The default templates have body_class() in the body tag. The function body_class() is in post-template.php in the wp-includes folder:

function body_class( $class = '' ) {

// Separates classes with a single space, collates classes for body element

echo 'class="' . join( ' ', get_body_class( $class ) ) . '"';

}

Function get_body_class() is in the same file:

/**

* Retrieve the classes for the body element as an array.

*

* @since 2.8.0

*

* @param string|array $class One or more classes to add to the class list.

* @return array Array of classes.

*/

So I guess I could just add this to the code:

if ( bp_is_page( BP_MEMBERS_SLUG ) )

$classes[] = 'members';

Etc.

Should I copy this function to functions.php in the template, perhaps rename it, and add the lines for ‘members’ and ‘groups’ etc.?

Or should I aim for a shorter function that only adds something to what this code generates? Would that be possible?

Trying the blunt approach first…

Edit: I’ve tried with that BP_MEMBERS_SLUG line added directly to post-template.php, with $bp in global, but nothing shows up in the body tag.

What am I missing? Is Buddypress bypassing post-template.php anyway? The only class is “directory”.

Adding this to sandbox_body_class() produces the required result:

if ( bp_is_page( BP_MEMBERS_SLUG ) )

$c[] = 'members';

Thanks again r-a-y!

I did use Sandbox as an example, just to get something working quick. I had already taken most of the code out, but with your latest suggestions I can clean it up even further.

How is current_component identified? This is like herding cats.

Is there a way to make the tags mutually exclusive; if $c[] is ‘members’, it is NOT ‘groups’ or ‘blogs’ etc.?

I’m upgrading to 1.1.3, so I have to redo this mess again. I had it sorta working on 1.0, but it doesn’t work anymore.

r-a-y’s earlier solutions are over my head. I have no idea what conditionals are. I’m also trying to avoid having to add yet more lines to the header. I’d like to keep the template files script-free as much as possible. It should be possible to do with just a function called in the body tag.

Has anyone else figured this out?
