If the message sending in the red box is added, the public number can be used to send messages to the user, but the ajax return value cannot be used to output the message sending part in the red box, and the return value can be output again, after the message sending code in the red box is imitated, the message sending function becomes invalid again. I just want to implement it. the user places an order to receive the notification...

Remove the message sending part from the red box, and the return value can be output again. The message sending code in the red box is imitated, and the message sending function becomes invalid again.
I just want to implement the function of notifying the person who receives the Order by the user. what should I do ????
