replyTeacher, you finally replied to the lesson on preventing login and repeated login. I checked it for two days and compared it. Everything is wrong. TP5 does not show any error prompts. I don’t know what is wrong. I checked it several times and it is wrong.
Donor: Please also post the source code, or indicate which course you are reading, so that I can know how to help you?
Moreover, there is no prompt when reporting errors in TP5. I don’t know where the error is at all.
