Passing vars from javascript

Anon

Hello

I have a problem.
I use javascript functions screen.width and screen.height
to get the client's screen resolution.
next i need these two params to go to my php script.

I've managed to pass the params as a string using teh following

$x='<script language="javascript> Document.Write(screen.width) <script>'

the problem is that this string cannot be compared or converted to anything.

Can anybody help me with this?
thanks.

Leon.

Javascript is client-side. If you want to pass information from the client to the server, you have to do that as a GET or a POST -- in other words, you have to load a new page with the information passed as arguments.

Well, this may be a little hokey, but wtf it's saturday and raining and I can't go outside....

Howzabout your first page all it does is send them to a blank page that gets the width/height vars you want and, when the page is loaded, immediately refresh them to another page like main.php?w=100&h=20. Then you could keep these stored (sessions, etc). Just a thought....

Thanks... 🙂

Are there no parameters that do the same in php?
they should be added anyway 🙂

Just be aware that users with JS turned off aren't going to get past page 1.

You really don't understand what it means when we say PHP is server-side, do you? Or that http is stateless? The server can't just reach out and grab info from the client. (And don't regale me of accounts of what you can do with vbscript--the tight integration of IIS and IE brings so many security issues I can't even count them all.)
