在您的主题的 「functions.php」 文件里粘贴以下代码:
function bbp_reply_content_append_user_signature( $content = '', $reply_id = 0, $args = array() ) {
// Default arguments
$defaults = array(
'separator' => '<hr />',
'before' => '<div class="bbp-signature">',
'after' => '</div>'
);
$r = wp_parse_args( $args, $defaults );
extract( $r );
// Verify topic id, get author id, and potential signature
$reply_id = bbp_get_reply_id ( $reply_id );
$user_id = bbp_get_reply_author_id( $reply_id );
$signature = xprofile_get_field_data( 'Signature', $user_id );
// If signature exists, adjust the content accordingly
if ( !empty( $signature ))
$content = $content . $separator . $before . $signature . $after;
return apply_filters( 'bbp_reply_content_append_signature', $content, $reply_id, $separator );
}
add_filter( 'bbp_get_reply_content', 'bbp_reply_content_append_user_signature', 1, 2 );
