_node_prepare() to act on all node preparations).

This hook is invoked from node_object_prepare() before the general hook_node_prepare() is invoked.

Parameters

$node The node that is about to be shown on the add/edit form.
