Zend Framework’s Zend_Validate

I’m used to validate the form in a typical Zend Framework application with Zend_Validate or course. It gives you the absolute power to use the build in classes for standard validation, as well as write your custom validation classes.

The problem I had was a bit odd! Zend_Validate_Alnum is supposed to filter all characters and numbers, but what about non Latin symbols!? The project I’m working on is multilingual and there are eight languages, including Arabic, Chinese and Russian! All these were incorrectly !not validated by Zend_Validate_Alnum, although there were only letters and numbers!

In fact whatever the string encoding was – it doesn’t seem to work! Perhaps I’m wrong, but so far this is the situation.

Recent Update

After few test I figured out the problem was not in Zend_Validate at all! My mistake the solution is:

iconv_set_encoding('input_encoding', 'UTF-8');
iconv_set_encoding('output_encoding', 'UTF-8');
iconv_set_encoding('internal_encoding', 'UTF-8');
