WordPress 5.9 was launched not too long ago delivery with Full Web site Enhancing (FSE), which permits utilizing blocks to create the structure for any web page within the web site (as was already doable to put in writing posts by way of the WordPress editor). Slowly however absolutely, blocks have gotten the principle person interface for creating WordPress websites.
Nevertheless, FSE doesn’t absolutely assist us configure WordPress websites. Whereas it already does present international settings by way of theme.json, that’s primarily for configuring the theme’s visible choices, resembling fonts, colours and paddings; for a theme or plugin’s invisible settings, often outlined as some entry within the wp_options desk, FSE provides no help (but).
Offering a settings web page for our themes and plugins that’s absolutely powered by blocks would offer a compelling person expertise. Via it, we might permit our customers to enter configuration values utilizing elements tailor-made to that kind of worth, resembling calendars to enter dates, interactive maps to enter location coordinates, sliders to select a quantity from inside a variety (resembling WooCommerce’s slider block to filter costs, displayed beneath), and so forth.
If we need to implement customized settings pages powered by blocks, in the meanwhile, we might want to implement a customized answer.
We might finally be capable to create a web page within the wp-admin that straight renders — and permits to work together with — the wanted blocks, as I not too long ago described in my current article, “Implications Of WordPress Becoming a member of The Block Protocol,” however that is at present solely into account — nowhere close to of it changing into a actuality (if it ever does).
A associated strategy that’s doable already at the moment, is to create a normal web page within the wp-admin that hundreds React and reuses the elements powering our blocks (that’s, the elements making up the blocks, however not the blocks themselves). Nevertheless, we might then be reinventing the wheel, to supply a GUI of decrease high quality than the one from the WordPress editor.
A greater strategy is to nonetheless use the WordPress editor, however altering its goal: as an alternative of making content material for a weblog put up, we will produce the configuration required for our plugin. This isn’t tough: as a result of the WordPress editor can energy customized put up sorts (CPTs), we will then create a selected CPT that fashions the required configuration, and have the plugin retrieve the saved information from throughout the customized put up content material.
On this situation, we should restrict which blocks can be found when enhancing the CPT and, fairly seemingly, lock them utilizing a predefined template. We should additionally watch out: the CPT content material is of personal use to the plugin, not supposed for public consumption, so we should ensure that it can’t be loaded on the public-facing web site.
That is the technique I employed for my WordPress plugin. On this write-up, I’ll describe my implementation (absolutely accessible within the the leoloso/PoP repo), which goals to leverage the WordPress editor to offer a fantastic person expertise for configuring our themes and plugins.
Overview Of The Outcomes
I’ll first give an summary of what’s the target: what performance I’ve deliberate for my plugin to help.
My plugin installs a GraphQL server that helps persevered queries. To retrieve information for a persevered question within the WordPress web site, I made a decision to create a brand new CPT referred to as persisted-query, and retrieve its information just by requesting its permalink.
The CPT makes use of the usual WordPress editor, powered by blocks:
Persevered queries may be configured in accordance with guidelines, involving entry management and HTTP caching. Choosing what guidelines should be utilized could possibly be accomplished throughout the persisted-query CPT itself, by way of some customized block. Nevertheless, totally different persevered queries will often require the identical algorithm, and if the set modifications, then all persevered queries would have to be up to date. That’s one thing I’d reasonably keep away from.
So, I made a decision to create a brand new CPT containing the chosen guidelines, which might then be utilized throughout totally different persevered queries. This CPT, referred to as schema-config, incorporates customized blocks to permit customers to pick which Entry Management Lists and Cache-Management Lists should be utilized:
The connection between a persevered question and its schema configuration should be supplied by the person. If the person had the Superior Customized Fields plugin put in, then offering the interface to create this relationship can be very simple. Nevertheless, I can not make such an assumption, or I’d be excluding many potential customers.
So, I needed to code my very own answer, for which I created a customized block that shows the record of all of the schema configurations, and had it embedded within the editor of the persevered question CPT:
On this answer, each CPTs are created utilizing the WordPress editor, and I can create customized blocks for every of them. The persisted-query CPT is public since customers should be capable to load it as to retrieve the response from the question. The schema-config CPT, although, is non-public; it should be accessed solely by the plugin, to retrieve configuration information used to render the persevered question.
Let’s discover subsequent the best way to implement it.
Creating The CPTs
To create a customized put up kind we use the register_post_type methodology:
operate create_persisted_query_cpt(): void
{
$labels = [
‘name’ => ‘Persisted queries’,
‘singular_name’ => ‘Persisted query’,
‘menu_name’ => ‘Persisted queries’,
‘name_admin_bar’ => ‘Persisted query’,
‘add_new’ => ‘Add New’,
‘add_new_item’ => ‘Add New Persisted query’,
‘new_item’ => ‘New Persisted query’,
‘edit_item’ => ‘Edit Persisted query’,
‘view_item’ => ‘View Persisted query’,
‘all_items’ => ‘All Persisted queries’,
‘search_items’ => ‘Search Persisted queries’,
‘parent_item_colon’ => ‘Parent Persisted query’,
‘not_found’ => ‘No Persisted queries found’,
‘not_found_in_trash’ => ‘No Persisted queries found in Trash’
];
$args = [
‘labels’ => $labels,
‘public’ => true,
‘show_in_rest’ => true,
‘rewrite’ => [‘slug’ => ‘persisted-query’],
];
register_post_type(‘persisted-query’, $args);
}
add_action(‘init’, ‘create_persisted_query_cpt’);
The code above applies to creating the general public CPT. To create a personal CPT, we’d like solely swap the general public argument to false; argument show_in_rest should nonetheless be true, as to have the ability to retrieve its information by way of the WP REST API (which powers the blocks within the WordPress editor):
operate create_schema_config_cpt(): void
{
$labels = [
‘name’ => ‘Schema configurations’,
‘singular_name’ => ‘Schema configuration’,
// All the rest…
];
$args = [
‘public’ => false,
‘show_in_rest’ => true,
// …
];
}
add_action(‘init’, ‘create_schema_config_cpt’);
For finer management, we will additionally set the worth of the opposite arguments, together with: exclude_from_search, publicly_queryable, show_ui, show_in_nav_menus, show_in_menu and show_in_admin_bar.
As a aspect be aware, please discover how, as a result of effort to keep away from introducing breaking modifications in every new launch of WordPress (totally on the PHP aspect; the JS aspect powering the WordPress editor has undergone some instability), previous guides on the subject, resembling this Smashing article from 2015, will nonetheless be largely updated. The show_in_rest argument (and in addition template, used afterward) is just not defined there however, in any other case, all the pieces else nonetheless works. And the CPT will by default use the brand new WordPress editor, as an alternative of the “Basic” editor.
Creating The Customized Block
By now, I’ve created my private and non-private CPTs. The following step is to hyperlink them up, by embedding a customized block that lists all entries from the non-public CPT schema-config within the editor for the general public CPT persisted-query.
The best method to arrange a brand new block is thru @wordpress/create-block, which by default generates a brand new WordPress plugin containing a single block. If we have already got the plugin, after operating command npx @wordpress/create-block my-block, we will copy the PHP code for registering the block, and the JS/CSS recordsdata for the block, copy them to our plugin and discard all the pieces else.
I did this to create my customized block, of kind graphql-api/schema-configuration:
import { __ } from ‘@wordpress/i18n’;
registerBlockType( ‘graphql-api/schema-configuration’, {
title: __( ‘Schema Configuration’, ‘graphql-api’ ),
description: __( ‘Choose the Schema Configuration for the GraphQL persevered question’, ‘graphql-api’ ),
icon: ‘admin-users’,
// …
} );
The customized block should be given the next conduct.
First: It should retailer the ID of the chosen schema-config CPT entry, for which I register an attribute schemaConfiguration of kind integer:
registerBlockType( ‘graphql-api/schema-configuration’, {
// …
/**
* 1. Retailer the ID of the chosen schema configuration entry
*/
attributes: {
schemaConfiguration: {
kind: ‘integer’,
default: 0,
},
},
} );
Second: It should solely be accessible to the persisted-query CPT, and nowhere else.
For this, I outline the inserter attribute to false, making the block unavailable within the editor, and it should be explicitly set by way of a template (extra on this afterward).
registerBlockType( ‘graphql-api/schema-configuration’, {
// …
/**
* 2. The block can solely be accessible to the “persisted-query” CPT
*/
helps: {
inserter: false,
},
} );
Third: Don’t render the configuration.
This feature shouldn’t matter a lot, as a result of the block shouldn’t be printed on display screen. Its solely objective is to retailer configuration to energy another performance, resembling rendering a persevered question.
Nevertheless, simply to be on the secure aspect and keep away from unintended leaks, we’d reasonably not print the configuration information. Extra for the reason that WordPress editor shops block information inside an HTML remark, like this:
This remark could also be printed on the web page with out us being conscious of it. Whereas displaying the chosen schema configuration ID is just not harmful, we might as nicely retailer delicate configuration information, resembling API keys.
Then, for peace of thoughts, let’s produce some secure content material within the block’s save methodology:
registerBlockType( ‘graphql-api/schema-configuration’, {
// …
/**
* 3. Do not render the configuration
*/
save() {
return <p>You shouldn’t be studying this! 😈</p>;
},
} );
Final: The block should retrieve the record of the schema configuration entries, permit the person to pick one by displaying them on appropriate enter management, and persist the chosen entry within the DB.
This merchandise would require a few steps:
Retrieving the schema configuration entries from the server.
Creating elements to render the block.
To retrieve the record of entries from the schema-config CPT, the block makes use of a retailer which works by executing a GraphQL question towards the server:
receiveSchemaConfigurations,
setSchemaConfigurations,
} from ‘./action-creators’;
export const FETCH_SCHEMA_CONFIGURATIONS_GRAPHQL_QUERY = question GetSchemaConfigurations {
schemaConfigurations {
id
title
}
}
export default {
* getSchemaConfigurations() ,
};
To create elements to render the block, we will conveniently use any React element to energy our blocks, together with these freely accessible in npm. I took benefit of this and imported the fantastic Choose element provided by the react-select bundle, as to permit the person to select the schema configuration entry via a handsome choose enter.
I created the hierarchy of elements composing one another as to make the code reusable. On the bottom-most layer there’s <Choose />, which is wrapped by a customized SelectCard element, which is itself wrapped by a top-level SchemaConfigurationSelectCard element. This latter element shows a choose enter with all of the schema configuration entries, and onChange will persist the worth of the chosen entry to the DB:
import { compose, withState } from ‘@wordpress/compose’;
import { __ } from ‘@wordpress/i18n’;
import { SelectCard } from ‘@graphqlapi/elements’;
const SchemaConfigurationSelectCard = ( props ) => {
const {
schemaConfigurations,
attributes: {
schemaConfiguration
}
} = props;
const schemaConfigurationOptions = schemaConfigurations.map( schemaConfiguration => (
{
label: schemaConfiguration.title,
worth: schemaConfiguration.id,
}
) );
const metaOptions = [
{
label: 🟡 ${ __(‘Default’, ‘graphql-api’) },
value: 0,
},
{
label: ❌ ${ __(‘None’, ‘graphql-api’) },
value: -1,
},
];
const groupedOptions = [
{
label: ”,
options: metaOptions,
},
{
label: ”,
options: schemaConfigurationOptions,
},
];
const selectedOptions = schemaConfigurationOptions.filter( choice => choice.worth == schemaConfiguration );
const defaultValue = selectedOptions[0];
return (
<SelectCard
{ …props }
isMulti={ false }
choices={ groupedOptions }
defaultValue={ defaultValue }
onChange={ chosen => setAttributes( {
[‘schemaConfiguration’]: chosen.worth
} ) }
/>
);
}
export default compose( [
withState( {
label: __(‘Schema configuration’, ‘graphql-api’),
} ),
withSelect( ( select ) => {
const {
getSchemaConfigurations,
} = select ( ‘graphql-api/schema-configuration’ );
return {
schemaConfigurations: getSchemaConfigurations(),
};
} ),
] )( SchemaConfigurationSelectCard );
Lastly, I embedded <SchemaConfigurationSelectCard /> throughout the block’s edit methodology:
registerBlockType( ‘graphql-api/schema-configuration’, {
// …
/**
* 4. Show all schema configuration entries, and persist the chosen entry to DB
*/
edit(props) {
const { className } = props;
return (
<div class={ className }>
<SchemaConfigurationSelectCard
{ …props }
/>
</div>
)
},
} );
The ensuing index.js file is this one:
import { __ } from ‘@wordpress/i18n’;
import SchemaConfigurationSelectCard from ‘./schema-configuration’;
registerBlockType( ‘graphql-api/schema-configuration’, {
title: __( ‘Schema Configuration’, ‘graphql-api’ ),
description: __( ‘Choose the Schema Configuration for the GraphQL question’, ‘graphql-api’ ),
icon: ‘admin-users’,
/**
* 1. Retailer the ID of the chosen schema configuration entry
*/
attributes: {
schemaConfiguration: {
kind: ‘integer’,
default: 0,
},
},
/**
* 2. The block can solely be accessible to the “persisted-query” CPT
*/
helps: {
inserter: false,
},
/**
* 3. Do not render the configuration
*/
save() {
return <p>You shouldn’t be studying this! 🤔</p>;
},
/**
* 4. Show all schema configuration entries, and persevered the chosen entry to DB
*/
edit(props) {
const { className } = props;
return (
<div class={ className }>
<SchemaConfigurationSelectCard
{ …props }
/>
</div>
)
},
} );
Embedding The Customized Block Inside The Public CPT
By now, we have now created the private and non-private CPTs, and the customized block that hyperlinks them collectively. Subsequent, we have to embed the customized block throughout the public CPT.
The schema configuration is necessary, and it should be set solely as soon as. Therefore, it is mindless for the block to be added by way of the inserter within the editor, which might permit the person to not insert the block, or insert it a number of instances. For that motive, earlier on we outlined attribute inserter as false when registering the block.
As an alternative, we’ll “lock” a predefined template within the editor for the CPT, which specifies which blocks are for use. For the persevered question, there can be two blocks:
The GraphiQL consumer (applied right here),
The “schema configuration” block.
To do that, we will outline the template already when registering the put up kind, or by setting properties template and template_lock from the CPT object:
operate register_persisted_query_template(): void
{
$post_type_object = get_post_type_object( ‘persisted-query’ );
$post_type_object->template = [
[‘graphql-api/graphiql’],
[‘graphql-api/schema-configuration’],
];
$post_type_object->template_lock = ‘all’;
}
add_action( ‘init’, ‘register_persisted_query_template’ );
Now, when enhancing a persevered question, the predefined blocks will seem within the order and amount specified, and be able to be crammed by the person.
Retrieving The CPT Configuration Knowledge
By now, the system is generally in place: we have now created our private and non-private CPTs and linked them each collectively by way of a customized block. By this stage, our plugin customers can create schema configuration entries, and choose the required one when making a persevered question. Because of this, we can have all this information saved within the database, beneath the corresponding customized put up entry.
Lastly, we have to render the persevered question dynamically, making use of the schema configuration. Let’s see the best way to learn the configuration information in our PHP code.
We will entry the schema configuration ID within the template persisted-query.php (or anyplace the CPT can be rendered). First, we parse the content material of the persevered question by way of parse_blocks, as to have entry to the block information:
$persistedQueryBlocks = parse_blocks($persistedQueryObject->post_content);
To retrieve the “schema-configuration” block, we should filter it by its title:
$schemaConfigurationBlock = null;
foreach ($persistedQueryBlocks as $block) {
if ($block[‘blockName’] === ‘graphql-api/schema-configuration’) {
// We discovered the block
$schemaConfigurationBlock = $block;
break;
}
}
As soon as we have now the block, we will entry its information beneath attrs and the title of the attribute we selected to retailer the information when registering the block, which was “schemaConfiguration”:
We have now now retrieved the chosen schema configuration ID. Repeating the identical sequence, we will retrieve the block information saved on this customized put up entry, which is our non-public configuration information.
The schema configuration CPT shops the chosen entry management entries beneath block schema-config-access-control-lists, and the chosen cache management entries beneath block schema-config-cache-control-lists:
$schemaConfigurationBlocks = parse_blocks($schemaConfigurationObject->post_content);
$accessControlBlock = $cacheControlBlock = null;
foreach ($schemaConfigurationBlocks as $block) {
if ($block[‘blockName’] === ‘graphql-api/schema-config-access-control-lists’) {
$accessControlBlock = $block;
} elseif ($block[‘blockName’] === ‘graphql-api/schema-config-cache-control-lists’) {
$cacheControlBlock = $block;
}
}
// Retrieve the saved configuration from the non-public CPT
$accessControlLists = $accessControlBlock[‘attrs’][‘accessControlLists’];;
$cacheControlLists = $cacheControlBlock[‘attrs’][‘cacheControlLists’];
Lastly, we have now retrieved the non-public configuration information, which we will use to determine the best way to render the persevered question (how my plugin then goes on to render this response is just not vital to the subject of this text):
// Do one thing with the configuration information
// …
/**
ffffffffffffffff iiii
f::::::::::::::::f i::::i
f::::::::::::::::::f iiii
f::::::fffffff:::::f
f:::::f ffffffiiiiiiinnnn nnnnnnnn
f:::::f i:::::in:::nn::::::::nn
f:::::::ffffff i::::in::::::::::::::nn
f::::::::::::f i::::inn:::::::::::::::n
f::::::::::::f i::::i n:::::nnnn:::::n
f:::::::ffffff i::::i n::::n n::::n
f:::::f i::::i n::::n n::::n
f:::::f i::::i n::::n n::::n
f:::::::f i::::::i n::::n n::::n
f:::::::f i::::::i n::::n n::::n
f:::::::f i::::::i n::::n n::::n
fffffffff iiiiiiii nnnnnn nnnnnn
*/
Tadaaaaa! We have now created a public customized put up kind that retrieves configuration information from a personal customized put up kind, and each CPTs are powered by blocks. Success! 🙏
Wrapping Up
If we need to configure our plugins utilizing blocks, for the reason that recently-released Full Web site Enhancing characteristic can not but be used to create settings pages, we should then implement a customized answer.
On this article, I described one answer, primarily based on creating a personal customized put up kind to retailer the configuration information, and utilizing the WordPress editor because the interface to fill this information.
Because of this, we will present a compelling expertise for our customers, due to the editor’s WYSIWYG, and the power of blocks to offer controls that swimsuit the kind of content material that should be supplied, resembling calendars, sliders, maps, or every other format.
