There were several modifications in different files. The database has been modified and enhanced for the new features of the project, such as upload. Please update your repositories based on the last changes made.
There are also several tasks that need to be done:

1. The table should not allow duplicate passwords, and the correct message should be shown to the user if there is already someone with the same username or password exists.
2. An acceptable user interface should be created to sign up and sign in.
3. The things that the user inserts in the field should be processed before being inserted into the database.
4. we got a problem when the user changes two fields at the same time, whether it is in sign-up, sign-in or search.
5. The user-id should be fixed. It should get the user_id when the user signs in into the website.
6. The results gotten from the query in the table in tableIndex.html are not shown nicely into the table.
