So I'm still having some failure on this, maybe related to my limited
understanding of regex in general or perhaps my limited understanding of the
zend validator regex class.
If I were to program my own little validator, the following would work fine:
if( preg_match("/[^a-z\' -]/i","valid8") )
return "fail!";
else
return "success!";
In my understanding, this would work because it would match the '8' in
'valid8'. If the string was 'validate' then nothing would match and it'd be
considered successful. However, when using the Zend regex validator in the
way I'm attempting to, I don't really have that flexibility. If I use the
above regex:
protected $_validators = array(
'lname' => array(array('Regex','/[^a-z\' -]/i'))
);
and try the string 'valid8', the validation will return true because it will
match the '8'. If I remove the '^' (/[a-z\' -]/i), it will ALSO return
true, because it will return true as soon as it matches the 'v'. I've done
quite a bit of digging around looking at both regular expressions and Zend's
implementation of regexs, but am at a loss. Is there a way to get around
this that I'm not seeing? Or will I have to write my own validator to
accomplish this? Thanks a lot for any input!
