Upload Custom Block Types in WordPress

When you take a look at the Gutenberg “Button” block and click on the Sort tab (cookie moon section) you will notice that you will be able to choose between Fill or Outline for its styling. What did you want while you wanted to load additional alternatives? In another way did you want to load style alternatives for other blocks?

In this data I can show you suggestions on how to record your custom block sorts.

What are block sorts?

If you’ve landed on this, you probably already know what Block sorts are. But again, just in case I could explain it briefly. It’s actually easier if I let wordpress explain it to me. Here’s an excerpt from the legitimate Gutenberg documentation:

Block Sorts allow you to perform selection sorts to present blocks. These are done by adding a className to the block wrapper. This className can be used to provide an alternate style for the block if the block style is selected

wordpress.org

So, block sorts are alternatives that you can simply click on when you enhance a block. When you do that, it will inject a class name into the block. This class name can then be referenced via CSS.

Why join Custom Designed Block Sorts?

Registering custom sortings means that you will produce other designs on your blocks that you can use in many contexts. For example, if your site is white and you also insert a white symbol in a submission, it will not look good. It is very important to register a “Bordered” style for the Image block that provides a gray border around the image that can make it stand out.

Sure, it’s fine to use the easy environment in Block > Complicated > Additional CSS Elegances with the intention of loading custom class names on your blocks. On the other hand, this requires you to remember the elegance names. And if you’re working on a client’s website, they’ll appreciate an easy option to apply custom designs to their blocks.

An added bonus is that when you save custom block sortings you will be able to set the inline CSS for the way, that way the CSS is automatically added inside the editor and frontend whenever the way is selected.

Join a new block style

For the purposes of this data, I would like to focus specifically on server-side recording of custom sorts. In short, using PHP instead of Javascript. For many consumers, this may also be easier and faster. In short, you will download the code directly into a code snippet plugin with the intention of uploading custom block sorts to the website.

So, to register a new block style with PHP, you will use the register_block_style function, as it should be called. This function takes two arguments: $block AND $style_propertiesSo you can tell it what block you need to load your types and then a matrix of how it hosts.

This is an example of a brand new “Simple” style for the Checklist block:

/**
 * Join custom block sorts.
 *
 * @link https://www.wpexplorer.com/how-to-add-custom-block-styles-wordpress/
 */
function wpexplorer_register_block_styles() {
	register_block_style(
		'core/checklist',
		[
			'name'  => 'list-plain',
			'label' => 'Plain',
		]
	);
}
add_action( 'init', 'wpexplorer_register_block_styles' );

With this code added to your website as you insert a new control block, you will need to see a new selection to select a “Simple” style like this:

Notice how in my example I am using ‘core/checklist’ because the block defines what I want to add my custom styling solution to and not just ‘checklist’. All of wordpress‘s default block names are prefixed in this approach. If you are unsure what the right type of define is for a block, take a look at the list of all wordpress core blocks.

Also, in my example I used 2 houses (the required ones) for my custom style: to establish AND labelThe label can be used as text inside the Gutenberg UI and the setting can be used for the class name added to the block inside the is-style-{establish} structure.

I am ready to give you an explanation shortly on how you will be able to apply custom CSS for your block sorts. So keep on discovering.

Join some types of blocks

For each style you need to load you will need to use the register_block_style function. So for example, if you want to add more sorts to the Tick list block, it would be fine to do it like this:

/**
 * Join custom block sorts.
 */
function wpexplorer_register_block_styles() {

	// Inside of Tick list
	register_block_style(
		'core/checklist',
		[
			'name'  => 'list-inside',
			'label' => 'Inside',
		]
	);

	// Sq. Tick list
	register_block_style(
		'core/checklist',
		[
			'name'  => 'list-square',
			'label' => 'Square',
		]
	);

	// Checkmark checklist.
	register_block_style(
		'core/checklist',
		[
			'name'  => 'list-checkmark',
			'label' => 'Checkmark',
		]
	);

}
add_action( 'init', 'wpexplorer_register_block_styles' );

By adding this code you might see 3 additional sorts added to the checklist block as follows:

Writing leaner code (DRY code)

If you are registering a lot of types on your website, I suggest creating an array of the types you will be registering so you can loop through them. This way you don’t have to load register_block_style over and over again. This will probably keep your code lean and DRY sometimes.

This is an example of using an array to record multiple block orderings:

/**
 * Join custom block sorts.
 */
function wpexplorer_register_block_styles() {
	$sorts = [
		// List Styles
		'core/list' => [
			[
				'name'  => 'list-inside',
				'label' => 'Inside',
			],
			[
				'name'  => 'list-checkmark',
				'label' => 'Checkmark',
			]
		],
		// Button Sorts
		'core/button' => [
			[
				'name'  => 'button-three-d',
				'label' => 'Three-D',
			]
		],
	];
	foreach ( $sorts as $block => $style_props ) {
		register_block_style( $block, $style_props );
	}

}
add_action( 'init', 'wpexplorer_register_block_styles' );

See how much nicer it is? I would encourage you to always consider writing code in a DRY approach without repeating yourself.

Style block sorting with CSS

I have shown you some tips on how to save custom block sortings that you will simply be able to make a choice within the Gutenberg editor. On the other hand, this will not be if the truth is said explanation of why your block appears different. For that, you will need to add CSS for your website to focus on your custom sortings.

I’ve mentioned in the past that when you select a block style wordpress will insert the class name structure is-style-{establish} in the block elegance feature. So you will be able to use it to focus on the element.

Let’s say you want to upload a checklist style with a checkmark for your website, so you can save your style like this:

function wpexplorer_register_checkmark_list_style() {
	register_block_style(
		'core/checklist',
		[
			'name'  => 'list-checkmark',
			'label' => 'Checkmark',
		]
	);
}
add_action( 'init', 'wpexplorer_register_checkmark_list_style' );

Then you will definitely be able to add the following CSS to your website to use a test design with a checkmark in your checklist:

@counter-style checkmark {
  device: cyclic;
  symbols: "2713";
  suffix: " ";
}

.wp-block-list.is-style-list-checkmark {
  list-style: checkmark;
}

If you added your CSS to your theme’s style.css file, to WP’s custom CSS customizer, or via a plugin, then your checklist should be styled as it should be on the frontend.

On the other hand, we are working with Gutenberg, so you will need to add your CSS when you register your block to make sure the styling is applied in the backend as well.

To register your CSS along with your style, you can do it in two ways:

• Custom style sheet: You will pass the “style_handle” elements to your register_block_style function with a registered stylesheet setting. wordpress will routinely load the CSS file when the block is added to the submission content.
• Inline CSS: You will transfer the “inline_style” elements with the CSS you need to make your custom block style.

This is an example showing all the methods:

function wpexplorer_register_block_styles_with_css() {
	// Style that fairly so much stylesheet.
	register_block_style(
		'core/checklist',
		[
			'name'         => 'list-example-one',
			'label'        => 'Example One',
			'style_handle' => 'list-example-one-style-handle'
		]
	);
	// Style that gives inline CSS.
	register_block_style(
		'core/checklist',
		[
			'name'         => 'list-example-two',
			'label'        => 'Example Two',
			'inline_style' => '.wp-block-list.is-style-list-example-two { list-style: square; }',
		]
	);

}
add_action( 'init', 'wpexplorer_register_block_styles_with_css' );

In many cases, I would suggest using the inline_style properties. This might occasionally keep your website running faster, since it won’t want to load a third-party dependency. Usually, though, you’ll only need a few lines of CSS.

With this knowledge we will be able to go back to the checklist example and add the inline CSS as follows:

function wpexplorer_register_checkmark_list_style() {
	register_block_style(
		'core/checklist',
		[
			'name'         => 'list-checkmark',
			'label'        => 'Checkmark',
			'inline_style' => '@counter-style checkmark {system: cyclic;symbols: "2713";suffix: " ";}.wp-block-list.is-style-list-checkmark {list-style: checkmark;}'
		]
	);
}
add_action( 'init', 'wpexplorer_register_checkmark_list_style' );

Now you probably tried this checklist style, it must render beautifully in every Gutenberg editor and on the live website. Here is a screenshot taken in the backend.

Set a custom style as it is the default style

This is not something I would necessarily suggest as an alternative while you wanted it to be right to also set one of your custom types as the default. To make your style the default, simply transfer the is_default assets for your array such as:

register_block_style(
	'core/checklist',
	[
		'name'       => 'list-new-default',
		'label'      => 'New Default',
		'is_default' => true, // ADD THIS.
	]
);

Now whenever you insert the targeted block (in this case Checklist) you can use your custom style as the default style.

Crucial: When a practice style is ready as default, it means that no class name can be added to the block when it is determined.

Bonus: Remove a registered block style

Excellent enough, you are now qualified with custom block sorting. But then what happened when you wanted to remove an existing style from a block? Luckily, wordpress has a helper feature that we can use for this as well.

To remove an existing block style, use the unregister_block_style function. Here’s an example showing how to remove the ‘list-checkmark’ style from the ‘core/checklist’ block:

function wpexplorer_unregister_checkmark_list_style() {
	unregister_block_style( 'core/checklist', 'list-checkmark' );
}
add_action( 'init', 'wpexplorer_unregister_checkmark_list_style' );

unregister_block_style is most useful for removing sortings from a block theme that registers custom ones server-side.

Crucial: Using the unregister_block_style function will remove ONLY blocks that have been registered server-side using the register_block_style function. To remove sortings added client-side, you will need to use the Javascript Block API – read on to find out how!

Since you won’t be able to remove core wordpress blocks via PHP, I wanted to show you tactics you’ll be able to use via JS. The following example will remove the “outline” style from the Button block:

/**
 * Remove the outline block style.
 */
function wpexplorer_remove_outline_block_style() {
	// Join a "dummy" script so we will be able to add our JS inline.
	wp_register_script(
		'wpexplorer-unregister-block-styles',
		false,
		[ 'wp-blocks', 'wp-dom-ready', 'wp-edit-post' ],
	);

	// JS that removes the outline style from the button element.
	$script = "wp.domReady( () => {
		wp.blocks.unregisterBlockStyle( 'core/button', [ 'outline' ] );
	} );";

	// Load our JS.
	wp_enqueue_script( 'wpexplorer-unregister-block-styles' );
	wp_add_inline_script( 'wpexplorer-unregister-block-styles', $script );
}
add_action( 'admin_init', 'wpexplorer_remove_outline_block_style' );

Conclusion

Along with custom Gutenberg blocks it is super easy and also very useful. Right here on WPExplorer I register quite a few type blocks arranged in identical portions to lists, images and buttons. This allows me to transform the elements in another way in line with the context.
