Let’s have a look at the documentation: Functions File Explained. The functions file behaves like a WordPress Plugin, adding features and functionality to … Read more
It looks like it’s not easily accessible as it’s displayed as src: <title><?php echo get_bloginfo( ‘name’, ‘display’ ) . $separator . $title; ?></title> where the separator is: $separator = is_rtl() ? ‘ › ‘ : ‘ ‹ ‘; and the $title part comes from: login_header( $title=”Some title” , … ); But it looks like you’ve … Read more
Try the following: <?php $fname = get_the_author_meta(‘first_name’); $lname = get_the_author_meta(‘last_name’); $full_name=””; if( empty($fname)){ $full_name = $lname; } elseif( empty( $lname )){ $full_name = $fname; } else { //both first name and last name are present $full_name = “{$fname} {$lname}”; } echo $full_name; ?>
