Add Get Variable To URL When One Or More Exist

[visualazza]

hi,

 

im having trouble adding a get variable to a url if one already exists.

 

eg

 

current url = http://www.example.com/index.php?var1=something

 

i want to be able to change this to

 

new url = http://www.example.com/index.php?var1=something&var2=another

 

even so i can have a few get variable there.

 

I can add the first var through a form or link, but how would i add more through a link or through the header function?

 

I am positivly stuck.

 

Thanks

If you where going to do it through headers then it would be like:

header("Location: http://www.example.com/index.php?var1=var1&var2=var2&var3=var3");

 

Same would be for a link:

<a href="http://www.example.com/index.php?var1=var1&var2=var2&var3=var3">Click here</a>

 

EDIT: Don't forget to use the $_GET variables on the link page.

$var1 = $_GET['var1']; //etc.

sorry, you misunderstand.

 

If my url already has a get var in it but i want to add another later how would i do this?

 

If one isnt there already then it just uses the standard ?var=string

I hate to ask, but what do you mean by add some later? You mean after you process the first link? Or are you talking about adding things while it is being redirected?

Okay; try this:

$url = (!empty($_SERVER['HTTPS'])) ? "http://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'] : "https://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];

 

That will get the current url, then you can use this:

$url = $url."&var2=another";
