Example OneExample Two

A simple example of data input

Example One:

This is a snippet from a form class showing the insert method. This is called from a file that is in turn called from a JavaScript file using the jQuery interpretation of AJAX.

Once the form has been validated via javaScript and AJAX the relevant data is pushed into an array that is then parsed by the database class. The database connection is dealt with at the beginning and end of each method.

Example Two:

This shows how the received data is inserted into the database from the parsed array and how each string is cleaned to prevent SQL injection.
