Creating smaller buttons for Gutenberg

Often I find WordPress’ default button blocks are too large for some situations. Fortunately, extending Gutenberg blocks isn’t too difficult. Following the Gutenberg Handbook I’ve created short video and code samples to create addtional smaller button options without relying on a plugin.

Using is_multisite to loop in a post from another blog

Multisite is a powerful feature that allows us to manage multiple blogs within a single WordPress installation. In this post I briefly describe how to post content from the main site to a sub-site.

// Check if WordPress is using multisite
if ( is_multisite() ) {

global $switched;

// Switch to another blog by ID number 1 for the first site
switch_to_blog( 1 );

// Get a WP_Query that loops in a post from the main site

// Switch back to current blog


We can use any method you like to query a post from the main site. In this example I’m using WP_Query and Advanced Custom Fields to display a post using the notice category.

$current_post_ID = get_the_ID(); // the post's id is assigned to $current_post_ID

$args = array(
	'post_type'		=> 'post',
	'orderby'		=> 'date',
	'order'			=> 'DESC',
	'category_name'		=> 'notice',

// the query
$the_query = new WP_Query( $args );

<?php if ( $the_query->have_posts() ) : ?>

	<!-- pagination here -->
<div id="notice" class="row">
	<div class="small-12 columns">
	<!-- the loop -->
	<?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?> 
		<div class="notice">
			if ( function_exists( 'get_field' ) ) {  

				echo '<a href="' . get_field( 'redirect_to_url' ) . '">'; 
					echo '<h1 class="entry-title"><span class="dashicons dashicons-warning"></span>' . get_the_title() .'</h1>';
					echo '<div class="notice-content">';
						echo the_content();
					echo '</div>';
				echo '</a>';
			} else {
				echo '<a href="' . get_permalink() . '">'; 
					echo '<h1 class="entry-title"><span class="dashicons dashicons-warning"></span>' . get_the_title() .'</h1>';
					echo '<div class="notice-content">';
						echo the_content();
					echo '</div>';
				echo '</a>';


	<?php endwhile; ?>
	<!-- end of the loop -->
	<!-- pagination here -->
<?php endif; ?>

<?php wp_reset_postdata();

Allowing the site to post a custom message that links to another page for additional information. When the post isn’t available the blue box below will simply not appear on the page. I built this feature a long time ago but didn’t really have a practical use of until March when the pandemic required notification banners above everything on my 100+ site multisite.

Disable Lazy Loading Images Using the_post_thumbnail() in WordPress

The introduction of lazy-loading of images as of WordPress 5.5 improves site performance by delaying them until the user scrolls into view making our pages feel faster by only loading images as we need to see them.

The Problem

However, I needed a way to disable lazy loading for specific features like this image carousel where the last few slides would not load as they rotated into view. 🙁

Image not loading on reveal in a carousel
A blank space where an image should appear. Lazy Loading somehow prevented the image from displaying on first pass while using Foundation 6’s Orbit Carousel.

The Solution

Disable lazy loading of the carousel images using this template part.

the_post_thumbnail( 'carousel', [ 'class' => 'orbit-image' , 'loading' => false ] );

The code above is inspired by modifying the attr argument using an array.

Adding ‘loading’ => false to the array disables the feature for this homepage image carousel.

The Orbit carousel now loads all images at page load.

Before and After

loading=”lazy” appears within the image HTML tag.
loading=”lazy” no longer displays with the image.

Disabling lazy loading for a specific use of the_post_thumbnail() allows us to benefit from the feature everywhere else. 😀

If post hasn’t been modified recently in WordPress

Today an issue came up where a reader of one of a site I manage was referring to content that was out of date. Normally that’s not a problem but in this case it is a timely pandemic documentation page where the content is very likely to be out of date within a couple months if its not routinely updated.

To solve this challenge I decided to write a small function that will check the last modified date of a post and place an alert below the title and above the content. That notice would read…

This page has not been updated in 60 days. The information below may be outdated.

Which is a casual way of alerting the reader that if this information is timely perhaps check elsewhere on the site for a newer post. Likewise, if that person is looking for an older post they can safely disregard the notice. posting a discrete notice can come in handy depending on the context that brought a reader to the post.


// If post is older than 60 days return true
function jd_is_old_post($days = 60 ) {
	$days = (int) $days;
	$offset = $days*60*60*24;
	if ( get_post_modified_time() < date('U') - $offset )
		return true;
	return false;

Place within the WordPress Loop

// If post is older than 60 days display this notice
if ( jd_is_old_post() ) {
	echo '<div class="old-post-notice">';
        echo '<p><strong>This page has not been updated in 60 days. The information below may be outdated.</p></strong>';
    echo '</div>';

Attachment Image Snippet

This snippet for wp_get_attachment_image_src frequently appears in my theme development to select an image by its unique ID in the WordPress media library.

Handy for instances where logos, banners, or any other image frequently recurs on a website and you’d rather store that image in the media library where it can be replaced or modified dynamically.

// replace 7 with unique ID number of image
$image_attributes = wp_get_attachment_image_src( $attachment_id = 7, 'full' );

// retrieves alternative text from image information 
$alt = get_post_meta( $attachment_id , '_wp_attachment_image_alt', true );

if ( $image_attributes ) {
	echo '<img src="'. $image_attributes[0] .'" width="' . $image_attributes[1] . '" height="' . $image_attributes[2] . '" alt="' . $alt . '" />';

How it works

  • Set the unique id number in the snippet
  • Displays the image and relevant attributes

This code is based on the official Code References at for wp_get_attachment_image_src() and as get_post_meta().
