Advantage of Ajax in feedback form here.

The main advantage is we can validate the user inputs and display the error message without reloading the page. After checking the error message it became easy for the user to take corrective action. There are three files used to develop the contact us script.

contactus.php

This file displays the basic form in html. On submit of this form the Ajax function ajaxFunction() is triggered.

contactus-ajax-code.js

This is an external JavaScript code attached to contactus.php page. The ajax code is kept here

contactusck-ajax.php

This file collects all the user input data and validates them. If data validation is clear then it gives a thanks message. If the validation fails then corresponding error message is returned to conactus.php page.

In addition to above three files there is one style sheet file ( style.css ) attached to contactus.php page.
In the contactusck-ajax.php page update your email address before using the script.

mail("user@example.com",$sub,$body_dtl,$headers); // Posting mail
