Awe, I don't know how long I've been at this now. If someone can tell me what I'm doing wrong I'll bake some cookies.
Anyway, I have a database
Code: --
-- Table structure for table `content_menus`
--
DROP TABLE IF EXISTS `content_menus`;
CREATE TABLE IF NOT EXISTS `content_menus` (
`menu_id` int(11) NOT NULL AUTO_INCREMENT,
`content_id` int(11) NOT NULL,
`content_menu_title` varchar(255) NOT NULL,
`menu_position` bigint(20) NOT NULL,
`parent` int(11) NOT NULL,
PRIMARY KEY (`menu_id`),
UNIQUE KEY `content_menu_id` (`menu_id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=51 ;
--
-- Dumping data for table `content_menus`
--
INSERT INTO `content_menus` (`menu_id`, `content_id`, `content_menu_title`, `menu_position`, `parent`) VALUES
(3, 1, 'Home', 0, 1),
(45, 2, 'Services', 1, 1),
(5, 3, 'Clients', 2, 1),
(6, 4, 'Portfolio', 3, 1),
(7, 5, 'Blog', 4, 1),
(8, 14, 'Web Design', 1, 2),
(9, 15, 'Web Design Scotland', 0, 8),
(2, 0, 'Footer Menu', 2, 0),
(12, 6, 'Contact', 5, 1),
(31, 38, 'Web Design', 0, 4),
(1, 0, 'Main Menu', 1, 0),
(43, 39, 'Web Development', 1, 45),
(38, 42, 'Internet Marketing', 3, 45),
(40, 43, 'Web Design', 0, 45),
(46, 44, 'SEO', 2, 45),
(50, 49, 'HTML', 0, 40),
(47, 45, 'Web Design Wales', 1, 8);
And I have a Menu_model
Code: <?php
class Menu_model extends CI_Model {
function get_menu_structure(){
//$this->db->where('parent',$parent);
$this->db->order_by('menu_position','asc');
$this->db->join('content', 'content.id = content_menus.content_id', 'left');
$q=$this->db->get('content_menus', 'content');
foreach($q->result() as $r){
$data[$r->parent][] = $r->parent;
}
$menu=$this->build_menu($data);
return $menu;
}
function build_menu($parent){
static $i = 1;
if (isset($parent)) {
$menu = '<ul>';
$i++;
foreach ($parent as $r) {
$child = $this->build_menu($r->menu_id);
$menu .= '<li>';
$menu .= '<a >url_key.'">'.$r->content_menu_title.'link</a>';
if ($child) {
$i--;
$menu .= $child;
}
$menu .= '</li>';
}
$menu .= '</ul>';
return $menu;
} else {
return false;
}
}
}
And a controller
Code: function index()
{
$template = 'page';
$main_menu = $this->menu_model->get_menu_structure();
$data['main_menu'] = $main_menu;
print_r ($main_menu); die();
$data['content'] = '' . $template . '';
//$this->output->cache(60);
$this->load->view('templates/master', $data);
}
And a view with
Code: <?php echo $main_menu; ?>
I'm getting the error:
Code: A PHP Error was encountered
Severity: Notice
Message: Trying to get property of non-object
Filename: models/menu_model.php
Line Number: 25
A PHP Error was encountered
Severity: Notice

Filename: models/menu_model.php
Line Number: 27
etc etc
Can anyone tell me what I'm doing wrong? All I need is a simple recursive menu
