Form validation

This was an assignment for the PHP portion of my coding bootcamp. It is a fictional form that requires validation upon submission. There are two types of validation in this project: single page validation, and validation over two pages.

Stack used: PHP - HTML

The brief

These were the detailed instructions for the assignment:

Two pages:

• Create a multi-page form handling PHP script that parses an HTML form with the following user data and constraints. The validator should consist of two files: an HTML file with the form and a PHP file with the validation code.
  • Email (valid email address)
  • Username (6-10 characters; alphanumeric only)
  • Password (at least one lowercase letter, one uppercase letter, and one number)
  • Date of birth (after 1900, and before 2020)
  • Gender (either “male”, “female”, or “other”)
  • Address (multiple lines)
• Your script should display an appropriate error message if the user enters bad input. It should not re-render the form. You may use a combination of HTML form constraints and PHP form validation.

Single page:

• Do the same as above, but with a single page form handling script.
• If the user enters bad input, your script should display an error message and repopulate the form so that the user can change their entered data.
• Note that the Password field should be exempt from repopulation. It should always be blank on every form render.
