Question
I'm trying to find a way to add a body class "author" IF the current user is the author of the post they are viewing.
This is what I have so far...
add_filter( 'body_class','my_body_classes' );
function my_body_classes( $classes ) {
if ( !$current_user->ID == $post->post_author ) {
$classes[] = 'post-author';
}
return $classes;
}
Solution
The code isn't working because you haven't defined or retrieved the $current_user
or $post
variables from anyway. You've also got a !
here for some reason: !$current_user->ID
, which will just break the condition.
You need to use the appropriate functions to get their values, and also use is_single()
to make sure you're viewing a single post (otherwise the post author could be missing or something unexpected).
add_filter(
'body_class',
function( $classes ) {
if ( is_single() ) {
$post = get_queried_object();
$user = wp_get_current_user();
if ( $user->ID == $post->post_author ) {
$classes[] = 'post-author';
}
}
return $classes;
}
);
