Re: Data validation: check whether at least one of many fields has a value?

[Jeremy Burns | Class Outfit]

Here's an example:

The validation rule is:

'phone_home' => array(

'hasOnePhone' => array(

'rule' => 'hasOnePhone',

'message' => 'You must enter at least one phone number.',

'last' => true

)

),

The model function is:

function hasOnePhone() {

if (

$this->data['address']['phone_home'] != null || $this->data['address']['phone_work'] != null || $this->data['address']['phone_cell'] != null ): return true; endif;

}

Hi all

I'm seeing how to have many validation rules for one field everywhere,
but I couldn't figure out how to have on validation rule that depends
on many fields?!

I have a model with 3 fields. I want to check that at least one of
these fields has a value.

How can I achieve this?

Thanks, Josh
