It depends if the form is submitted using GET or POST and it is much harder
because you will need to do aditional work to decode the URL-encoded
elements, and you may make errors.
If you don't want to use CGI because is too big, you may want to use
CGI::Simple.
It doesn't matter if you validate the data using JS client side. It should
be also validated server-side also, but this has nothing to do with the way
you get the data from browser.

First of all, in addition to CGI.pm and CGI::Simple, there's also CGI-Minim=

Otherwise, the size in memory depends on somewhat different factors from th=

of the Ubuntu package size. Best way to determine it is to measure it.
Why are you worried about the memory size? Is this

You validate data with js? Are you fucking crazy? So, you think that if I=
want to hand you bad data I'm actually going to use your form to do it?
I'm not (read NOT) saying to remove this. What I'm saying is to use js to=
validate for people (like me) who don't read carefully before they click=
'go' or whatever. You DON'T trust any data at this point. You've got a f=
ew other points to validate that you might be able to trust: reverse prox=
y, db (ie, pg can validate columns), orm resultset / model, or the contro=
ller. Doing validation in some of these places might put load where you d=
on't want it however this can be considered validation. JS validation is =
just a ui thing. You should also write js to sanitize db data when being =
sent to a user. That way, if some xss got through on the up side, they do=
n't get it on the down side. Get it?
Ps, don't put validation (or any other logic in your template). Its a vie=
w - not for logic.=20
Pps, use placeholders or dbic (which does things right for you).

> by the way, question was: how do you collect the value of a multiselect, without using CGI module.
Octavian did answer that question; I'll do it again: you collect the
value of a multiselect by getting and parsing the value of the query
string in the HTTP request and/or by getting and parsing the value of
the HTTP request body, depending on whether the HTTP request is a GET
or a POST (and other refinements, like whether you want to support
query string paramaters given in a POST request).
The other thing that people are trying to communicate to you is that
*doing* that, and doing it properly, and doing it properly in all the
odd circumstances that usually don't happen but are allowed by the
HTTP spec, is a HARD problem. In addition to being a HARD problem --
and really, it's the worst kind of hard problem, that kind that's easy
to get *almost* right, so it won't fail until much later under the
absolute worst circumstances -- it's a solved problem. There are
multiple modules on CPAN that do this -- CGI and CGI::Simple have both
been mentioned, IIRC -- so, really, there's no need for you to do
this. One of those will work and it won't be any bigger than something
you write yourself.
Now, after that warning and explanation, if you still want to try --
and hey, some times resolving solved problems is good practice for
figuring out how to solve unsolved problems, right? -- then the first
thing to do would be to get and read the HTTP RFC. (Google will help
with that.) Then, get the source for one of those CPAN modules, and
read it. That will show you a fully working, debugged example of how
to do what you're trying to do, with tests -- so you can modify the
code, try to improve it, and see if it still works in the same way.
And after all that, if you come up with a way to do it better, you'll
be perfectly positioned to contribute it back to the maintainers of
the module, and you'll make *everybody's* life better.

john.

On the contrary, I think you are missing a few brain cells yourself
Shawn. Your friends at work may tolerate such obnoxious and juvenile
language, otherwise they wouldn't be your friends, but the members of
this list have a far higher price to pay to separate themselves from
your froth.
If you cannot find some politeness and mammers in you then I suggest you
withdraw and take your fury out on the cat, or the wife, or whomever
else it is that bears the brunt of your feelings when the rest of the

To the extent that his reply was possibly more focused than I gave him
credit for, I apologize.
The rest of my reply, however, stands: doing this yourself, unless
it's some sort of learning exercise, is a really bad idea. Further,
had Shawn not already addressed the issue, I would have included
something with the same basic message he delivered (albeit with less
swearing): relying on client-side Javascript code for input validation
is also a Really Bad Idea.

I don't think that anybody missed the point. The appropriate
response had already been given: either use an existing module or
explain why you can't (and why you don't go and read about CGI
standards yourself; CGI is not Perl specific).
When I read your post the very first thing that I thought to
respond about was also the JavaScript validation. Everything else
had already been covered and relying on JavaScript validation is
never ok, even if you do have a "trusted environment". Validation
isn't just to defend against attacks from malicious users. It's
also to ensure data integrity and the correct operation of the
application. Just because I'm using a browser that doesn't
support JavaScript doesn't mean that I'm a malicious user.
In short, people were trying to help, and it's not very polite to
tell people that they aren't helping to your satisfaction. Based
on my own personal experience, I imagine that you are trying to
find the "easy button". For whatever reason you don't want to use
existing modules, but you apparently also don't want to go to the
trouble of learning to do it yourself. I'm afraid there rarely is
an easy button. The best help that people can reasonably give you
is to tell you to either use an existing module or RTFM... And I
don't say that to be mean. I know what it's like to just want to
get started being productive and instead be faced with an
overwhelming prerequisist task... It's not fun, but it is
unfortunately the way things go.

Do you have any figures on how the trivial use of RAM/CPU by CGI.pm=20

CGI.pm is optimized though with it's own version of the lazy loader.
If you're already forking for CGI, then the trivial time it takes to
load CGI.pm compared to forking shouldn't concern you. If you're
looking for performance, you're already using mod_perl, and therefore
you're loading CGI.pm once for thousands of hits.
Either way, I haven't heard a valid reason from you yet. Just use CGI.pm.

Heh, the language actually had exactly the effect I was hoping. Your chances
of remembering this exchange are much higher now than if I would have just
said "please don't do this, its not very wise".
Here's the point - some of you all are accomplished developers and some have
a chance of getting there. You might be involved in a making an awesome
service one day. I might even use a service you design one day. I don't have
the time or energy to audit the public facing code for all the services I
use. I trust that you're smart enough not to do stupid crap (or I don't use
your service).
Since this possibility of me giving you more of my information than I give
most people is real, I felt to compelled to make my point as provocative as
possible (plus it was early and the thought of doing client side validation
really annoyed me).
Also, the completely valid point was made that the validation wouldn't
effect browsers that don't support js. This generally a moot point since 99%
of the rest of a site won't work without js anyway.
Either way, only use client side validation for client things. Don't trust
anything done by or on behalf of the client on the server.
Was that clean enough for you.
Ps, I don't remember reading anywhere that insanities were not allowed?
Iirc, the only mention of language was that this list is an English speaking
list.

That is only true of poorly coded Web sites. :) Which admittedly
is most Web sites, but I digress. I use Firefox's NoScript
extension, blocking EVERY domain by default. When I arrive at a
site that doesn't work like this then it had better have a good
reason for me to care or I'm leaving. It's also not uncommon for
me to browse the Web from a JavaScript-less text-based browser
(links-family, for example). Preventing me from finding the
information that I need is just silly. It's easier to make the
site work for me than it is to make the site fancy and Web 2.0
ish for people that also don't care and just want the damn
information. xD
JavaScript should be used to enhance the user experience, not
define it. Client-side validation is just part of that. It saves
the user a senseless request/response period and page
re-rendering. I personally believe that you should develop a
JavaScript-less site first. Then and only then should you develop
JavaScript to enhance the experience for supported users, if your
time and budget support this. You should have well defined goals
though. Just because you've added JavaScript doesn't mean you've
made the user experience better. Most sites today make the user
experience worse with JavaScript (which is why NoScript exists).

Not at all. You have made 'this exchange' about your use of abusive
language, and I would have to look back to see what point you were
making. Given your abusive manner I doubt if it was well-explained or
significant.
