[Phplib-users] OOHForms validation

[Peter T. <pte...@te...>]

Hi,

I noticed some strange behaviour in the text validation logic of OOHForms:

When using the Start method whith the $jvsname argument, some Javascript 
will be generated for validation purposes (triggered by method Validate()). 
This is handled in'"self_get_js" in the "of_text" extension of "of_element" 
in of_text.inc.
The validation uses the Javascript RegExp object and evaluates against the 
regular expression in $valid_regex.
So far so good.
However, after the Javascript correctly evaluates your input string, the 
function "self_validate" is called. Self_validate evaluates the string 
again, using PHP functions ereg or eregi and $valid_regex as expression again.
The problem now is that Javascript and ereg use different evaluation 
methods. Although there is an overlap, an expression valid for Javascript 
is not necessarily valid for ereg/eregi:  try for instance ^[\\\w+]*$ as 
regexp: OK in Javascript, but not in ereg and thus causing some nasty 
problems in the code.  Another nice one to try: ^[[:xdigit:]]*$  (this so 
called character class validates hexadecimal chars in ereg and has no 
meaning in Javascript).

Do I miss something, or is this an issue? If so, a fix would be nice.

As a workaround I'll stop using the Javascript option by not using $jvsname 
and rely on ereg/eregi in self_validate.

Cheers,
Peter
