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.

This generally a moot point since 99% of the rest of a site won't work without js anyway. 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).

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. chrs, john. -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/

I would assume most of the people know about perldoc/manpages/RFCs and white papers. people are looking for sample code, or corrections to their 'published code'. i was hoping to get some sample code to take cue from. after i thought about it a bit more, i liked the suggestion of Octavian Rasnita(and also fish), please read his/her response. he understood the question (and his response was balanced).

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.

How to get the multiselect select box or checkbox element values WITHOUT using CGI module
Hi, without using CGI.pm how can i collect the values of a multiselect element? say for e.g.: select name=hobbies id=hobbies multiple optionReading Books/option optionWriting Stories/option optionCollecting Coins/option optionCross Stitching/option optionTenis/option optionPlaying Cricket/option /select when the form is submitted, i have to get the selected values in an array. how can i do that? *if you are curious, (as per my understanding) even though CGI.pm would make it easy to get values out of parameters passed to the script by the web form. I would still have to do validation of values passed seperately. so why should i use a big module just to collect form data? i am using TT to display the form/HTML and javascript to validate input.

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.
