Page title not showing up

Question

I have this in my header.php file ->

<title><?php is_front_page() ? bloginfo('description') : wp_title(''); ?> - <?php bloginfo('name'); ?></title>

This shows title in my browser window for all pages except one. I looked from my admin panel under the Pages section, if there are something missing, but did not find anything(or did not know where to look). Where should I look to solve this problem and what should I edit?

Answer 1

to show the page title for the page set as the 'blog' or 'posts page', you need to add some code, maybe via a filter on wp_title();

example:

add_filter( 'wp_title', 'wpse_174379_show_posts_page_wp_title' );
function wpse_174379_show_posts_page_wp_title( $title ) {
    if( get_option( 'page_for_posts' ) ) { 
        $posts_page = get_post( get_option( 'page_for_posts') ); 
        $title = ' ' . $posts_page->post_title . ' ';
    }
    return $title;
}
