概述

get_to_ping 是一个 WordPress 过滤器，用于修改待 ping 的 URL 列表。它允许开发者在 WordPress 自动 ping 之前调整 URL 数组，但回调函数不应直接执行 ping 操作。

回调函数必须返回一个 URL 数组，否则可能导致代码中断或插件错误。

📄 原文内容

Filters the list of URLs yet to ping for the given post.

Callback functions applied to this filter should not ping the URLs. Instead, they may modify the array of URLs to be pinged, and WordPress will ping them automatically.
Note that each of the filter callback functions must return an array of URLs after it is finished processing. Otherwise, any code using the $to_ping array will break and other plugins also filtering the $to_ping array may generate errors.

return apply_filters( 'get_to_ping', $to_ping );
