Jill and Mark at FleetThought are life savers! As a small, rural
library director where I *am* the IT staff, I was at a loss as to how to
customize my library's website template. Jill and Mark made my small
site feel like such a priority, and I got first class service! They
listened to my needs and made many changes I requested to make my site
beautiful and to make me a happy customer. I am so grateful for their
expertise and I cannot recommend them enough!
Although CCK automatically does some basic validation on your fields that you add to your Drupal content types, there are some cases where you'd like to do some additional validation for your site. One use case that I ran into recently was a basic text field that was being used to house hyperlinks for one of my websites. The text field had already been in place and working perfectly for months. Rather than do something drastic like replacing the field altogether with a field provided by the "Link" module, I decided to do a hook_form_alter to add in my own custom validation function.
