validating....
 

hello guys,

im a newbie and i would like to know how can i validate a form to accept only 4 numerical characters....

thanx for any help given....:newbie:

It depends which language you use. Form itself (properties) can be set to accept max 4 characters in a field (depending on the filed type). The validation part (checking if it's numerical or not) must be done later, with Java Script, PHP or any other language.

would kinda help if you told us anythign at all about what languages your'e using...

thanx all for responding.....

im using php 4 and java script.

i just want that the input field show like a "warning" when an user tries to post the form having entered a number with less than 4 digits (123) in an input field....

i know that it can be validate with java....but i can't seem to find a good ol' example...:)

can u help me???

there's so much stuff on google... for example http://www.javascriptkit.com/javatutors/form7.shtml

thank you, i'll check it out...
