I have a web page set up for doctors to request vacation. All was
working well until they upgrade their home PCs to IE7, at which time
the variables lose their values when they click submit. We've allowed
cookies from this site and allowed JS to run in an attempt to fix the
issue, but no luck.
I use a javascript calendar and additional javascript to make sure the
end date > start date.
The user can still use the calendar tool to select dates and the js
still correctly ensures the end date and num of days requested fields
are populated correctly, so I am looking at my PHP code first.
Is there some error in my handling of session variables?
PHP code:
<?php
/**
* request.php
*
* Sends an email containing a vacation request and posts to database.
*
*/
session_start();
//Let's see if they want to go to another page first
if (strlen($btn) > 0) {
//save this pages info in case they come back
$rqst['Priority'] = $Priority;
$rqst['txtStartDate'] = $txtStartDate;
$rqst['txtEndDate'] = $txtEndDate;
$rqst['body'] = $body;
$rqst['txtNumReq'] = $txtNumReq;
