On the 2nd point : you can name your input like you want, even without the user_ but :

  • often the input name is given by the backend developpers (because it's their scripts who will run most of the operation), frontend developper only use it
  • often the name start with an user_ to remind backend developpers to parse it through a security check before using it (because input field are an entry point for XSS attacks)

What i understood from that - Can you make the ID of an element whatever you like or do they have specific names. You can make an ID anything you want usually it has a meaning to it, for example if I had a paragraph which displayed data for video I would call it something like videoData. And for the naming of a input do you mean like <input name="name?"> - if so then it can be anything you want aswell with the ID.

Thank you Rhys kearns
