Receiving and Processing a multi dimensional array - php

Question

I have asked this question twice, with no satisfactory answer, that is, the problem I faced two questions ago still remains and none the wiser as how I am going to proceed with this.
This time I will provide all the code and what I receive, plus where the problem is occurring, I know what the issue is but since I'm relatively new to using AJAX it has me puzzled.
I have a form, which when you click the second to last field, duplicates itself, with the help of another user all the id's get changed to be unique.
<form role="form" class="batchinvoice form-horizontal" id="batchinvoice">
<div class="row">
<div class="form-group col-md-2">
<select class="form-control" name="sl_propid" >
<?php foreach($property as $row) :?>
<option value="<?php echo $row['id']; ?>">
<?php echo $row[ 'property_name'] . " " . $row[ 'property_address1']; ?>
</option>
<?php endforeach; ?>
</select>
</div>
<div class="form-group col-md-1">
<input type="text" name="sl_date" placeholder="Date" class="sl_date form-control" id="datepicker">
</div>
<div class="form-group col-md-2">
<input type="text" name="sl_ref" placeholder="Invoice Reference" class="form-control" id="sl_ref">
</div>
<div class="form-group col-md-2">
<select class="form-control" name="sl_nom_id" id="sl_nom_id">
<?php foreach($subitem_nominals as $row) :?>
<option value="<?php echo $row['subnom_id']; ?>">
<?php echo $row[ 'nom_subitem_name']; ?>
</option>
<?php endforeach; ?>
</select>
</div>
<div class="form-group col-md-2">
<input type="text" name="sl_desc" id="sl_desc" placeholder="Invoice Description" class="form-control">
</div>
<div class="form-group col-md-2">
<input type="text" name="sl_vat" placeholder="VAT Amount" class="vat form-control" id="vat">
</div>
<div class="form-group col-md-1">
<input type="text" name="sl_net" placeholder="Net" class="form-control" id="sl_net">
</div>
</form>
The JS for the form clone
<script>
var clone_iterator = 0;
$(function () {
var i = 0;
$.datepicker.setDefaults($.datepicker.regional['']);
$.datepicker.formatDate("yy-mm-dd");
$('#datepicker').datepicker();
$('#batchinvoice .vat').click(function () {
// alert("ok");
var id = "batchinvoice" + clone_iterator;
$('#batchinvoice').clone(true).attr("name", id).attr('id', id).appendTo(".panel-body"); // here I added this .attr('id',id)
// here we'll change the id's of all the elements who actualy have an attribute
$('#' + id + ' *[id]').each(function () {
$(this).attr('id', $(this).attr('id') + clone_iterator); //we set the attribute id
});
clone_iterator++;
});
$('#submit').click(function () {
var res = {};
console.log(res);
$('.batchinvoice').each(function (i) { //the class is a good use to do things like that you can repeat it more than once !
res[i] = new Array();
console.log(res);
res[i].propid = $(this).find('*[name=sl_propid]').val();
res[i].date = $(this).find('.sl_date formcontrol').val();
res[i].ref = $(this).find('*[name=sl_ref]').val();
res[i].id = $(this).find('*[name=sl_nom_id]').val();
res[i].desc = $(this).find('*[name=sl_desc]').val();
res[i].vat = $(this).find('*[name=sl_vat]').val();
res[i].net = $(this).find('*[name=sl_net]').val();
console.log(res);
alert(res[i].propid);
// i++;
//$.each('',function( index, value ){}
//(int)i is already incremented if you use class and not IDS
});
console.log(res);
$.ajax({
type: 'POST',
url: '<?php echo base_url(); ?>FinancialInput/addInvoiceToLedger',
data: res,
sucess: function (e) {
alert(e);
},
error: function (e) {
alert(e.toString());
}
});
});
});
</script>
This is the particular controller function in CodeIgniter, Note I have tried multiple things.
function addInvoiceToLedger(){
// $this->load->model('SalesLedgerModel');
// $propid = $this->input->post('propid');
// print_r($this->input->post());
// $date = $this->input->post('date');
// $ref = $this->input->post('ref');
// $nomid = $this->input->post('id');
// $desc = $this->input->post('desc');
// $vat = $this->input->post('vat');
// $net = $this->input->post('net');
$res = $this->input->post(NULL, TRUE);
//problem is probably here, it's
//for($x = 0; $x < count($res); $x++){
foreach($res as $row){
$this->SalesLedgerModel->addInvoiceToLedger($row.propid, $row.date, $row.ref, $row.nomid, $row.desc, $row.vat, $row.net);
}
//}
//redirect('home/financial_input/');
}
the Model Function
function addInvoiceToLedger($propid, $date, $ref, $nomid, $desc, $vat, $net){
$data = array('sl_prop_id' => $propid, 'sl_date' => $date,
'sl_ref' => $ref, 'sl_nominal_sub' => $nomid, 'sl_invoice_desc' => $desc, 'sl_vat' => $vat, 'sl_amount' => $net);
$this->db->insert_batch('salesledger', $data);
}
Which all have the relevant field data for each form inside them.
My question is how do I receive and handle the array? Every loop I've tried doesn't work, I've tried getting variables singularly(as you can see above commented out) but that doesn't make sense (or work) because in the $.ajax data it is set to res, but $this->input->post('res') doesn't return anything nor does $this->input->post(NULL, TRUE)
Majorly stuck, I feel this should be a simple thing, but I clearly don't understand it.
Edit, still same problem can't find an answer anywhere D:, tried many things.
Still the same problem "res" is sent as post, but I can't retrieve it in the controller with $this->input->post()...anyone?

I only wanted to submit a comment but apparently I need 50 rep for that so I'll take my chances with an answer.
In your $.ajax block what if you change the data section to this:
$.ajax({
type: 'POST',
url: '<?php echo base_url(); ?>FinancialInput/addInvoiceToLedger',
data: { res : res },
sucess: function (e) {
alert(e);
},
error: function (e) {
alert(e.toString());
}
});
