我已经非常广泛地使用了自定义块选项。我为自定义帖子类型启用编辑器，但使用自定义模板template_lock 设置为true:

\'template\' => array(
    array(\'pb/custom-block-name\'),
),
\'template_lock\' => true

然后我使用allowed_block_types_all 筛选以仅允许post类型的自定义块：

function pb_allowed_block_types($allowed_block_types, $block_editor_context) {
    if (!$block_editor_context->post || $block_editor_context->post->post_type !== \'custom_post_type\') {
        return $allowed_block_types;
    }

    return array(
        \'pb/custom-block-name\',
    );
}
add_filter(\'allowed_block_types_all\', \'pb_allowed_block_types\', 10, 2);

最后，我使用useEntityProp 要获取和设置元，请执行以下操作：

import { __ } from \'@wordpress/i18n\';
import { useSelect } from \'@wordpress/data\';
import { useEntityProp } from \'@wordpress/core-data\';

const Edit = (props) => {
    const postType = useSelect((select) => (
        select(\'core/editor\').getCurrentPostType()
    ));

    const [meta, setMeta] = useEntityProp(\'postType\', postType, \'meta\');

    return (
        <TextControl
            label={ __(\'Label\', \'pb\') }
            value={ meta._pb_meta_slug }
            onChange={ (value) => setMeta({_pb_meta_slug: value}) }
        />
    );
};

确保您使用register_post_meta 要为自定义帖子类型注册所有帖子元，否则将无法保存：

register_post_meta(\'custom_post_type\', \'_pb_meta_slug\', array(
    \'type\' => \'string\',
    \'single\' => true,
    \'auth_callback\' => function() {
        return current_user_can(\'edit_posts\');
    },
    \'show_in_rest\' => true,
));
