nestedSortable on codeigniter - php

Question

I do sorting function with codeigniter for pages with "nestedSortable".. When i click submit button it doesnt find " {sortable: cSortable}"
my code example:
in views
$(document).ready(function() {
$.post('<?php echo site_url('admin/pages/order_ajax'); ?>', {}, function(data) {
$('#orderResult').html(data);
});
$('#save').click(function() {
oSortable = $('.sortable').nestedSortable('toArray');
$.post('<?php echo site_url('admin/pages/order_ajax'); ?>', {sortable: cSortable}, function(data) {
$('#orderResult').html(data);
});
});
});
in model file
public function save_order($pages) {
if (count($pages)) {
foreach ($pages as $order => $page) {
dump($page);
if ($page['item_id'] != '') {
$data = array('parent_id' => (int) $page['parent_id'], 'order' => $order);
$this->db->set($data)->where($this->_primary_key, $page['item_id'])->update($this->_table_name);
echo '<pre>' . $this->db->last_query() . '</pre>';
}
}
}
}
in the controller file
public function order_ajax() {
// save order from ajax call
if (isset($_POST['sortable'])) {
$this->page_m->save_order($_POST['sortable']);
}
//fetch all pages
$this->data['pages'] = $this->page_m->get_nested();
//fetch view
$this->load->view('admin/pages/order_ajax', $this->data);
}
I see this error http://i57.tinypic.com/2uj6wpd.jpg
another error:
<?php
echo get_ol($pages);
function get_ol($array, $child = FALSE) {
$str = '';
if (count($array)) {
$str .= $child == FALSE ? '<ol class="sortable">' : '<ol>';
foreach ($array as $item) {
$str .= '<li id="list_' . $item['id'] . '">';
$str .= '<div>' . $item['title'] . '</div>';
//do we have childrens ?
if (isset($item['children']) && count($item['children'])) {
$str .= get_ol($item['children'], TRUE);
}
$str .= '</li>' . PHP_EOL;
}
$str .= '</ol>' . PHP_EOL;
}
return $str;
}
?>
so i dont get it shows me on line 10 and 11 that could't find name and title
"TypeError: parentItem is null
pid = parentItem[2];"

Answer 1

Looks like a type, wrong variable name. Should cSortable actually be oSortable?
