I am still new to drupal and was wondering if my approach to the following is ok.
I am developing a module. I have a form with a lot of fields. 1 of those fields is an input for an email address. Currently, on form submit, the input for the email adress is checked through a form validate function, like:
form_set_error('email', t('Email is invalid.'));
Is this the correct way to do something like this or does drupal have some special form attribute which automatically does this for me?
Btw, drupal is awesome. I used to develop in Joomla and Drupal is a pleasure to work with.
