Title: Random File Author: Scott Reilly Published: 2004 年 12 月 21 日 Last modified: 2025 年 4 月 8 日 --- 搜索插件 ![](https://ps.w.org/random-file/assets/banner-772x250.png?rev=837026) ![](https://ps.w.org/random-file/assets/icon-128x128.png?rev=1091134) # Random File 作者：[Scott Reilly](https://profiles.wordpress.org/coffee2code/) [下载](https://downloads.wordpress.org/plugin/random-file.2.0.1.zip) * [详情](https://cn.wordpress.org/plugins/random-file/#description) * [评价](https://cn.wordpress.org/plugins/random-file/#reviews) * [安装](https://cn.wordpress.org/plugins/random-file/#installation) * [开发进展](https://cn.wordpress.org/plugins/random-file/#developers) [支持](https://wordpress.org/support/plugin/random-file/) ## 描述 This plugin provides template tags that allow you to retrieve the name, path (relative or absolute), url, or fully marked-up link to a randomly chosen file or files in a specified directory. Arguments to the functions permit you to limit what file(s) can be randomly selected based on a given set of file extensions. You can also explicitly specify files that should not be randomly selected. This functionality can be useful for displaying random images/logos or including text from random files onto your site (writing excerpts, multi-line quotes, etc). Other ideas: random ads, random CSS files, random theme template selection. Notes: * If you want to actually display the name of the random file, be sure to ‘echo’ the results: * Unless you limit the file search to only include a particular extension (via ` $extensions` argument), all files in the specified `$dir` will be under consideration for random selection * Can be run inside or outside of “the loop” Links: [Plugin Homepage](https://coffee2code.com/wp-plugins/random-file/) | [Plugin Directory Page](https://wordpress.org/plugins/random-file/) | [GitHub](https://github.com/coffee2code/random-file/) | [Author Homepage](https://coffee2code.com) ### Developer Documentation Developer documentation can be found in [DEVELOPER-DOCS.md](https://github.com/coffee2code/random-file/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_random_file()` : Retrieves the name of a random file from a specified directory and returns information based on the file. * `c2c_random_files()` : Retrieves the name, path, or link to a specified number of randomly chosen files in a specified directory. These are the hooks provided by the plugin: * `c2c_random_file` : Filter to safely invoke `c2c_random_file()` in such a way that if the plugin were deactivated or deleted, then your calls to the function won’t cause errors in your site. * `c2c_random_files` : Filter to safely invoke `c2c_random_files()` in such a way that if the plugin were deactivated or deleted, then your calls to the function won’t cause errors in your site. ## 安装 1. Install via the built-in WordPress plugin installer. Or download and unzip `random- file.zip` inside the plugins directory for your site (typically `wp-content/plugins/`) 2. Activate the plugin through the ‘Plugins’ admin menu in WordPress 3. Make use of the `c2c_random_file()` or `c2c_random_files()` template function in your code or template (see examples below). ## 常见问题 ### Does this plugin do dynamic random rotation within a loaded page (i.e. randomly rotating images within a loaded page)? No. This plugin only selects a random file when the page is loaded. Once loaded, it does not currently add any dynamic functionality to automatically retrieve another random file on its own. ### Does this plugin include 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/random-file/). ## 评价 此插件暂无评价。 ## 贡献者及开发者 「Random File」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「Random File」翻译成简体中文。](https://translate.wordpress.org/projects/wp-plugins/random-file) ### 对开发感兴趣吗? 您可以[浏览代码](https://plugins.trac.wordpress.org/browser/random-file/)，查看[SVN仓库](https://plugins.svn.wordpress.org/random-file/)， 或通过[RSS](https://plugins.trac.wordpress.org/log/random-file/?limit=100&mode=stop_on_copy&format=rss) 订阅[开发日志](https://plugins.trac.wordpress.org/log/random-file/)。 ## 更新日志 #### 2.0.1 (2025-04-08) * Fix: Fix typos in documentation * Change: Note compatibility through WP 6.8+ * Change: Update copyright date (2025) * Unit tests: - Change: Switch uses of `assertRegExp()` to `assertMatchesRegularExpression()` for future PHPUnit 10 compatibility - Change: Explicitly define return type for overridden method #### 2.0 (2024-08-13) Highlights: This minor update features improved randomization of file selection, adds support for the extensions argument to be an array, notes compatibility through WP 6.6+, removes unit tests from release packaging, updates copyright date (2024), and other code improvements and minor changes.
