get_bloginfo('site_url') returns 'home' option, which is confusing

[dd32]

According to the Template tags for get_bloginfo()

---

'url' - the Blog address (URI) is the URL for your blog's web site address and is set in Administration > Options > General. This data is retrieved from the home record in the wp_options table.
'home' - returns the same value as 'url'.
'site_url' - returns the same value as 'url'.

---

however the output when using latest SVN: (2.1-RC2 revision 4776)

get_bloginfo(""); "blog title"
get_bloginfo('url'); "blog url"
get_bloginfo('home'); "blog url"
get_bloginfo('site_url'); "blog title"

It may be that site_url has been depreciated(as it seems to be given that 'url' should just be used), however it may break some templates/plugins if its not included for backwards compatibility.

[dd32]

tracked down the get_bloginfo() function:

---

case 'url' :
case 'home' :
case 'siteurl' :

$output = get_option('home');
break;

Not having used Wordpress before now, i was unsure, I've just delved into the 2.1 source, and also the 2.0 source and noticed that it is indeed listed as 'siteurl' in both.. which means its probably just a wiki update instead..
Updating the wiki page..

Those should actually probably just be removed from the docs so people don't use them. I believe they're only there for backwards compatibility.

[markjaquith]

Agreed. We should deprecate some of these redundant (and immensely confusing) things.

But is this a code issue, or a documentation issue? We're going to have to keep those legacy options in the code, but we should not even *mention* the legacy options in the documentation. And we probably should add CLEAR comments that these are DEPRECATED and may be REMOVED at any time. Feel free to interchange the caps.

Of course, considering how well our warnings worked for the $table* business...

[rob1n]

Patch adds appropriate comments, and changes all instances of bloginfo('home') to bloginfo('url').

(In [4983]) Standardize on 'url' for fetching the blog's url. Props rob1n. fixes #3623
