[Resolved] retrieve form field value on same page

[vinny199]

hi,

I think this must be quite standard and simple thing to do, but I don't know how.

If you have a submit form (that will insert into the database) with a field $email_address

the user types his email address in the text box, no problem.

But on the same page, I have a hidden field: $new_email

and I would like this new field to have for value exactly what the user has entered in the $email_address field

basically $new_email would pick up the value entered by the user for $email_address, and this on the same page (not by using a $POST action and retrieving the values on another page.

is that possible? how?

thanks for your help.

...standard and simple thing to do...

Yes, it is, with a client-side language such as javascript. PHP is server-side. See here.

Thanks for your reply.

But the url you sent me is a glossary of server-side / client side.

Is there any chance you could give a practicle example to my question?

some code to look at?

That would help.

thanks

Well, I guess I could, but since this is a PHP forum, I'll just give you another link.
