acf/schema/enabled_post_types

Filter the list of post types that have JSON-LD output enabled.

Description

This filter allows you to programmatically enable JSON-LD output for post types without using the admin UI. This is useful for enabling JSON-LD on post types registered by other plugins or for dynamically controlling which post types output structured data.

Changelog

• Added in version 6.8.0

Parameters

apply_filters( 'acf/schema/enabled_post_types', $post_types );

• $post_types (array) Array of post type names that have JSON-LD enabled via the admin UI

Return

(array) The modified array of post type names.

Example

This example enables JSON-LD output for WooCommerce products.

/**
 * Enable JSON-LD for WooCommerce products.
 *
 * @param array $post_types Array of enabled post type names.
 * @return array Modified array of post type names.
 */
function my_acf_schema_enable_products( $post_types ) {
    $post_types[] = 'product';
    return $post_types;
}
add_filter( 'acf/schema/enabled_post_types', 'my_acf_schema_enable_products' );

This example conditionally enables JSON-LD based on environment.

/**
 * Only enable JSON-LD on production.
 *
 * @param array $post_types Array of enabled post type names.
 * @return array Modified array of post type names.
 */
function my_acf_schema_production_only( $post_types ) {
    if ( wp_get_environment_type() !== 'production' ) {
        return array(); // Disable all JSON-LD output
    }
    return $post_types;
}
add_filter( 'acf/schema/enabled_post_types', 'my_acf_schema_production_only' );
