Eg, 'pillow -sofa' will * return posts containing 'pillow' but not 'sofa'. The * character used for exclusion can be modified using the * the 'wp_query_search_exclusion_prefix' filter. * @type string[] $search_columns Array of column names to be searched. Accepts 'post_title', * 'post_excerpt' and 'post_content'. Default empty array. * @type int $second Second of the minute. Default empty. Accepts numbers 0-59. * @type bool $sentence Whether to search by phrase. Default false. * @type bool $suppress_filters Whether to suppress filters. Default false. * @type string $tag Tag slug. Comma-separated (either), Plus-separated (all). * @type int[] $tag__and An array of tag IDs (AND in). * @type int[] $tag__in An array of tag IDs (OR in). * @type int[] $tag__not_in An array of tag IDs (NOT in). * @type int $tag_id Tag id or comma-separated list of IDs. * @type string[] $tag_slug__and An array of tag slugs (AND in). * @type string[] $tag_slug__in An array of tag slugs (OR in). unless 'ignore_sticky_posts' is * true.

Default false. * @type bool $lazy_load_term_meta Whether to lazy-load term meta. Setting to false will * disable cache priming for term meta, so that each * get_term_meta() call will hit the database. * Defaults to the value of `$update_post_term_cache`. * @type int $w The week number of the year.

It requires three steps: * * 1. Hook into the `wp_abilities_api_init` action. * 2. Call `wp_register_ability()` with a namespaced name and configuration. * 3. Provide execute and permission callbacks. * * Example: * * function my_plugin_register_abilities(): void { * wp_register_ability( * 'my-plugin/analyze-text', * array( * 'label' => __( 'Analyze Text', 'my-plugin' ), * 'description' => __( 'Performs sentiment analysis on provided text.', 'my-plugin' ), * 'category' => 'text-processing', * 'input_schema' => array( * 'type' => 'string', * 'description' => __( 'The text to be analyzed.', 'my-plugin' ), * 'minLength' => 10, * 'required' => true, * ), * 'output_schema' => array( * 'type' => 'string', * 'enum' => array( 'positive', 'negative', 'neutral' ), * 'description' => __( 'The sentiment result: positive, negative, or neutral.', 'my-plugin' ), * 'required' => true, * ), * 'execute_callback' => 'my_plugin_analyze_text', * 'permission_callback' => 'my_plugin_can_analyze_text', * 'meta' => array( * 'annotations' => array( * 'readonly' => true, * ), * 'show_in_rest' => true, * ), * ) * ); * } * add_action( 'wp_abilities_api_init', 'my_plugin_register_abilities' ); * * ### Naming Conventions * * Ability names must follow these rules: * * - Include a namespace prefix (e.g., `my-plugin/my-ability`). * - Use only lowercase alphanumeric characters, dashes, and forward slashes. * - Use descriptive, action-oriented names (e.g., `process-payment`, `generate-report`). * * ### Categories * * Abilities must be organized into categories. Ability categories provide better * discoverability and must be registered before the abilities that reference them: * * function my_plugin_register_categories(): void { * wp_register_ability_category( * 'text-processing', * array( * 'label' => __( 'Text Processing', 'my-plugin' ), * 'description' => __( 'Abilities for analyzing and transforming text.', 'my-plugin' ), * ) * ); * } * add_action( 'wp_abilities_api_categories_init', 'my_plugin_register_categories' ); * * ### Input and Output Schemas * * Schemas define the expected structure, type, and constraints for ability inputs * and outputs using JSON Schema syntax. They serve two critical purposes: automatic * validation of data passed to and returned from abilities, and self-documenting * API contracts for developers. * * WordPress implements a validator based on a subset of the JSON Schema Version 4 * specification (https://json-schema.org/specification-links.html#draft-4). * For details on supported JSON Schema properties and syntax, see the * related WordPress REST API Schema documentation: * https://developer.wordpress.org/rest-api/extending-the-rest-api/schema/#json-schema-basics * * Defining schemas is mandatory when there is a value to pass or return. * They ensure data integrity, improve developer experience, and enable * better documentation: * * 'input_schema' => array( * 'type' => 'string', * 'description' => __( 'The text to be analyzed.', 'my-plugin' ), * 'minLength' => 10, * 'required' => true, * ), * 'output_schema' => array( * 'type' => 'string', * 'enum' => array( 'positive', 'negative', 'neutral' ), * 'description' => __( 'The sentiment result: positive, negative, or neutral.', 'my-plugin' ), * 'required' => true, * ), * * ### Callbacks * * #### Execute Callback * * The execute callback performs the ability's core functionality. It receives * optional input data and returns either a result or `WP_Error` on failure. * * function my_plugin_analyze_text( string $input ): string|WP_Error { * $score = My_Plugin::perform_sentiment_analysis( $input ); * if ( is_wp_error( $score ) ) { * return $score; * } * return My_Plugin::interpret_sentiment_score( $score ); * } * * #### Permission Callback * * The permission callback determines whether the ability can be executed. * It receives the same input as the execute callback and must return a * boolean or `WP_Error`. Common use cases include checking user capabilities, * validating API keys, or verifying system state: * * function my_plugin_can_analyze_text( string $input ): bool|WP_Error { * return current_user_can( 'edit_posts' ); * } * * ### REST API Integration * * Abilities can be exposed through the REST API by setting `show_in_rest` * to `true` in the meta configuration: * * 'meta' => array( * 'show_in_rest' => true, * ), * * This allows abilities to be invoked via HTTP requests to the WordPress REST API. * * @since 6.9.0 * * @see WP_Abilities_Registry::register() * @see wp_register_ability_category() * @see wp_unregister_ability() * * @param string $name The name of the ability. Must be a namespaced string containing * a prefix, e.g., `my-plugin/my-ability`. Can only contain lowercase * alphanumeric characters, dashes, and forward slashes. * @param array $args { * An associative array of arguments for configuring the ability. * * @type string $label Required. The human-readable label for the ability. * @type string $description Required. A detailed description of what the ability does * and when it should be used. * @type string $category Required. The ability category slug this ability belongs to. * The ability category must be registered via `wp_register_ability_category()` * before registering the ability. * @type callable $execute_callback Required. A callback function to execute when the ability is invoked. * Receives optional mixed input data and must return either a result * value (any type) or a `WP_Error` object on failure. * @type callable $permission_callback Required. A callback function to check permissions before execution. * Receives optional mixed input data (same as `execute_callback`) and * must return `true`/`false` for simple checks, or `WP_Error` for * detailed error responses. * @type array $input_schema Optional. JSON Schema definition for validating the ability's input. * Must be a valid JSON Schema object defining the structure and * constraints for input data.
