Peer categories are categories that all share the same category parent. For example, assume your category structure is hierarchical and looks like this: ``` Vegetables |-- Leafy | |-- Broccoli | |-- Bok Choy | |-- Celery |-- Fruiting | |-- Bell Pepper | |-- Cucumber | |-- Pumpkin |-- Podded | |-- Chickpea | |-- Lentil | |-- Soybean ``` If you directly assigned the categories “Fruiting” and “Pumpkin” to a post, `peer_categories()` would return a list that consists of: “Bell Pepper”, “Cucumber”, and “Pumpkin”. Notice that since “Fruiting” was a parent to a directly assigned category, it and its peers are not included in the list. If only “Fruiting” were selected as a category, then “Leafy”, “Fruiting”, and “Podded” would have been listed. By default, categories are listed as an HTML list. The first argument to the template tag allows you to define a custom separator, e.g. to have a simple comma-separated list of peer categories: ``. As with categories listed via `the_category()`, categories that are listed are presented as links to the respective category’s archive page. Example usage (based on preceding example): * `` Outputs something like: ``` ``` * `` Outputs something like: ``` Bell Pepper, Cucumber, Pumpkin ``` Links: [Plugin Homepage](https://coffee2code.com/wp-plugins/peer-categories/) | [Plugin Directory Page](https://wordpress.org/plugins/peer-categories/) | [GitHub](https://github.com/coffee2code/peer-categories/) | [Author Homepage](https://coffee2code.com) ### Developer Documentation Developer documentation can be found in [DEVELOPER-DOCS.md](https://github.com/coffee2code/peer-categories/blob/master/DEVELOPER-DOCS.md). That documentation covers the template tags and hooks provided by the plugin. As an overview, these are the template tags provided by the plugin: * `c2c_peer_categories()` : Outputs the peer categories. * `c2c_get_peer_categories_list()` : Returns the list of peer categories. * `c2c_get_peer_categories()` : Returns the list of peer categories for the specified post. These are the hooks provided by the plugin: * `c2c_peer_categories` _(action)_, `c2c_get_peer_categories_list`, `c2c_get_peer_categories`_( filters)_ : Allows for an alternative approach to safely invoke each of the identically named functions in such a way that if the plugin were deactivated or deleted, then your calls to the functions won’t cause errors on your site. * `c2c_peer_categories_list` _(filter)_ : Customizes the return value of the ` c2c_peer_categories_list()` function. * `c2c_get_peer_categories_omit_ancestors` _(filter)_ : Customizes the function argument indicating if ancestor categories of all directly assigned categories( even if directly assigned themselves) should be omitted from the return list of categories. ## 安装 1. Install via the built-in WordPress plugin installer. Or install the plugin code inside the plugins directory for your site (typically `/wp-content/plugins/`). 2. Activate the plugin through the ‘Plugins’ admin menu in WordPress 3. Optional: Add filters for ‘c2c_peer_categories_list’ to filter peer category listing 4. Use the template tag `` in a theme template somewhere inside “the loop” ## 常见问题 ### Why isn’t an assigned category for the post showing up in the ‘c2c_peer_categories()’ listing? If an assigned category is the parent for one or more other assigned categories for the post, then the category parent is not included in the listing. Only peers to the lowest-level assigned categories are considered. ### Does this plugin have unit tests? Yes. The tests are not packaged in the release .zip file or included in plugins. svn.wordpress.org, but can be found in the [plugin’s GitHub repository](https://github.com/coffee2code/peer-categories/). ## 评价 此插件暂无评价。 ## 贡献者及开发者 「Peer Categories」是开源软件。 以下人员对此插件做出了贡献。 贡献者 * [ Scott Reilly ](https://profiles.wordpress.org/coffee2code/) [帮助将「Peer Categories」翻译成简体中文。](https://translate.wordpress.org/projects/wp-plugins/peer-categories) ### 对开发感兴趣吗? 您可以[浏览代码](https://plugins.trac.wordpress.org/browser/peer-categories/)，查看 [SVN仓库](https://plugins.svn.wordpress.org/peer-categories/)，或通过[RSS](https://plugins.trac.wordpress.org/log/peer-categories/?limit=100&mode=stop_on_copy&format=rss) 订阅[开发日志](https://plugins.trac.wordpress.org/log/peer-categories/)。 ## 更新日志 #### 2.3.1 (2025-04-21) * Change: Note compatibility through WP 6.8+ * Change: Note compatibility through PHP 8.3+ * Change: Update copyright date (2025) * Unit tests: - Change: Explicitly define return type for overridden method #### 2.3 (2024-08-28) Highlights: This minor release prevents translations from containing unintended markup, removes unnecessary functionality within `c2c_get_peer_categories()`, notes compatibility through WP 6.6+, removes unit tests from release packaging, and updates copyright date (2024).
