In WordPress we can create custom shortcodes and we can show its output anywhere on the site. To create a shortcode, we will use WordPress built in function add_shortcode(), this function required two parameters, first “shortcode” and others “callback function”; callback function is the function that we will create in theme’s functions.php file.
function theme_name_movies_shortcode($atts = [])
{
$a = shortcode_atts( array(
'no_of_posts' => 5,
'title' => "Movies List"
), $atts );
$the_query = new WP_Query( array(
'post_type' => 'movies',
'posts_per_page' => $a['no_of_posts'],
));
if ( $the_query->have_posts() ) : ?>
<h2><?php echo $a['title']?></h2>
<ul>
<?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
<li><a href="<?php echo get_permalink($the_query->ID)?>"><?php the_title(); ?></a></li>
<?php
endwhile;
?>
</ul>
<?php wp_reset_postdata();
else :
__('No Movies');
endif;
}
add_shortcode(“movies_list”, “theme_name_movies_shortcode”);
For reference, check following function, suppose there is custom post type named “movies” and you want to show movie list in sidebar.
Now you can use “movies_list” shortcode in your website as following ways.
// Use shortcode in a PHP file.
echo do_shortcode( '[movies_list no_of_posts="5" title="Movies"]' );
Or you can add following statement in “text” widget.
[movies_list no_of_posts="5" title="Latest Films"]
