Re: [cgiapp] Data.FormValidator.js
Joshua,
Have you managed to figure out a work around for:-
'constraints' = {
'password1' = {
'constraint' = check_passwords,
'params' = [ qw( password1 password2 ) ],
},
},
...
sub check_passwords {
my ( $pw1, $pw2 ) = @_;
if ( $pw1 eq $pw2 ) {
return 1;
} else {
return 0;
}
}
I would have thought this is common enough to warrant a work around...
I couldn't see one in your examples.
Am I missing something?

Dealing with HTML requires a parser. Anything else won't make people happy. I see. But there isn't a Pure Perl parser available, and for those that really can't get HTML::Parser on their cheap shared hosting, isn't a regexp that works most/some of the time better than nothing? If it were me, the answer would be no. A minor template change could break your application in mysterious ways. I'd rather not have an HTML::FillInForm replacement than one that works sometimes and not others. -- Michael Peters Plus Three, LP # CGI::Application community mailing list #### ## To unsubscribe, or change your message delivery options, ## ## visit: http://www.erlbaum.net/mailman/listinfo/cgiapp## #### ## Web archive: http://www.erlbaum.net/pipermail/cgiapp/ ## ## Wiki: http://cgiapp.erlbaum.net/ ## ####

Just looking at the source code briefly, it seems that it's using regexes as part of it's lexing/tokenizing, which is completely appropriate. As much as the idea of writing a Pure Perl parser intrigues me, I don't have the time :( Especially as at this time I wouldn't actually be using it (my script is generating all the html input tags and parsing them into the html template). Have you thought about maybe using an XML module? XML::SAX has a pure perl driver. Maybe if your HTML is XHTML it could work. Or if you want, you can probably use a libxml based module. It's extremely common (installed on most systems) and has an forgiving/HTML mode. -- Michael Peters Plus Three, LP # CGI::Application community mailing list #### ## To unsubscribe, or change your message delivery options, ## ## visit: http://www.erlbaum.net/mailman/listinfo/cgiapp## #### ## Web archive: http://www.erlbaum.net/pipermail/cgiapp/ ## ## Wiki: http://cgiapp.erlbaum.net/ ## ####
Re: [cgiapp] Form validation best practices
On Sat, Jan 24, 2009 at 8:56 AM, Cosimo Streppone cos...@streppone.itwrote: Hi, any suggestions about the best practices, most used modules, cgi-app plugins for generic form validation? So far, I looked at: - Form::Processor - Data::FormValidator - FormValidator::Simple (and C::A::FV::S) I had used Data::FormValidator with CGI::Prototype and was thoroughly happy with it. Since I'm now doing a project with cgiapp, I ripped down C::A::P::DataFormValidator and and am pleased to death with it. It does so much heavy lifting... it validates the form and then if there are errors, it returns you to a certain page and you can get the errors _AND_ it fills in the form using HTML::FillInForm. One plugin, saved me tons of work! Thank you Mark Stosberg and the cgiapp community!!! -- Terrence Brannon (818) 359-0893 [cell] # CGI::Application community mailing list #### ## To unsubscribe, or change your message delivery options, ## ## visit: http://www.erlbaum.net/mailman/listinfo/cgiapp## #### ## Web archive: http://www.erlbaum.net/pipermail/cgiapp/ ## ## Wiki: http://cgiapp.erlbaum.net/ ## ####
Re: [cgiapp] Data.FormValidator.js
Apologies if this has gone too far offtopic...

Currently, there is no easy, built-in way to do this.
Many times, I'll just leave that up to the backend to handle. Of
course, it is possible to tie it in on the frontend. Take the
check_and_report function from the file Data/FormValidator.js, and
update the end part of it something like this:
if (! results.success()) {
...leave this stuff
} else {
// This is where you'd add the password eq check
// assuming the profile already checked password1 and password2
// had some valid value
var password1 = results.getField(frmObj, 'password1');
var password2 = results.getField(frmObj, 'password2');
if ( password1[0] != password2[0] ) {
results.changeStyle(frmObj, 'password1', badColor);
results.changeStyle(frmObj, 'password2', badColor);
alert(There is a problem with your form.\n\nThe entered
passwords do not match.);
return false
} else {
return true;
}
}
I would like to see Data.FormValidator.js get support for including
things like that in the profile. While it would break the profiles
compatibility with Data::FormValidator.pm, a filter could be
implemented to let the profile be used on both of them. I'm not
totally sure how that would work out though. At least for myself, I
usually generate the javascript profile from a profile written in
perl, and that would make it difficult to include a javascript
function definition inline.
I'm open to suggestions and patches, but that conversation should
probably be moved offlist or to the forum on the Data.FormValidator.js
berlios page.
Thanks,
