Saving array to database cakephp - arrays

Question

I have a form that has multiple entries to the same table, the problem I'm having is that it only sends the last entry to the database and doesn't send the rest. I have used the debug and it only prints out the last field in the form.
With each iteration of field its meant to input into the fields_invoices table a invoice_id, field_id, entered_value
Here is my form
<?php echo $this->Form->create('FieldsInvoice'); ?>
<?php foreach ($fields as $field): ?>
<?php echo $this->Form->hidden('FieldsInvoice.id'); ?>
<?php echo $this->Form->hidden('FieldsInvoice.field_id', array('default' =>$field['Field']['id'])); ?>
<?php echo $this->Form->input('FieldsInvoice.invoice_id', array('default' =>$invoice_id, 'type'=>'hidden')); ?>
<?php echo $this->Form->Input('FieldsInvoice.entered_value', array('label'=>$field['Field']['name'], 'default' =>$field['Field']['default_value'])); ?>
<?php endforeach ;?>
<?php echo $this->Form->End('Submit');?>
Here is the related controller
public function create($id)
{
$this->set('title_for_layout', 'Create Invoice');
$this->set('stylesheet_used', 'homestyle');
$this->set('image_used', 'eBOXLogoHome.png');
$this->layout='home_layout';
if (!is_numeric($id)) throw new BadMethodCallException('I need an ID');
$this->Invoice->id = $id;
if (!$this->Invoice->exists()) throw new NotFoundException('Invalid ID');
$this->set('invoice_id',$id);
$names = $this->Invoice->find('list',array(
'fields'=>array('template_id'),
'conditions'=>array('id'=>$id)));
$fields = $this->Field->find('all', array(
'conditions'=>array(
'template_id'=>$names)));
$this->set(compact('fields'));
$this->set(compact('invoice_id'));
$this->set('name',$names);
$this->Invoice->create();
if(empty($this->data)){
$this->data= $this->Field->read($id);
}
else{
if($this->request->is('post'))
{
//die(debug($this->data));
$this->Invoice->create();
if($this->FieldsInvoice->save($this->request->data, array('deep'=>true)));
{
$this->Session->setFlash('The field has been updated');
$this->redirect(array('controller'=>'invoices', 'action'=>'index'));
}
//else{
$this->Session->setFlash('Could not be saved');
//}
}
}
}

To post multiple fields, use:
foreach ($fields as $idx => $field):
echo $this->Form->hidden('FieldsInvoice.'.$idx.'.id');
echo $this->Form->hidden('FieldsInvoice.'.$idx.'.field_id', ...);
...
and then use $this->FieldsInvoice->saveMany() (instead of ->save()) to save multiple records.
