hi i have a form ...i want to validate the fields in such a way it does not accept if the user is trying to enter numeric instead of characters..........
eg in a name field if the user is trying to enter number....the typed data should not come...it should act like readonly field..........

Jump to PostHi.
I use this function to validate name in my forms :
function valName($name) { $name = preg_replace(‘/[\s]+/is’, ‘ ‘, $name); $name = trim($name); return preg_match(‘/^[a-z\s]+$/i’, $name); }
Jump to PostI would validate on both client side and server side(because sometimes, the user might have disabled the javascript!)

I use javascript for any form validation that I require and resuse where required.
Javascript:
// Validates Numbers 0-9 0=48
function Numbers(e) {
var cc = (e.which) ? e.which : event.keyCode;
if (cc > 47 && cc < 58) {
return true;
}
return false;
}
Field:
onKeyPress="Numbers()"
Hope this helps, Regards X :)

I dont mean to say that your method doesnt work, but if you use this javascript function, the user can still copy and paste letters into the box. I havent tested MitkOK's code, but i think that would work better, since it would eliminate the chance of copy + paste.

Is it?
I havent tested copy n paste.
Well lets add it I guess, anyone know how to stop it in javascript?
Ill research when im feeling better (busted me hand) =(
