Hi All,

I have this page that I'm plonking into my PHPnuke site... It lists who recently visited the site, and how long ago it was... nice feature I think.

It works fine, however, the name of the person should link to their profile page - like this -
http://mydomain.com/user.php?op=userinfo&uname=sonicsnail

but its appearing as
http://mydomain.com/user.php?op=userinfo&uname=

so it takes you to a blank page.

Now I'm no expert with PHP, but I get the feeling that theres a syntax error in this bit of the code....

$content .= "<font class=tiny><a href=\"user.php?op=userinfo&uname=\"".$uname."\">".$uname."</a>:";

Also, I think that $uname should really be $username ??

here's the whole thing... hope someone can help me here...

The poster has demanded we remove all his contributions, less he takes legal action.
We have done so.
Now Tyberius Prime expects him to start complaining that we removed his 'free speech' since this message will replace all of his posts, past and future.
Don't follow his example - seek real life help first.

Alas..

Changing -

quote:
$content .= "<font class=tiny><a href=\"user.php?op=userinfo&uname=\"".$uname."\">".$uname."</a>:";



to

quote:
$content .= "<font class=tiny><a href=\"user.php?op=userinfo&uname=".$uname."\">".$uname."</a>:";



fixed it! A "\ was the problem!

*chuffed*

Messy is a good word to describe it...

I've been tweaking lots of bits of the PHPnuke system - even REALLY simple things like the way it formats a block of text - just adding a <Br> here and there etc - but the number of times its completely screwed the site due to a syntax error on my part is a pain in the ass.

Hopefully I'll get the hang of it...

Am I right in thinking that when "echoing" html, you have to put a \ before any "'s?

Any good online resources for PHP syntax?

You should escape (adding slash in front of characters is escaping) all "special" characters.

For more information about PHP syntax, take a look at PHP Manual...

Thanks Max.

::Edit::

Any idea why my browser is trying to force me to download the the manual pages (all PHP) rather than just browsing them? (on P3, winNT, IE5). The first link I clicked worked fine, but all others are downloads now.. and even that first page is doing the same too now!!?

I can browse manual pages without any problems. Maybe you should try to download all pages (you have link to zip file there) and try to open them locally...
