在WordPress网站中进行审核后，如何触发功能？

Question

我想为插件编写一些代码，该插件在用户进行检查后（wp_comments表已更新）会触发一个告诉它执行某项操作的函数。我怎么知道是否进行了新的评论，因为评论是使用comment_type='review'作为评论保存到数据库的？

Answer 1

创建新评论时，可以使用comment_post操作挂钩执行操作：

/**

 * Performs an action after a review has been created.

 *

 * @param   int         $comment_ID

 * @param   int|string  $comment_approved (1 if approved, 0 if not, 'spam' if spam)

 * @param   array       $commentdata

 */

function show_message_function( $comment_ID, $comment_approved, $commentdata ) {

    if ( 'review' == $commentdata['comment_type'] ) {

        // A new review has been created, do something here.

    }

}

add_action( 'comment_post', 'show_message_function', 10, 3 );

该$commentdata阵列会是这个样子：

Array

(

    [comment_post_ID] => 16

    [comment_author] => John Doe

    [comment_author_email] => [e-mail]

    [comment_author_url] => 

    [comment_content] => My awesome review!

    [comment_type] => review

    [comment_parent] => 0

    [user_ID] => 1

    [user_id] => 1

    [comment_author_IP] => ::1

    [comment_agent] => Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:66.0) Gecko/20100101 Firefox/66.0

    [comment_date] => 2019-04-13 14:11:45

    [comment_date_gmt] => 2019-04-13 14:11:45

    [filtered] => 1

    [comment_approved] => 1

)
