[phpesp-dev] Previous Button Added

[Stephen L. Jr. <sla...@uc...>]

Hey all, I have been asked by a user to incorporate a previous button 
into phpesp for multi-page surveys. So, here it is. Can you guys take a 
peek at this, or maybe try it out, and make sure it is done properly. 
Maybe there is a better way?

* Displays "Next" only when first page is viewd
* Displays "Previous" and "Next" when middle pages are viewed
* Displays "Previous" and "Submit" when last page is viewed

$ diff public/handler.php ../../phpESP_cvs/public/handler.php

<       // Previous button start
<       if(!empty($HTTP_POST_VARS['previous'])) {
<               $msg = response_check_required($sid,$HTTP_POST_VARS['sec']);
<               if(empty($msg)) {
<                       $HTTP_POST_VARS['rid'] = 
response_insert($sid,$HTTP_POST_VARS['sec'],$HTTP_POST_VARS['rid']);
<                       $HTTP_POST_VARS['sec']--;
<               }
<       }
