@Rohit: I need some more information to help you with this. What version of ZF are you using?

I’m guessing it’s the addPrefixPath in the different elements that causes the error. I have alimost the same code as above in a project that uses ZF-1.5.2 and it works fine.

If you follow the stack trace you can see what causes the error…

Ha! Never mind. The documentation on http://framework.zend.com/manual/en/zend.form.forms.html#zend.form.forms.config is incorrect. I have filed a bug. All the *refixPaths should be singular “prefixPath”

Pretty nice. I have this working fine when I use a custom Zend_Form. However, I cannot get it to work when building my form from a config/ini file. I keep getting the same error as post #5, that the validator plugin cannot be found. Any suggestions on what to add where so that the prefix path is found correctly?

@wenbert: I have it inside my library folder using the same class/filename scheme as Zend Framework:

library/FKK/Validate/EmailConfirmation.php

If you make sure the library directory is in the include path you should be fit to go!

Where do I put this file?
# class FKK_Validate_EmailConfirmation extends Zend_Validate_Abstract {

@Jason: Actually I do have a generic match validator myself but split it in two for the sake of the tutorial. I agree with you about it being a standard validator in ZF. There are plenty of forms who needs something like this.

Great Tutorial! For improvement,I’d like to make one custom validate class instead of two.

Here is just a quick modification:

1) class FKK_Validate_Match extends Zend_Validate_Abstract

2) line 6 change to
const NOT_MATCH = ‘NotMatch’;

3) Between line 54 and 55, add

$errorMessage = $fieldName . ‘ does not match’;
$this->setMessage($errorMessage, self::NOT_MATCH);

line 7 & 8 become useless.

Thus, you can apply this to both email and password to validate their match.

Further, I guess it should be a standard validator in Zend Framework.
