All geek questions in one place

The function is not called for each session value.

I am developing a game portal in which a professor should be able to add any questions to it. I created question types (multiple choice or descriptive) in form.php and I included it in my main file. First of all, in the loop, I call the main unit (a simple html window) in which I must add a question. then I give the opportunity to choose the type of question to add a question. When choosing the type of question, the page loads and submits the form, and I get this value and save the dynamically created session variable. Everything works fine, but the main problem is that when I select the type of question, it selects it for this particular window, but all other questions disappear. Maybe its rewrite values ​​in the session variable. Please guide me.
