Hi there everyone im new to PHP and Joomla and I have developed a component in Joomla but my code is giving me errors. I have tried to solve the problem but I’am unable to solve it. So can anyone suggest me what is the problem with my code? Thanks in advance.
Here are my two files:
1st view.html.php
defined('_JEXEC') or die('=;)');
jimport('joomla.application.component.view');
class namnamViewlistrestaurant extends JView
{
function display($tpl = null)
{
$item = 'item';
RestUser::RestrictDirectAccess();
//-- Custom css
JHTML::stylesheet( 'style.css', 'components/com_namnam/assets/css/' );
$cuisine=Lookups::getLookup('cuisine');
$lists['cuisine'] = JHTML::_('select.genericlist', $cuisine, 'idcuisine[]', 'class="inputbox" size="7"', 'value', 'text', $item->idcuisine);
$category=Lookups::getLookup('restcategory');
$lists['category'] = JHTML::_('select.genericlist', $category, 'idcategory[]', 'class="inputbox" multiple="multiple" size="7"', 'value', 'text', $item->idcategory);
$items = & $this->get('Data');
$pagination =& $this->get('Pagination');
$lists = & $this->get('List');
$this->assignRef('items', $items);
$this->assignRef('pagination', $pagination);
$this->assignRef('lists', $lists);
parent::display($tpl);
}//function
}//class
And 2nd is listrestaurant.php
defined('_JEXEC') or die('=;)');
jimport('joomla.application.component.model');
class namnamModellistrestaurant extends JModel
{
var $_data;
var $_total = null;
var $_pagination = null;
function __construct()
{
parent::__construct();
global $mainframe, $option;
$limit = $mainframe->getUserStateFromRequest( 'global.list.limit', 'limit', $mainframe->getCfg('list_limit'), 'int' );
$limitstart = $mainframe->getUserStateFromRequest( $option.'.limitstart', 'limitstart', 0, 'int' );
$limitstart = ($limit != 0 ? (floor($limitstart / $limit) * $limit) : 0);
$this->setState('limit', $limit);
$this->setState('limitstart', $limitstart);
}
function _buildQuery()
{
$where = array();
$where[]=" idowner=".RestUser::getUserID()." ";
if ($this->search)
{
$where[] = 'LOWER(name) LIKE \''. $this->search. '\'';
}
$where =( count($where) ) ? ' WHERE ' . implode( ' AND ', $where ) : '';
$orderby = '';
#_ECR_MAT_FILTER_MODEL1_
if (($this->filter_order) && ($this->filter_order_Dir))
{
$orderby = ' ORDER BY '. $this->filter_order .' '. $this->filter_order_Dir;
}
$this->_query = ' SELECT *'
. ' FROM #__namnam_restaurants '
. $where
. $orderby
;
return $this->_query;
}
function getData()
{
if (empty($this->_data))
{
$query = $this->_buildQuery();
$this->_data = $this->_getList($query, $this->getState('limitstart'), $this->getState('limit'));
}
return $this->_data;
}
function getList()
{
// table ordering
$lists['order_Dir'] = $this->filter_order_Dir;
$lists['order'] = $this->filter_order;
// search filter
$lists['search']= $this->search;
return $lists;
}
function getTotal()
{
// Load the content if it doesn't already exist
if (empty($this->_total))
{
$query = $this->_buildQuery();
$this->_total = $this->_getListCount($query);
}
return $this->_total;
}
function getPagination()
{
// Load the content if it doesn't already exist
if (empty($this->_pagination))
{
jimport('joomla.html.pagination');
$this->_pagination = new JPagination($this->getTotal(), $this->getState('limitstart'), $this->getState('limit') );
}
return $this->_pagination;
}
}//class
