Help me see what's going on. Thanks
What I saw yesterday was that when submitting information to the ‘Student Relations System’, the page did not jump and the database did not receive the information. I don’t know how to solve the problem, because the information in the video can only be seen in the database. I really couldn’t figure it out, so I gave up.
What we are looking at today is the ‘Message Board System’, which is also during the ‘Submit Documents’ step. The page did not jump, and no data changes were found in the database. I checked the code several times and couldn't find any errors.
