PHP help needed (Beginner)

[bozley05]

I'm in the middle of putting an affiliate program together (very basic), so I have got a password register/log-in user management script. So one of the PHP fields or whatever u call it is "username", which is used to say Welcome "username" at the top of the page, well i wanna use that same field to provide users with their affiliate code, eg. Your affiliate link is http://www.site.com/affil.php?id=username

Also with that, in the how do i pull the "id" from the url to make whatever the id is in to a hidden form field.

I hope you can understand what i'm getting at, thanks.

<input type=hidden name="id" value="<?php print $id; ?>">

hehe, i never thought it would be that easy, i'd tried doing:
<input type=hidden name="id" value="?php print $id; ?">

no wonder i got nowhere...

One question down, one to go..

I not sure if I got it properly but if their username is $username right, you do it like this:

Welcome <? print $username; ?>, your affilate code is <i>http://www.site.com/affil.php?id=<? print $username; ?>

Not quite sure If I got it properly.

Make sure you put it in right though


<input type=hidden name="id" value="?php print $id; ?">
Nope

<input type=hidden name="id" value="<?php print $id; ?>">
See, even when your inside a HTML tag, you still need to have the < and >

Butt... When you want tp echo (or print) something small and easy like that, yo ucan use the PHP "shortcut" like this:
<input type=hidden name="id" value="<?= $id ?>">
Just put a '=' in there and it acts like an echo (or print)

So you want to have the username in the link> Kaliber got it pretty much right, but the username is printed outside the link so it wont be part of the query string. Try something like this:


Welcome <? print $username; ?>, your affilate code is <i><a href="http://www.site.com/affil.php?id=<?= $username ?>" target="_blank">http://www.site.com/affil.php?id=<?= $username ?></a>
