Homework 12: Authentication

Watch these videos:

• Authentication (YouTube Links to an external site.)
• Authentication in PHP (YouTube Links to an external site.)
  
  • the code from the video Links to an external site.

We ended class by adding two new tables to the database (Users and Quizzes) and updated the code for creating QuizItems and Submissions to include quizID and sumitterId. After class, I updated the other parts of the code to include that new information. Here's the final version Links to an external site..

In the class code, update the code that creates the Users table so it includes a password field. Add a "Add user" form to the api-client.html page, and code to handle adding a user in api.php and db.php; the code in api.php is responsible for creating the password hash. In api.php, add a function called authenticate(username, password) that returns true if the user is authenticated, or sets the response header error code to 401 (Unauthorized) and dies with an error saying the username or password were bad otherwise (see the code from the video for how to do that).  Finally, make it so that authentication (i.e., a valid username and password) are required in order to add or update a Quiz or QuizItem in api-client.html.

Remember, to get credit for the homework, you don't have to have solutions that are 100% complete and working; I want to see that you made an effort to get them working so you can ask informed questions in class and so that when we go over and extend the homework in class, you have some working context for what we're doing.

Commit your two PHP files in a folder homework/hw12/ in your CSC302 git repo and push to GitHub. Submit a link to your the hw12 folder on GitHub to this Canvas assignment.
