The Bakery Everything CakePHP

Excellent job; very useful code.

I made a few small adjustments to allow it to validate non-strings.

I changed line 64

from:
if (isset($data[$table][$field_name]) &&

to:
if ( array_key_exists($field_name, $data[$table]) &&

so a null field value then may be (in)validated too. I also changed line 71

from:
if (isset($data[$table][$field_name]) &&

to:
if (!array_key_exists($field_name, $data[$table]) || !is_string( $data[$table][$field_name]) ||

I also threw the following check into the top of any validation functions expecting a string:
if (!is_string($val)) {
return false;
}

There might be something wrong with my code, but it works so far (in concert with isType/nonNull validation funcs I added). Also, you may want nulls to go unvalidated, but the controller should be able to handle that logic by popping null fields into the disabledValidate array.
