Server-Side (HOW-TO) Page

[virtualhost 0]

I think W3Schools should add some server-side languages and show some examples onto the How-To page. Like for example, PHP 7 and Node.JS..

Showing examples of shopping cart, sign-up/login forms, contact form, etc.. should be very useful.

All of your examples are just differing types of what is already there. Here are some of technologies you can use to make the most very basic ones. These aren't particularly tricky to do, and it's good for people to learn how to put the pieces together. If you get stuck, we're always here.

An example for PHP7

Shopping Cart

• Use $_GET parameters on links for each items to a process page of some sort to assign to a Database. (AJAX preferable)
• https://www.w3schools.com/php7/php7_superglobals.asp
• https://www.w3schools.com/php7/php7_mysql_insert.asp

Sign Up/login forms

• This is Form Handling, and SQL retrieval/insertion (usually prepared for security)
• https://www.w3schools.com/php7/php7_forms.asp
• https://www.w3schools.com/php7/php7_mysql_select.asp
• https://www.w3schools.com/php7/php7_mysql_prepared_statements.asp

Contact Form

• Only Form Handling and Validation

 

To make any of these processes smoother, use AJAX.
