While creating a new node, I'd like to pass a parameter in the URL:
node/add/page?plid=123 in order to put the newly created node in this menu item as its child.
I tried to
hook_form_alter() the node form but I couldn't populate the menu part, also I'd like to hide this part to the end user as they shouldn't alter it.
Should this be done in a
hook_node_insert() with something like this answer: How to enable menu link when creating a new node ?
