I need help with the part below and please add comments in the code to help me understand better what I am doing wrong in my own code.

I have already created my database and the connection and some of the code but am stuck on these parts.



"Home" and "Create Account" pages

• The
  index.phpfile will ask the user to log in to the system with a login form
  
  
  
  • If they're already logged in, the home page will
    
    NOT
    
    show the login form. It will show a "welcome to our store" type of message instead even if they click on the "home" button in the navigation.
  
  
  
  


• The
  create-account.php
  page has them fill out a form for creating an account.
  
  
  
  • Use real-time JavaScript validation (and regex) to:
    
    
    
    • Verify that the password and "verify password" match as they are typing.
    
    
    • Verify that the password contains at least one number and is at least 8 characters long
    
    
    • Be sure to display user feedback messages on the screen as they type, e.g.:
      
      
      
      • Password must contain a number
      
      
      • Password must be 8 characters long
      
      
      • Password and "Verify Password" do not match.
      
      
      
      
    
    
    • Disable the "create account" button until the above conditions are met
