Yoast plugin is not showing meta description and meta keyword

Question

I set up Yoast on my WordPress website and I put title, focus keyword, and meta description for every single page of my website manually in Yoast widget. This shows up under the page but unfortunately the meta description and keywords is not appear on the page source. Is there any additional configuration required after installation of Yoast in header.php or somewhere in files?

Answer 1

function set_head_keywords() {
    $id = get_the_ID();
    if (!$id) return;
    $meta = get_post_meta( $id, '_yoast_wpseo_focuskw', true );
    echo '<meta name="keywords" content="'.$meta.'" />';
}
add_action( 'wp_head', 'set_head_keywords' );

copy paste this code in your function.php and it will work fine
