Web Forms and Data Collection Quiz

• Forms are a group of one or more fields on a web page that can be used to collect user input.
• Forms are a flexible mechanism for collecting user input because there are suitable form inputs available for entering many different types of data.
• Forms are also a relatively secure way of sharing data with the server, as they allow us to send data in POST requests with cross-site request forgery protection.
• Developers need to write HTML for the form, validate and properly sanitize entered data on the server (and possibly also in the browser), repost the form with error messages to inform users of any invalid fields, handle the data when it has successfully been submitted, and finally respond to the user in some way to indicate success.

Test your knowledge of creating and handling web forms, including form inputs, data validation, security measures, and server-side handling. Learn about the different types of data collection mechanisms available for web development.
