registerWithCredentials（）存储过程

Question

我在MyQL中为我的Wordpress数据库创建了一个存储过程。这一程序的目的是为了注册一个新用户导入到WordPress中使用数据库凭据（user_login，user_pass，user_nicename，user_email和displayname） 这个程序的SQL语法是好的，但是当我打电话的过程我不能得到任何东西响应，它会告诉用户是否将新用户添加到数据库中。我不知道问题是什么，因为当我调用过程后检入数据库时​​，我看不到有任何更改。

我认为您需要在代码的末尾进行选择，以便您可以从存储过程输出内容。如果我像你一样，我会输出新注册用户的数据。这里是程序，希望它有帮助：
