Suppose I have 3 posts on my wordpress site titled:

  • Test_post_1 with tag test_tag
  • Test_post_2 with no tag
  • Test_post_3 with tag test_tag

Suppose now that I have one page titled page_1. On that page I have some written text. At the end of that page I want to link to my 2 posts with tag test_tag. I want the 2 links to appear as post excerpts, with post title, featured image and about 50 words. (Here is an example of such post excerpts.)

I have did some reaseach on this, and it appears I need to use the php the_excerpt() function. This would result in making specific page templates in wordpress or adjusting page php code. I have some leads on how to do this already, but that is not what I want. I want a simple way to add post experts from the page editor in wordpress. Something as simple as a shortcode. Something like [excerpt tag="test_tag"] that I can put right after my text in the page editor. Has anyone any leads for similar simple ways?

You need a couple of things. A shortcode handler, and a custom query:

function wpse_186346_excerpt_length() {
    return 50;

function wpse_186346_excerpt( $atts ) { 
    $atts = wp_parse_args( $atts,
            'posts_per_page' => 2,
            // Any other default arguments

    // We don't need paging, always save a query
    $atts['no_found_rows'] = true;

    // Create query based off arguments from shortcode  
    $query = new WP_Query( $atts );

    // Start the buffer to "catch" our output below, so that we can return it as a string

    // Set our custom excerpt length
    add_filter( 'excerpt_length', 'wpse_186346_excerpt_length' );

    // Loop over the posts and output whatever markup you need
    while ( $query->have_posts() ) {
        the_title( '<h4 class="excerpt-title"><a href="' . get_permalink() . '">', '</a></h4>' );

    // Remove our custom excerpt length
    remove_filter( 'excerpt_length', 'wpse_186346_excerpt_length' );

    // Restore the current global post

    return ob_get_clean();  

add_shortcode( 'excerpt', 'wpse_186346_excerpt' );

And use it like so:

[excerpt tag="test_tag"]

Your shortcode arguments just need to match those available, so you're not limited to only tags!

  • Thank you. Given that your clear answer is about adding a php function (possibly through a child theme) I assume that there are no ready-made ways to do this in WordPress without adding/modifying code. May 7, 2015 at 6:15
  • There is nothing in core for doing exactly this. But we're using all the cool stuff core has to offer to do it! May 7, 2015 at 12:54
  • Yes, I have noticed that. I actually learned something about WordPress in the process. Thank you. May 7, 2015 at 13:23
