Week 8

This week we learned on PHP and form processing. PHP is good at handling data submitted to the server in HTML forms. Form is used to accept user input in a systematic and structured manner. There are two main attributes in a form which are method and action.

1.   $_POST
Form processing with $_POST- welcome.html

welcome.html with POST method

output

Displaying Submitted Values- welcome.php

welcome.php with POST method

output

2.   $_GET
Form processing with $_GET- welcome.html

welcome.html with method GET

output

Displaying Submitted Values- welcome.php

welcome.php with GET method

output

 3.   $_REQUEST variable: it contains contents both $_GET, $_POST and $_COOKIE. It can be used to get the result from form data sent with both the GET and POST methods. 

For the lab session

We have done some discussion on past year question regarding to processing CGPA.
