Contact Form<\/b> is a must-have component for every web application. It’s a simple and quick way to communicate with the website owner. Through the Contact Us form the website’s visitor can submit their questions, feedback, and suggestions to the site administrator. In the same way, contact us form is very useful for the site owner to get the service requests or customer queries directly from the website.<\/p>\n
In most cases, the submitted contact request is sent to the site admin via email. So, the site admin of the respective organization can get the request instantly and send a quick response to the sender. Also, the response can send automatically to the request sender from the script. In this tutorial, we will show you how to create a simple contact form in CodeIgniter<\/b> framework and send email after the form submission. The example code helps you to build CodeIgniter contact us form<\/b> with validation and email sending<\/a> functionality.<\/p>\n The Contact controller handles the contact form submission process, it has 3 functions, index()<\/b> –<\/p>\n sendEmail()<\/b> –<\/p>\nController (Contact.php)<\/h2>\n
__construct()<\/code>, index()<\/code>, and sendEmail()<\/code>.
\n__construct()<\/b> – Loads the Form Validation library.<\/p>\n\n
