The bp_after_profile_content hook fires after the display of member profile content. You will need to:
- Write a custom function to “get” and “output” the signature.
- Hook your custom function to the hook I mentioned above so that the signature is displayed on the profile page.
No idea what that means, surprised this is not standard part of buddypress and even more surprised there is no plug to do this.
It is standard! At least if you use xprofile component to let your users enter their signature.
1) Create a new field. Call it Signature and give it a textarea type.
2) Once this field is edited by a user, during registration or later, the signature appears on his profile.
3) if you want this field somewhere else, for ex on the profile header, you simply write a function to call this field and hook it into the template you want.
Ie. Add this to child theme functions.php or bp-custom.php
function my_signature() {
if ( bp_is_active( 'xprofile' ) )
if ( $signature = xprofile_get_field_data( 'Signature', bp_get_member_user_id() ) ) : // field name; case sensitive
echo $signature;
endif;
}
add_filter( 'bp_before_member_header_meta', 'my_signature' );
Or to use Henry’s advice
add_filter( 'bp_after_profile_content', 'my_signature' );
