Firstly we faced the problem during creating the user friendly interface and by using html,css,bootstrap,bootstrap alerts,javascript to create an interactive website.
In the backend part we tried a lot more to solve the problem of getting back to logged in page after hitting the back button after logout and finally we solved it by destroying the session.
We also faced the many problem during the session management of website like where to start session and destroy and also ffaced the problem during accessing the variable stored in session.
We saw some of our website features get accessed without login by searching directly the URL of that page and this problem also get solved by our team in a very efficient manner by using session.
During the connetction with database we got many warnings and errors like sometimes we got call-stack error because we are starting the session more than once.
We also got the error in running and writing query and fetching the the results required to use in our code.
We faced a lot of problem in deploying our website , we deployed our website but we hadn't created database in cloud that's
why our website showing a lot of errors and warnings in connection, we solved it by creating a database and now we are still facing problem our website working good in localhost server but still in problem with online server we are solving that.
