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 PHP
