Do you mean validation on the server side?

If so, a typical form is in a script named like edit.cgi , like :

...
print ui_form_start("save.cgi");
print "Your name: ",ui_textbox("name", "", 40);
print ui_submit("Save");
print ui_form_end();
...

and validation is done in save.cgi like :

...
ReadParse();
if ($in{'name'} eq '') {
  error("You didn't enter a name");
  }
...
