What I've been doing is creating a subclass of Zend_Filter_Input that
adds the ability to automatically add filters and inputs from class
members and automatically sets up paths for filters/validators. So
the following is possible:
class Input_Form extends Jb_Filter_Input
{
$_filters = array ( ... );
$_validators = array ( ... )';
}
This simplifies code a lot, and is especially useful if you have a
lot of forms requiring validation.
If you're expecting one of your incoming variables to be an array
(say for instance the 'phone[]' variable you described) then
Zend_Filter_Input will automatically apply Filters and Validators to
each element of that array separately (i.e. it wont actually pass an
array to your filters and validators). So in your case you need to
name each of the fields separately and use the fields Meta-command to
specify which fields should be passed to your validator. That way,
your validator will recieve an array containing the fields you
specified. e.g.:
class Input_Form extends Jb_Filter_Input
{
$_filters = array ( ... );
$_validators = array (
'phone' => array (
'fields' => array ('phone-1', 'phone-2', 'phone-3',
'phone-4'),
'PhoneValidator'
)
);
}
Obviously you'd need to implement the phone validator first. SpotSec
had a great example article regarding validating multiple fields with
a single rule:

I'm curious how others are using the current (as of ZF 1.0.2)
implementation of Zend_Filter_Input. I'm trying to use it for a
contact form, but everything I've typed out seems clumsy and overly
complicated. (Maybe that's just the cost of flexibility, though,
because even the "less basic" examples in the documentation look
extremely convoluted.)
For instance, I have one hidden field (using CSS) on the form
that's used in spam detection. This field needs to remain
completely untouched by the filters I set, but in order to do that,
I have to explicitly assign the filters to /every/ other field (14
of them) rather than use the "*" wildcard.
Also, I have no clue how to handle multiple fields of the same
name. This same contact form allows the user to provide their phone
number if they wish. This consists of 4 fields that represent parts
of a U.S. telephone number, all with the name "phone[]": ([___])
[___]-[____] ext. [_____]
If any one can provide any insight or examples of their own of
their, that'd be great.
Thanks,
