The big advantage to javascript is that it is fast, since a request isn't sent back to the server, processed, and then sent back. It also reduces network traffic, and reduces server load. > That's how I've always done it > because I know > PHP better than JavaScript, but wouldn't it make sense to > validate as much > of your form as possible using JavaScript before the form was > ever posted? > I'm just talking about the basics, like empty required fields, illegal > characters, string lengths, etc. even if you partially validate on the client, you still have to validate on the client side, which seems redundant to me. > > What are your preferred methods?

I only use javascript for things that I can't do with php, and I can validate with php. that's my 2 cents worth, Craig > > -- > Matt Grimm > Web Developer > The Health TV Channel, Inc. > (a non - profit organization) > 3820 Lake Otis Parkway > Anchorage, AK 99508 > 907.770.6200 ext. 686 > 907.336.6205 (fax) > E-mail: [EMAIL PROTECTED] > Web: www.healthtvchannel.org > > -- > PHP General Mailing List (http://www.php.net/) > To unsubscribe, visit: http://www.php.net/unsub.php > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
