README

All the actions and filters from WordPress core in machine-readable JSON format.

Last updated for WordPress 6.7.

Installation

As a Composer package for use in PHP:

composer require wp-hooks/wordpress-core

As an npm package for use in JavaScript or TypeScript:
```
npm install @wp-hooks/wordpress-core
```

Usage in PHP

// Get hooks as JSON:
$actions_json = file_get_contents( 'vendor/wp-hooks/wordpress-core/hooks/actions.json' );
$filters_json = file_get_contents( 'vendor/wp-hooks/wordpress-core/hooks/filters.json' );

// Convert hooks to PHP:
$actions = json_decode( $actions_json, true )['hooks'];
$filters = json_decode( $filters_json, true )['hooks'];

// Search for filters matching a string:
$search = 'permalink';
$results = array_filter( $filters, function( array $hook ) use ( $search ) {
    return ( strpos( $hook['name'], $search ) !== false );
} );

var_dump( $results );

Usage in JavaScript

// Get hooks as array of objects:
const actions = require('@wp-hooks/wordpress-core/hooks/actions.json').hooks;
const filters = require('@wp-hooks/wordpress-core/hooks/filters.json').hooks;

// Search for actions matching a string:
const search = 'menu';
const results = actions.filter( hook => ( hook.name.match( search ) !== null ) );

console.log(results);

Importing in TypeScript

import { hooks as actions } from '@wp-hooks/wordpress-core/hooks/actions.json';
import { hooks as filters } from '@wp-hooks/wordpress-core/hooks/filters.json';

Interfaces for the components of the hooks can be imported too, if you need them:

import { Hooks, Hook, Doc, Tags, Tag } from '@wp-hooks/wordpress-core/interface';

Actions, Filters, and Schemas

The actions can be found in hooks/actions.json
The filters can be found in hooks/filters.json
The JSON schema can be found in hooks/schema.json
The TypeScript interfaces can be found in interface/index.d.ts

What can I use this for?

Anything that needs programmatic access to a list of available hooks, for example:

Regenerating the Hook Files

Change the roots/wordpress-full version in composer.json to the required WordPress version, or dev-main for nightly.

Install the dependencies:

npm i && composer i

Then run:

composer generate

Some scripts are available for checking the data:

Check everything:
```
npm run check
```

Find hooks with missing @since tags:

jq '.hooks[] | . as $d | .doc .tags | map(.name) | select( contains(["since"]) | not ) | $d' hooks/filters.json

jq '.hooks[] | . as $d | .doc .tags | map(.name) | select( contains(["since"]) | not ) | $d' hooks/actions.json

Find hooks with incorrect number of @param tags (not completely accurate, not sure why):

jq '.hooks[] | select( .args == ( .doc.tags | map(.name) | select( contains(["param"]) ) | length ) ) | .name' hooks/filters.json

jq '.hooks[] | select( .args == ( .doc.tags | map(.name) | select( contains(["param"]) ) | length ) ) | .name' hooks/actions.json

Hook Files for Plugins

Do you want the same hook files for your favourite plugins? The hook files in this repo are generated using wp-hooks-generator. It can generate hook files for WordPress plugins and themes as well as core.
