bloginfo_rss()

💡 云策文档标注

概述

bloginfo_rss() 函数用于在 RSS 源中显示博客信息，它会自动去除标签并转换字符，确保内容适合在 RSS 中使用。该函数基于 get_bloginfo() 的参数来检索特定信息。

关键要点

函数 bloginfo_rss() 直接输出 RSS 容器中的博客信息，适用于 RSS 源显示。
参数 $show 为字符串，可选值参考 get_bloginfo()，如 'name' 表示博客标题，'description' 表示博客描述。
内部使用 get_bloginfo_rss() 获取信息，并通过 apply_filters() 钩子 'bloginfo_rss' 允许过滤输出。
与 get_bloginfo() 类似，但专为 RSS 设计，确保内容安全格式化。

代码示例

bloginfo_rss( 'name' );
bloginfo_rss( 'description' );

注意事项

如果需要检索信息用于其他用途而非直接输出，应使用 get_bloginfo() 函数。
