This is the file code of the file. The problem is when the teacher is going to register a student, he has to go through this screen to select the course when he / she registers. The course is saved in the database as a secretariat. the last course, but it is not to happen, he has to click on a course and the course he clicked is to be saved together with the student. Any more experienced php programmer could help me ?? Thanks in advance for your help.
