Using HTML 'hidden' Input Fields


How To Use "hidden" Input Fields?



A "hidden" input field is defined as <input type="hidden" .../>. "hidden" input fields can be used to create invisible fields with predefined input values hidden in the form. There are other attributes you need to use for a "hidden" input field:

  • name="fieldName" - Specifies the name of this field.
  • value="hiddenValue" - Specifies the hidden value for this field.

Here is a tutorial example with 2 hidden input fields:

<?xml version="1.0" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
  <title>Hidden Input Fields</title>
  <h4>Online Survey</h4>
  <form action="http://localhost/submit" method="get">
  <p style="background-color: #eeeeee; padding: 8px;">
   Your name: <input type="text" name="name"
    value="Joe Miller"/><br/>
   Your email: <input type="text" name="email"
    value="" size="32" maxlength="60"/><br/>
   <input type="hidden" name="site" value="FYIcenter"/>
   <input type="hidden" name="keys" value="FAQ,XHTML"/>
   <input type="submit" value="Submit"/> 

If you save the above document as hidden_input.html, and view it with Internet Explorer, you will not see any signs of the 2 hidden input fields. But you click the submit button, you will get:
