Send This array to php and get results in div (FCBKcomplete) - php

Question

I'm using an autosuggest plugin that allows me to select multiple items from a dropdown menu (demo here). I want a query to be sent to a php file (I will be preoccupied with the query itself later) and get a result back without leaving the page.
The php file is pretty much empty right now:
<?php print_r($_REQUEST); ?>
But I know I made a mistake with my jquery somewhere since the search box is not displaying properly anymore.
Here's the code I built up, I'm not sure what to put in the "data" field.
<script type="text/javascript">
$(document).ready(function(){
$("#select3").fcbkcomplete({
json_url: "data.txt",
addontab: true,
maxitems: 10,
input_min_size: 0,
height: 10,
cache: true,
newel: false,
filter_selected: true,
maxitimes: 5,
// I did this
onselect:"get_venue",
});
// I also did this
function get_venue() {
$("#select3 option:selected").each(function() {
$.ajax({
type: 'POST',
url: 'post.php',
dataType: 'json',
data: {
WHAT DATA GOES HERE?
},
success : function(data){
$('#phpmessage').removeClass().addClass((data.error === true) ? 'error' : 'success')
.text(data.msg).show(500);
if (data.error === true)
},
error : function(XMLHttpRequest, textStatus, errorThrown) {
$('#waiting').hide(500);
$('#phpmessage').removeClass().addClass('error')
.text('There was an error.').show(500);
}
});
});
}
});
</script>
Sorry for such a long post everybody :)!! Thanks :))
Error I'm getting:
Is not a function: return func.call(func, _object);
function funCall(func, item) {
var _object = {};
for (i = 0; i < item.get(0).attributes.length; i++) {
if (item.get(0).attributes[i].nodeValue != null) {
_object["_" + item.get(0).attributes[i].nodeName] = item.get(0).attributes[i].nodeValue;
}
}
return func.call(func, _object);
}
function checkFocusOn() {
if (focuson == null || focuson.length == 0) {
return false;
}
return true;
}

You want to loop over each of the items in the search box, these have a class of .bit-box. Create an array of these search terms then send them in as data into the ajax request.
function get_venue() {
var data = [];
$('.bit-box').each(function() {
data.push( $(this).text );
});
$.ajax({
type: 'POST',
url: 'post.php',
dataType: 'json',
data: {
'choices[]': data
},
success : function(data){
$('#phpmessage')
.removeClass()
.addClass((data.error === true) ? 'error' : 'success')
.text(data.msg).show(500);
if (data.error === true){
}
},
error : function(XMLHttpRequest, textStatus, errorThrown) {
$('#waiting').hide(500);
$('#phpmessage').removeClass().addClass('error')
.text('There was an error.').show(500);
}
});
}
