Yes and no; you may want to compare against a raw value. As it is, it would be _incredibly_ difficult to make this happen, as the validators must work both inside _and_ outside a Zend_Form context (i.e., they could also be used with Zend_Filter_Input, in a custom validator chain, or standalone). Additionally, there may be values not handled by your form that could still be part of the context. While it could be done, I'm not sure if there's a clean way to do it that would be flexible enough to also address some of the above items. > Perhaps this can be mentioned in the docs and/or changed in future > versions. It really took me for a spin. Thoughts anyone? -- Matthew Weier O'Phinney Software Architect | [email protected] Zend Framework | http://framework.zend.com/
