Upgrading a classic theme for Gutenberg

With the release of WordPress 5.0 in early December 2018 web developers were forced to make a decision, install the Classic Editor plugin and continue to enjoy the post editor we’ve used for years or jump the new block editor experience. However, I quickly found a few of my themes were not ready.

Disable URL Guessing in WordPress

Placing the following PHP code snippet below in your theme’s funtions.php file will disable a WordPress feature that attempts to automatically redirect a bad url to an actual post or page with a similar url.

Please note, if there are any broken links to your website or it’s pages that benefit from this feature it will now lead to a standard 404 error page.

/* Disable URL guessing - https://www.bloggersignal.com/stop-wordpress-from-guessing-urls */
add_filter('redirect_canonical', 'pz_no_redirect_404');

function pz_no_redirect_404($redirect_url)
{
    if (is_404()) {
        return false;
    }
    return $redirect_url;
}

Removing specific Gutenberg core blocks and options

As I eagerly await WordPress 5.0 and its integration of the Gutenberg block editor there were several features that I found troubling from the standpoint of a web designer and developer. All of which are the result of too many options for the end user.

I work in an enterprise environment so many of these features would be fantastic for a blog, but can easily get in the way of a higher education website.

  1. Limit the available core blocks to only what’s needed.
  2. Remove the ability for users to set almost any font size in the paragraph tool.
  3. Remove ability for users to set their own text and background colors.

Limit the available core blocks

function pz_allowed_block_types( $allowed_block_types, $post ) {
    if ( $post->post_type !== 'post' ) {
        return $allowed_block_types;
    }
    return array( 
	'core/paragraph',
	'core/image',
	'core/gallery',
	'core/html',
	'core/list',
	'core/heading',
	'core/subhead',
	'core/quote',
	'core/audio',
	'core/cover-image',
	'core/file',
	'core/video',
	'core/table',
	'core/verse',

	'core-embed/spotify',
	'core-embed/flickr',
	'core-embed/vimeo',
	'core-embed/issuu',
	'core-embed/slideshare',
	);
}

add_filter( 'allowed_block_types', 'pz_allowed_block_types', 10, 2 );

Font sizes

// disable manual font sizes
add_theme_support( 'disable-custom-font-sizes' );

Remove the color palette

// disable custom colors
add_theme_support( 'disable-custom-colors' );

// remove color palette
add_theme_support( 'editor-color-palette' );

Dequeue Google Maps API for Events Calendar Pro

After Google started requiring information to obtain an API I realized I had no practical need for the API as all my events tend to be in the same location.

With the help from Modern Tribe support I created the following plugin. Once activated it will remove the API call to Google Maps. Likewise deactivating or deleting the plugin will restore Event Calendar Pro’s default behavior.
