Plugin comes with a widget, which can be added to sidebar
Q2. How to display featured posts in any desired section of theme(Developers)?
In order to display featured posts in your theme, use the following code to fetch the posts.
<pre><code>$featured_posts = Thfp_public::thfp_get_featured_posts();
</code></pre>
The above code return WP_Query object which you can use in a loop. Above static function accepts a parameter(int) which limits the number of posts which it can return.
Show the posts with the help of custom loop:-
<pre><code>if($featured_posts->have_posts()):
 while($featured_posts->have_posts()): $featured_posts->the_post();
 //Your code here
 endwhile;
endif;
</code></pre>
You can also use your own wp_query. Make sure you use ‘tag’ key to be ‘featured’.
<pre><code>$args = array(
 'post_status' => 'publish',
 'tag' => 'featured',
 //Use any other needed args
);
$featured_posts = new WP_Query($args);
</code></pre>
and then use the loop to display posts.
