I am using "How to Change the Review Author Display Name in WooCommerce" so that I can change the review author shown on the site to be the first name followed by surname initial.
add_filter('get_comment_author', 'my_comment_author', 10, 1);
function my_comment_author( $author = '' ) {
// Get the comment ID from WP_Query
$comment = get_comment( $comment_ID );
if (!empty($comment->comment_author) ) {
if($comment->user_id > 0){
$user=get_userdata($comment->user_id);
$author=$user->first_name.' '.substr($user->last_name,0,1).'.'; // this is the actual line you want to change
} else {
$author = __('Anonymous');
}
} else {
$author = $comment->comment_author;
}
return $author;
}
What I need to do is to use the first name only (not show the surname) and change all but the first and last characters to '*'.
So for example James becomes J***s and Michael becomes M*****l
Adjustments are:
comment added with explanation in the code
function my_comment_author( $author, $comment_id, $comment ) {
// NOT empty
if ( $comment ) {
// Get user id
$user_id = $comment->user_id;
// User id exists
if( $user_id > 0 ) {
// Get user data
$user = get_userdata( $user_id );
// User first name
$user_first_name = $user->first_name;
// Call function
$author = replace_with_stars( $user_first_name );
} else {
$author = __('Anonymous', 'woocommerce');
}
}
return $author;
}
add_filter('get_comment_author', 'my_comment_author', 10, 3 );
function replace_with_stars( $str ) {
// Returns the length of the given string.
$len = strlen( $str );
return substr( $str, 0, 1 ).str_repeat('*', $len - 2).substr( $str, $len - 1, 1 );
}
