Custom Form validation in CakePHP

This is my form: I want to make sure that AT LEAST one of the name/email pairs are filled in, so I'm working on a custom validation rule in my model.

alt text http://files.getdropbox.com/u/240752/formfields.png

I originally thought it would a simple case of making the first name/email pair mandatory, but this doesn't cover the other fields if someone fills in the third one for example, and omits the email.

Also, I only need to check for a valid email address if the corresponding friend field is filled in.

Am I overthinking this? I think I need some kind of interaction between the rules, but I'm stuck hard.

How are your fields being generated? I assume you're using something like:

<?php echo $form->input('Friend.name'); ?> [html stuff] <?php echo $form->input('Friend.email'); ?>

Since doing that several times within a page will produce duplicate ids (like, "FriendName" would be the resulting ID for each field generated by <?php echo $form->input('Friend.name'); ?>), you're probably going to have to add a number to each field name as you're generating them and then loop over $this->data['Friend'] in your controller and invalidate the offending fields as you find them (if the name is present, but the email is not, as you say).

I don't think there's a built-in way for cake to handle a situation like this, but I've been wrong before!

I would write a custom validation method for this purpose: http://book.cakephp.org/view/150/Custom-Validation-Rules#Adding-your-own-Validation-Methods-152
