我的问题是，有没有办法将post\\u作者添加到wp\\u insert\\u附件中？我在文档中找不到这一点。我需要的附件有相同的作者id作为该职位。目前它采用管理员的id。

有时，法典或出版的文件并不能说明全部情况。如果您不了解函数是如何工作的，直接转到源代码总是更好的。如果查看PHP文档块wp_insert_attachment() 你会找到你正在寻找的答案。

/**
 * Insert an attachment.
 *
 * If you set the \'ID\' in the $object parameter, it will mean that you are
 * updating and attempt to update the attachment. You can also set the
 * attachment name or title by setting the key \'post_name\' or \'post_title\'.
 *
 * You can set the dates for the attachment manually by setting the \'post_date\'
 * and \'post_date_gmt\' keys\' values.
 *
 * By default, the comments will use the default settings for whether the
 * comments are allowed. You can close them manually or keep them open by
 * setting the value for the \'comment_status\' key.
 *
 * The $object parameter can have the following:
 *     \'post_status\'   - Default is \'draft\'. Can not be overridden, set the same as parent post.
 *     \'post_type\'     - Default is \'post\', will be set to attachment. Can not override.
 *     \'post_author\'   - Default is current user ID. The ID of the user, who added the attachment.
 *     \'ping_status\'   - Default is the value in default ping status option. Whether the attachment
 *                       can accept pings.
 *     \'post_parent\'   - Default is 0. Can use $parent parameter or set this for the post it belongs
 *                       to, if any.
 *     \'menu_order\'    - Default is 0. The order it is displayed.
 *     \'to_ping\'       - Whether to ping.
 *     \'pinged\'        - Default is empty string.
 *     \'post_password\' - Default is empty string. The password to access the attachment.
 *     \'guid\'          - Global Unique ID for referencing the attachment.
 *     \'post_content_filtered\' - Attachment post content filtered.
 *     \'post_excerpt\'  - Attachment excerpt.
 *
 * @since 2.0.0
