passing variables in a url

Anon

Hello,

A link in page 1:
<a href=\"selectforum.php?id=$row[name]\">$name</a></td>
passes the user to page 2:
where $id=messagedata (for example)

Another link takes the old $id and a new variable.
<a href=\"rowselect.php?subject=$subject&id=$id".SID."\">$subject</a>

How to get the $id over to a third page?
I don't want to set it as a session variable. I can see $id and its value up in the location field on page 3, but it's not accessible in my script.

Any ideas?
Thanks for any help.
Magnus

It looks like you should be able to access $id on your third page.

Make sure that you urlencode($subject) before you pass it in the query string, on your second page, otherwise spaces and other special characters might destroy the valid query string...

Thankyou,
<a href=\"rowselect.php?entry=$subject&table=$name\">$subject</a>
//this won't work

Here was the solution:
<a href=\"rowselect.php?table=$name&entry=$subject\">$subject</a>
//this will work

//$name comes from our first script. It's the db table name. As you
said, this should
actually be the table id, but for now it's the table name.

//$subject is for a row from our selected table ($name).

I didn't quite understand what you meant with url encode though. Can you explain?
