将Joomla 1.5组件更新为Joomla 2.5组件的步骤

Question

请提供步骤将Joomla 1.5组件更新为Joomla 2.5组件.

先感谢您.

Answer 1

在适应1.5到1.6以及此DVLancer博客中有很多东西需要学习:

全局变量$ mainframe和$ option

Joomla 1.5

global $mainframe, $option;

Joomla 2.5换成了

$mainframe =& JFactory::getApplication();
$option = JRequest::getCmd('option');

要么

$option = $this->option //If the code is in a controller class derived from JControllerForm

在模板中获取页面标题*

Joomla 1.5

global $mainframe;
$mainframe = &JFactory::getApplication();
$page_title = $mainframe->getPageTitle();

在Joomla 2.5中替换为

$app =& JFactory::getDocument();
$page_title = $app->getTitle();

模板路径

**Joomla 1.5

"templates/templatename/"

Joomla 2.5

$app= & JFactory::getApplication();
$template = $app->getTemplate();

要么

"templates/".$this->template."/"

如何确定您是否在主页上

Joomla 1.5

if( JRequest::getVar('view') == "frontpage" ) {
  // You are on the home page
} else {
  // You are not 
}

Joomla 2.5

$menu =& JSite::getMenu(); // get the menu
$active = $menu->getActive(); // get the current active menu
if ( $active->home == 1 ) { // check if this is the homepage
  // You are on the home page
} else {
  // You are not
}

访问错误变量

Joomla 1.5

$code = $this->error->code;
$message = $this->error->message;

在Joomla 2.5中,这些变量现在是私有的,必须通过getter方法访问以避免以下错误: PHP cannot acess protected property error

$code = $this->error->getCode();
$message = $this->error->getMessage();
