Buddypress Tags: bp_get_nav()

This tag uses the $bp->bp_nav global to fetch the navigation within a BuddyPress installation.

Each component adds to this navigation array within its own [component_name]_setup_nav() function.

This navigation array is the top level navigation, so it contains items such as:
[Blog, Profile, Messages, Groups, Friends].

The function will also analyze the current component the user is in, to determine whether
or not to highlight a particular navigation item.

BuddyPress 1.1 is now available for beta testing. This version is intended for testing only, you should not try running it on production sites. You can download the beta via this zip file, or via subversion.

If you download the zip version you will need to download bbPress 1.0 separately. Please extract bbPress into the folder “bp-forums/bbpress” inside of the BuddyPress plugin directory.

As always, please report bugs on our trac site with the milestone “1.1″. You can also view all outstanding bugs for this version. Patches for any of those bugs are very welcome. Please use your BuddyPress.org username and password to log into the trac site.

Update: Please make sure you read the installation instructions as there are changes from previous versions.

How to Install Buddypress in your wordpress MU?

Buddypress is a great tool for creating a social network site into your wordpress MU installation. As we know, wordpress MU is already a great of this kind. But buddypress adds some more spice and some more useful tools for you and your users.

I have just installed this feature in my MU blog(I wont tell you the address of that ), and I am learning the same. I will keep you posted in various features of this. But for starting, lets have look at the installation steps:

Installing BuddyPress from the combo download is a simple process.

1. Make sure you have WordPress MU set up and working correctly.
2. Download the combo archive of buddy press and extract it to your server.
3. Move contents of the extracted folder into “wp-content/mu-plugins”. All files should be in the root of “mu-plugins” not in a sub folder. For example, “mu-plugins/bp-core.php” NOT “mu-plugins/buddypress/bp-core.php”.
4. Move the themes to the correct locations. In the folder “mu-plugins/buddypress-theme” you will find two folders “buddypress-home” and “member-themes”. Move the “buddypress-home” folder to “wp-content/themes/” and move the “member-themes” folder to “wp-content”.

You should now have the following folder locations “wp-content/themes/buddypress-home” and “wp-content/member-themes/buddypress-member”.

5. Check the permissions on all the files you have just uploaded. They should be 755.
6. Enable the home theme for use by logging in as the WordPress MU site administrator and heading to “Site Admin > Themes” in the wp-admin area. Activate the theme “BuddyPress Home” theme via the Design or Appearance Menu.
7. Go to: “Site Admin > Profiles” in the wp-admin area.

Here you can set up profile groups and fields for users to fill in. Any fields you add
to the “Basic” group will appear on the signup form along with an avatar upload option.

8. If this is a brand new WPMU install you will need to enable registrations. Head to: “Site Admin > Options”. Check the “Enabled” radio button under “Allow new registrations” and hit the update options button. You can enable/disable blog registrations if you wish.
9. You are all set. You can customize some BuddyPress options in the “Site Admin > BuddyPress” menu item in the wp-admin area.
