我正在按照Joomla 1.6 Documentation实现一个自定义 MVC 组件。
我在尝试使用JCategories::get()
从com_component
. 我收到以下错误:
PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 125306881 bytes)
如果我不发出 aprint_r($this->items);
来列出项目,我不会收到错误。如果我换行
$categories = JCategories::getInstance('Content');
读书
$categories = JCategories::getInstance('banners');
我没有收到错误。
我在下面包含了我所有的自定义组件代码。仅供参考,过去几天我在 irc.freenode.net/#joomla 上与任何愿意提供帮助但进展甚微的人交谈。任何帮助将非常感激。
控制器代码:
<?php
// No direct access to this file
defined('_JEXEC') or die('Restricted access');
// import joomla controller library
jimport('joomla.application.component.controller');
$controller = JController::getInstance('CtItem');
$controller->execute(JRequest::getCmd('task'));
$controller->redirect();
型号代码:
<?php
// No direct access to this file
defined('_JEXEC') or die;
// import Joomla Categories library
jimport( 'joomla.application.categories' );
class CtItemModelCtItem extends JModel
{
private $_items = null;
private $_parent = null;
public function getItems($recursive = false)
{
$categories = JCategories::getInstance('Content');
$this->_parent = $categories->get(15);
if(is_object($this->_parent))
{
$this->_items = $this->_parent->getChildren($recursive);
}
else
{
$this->_items = false;
}
return $this->_items;
}
}
查看代码:
<?php
// No direct access to this file
defined('_JEXEC') or die('Restricted access');
// import Joomla view library
jimport('joomla.application.component.view');
class CtItemViewCtItem extends JView
{
// Overwriting JView display method
function display($tpl = null)
{
// Assign data to the view
$this->items = $this->get('Items');
if(count($errors = $this->get('Errors')))
{
JError::raiseError(500, implode('<br />', $errors));
return false;
}
// Display the view
parent::display($tpl);
}
}
模板代码:
<?php
// No direct access to this file
defined('_JEXEC') or die('Restricted access');
$document = JFactory::getDocument();
?>
<div id="Test"><?=print_r($this->items, true)?></div>
