hook_form

Display a node editing form.

This hook, implemented by node modules, is called to retrieve the form that is displayed when one attempts to "create/edit" an item. This form is displayed at the URI http://www.example.com/?q=node/<add|edit>/nodetype.

Parameters

&$node: The node being added or edited.

Return value

An array containing the form elements to be displayed in the node edit form.

The submit and preview buttons, taxonomy controls, and administrative accoutrements are displayed automatically by node.module. This hook needs to return the node title, the body text area, and fields specific to the node type.

For a detailed usage example, see node_example.module.
