Hidden Fields

In the previous example, we needed the bearcat ID to open the file. We passed it through the URL.

<br><a href =

\"http://oz.uc.edu/cgi-bin/cgiwrap/jonesbr/whatIsaid.pl?bearcatID=$bearcatID\">Now see what I said!</a>

This is perfectly legal, but we are passing it through GET. GET has its limitations. What are they?

There's another way to pass the bearcat ID between forms. We can dynamically append it by using cookies.
But there is still another way: hidden fields.

Hidden fields are just like any other FORM element, but they are not displayed on the HTML page.
You can view them via View-Source on the browser.
This is an easy way to pass data between forms, and to your Perl script.
Just use this syntax:

<input type = "hidden" name = "bearcatID" value = "jonesbr">
