Hidden fields are special fields in a form that are not shown on the Web page. But when the form is submitted, values specified in the hidden fields are also submitted to the Web server. A hidden field can be specified with the <INPUT TYPE=HIDDEN ...> tag. The PHP script below shows you a good example:

<?php
  print("<html><form action=processing_forms.php method=post>");
  print("<input type=hidden name=module value=FAQ>\n");
  print("<table><tr><td colspan=2>Please enter and submit your"
    ." comments about FYICenter.com:</td></tr>");
  print("<tr><td>Your Name:</td>"
    ."<td><input type=text name=name></td></tr>\n");
  print("<tr><td>Comments:</td>"
    ."<td><input type=text name=comment size=40>"
    ."</td></tr>\n");
  print("<tr><td colspan=2>"
    .'<input type=submit name=submit value="Submit">'
    ."<td></tr></table>\n");
  print("</form></html>\n");
?>

If you submit this form, you will get something like this:

Number of values: 4
  module = FAQ
  name = Peter
  comment = Thanks for the good tips.
  submit = Submit
