In the first and second articles of this series, we configured Drupal core and content types. Now we're doing something more special in a effort to make our site more usable for our customers and save time when creating new content.

From now on, I can upgrade your site so it can be able to send SMS automatically.

Why? People is not always connected to the Internet, but they always carry their cell phones with them. That's why this service is so useful. You can't be sure they'll read an email from you, but most people reads all SMS they receive before deleting them. If you want to be extra-sure they are properly notified, you can send both an e-mail and an SMS, not a problem.

Please notice: This article is for Drupal 6.

It would be great if we could add and remove fields to the contact form the same way we add them to content types using CCK, don't you think? But at this moment, this is not yet possible. As of today, there's no module that let us do it using the control panel. We need to do it "geek way", writing code.

The good news is that, as usual, we don't need to hack Drupal's core. We just use hook_form_alter to make the trick.

OK, let's do it.

The concept is quite simple. SPAMbots browse the Internet like mad searching for forms to fill with their crap about enlarging things and meds for your little soldier friend not getting hard enough and all that. OK, this is the game, they want forms to fill, we'll give them some.
