Library Tree Menu Codeigniter

Hi guys, kali ini saya akan berbagi library Tree menu untuk kebutuhan untuk project website atau blog dengan menggunakan framework Codeigniter.

Ok, kita langsung saja siapkan table untuk media penymipanan menu. Berikut struktrnya :

DROP TABLE IF EXISTS `menus`;
CREATE TABLE `menus` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(50) NOT NULL,
`parent_id` int(11) NOT NULL DEFAULT '0',
`module` varchar(255) DEFAULT NULL,
`url` varchar(255) DEFAULT NULL,
`type` varchar(255) DEFAULT 'front' COMMENT 'front, backend',
`active` int(2) NOT NULL DEFAULT '1',
`order` int(2) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=0 DEFAULT CHARSET=utf8;


Selanjutnya berikut script/code library Tree Menu :

'; //parent tag open
private $pt_close = ''; //parent tag close
private $pt_slink = ''; //parent tag link
private $pt_attr = ''; /parent attribute
private $lpt_open = '

'; //list parent tag open
private $lpt_close = '

'; //list parent tag close

/*child properties*/
private $ct_open = '

'; //child tag open private $ct_close = '

'; //child tag close
private $ct_attr = ''; //child tag attribute
private $lct_open = '

'; //list child tag open
private $lct_close = '

'; //list child tag close

var $obarray, $list;

public function __construct($properties = array())
{
empty($properties) OR $this->initialize($properties, FALSE);
$this->_mimes =& get_mimes();
$this->_CI =& get_instance();
log_message('info', 'Menu Class Initialized');
}

public function initialize(array $properties = array()){
foreach ($properties as $key => $val)
{
if (property_exists($this, $key))
{
$this->$key = $val;
}
}
}

function buildTree($menu_array)
{
global $obarray, $list;

$list = $this->pt_open;

if (!is_array($menu_array)) return '';

$obarray = $menu_array;

foreach($obarray as $item){
if($item['parent'] == 0){
$mainlist = $this->_buildElements($item, 0);
}
}

$list .= $this->pt_close;

return $list;
}

private function _buildElements($parent, $append)
{
global $obarray, $list;

if($parent['module']!='pages'){
if($this->_hasChild($parent['id'])){
$list .= $this->lpt_open . anchor($parent['module'], $parent['name'].$this->pt_attr, $this->pt_slink);
}else{
$list .= $this->lct_open . anchor($parent['module'], $parent['name'], '') . $this->lct_close;
}
}else{
if($this->_hasChild($parent['id'])){
$list .= $this->lpt_open . anchor($parent['module'].'/'.$parent['url'], $parent['name'].$this->pt_attr, $this->pt_slink);
}else{
$list .= $this->lct_open . anchor($parent['module'].'/'.$parent['url'], $parent['name'], '') . $this->lct_close;
}
}

if($this->_hasChild($parent['id'])){
$append++;
$list .= $this->ct_open;
$child = $this->_buildArray($parent['id']);

foreach($child as $item){
$list .= $this->_buildElements($item, $append);
}

if($this->_hasChild($parent['id'])){
$list .= $this->lpt_close;
}

$list .= $this->ct_close;
}
}

private function _hasChild($parent)
{
global $obarray;
$counter = 0;
foreach($obarray as $item){
if($item['parent'] == $parent){
++$counter;
}
}
return $counter;
}

private function _buildArray($parent)
{
global $obarray;
$bArray = array();

foreach($obarray as $item){
if($item['parent'] == $parent){
array_push($bArray, $item);
}
}

return $bArray;
}
}


Cara menggunakan sebagai berikut:


load->library(‘omenu’);
}

Public function index()
{
$data[‘menu’] = $this->get_menus();
$this->load->view(‘halama_utama’,$data);
}

Public function get_menus()
{
$properties = array(
'pt_open' => '

', 'pt_close' => '

',
'pt_slink' => 'class="dropdown-toggle" data-toggle="dropdown"',
'pt_attr' => ' ',
'lpt_open' => '

',
'lpt_close' => '

',
'ct_open' => '

', 'ct_close' => '

',
'ct_attr' => '',
'lct_open' => '

',
'lct_close' => '

'
);

$this->load->library('omenu', $properties);
$this->omenu->initialize($properties);
$this->db->where('active', 1);
$menu = $this->db->get('menus')->result_array();
return $this->omenu->buildTree($menu);
}
}

Lalu kita buat view,

<….. tag html….>

<….. tag html….>


Mudah bukan… semoga bermaafat. Sampai jumpa pada artikel berikutnya.
