Sat, 05/10/2008 - 6:14am — TUcThe form definition has set the optional $form['#base'] property to foo.
The book states that Drupal will look for theme functions called:
bluebeach_formexample_foo()
phptemplate_formexample_foo()
theme_formexample_foo()
These functions are incorrectly named, because drupal will look for "theme name" plus $form['#base']
The same issue with the validation and sumission functions:
formexample_foo_validate()
formexample_foo_submit()
bluebeach_foo()
phptemplate_foo()
theme_foo()
And for the validation en submission functions:
foo_validate()
foo_submit()
incorrectly named functions

Show the needed $form argument in the _validate() signature:
_validate($form_id, $form_values, $form) {
...
It would be helpful to show how the $form variable became available in the form_set_value() statement.

Mon, 06/25/2007 - 3:08pm — rcharneyUnlike the other hooks in this section, the form_alter hook takes just the module name as a prefix, not the form name. Thus, the function's signature is modulename_form_alter($form_id, &$form).

bar($form_id, &$form)
