In this article you’ll construct and validate a simple form using HTML and PHP. The form is created using HTML and validation and processing of the form’s contents is done with PHP. The goal is to teach you some basic HTML form elements and how their data is accessible to you in your PHP scripts.
The form you’ll create contains a number of inputs: text fields, radio buttons, a multiple-option select list, a checkbox, and a submit button. These inputs will be validated to ensure, for example, that the user has entered their name. Any errors or omissions will be highlighted with a message alongside the relevant field.

Text Fields
The name, address, and email fields are text input elements and can be coded like this:
