5. A PROBLEM
Need to add excerpt of a post to another
THE SOLUTION
Embed Post Plugin
http://wordpress.org/extend/plugins/embed-post

6. EMBED POST
function embed_post_shortcode( $atts ){
extract( shortcode_atts( array(
'post_id' => 0,
'type' => 'excerpt’ ), $atts ) );
global $post; [embed_post post_id=‘12’]
$post = get_post($post_id);
if($post->post_status == "publish"){
setup_postdata( $post );
$excerpt = '<div class="embed_post">';
$excerpt .= get_the_excerpt();
$excerpt .= '</div>';
wp_reset_query();
return $excerpt;
}
}
add_shortcode('embed_post', 'embed_post_shortcode');

7. MORE SHORTCODE
• Run Shortcode anywhere in template files:
do_shortcode([wpnepal]);
• Run shortcode in a text widget:
add_filter('widget_text', 'do_shortcode');
