WordPress MU

Hi,

Is there a string of code that will enable me to check which blog the user is on, and then use that data. Along the lines of this:

<?php if($_SERVER['HTTP_HOST'] == 'www.domain.com/news/' || $_SERVER['HTTP_HOST'] == 'domain.com/news/') {
include ('http://source.domain.com/php/navigation_news.php');
} else {
include ('http://source.domain.com/php/navigation_home.php');
}
?>

But obviously that doesn't work :P

What I'm trying to accomplish is:
If current blog is "news" include the file 'navigation_news.php', otherwise include the file 'navigation_home.php'.

I don't have any PHP knowledge so I'm guessing at the code!

If /news/ is a separate blog from /,

get_bloginfo('url')

should do the trick.

If /news/ is just a page within the main blog, though, you'll want to use $_SERVER['REQUEST_URI'] or something similar.

How would I write out the function using

$_SERVER['REQUEST_URI']

because some of the sections are blogs, and some aren't.
I tried

<?php if($_SERVER['REQUEST_URI'] == 'www.domain.com/news/' || $_SERVER['REQUEST_URI'] == 'domain.com/news/') {
include ('http://source.domain.com/php/navigation_news.php');
} else {
include ('http://source.domain.com/php/navigation_home.php');
}
?>

but that didn't work, it just includes navigation_home.php even though I'm on http://domain.com/news/

I also tried it using the

get_bloginfo('url')

method you suggested, is this the right way to impliment it?

<?php
$blog_url = get_bloginfo('url');
if($blog_url == 'http://domain.com/news/') {
include ('http://source.domain.com/php/navigation_news.php');
} else {
include ('http://source.domain.com/php/navigation_home.php');
}
?>

because that doesn't work either!

Try doing echo get_bloginfo('url'); to see what's output. It may be something simple - perhaps it's outputting the URL without the ending slash or something.

For troubleshooting, when in doubt, echo the variable you're working with - it'll solve a lot of problems.

Same thing with $_SERVER['REQUEST_URI'] - it's not going to output something like "www.domain.com/news/", it'll output everything after the domain name (including any query strings) - so "/news/", in your case. When in doubt, echo.

Thank you, the navigation is working perfectly now!
I change things around a bit, they no longer

include

seperate navigation pages, instead they change the class of a

<li>

to

<li class="active">

when they are on that blog.
Thanks for the advice :)
