I used to be making an attempt so as to add a picture like a “new” picture to the posts that are simply revealed and are lower than 2 days previous.

I attempted utilizing a operate like this inside a WP_Query however it’s making use of to all posts.

add_action('the_title', 'insiderable_add_img_new');
operate insiderable_add_img_new($title) {
    $title = '<img src="https://insiderable.com/wp-content/uploads/2020/03/newicon.gif">'.$title;
    return $title;
}

That is what I attempted with WP_Query:

$events_query = new WP_Query(array('post_type'=>'submit', 'post_status'=>'publish', 'posts_per_page'=>-1)); 
if($events_query->have_posts()) : 
    whereas($events_query->have_posts()) : 
       $events_query->the_post();
       if (get_the_date( 'Y-m-d' ) === date( 'Y-m-d' )) {
        add_filter('the_title', 'insiderable_add_img_new');
    }
endwhile; else: endif;
wp_reset_postdata();
operate insiderable_add_img_new($title) {
    $title = '<img src="https://insiderable.com/wp-content/uploads/2020/03/newicon.gif">'.$title;
    return $title;
}
