$this->request->data EMPTY - When I have disabled Fields CakePHP 2 - forms

Question

I have a form which has some disabled fields, when the form is submitted both $this->request->data and $_POST is empty, removing the disabled fields and it is fine again. I would have though it would still pass though the non-disabled fields. I've even tried to remove the disabled field attribute when the submit button is pushed but this still returns an empty array.
Is there something cake related that might be causing this?
Thanks
// SNIPPET FROM THE VIEW CODE:
$this->Form->create('Card', array('class' => 'GeneralValidate'));
$this->Form->input('Card.property_id', array('type'=>'select', 'empty'=>true , 'class' => 'required adminOnlyField', 'div' => array('class' => 'required')));
$this->Form->input('Card.building_id', array('type'=>'select', 'empty'=>true, 'id' => 'BuildingSelector', 'class' => 'adminOnlyField', 'label' => 'Building (If Applicable)'));
$this->Form->input('Prospect.waiting_list_details', array('value' => $prospect['Prospect']['waiting_list_details']));
$this->Form->input('SaleDetail.property_sold', array('class' => 'checkbox', 'checked' => $ps_checked));
$this->Form->input('SaleDetail.date_conditions_met', array('type'=>'text', 'class' => 'text date_picker adminOnlyField', 'value' => $this->Date->format($saledetail['SaleDetail']['date_conditions_met'])));
$this->Form->button('Save & Continue', array('type'=>'submit', 'label' => 'Save', 'name' => 'quicksave' , 'class' => 'submit long clear_ready_only'));
// JS FROM THE VIEW
$(function () {
var $adminOnly = $('.adminOnlyField');
$adminOnly.prop('disabled',true).prop('readonly',true);
$adminOnly.attr("onclick","return false");
$adminOnly.attr("onkeydown","return false");
$adminOnly.removeClass('required');
$adminOnly.removeClass('date_picker');
$('.clear_ready_only').click(function(e)
{
e.preventDefault();
$adminOnly.prop('disabled',false).prop('readonly',false);
$adminOnly.attr("onclick","return true");
$adminOnly.attr("onkeydown","return true");
$('#CardModifysaleForm').submit();
});
});

Answer 1

That's the way HTML works, disabled don't get posted. CakePHP can't change what is sent from the browser. If you still want the value you can set it as a hidden element.
Update
Some problems I see:
Missing Form::end() in view (always a good idea to insert it).
You never said your form was submitted from JS, first test with a simple form POST then JS.
Your JS code is set to submit a form by ID CardModifysaleForm. There's no such ID in your supplied view code and you're not setting your form to that ID from the snippet you supply.

Answer 2

I ended up removing the disabled option from this, leaving the ready only and added some addition CSS stylings so it looked disabled to the user. This is not the exact answer to the question but works as a different approach.
