Page with multiple forms not redirecting to page

[oitnsu]

Good afternoon:

I am fairly new to php so I'm not sure how to word this question. I am building a clearance form for our hr department which involves around 13 departments. I have written most of the code; however, I am having problems with the approval page. I have multiple forms each named differently with different submit buttons. Only one form per department is displayed based on the approver's department code. After the form is validated and submitted, the user should be redirected to thankyou.html page. This does not happens and the form disappears but the page remains. Any advice. The code for each form is basically the same. The code for one of the forms is below:

if($deptid==2)
{
if($submithroffice == "yes")
{
//VALIDATION-------------------------------------------------------------

if(!isset($leavereporting))
{
$formfailure = 4;
}
elseif((!is_numeric($sick) || !is_numeric($annual)) && $leavereporting == 1)
{
$formfailure = 5;
$Leaveerror = "You must enter a value for leave balance.";
}

if($leavereporting == 1 || $leavereporting == 0 && !$modify)
{
$updateqry2 = "UPDATE ApprovedItems SET annual = '$annual', sick = '$sick', bank = '$bank' WHERE formID =".$formid;
$updatedo2 = odbc_do($dbconnect, $updateqry2);
$sendemail = "leavetopayroll";
include("sendemail.php");

//redirect to thank you page
$url = "http://apps2.nsu.edu/hrclearance/thankyou.html";
header("Location :".$url);
exit();
}

if(empty($hrrejcmt) && $leavereporting == 2)
{
$formfailure = 4;
}
if($leavereporting == "2")
{
$sendemail = "deptcorrectleave";
$updateqryerr = "UPDATE ApprovedItems SET hr_rejectcmt = '$hrrejcmt' WHERE formID = ".$formid;
$updatedoerr = odbc_do($dbconnect, $updateqryerr);
include("emailcorrection.php");
}

if($formfailure == 4)
{
print '<div style="text-align:center;font-size:15px;color:#CC0000;font-weight:bolder">You have left a field blank or you have submitted a reject without a rejection comment.</br>'.$errorLeave.'</div>';
}
elseif($formfailure == 5)
{
print '<div style="text-align:center;font-size:15px;color:#CC0000;font-weight:bolder">You have left a field blank or you have submitted a reject without a rejection comment.</br>'.$Leaveerror.'</div>';
}
}
}

Not sure this will work for you, but try throwing ob_start(); just after your files opening <?php tag. Would look like this:

<?php
ob_start();
