Join Jon Peck for an in-depth discussion in this video Using the Form API (FAPI) to create a form quickly, part of Drupal 7: Custom Module Development.
For web application developers, the act of building forms and processing form submissions …is a common occurrence. …Numerous coding frameworks contain standardized mechanisms that can be leveraged to create …forms, including support for common form elements, prevention of cross-site request forgeries, and so forth. …Drupal is no exception, containing a comprehensive system known as the form API or FAPI. …The Drupal form API provides a sophisticated network for building, validating, and executing forms.…
Using hooks, modules can cleanly manipulate any form within Drupal including those within …core, by extending and overriding functionality, instead of needing to rewrite or hack it in. …Drupal forms have four distinct steps; creation where the form elements and hierarchal structure …are defined using a standardized array, theming which refers to the manipulation of the design. …There are multiple levels of theming from individual form elements all the way up to …the structural layout of the entire page.…

Q: gmap3_tools is not working the way I expected it to. What version of gmap3_tools should I be using?
A: Use the free exercise file containing the version of gmap3_tools used for recording; the published version of the module on drupal.org has changed since recording and is not backwards compatible.
Q: I attempted to run the Drupal site root from the project files, but the site isn't loading. Why not?
A: The Drupal configuration file in sites/default/settings.php contains database configuration specific to the environment used to record the movie. This may be different than your environment. Edit the file and search for "windfarms" - you may need to change the database host, username, password, db name and port to match your specific environment.
