6 node.php hook_form(&$node, $form_state)
7 node.api.php hook_form($node, &$form_state)

Display a node editing form.

This hook, implemented by node modules, is called to retrieve the form that is displayed to create or edit a node. This form is displayed at path node/add/[node type] or node/[node ID]/edit.

The submit and preview buttons, administrative and display controls, and sections added by other modules (such as path settings, menu settings, comment settings, and fields managed by the Field UI module) are displayed automatically by the node module. This hook just needs to return the node title and form editing fields specific to the node type.


$node: The node being added or edited.

$form_state: The form state array.

Return value

An array containing the title and any custom form elements to be displayed in the node editing form.
