You should be able to simply take the ‘get’ function  and do an if( bp_get_last_activity( bp_displayed_user_id() ) to return a false/true result and wrap your markup in that

Use
https://gist.github.com/
to share your member-header.php file and put some notes in the area that you’re having trouble with.

Think we were hoping to see what you had tried or were having trouble with. In that snippet of code it actually shows the principle of checking whether a function returns  true or false in the  line <code>if ( bp_is_active( ‘activity’ ) ) :</code>

That line is saying if the activity component is active then render the code that follows it that ends just before the line ‘endif;’

In a similar way <code> bp_get_activity_latest_update(bp_displayed_user_id())</code> will only be true if there is a latest update.

To use the function as a check you need to wrap blocks of code in:

if():

endif;

Have a go if you still get stuck edit that gist code snippet so we can see your workings and advise.

N.B my earlier example function was incorrect  you need to use :

<code>bp_get_activity_latest_update(bp_displayed_user_id())</code>

and that is exactly what is being explained – read through again. The if block  – that is the start of the if to the endif – wraps any content you wish to hide; it says if this function has data do something – if the function has no data then the if( has_some_data()  ) is the equivalent of false and thus anything inside the block will not be shown:

thus:

if ( bp_get_activity_latest_update ( bp_displayed_user_id() ) ) :

show me stuff

endif;

will only show if there is activity data so wrap that around anything you don’t want to show if no data returned.

Do give it a go best way of working things out is to experiment – on a local site copy naturally.
