Cannot pass textarea input to a PHP variable - php

Question

To begin, I'm working with 3 languages. HTML, Javascript and PHP. I'm unable to pass user inputted textarea text to a PHP variable which would be used as a message in an email that would be sent out. What I believe to be the problem is that my textarea is actually in a modal window and for some reason I think that is what is screwing things up.
Here is my HTML Code:
<form name="rejectForm" action="">
<div class="rejectModal" title="rejectModal" id="rejectModal" style="display: none; padding:15px ">
<b> Text in the modal window</b>
<center>
<textarea id="rejectArea" name="rejectArea" value="{$rejectAreaNote}" rows="6" cols="43"/> </textarea>
</center>
<br/>
<center>
<input type="button" value="Reject" class="btn success id="submitReject"" id="btnRejectDocumentModal" name="Reject" />
<input class="btn" type="reset" value="Cancel" id="btnCancelSaveModal" />
</center><br/><br/>
</div>
</form>
</div>
JS Code:
$(function() {
$(".submitReject").click(function() {
// validate and process form here
$('.error').hide();
var rejectAreaNote = $("textarea#rejectArea").val();
var noteLength = rejectAreaNote.length;
if (rejectAreaNote == "" || noteLength < 5) {
$("label#rejectArea_error").show();
$("textarea#rejectArea").focus();
return false;
}
var dataString = rejectAreaNote;
alert (dataString);return false;
$.ajax({
type: "POST",
url: "gs_ViewDocument.php",
data: dataString,
success: function() {
$('#reject_form').html("<div id='message'></div>");
$('#message').html("Reject Form Submitted!");
}
});
return false;
});
});
What creates the Modal (JS):
$('.rejectModal').css("background", "lightblue");
$('#btnRejectDocument').bind(isTouchScreen ? "touchstart" : "click", function(){
if (!gsSelection.unselectElem()) return false;
$('.rejectModal').dialog({
modal:true,
resizable:false,
width: 400,
}).removeClass("ui-widget-content");
$(".ui-dialog-titlebar").hide();
return;
});
$('#btnRejectDocumentModal').bind(isTouchScreen ? "touchstart" : "click", function(){
$(this).parents('div.rejectModal').dialog('close');
});
$('#btnCancelSaveModal').bind(isTouchScreen ? "touchstart" : "click", function(){
$(this).parents('div.rejectModal').dialog('close');
});
PHP Code:
if(isset($_POST['Reject'])&&$_POST['Reject']=='Reject')
{
$isReject = true;
RejectAction($DocumentID, $ClientName, $ClientEmail);
$smartyvalues["isReject"] = $isReject;
$smartyvalues["RejectMsg"] = "The document invitation was successfully rejected!";
}
Any help is greatly appreciated.

Answer 1

Try the below is should fix it :
<textarea id="rejectArea" name="rejectArea" rows="6" cols="43"> {$rejectAreaNote}</textarea>
you were closing your textarea tag twice /> and then </textarea>

Answer 2

<input type="button" value="Reject" class="btn success id="submitReject"" id="btnRejectDocumentModal" name="Reject" />
The closing quotes here are wrong (Two quotes after submitReject).
