pre_ping
云策文档标注
概述
pre_ping 是一个 WordPress 动作钩子，在文章中的链接被 pingback 之前触发。它允许开发者修改待检查的链接列表，常用于自定义 pingback 行为。
关键要点
- pre_ping 钩子在 pingback 过程中触发，用于处理文章中的链接。
- 参数包括 $post_links（待检查链接数组，引用传递）、$pung（已 ping 链接数组，引用传递）和 $post_id（文章 ID）。
- 通过此钩子可以过滤或修改链接，例如禁用来自自身站点的 pingbacks。
代码示例
/**

*/
add_action( 'pre_ping', function ( &$post_links, &$pung, int $post_ID ) {
foreach ( $post_links as $key => $link ) {
if ( 0 === strpos( $link, home_url() ) ) {
unset( $post_links[ $key ] );
}
}
}, 10, 3 );
