function faq_ask_form_faq_node_form_alter in FAQ_Ask 7

Parameters

array $form: The edit form to modify.

array $form_state: Form state information

Return value

array $form Modified form as called by reference

File

./faq_ask.module, line 234

This module is an add-on to the FAQ module that allows users with the 'ask question' permission to create a question which will be queued for an 'expert' to answer.
