changing title of a node

In some cases you want to construct the title of a CCK node automatically, for example, you may want to construct it from other values on the form.
<?php
function mymodule_form_alter($form_id, &$form) {
// Check if we are on a node editing form for our type.
if (isset($form['#node']) && ($node = $form['#node']) && $form_id == $node->type .'_node_form') {
if ($node->type == 'type-to-change') {
// As we are going to construct the title ourself, there should
// not be any edit box for the title. As there is still a validator
// on the title field, we need to input a dummy value.
$form['title']['#type'] = 'value';
$form['title']['#value'] = 'this will not be used';
}
}
return $form;
}
function mymodule_nodeapi(&$node, $op, $teaser = NULL, $page = NULL) {
if ($op == 'validate' && $node->type == 'type-to-change') {
// We can change the value of the title in the validate hook
// for nodes. The form is actually passed as 3rd parameter
// to hook_nodeapi() for $op == 'validate'.
$form = $teaser; //messy
form_set_value($form['title'], 'some new value');
}
}
?>After some discussion with chx on #drupal, this seemed like the best solution.
