A hidden field is a region of the form that is not displayed to the user. You can use these fields to store data and transfer it from one form to another. For instance, suppose a user completes an order form then presses a Send button. You then present the user with a confirmation notice. If you click OK on the confirmation notice, you want to automatically send the data to the server. In this case, the confirmation window may contain a hidden field to store the order form data.
This name does not appear on the form; it's stored in the HTML file. The cgi-bin script uses this name to identify the information collected from that field.
This step is optional. The text is not displayed when the document is viewed using an HTML browser. It's displayed only while you're editing in Cosmo Create.
A text field appears on the page. It represents the hidden field.
