control user input in textbox

[keikei]

Is there anyway for me to disable certain keys while the user is typing in an input box?

example if the input box is for integers only, I would like to be able to control what users can type in the textbox, by disabling alphabetic characters, in order to lessen data entry errors.

I saw this kind of thing done in Visual Basic 🆒 , I think It has something to do with keypress and manipulating ascii codes. IS there any way for me to do this in PHP?? 😃

Yes but it requires client side scripting which is off topic for these boards. Try http://www.javascript.com

Not in PHP. PHP is server side. The PHP is parsed before it is ever sent to the browser. You need a client-side script like JavaScript to do this, and it can be done in JavaScript.
