Add variable onto URL

chops

I am trying to add a variable onto a URL....but I would like some way to see if the current URL has variables ....and if so just tack it onto the end.

eg.
www.domain.com?var1=1&var2=2&var3=3
add var4
www.domain.com?var1=1&var2=2&var3=3&var4=4

or if no var's on the URL
www.domain.com
add var4
www.domain.com?var4=4

emcb_php

Hi,

Yes sure you can do that. It does depent what you want ti use it for.

In your example domain.com/?var4=4 taht would bean that the variable $var4 would be made avialable in your php app.

You can use it to display data from the query-string like this

--- file.php?name=Elfyn McBratney

<?php

$echo_var = $var4;

echo "Hello My Name Is" . $echo_var . ".";

and the outcome would be...

Hello My Name Is Elfyn McBratney

I think that should help,

Elfyn

vsego

$new_url .= (strstr($current_url, "?") ? "&" : "?")."var4=4";

chops

How would I get the $current_url.... $PHP_SELF is the file only....is there a variable or something that will give me the entire URL?

Also the above string work like this:
(strstr($current_url, "?") ? "&" : "?")."var4=4";

if there is a questionmark in the current URL [(strstr($current_url, "?")] then [? "&"] add the "&" sign and if not add the [: "?"] questionmark + var4 onto the end....

vsego

$current_url - call phpinfo() and decide what you need. Maybe $REQUEST_URI or something like that. There is a section in manual called "Predefined variables".

As for your comment of my code - I didn't get if it was just an explanation or you're asking me something.
