概述

wp_delete_auto_drafts() 函数用于删除超过7天的自动草稿文章。它通过数据库查询和 wp_delete_post() 强制删除来实现清理功能。

关键要点

  • 函数自动删除状态为 'auto-draft' 且创建时间超过7天的文章
  • 使用 wpdb::get_col() 查询符合条件的文章ID
  • 通过 wp_delete_post( $delete, true ) 强制删除文章，不进入回收站
  • 该函数自 WordPress 3.4.0 版本引入

代码示例

function wp_delete_autodraft() {
    global $wpdb;
 
    // Delete auto-drafts.
    $old_posts = $wpdb->get_col( "SELECT ID FROM $wpdb->posts WHERE post_status = 'auto-draft'" );
    foreach ( (array) $old_posts as $delete ) {
        // Force delete.
        wp_delete_post( $delete, true );
    }
}
add_action( 'init', 'wp_delete_autodraft' );

注意事项

用户贡献的笔记提供了一个自定义函数示例，可以立即删除所有自动草稿，无需等待7天，但需谨慎使用以避免意外数据丢失。
