如何添加添加到管理员的链接category_id ?(Joomla 2.5)
你可以写在函数JToolBarHelper::addNew('select.add');
或其他函数中......例如,
index.php?option=com_pictures&view=select&layout=edit& category_id =14
请帮忙。提前致谢
回复大卫 F:
嗨,大卫 F。我几乎明白了。
点击“添加”后出现category_id=14
,其余点击“编辑”、“保存”、“保存关闭”... -category_id=0
我一直在编程。这是一个例子:
...
protected $catid;
public function __construct($config = array()) {
parent::__construct($config);
if (empty($this->catid)) {
$this->catid = JRequest::getInt('category_id', 0);
}
}
protected function allowAdd($data = array()) {
$user = JFactory::getUser();
$categoryId = JArrayHelper::getValue($data, 'catid', JRequest::getInt('filter_category_id'), 'int');
$allow = null;
if ($categoryId) {
$allow = $user->authorise('core.create', $this->option . '.category.' . $categoryId);
}
if ($allow === null) {
return parent::allowAdd($data);
} else {
return $allow;
}
}
protected function allowEdit($data = array(), $key = 'id') {
$recordId = (int) isset($data[$key]) ? $data[$key] : 0;
$categoryId = 0;
if ($recordId) {
$categoryId = (int) $this->getModel()->getItem($recordId)->catid;
}
if ($categoryId) {
return JFactory::getUser()->authorise('core.edit', $this->option . '.category.' . $categoryId);
} else {
return parent::allowEdit($data, $key);
}
}
protected function getRedirectToItemAppend($recordId = null, $urlVar = 'id') {
$append = parent::getRedirectToItemAppend($recordId);
$append .= '&category_id=' . $this->category_id;
return $append;
}
protected function getRedirectToListAppend() {
$append = parent::getRedirectToListAppend();
$append .= '&category_id=' . $this->category_id;
return $append;
}
