我是Joomla的新手，我正在调整我为v1.5编写的外部php类。 基本上，我没有涉及所有细节，我使用一个函数来加载Joomla环境，之后Joomla中的所有内容都可用于该类。 这基本上是使用index.php文件完成的。
它与v1.5一起正常工作并且已经做了一段时间但是试图将其调整为v1.6，它会失败。
这是功能：
private function loadJoomla() {
$path_base = rtrim($this->joomFullPath, '/');
// Set flag that this is a parent file
define( '_JEXEC', 1 );
define( 'DS', DIRECTORY_SEPARATOR );
switch ($joomlaVersion) {
case 'v1.6':
if (file_exists($path_base . '/defines.php')) {
include_once $path_base . '/defines.php';
}
if (!defined('_JDEFINES')) {
define('JPATH_BASE', $path_base);
require_once JPATH_BASE.'/includes/defines.php';
}
require_once JPATH_BASE.'/includes/framework.php';
// Mark afterLoad in the profiler.
JDEBUG ? $_PROFILER->mark('afterLoad') : null;
// Instantiate the application.
$app = JFactory::getApplication('site');
// Initialise the application.
$app->initialise();
// Mark afterIntialise in the profiler.
JDEBUG ? $_PROFILER->mark('afterInitialise') : null;
// Route the application.
$app->route();
// Mark afterRoute in the profiler.
JDEBUG ? $_PROFILER->mark('afterRoute') : null;
// Dispatch the application.
$app->dispatch();
// Mark afterDispatch in the profiler.
JDEBUG ? $_PROFILER->mark('afterDispatch') : null;
// Render the application.
$app->render();
// Mark afterRender in the profiler.
JDEBUG ? $_PROFILER->mark('afterRender') : null;
// Return the response.
return $app;
break;
case 'v1.5':
// PREPARE
define('JPATH_BASE', $path_base);
require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' );
require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' );
JDEBUG ? $_PROFILER->mark( 'afterLoad' ) : NULL;
// CREATE THE APPLICATION
$GLOBALS['mainframe'] =& JFactory::getApplication('site');
// INITIALISE THE APPLICATION
/* set the language */
$GLOBALS['mainframe']->initialise();
JPluginHelper::importPlugin('system');
/* trigger the onAfterInitialise events */
JDEBUG ? $_PROFILER->mark('afterInitialise') : NULL;
$GLOBALS['mainframe']->triggerEvent('onAfterInitialise');
// ROUTE THE APPLICATION
$GLOBALS['mainframe']->route();
/* authorization */
$GLOBALS['Itemid'] = JRequest::getInt( 'Itemid');
$GLOBALS['mainframe']->authorize($GLOBALS['Itemid']);
/* trigger the onAfterRoute events */
JDEBUG ? $_PROFILER->mark('afterRoute') : NULL;
$GLOBALS['mainframe']->triggerEvent('onAfterRoute');
// DISPATCH THE APPLICATION
$GLOBALS['option'] = JRequest::getCmd('option');
$GLOBALS['mainframe']->dispatch($GLOBALS['option']);
/* trigger the onAfterDispatch events */
JDEBUG ? $_PROFILER->mark('afterDispatch') : NULL;
$GLOBALS['mainframe']->triggerEvent('onAfterDispatch');
// RENDER THE APPLICATION
$GLOBALS['mainframe']->render();
/* trigger the onAfterRender events */
JDEBUG ? $_PROFILER->mark('afterRender') : NULL;
$GLOBALS['mainframe']->triggerEvent('onAfterRender');
// RETURN THE RESPONSE
return JResponse::toString($GLOBALS['mainframe']->getCfg('gzip'));
break;
default:
return NULL;
break;
}
如上所述，v1.5位工作正常，只是index.php文件，主机变量为全局变量。 v1.6位落在'$ app-＆gt; dispatch（）;'。
使用'die'调试流程使我在/libraries/joomla/application.php中进行函数调度，在那里我发现掉落点是'$ contents = JComponentHelper :: renderComponent（$ component）;'这让我在/libraries/joomla/application/component/helper.php中运行renderComponent
一些'死'之后，我发现了摔倒点，等待它，'ob_start（）;'。 完全困惑，特别是自检查v1.5代码以来，我可以看到它与v1.6完全相同。
我怀疑$ app范围可能是背后的原因，并会感谢一些帮助。我尝试了明显的“$ GLOBALS ['app']”，没有任何快乐。
感谢您抽出宝贵的时间和精力。

我设法解决了这个问题如下。
发生了两个不同的问题。
首先，v1.6部分没有正确初始化“$ option”参数。感谢this query I made中的用户hbit，我能够解决这个问题。通过更改代码如下：
// Dispatch the application.
$option = JRequest::getCmd('option');
$app->dispatch($option);
然而，这并没有解决问题，代码仍然在'ob_start'点崩溃。
其次，我无法了解崩溃的实际原因，但是找到了解决方法。由于位于/libraries/joomla/application/component/helper.php中的ob_start位仅用于将组件输出收集到变量中，因此我通过拉动'$ app-＆gt; dispatch的代码解决了这个问题。 （$ option）'触发我的文件并修改问题部分。
首先，我修改了主要部分如下：
// Dispatch the application.
$option = JRequest::getCmd('option');
/** The process crashes here for some reason
* (See https://stackoverflow.com/questions/7039162/).
* So we comment out the Joomla! function, pull the code in here and
* push the component content into the Joomla document buffer ourselves.
**/
//$app->dispatch($option);
$this->joomdispatch($option);
然后我写了一个'joomdispatch'函数如下：
private function joomdispatch($option) {
/************************
* This is pulled from function 'render'
* in /libraries/joomla/application.php
************************/
$document = JFactory::getDocument();
$document->setTitle(JApplication::getCfg('sitename'). ' - ' .JText::_('JADMINISTRATION'));
$document->setDescription(JApplication::getCfg('MetaDesc'));
/************************
* This is pulled from function 'renderComponent'
* in /libraries/joomla/application/component/helper.php
* Function 'renderComponent' is called by the
* '$contents = JComponentHelper::renderComponent($component);' line
* We exclude that line and jump to the function code
************************/
// Initialise variables.
$app = JFactory::getApplication();
// Load template language files.
$template = $app->getTemplate(true)->template;
$lang = JFactory::getLanguage();
$lang->load('tpl_'.$template, JPATH_BASE, null, false, false)
|| $lang->load('tpl_'.$template, JPATH_THEMES."/$template", null, false, false)
|| $lang->load('tpl_'.$template, JPATH_BASE, $lang->getDefault(), false, false)
|| $lang->load('tpl_'.$template, JPATH_THEMES."/$template", $lang->getDefault(), false, false);
$scope = $app->scope; //record the scope
$app->scope = $option; //set scope to component name
// Build the component path.
$option = preg_replace('/[^A-Z0-9_\.-]/i', '', $option);
$file = substr($option, 4);
// Define component path.
define('JPATH_COMPONENT', JPATH_BASE.DS.'components'.DS.$option);
define('JPATH_COMPONENT_SITE', JPATH_SITE.DS.'components'.DS.$option);
define('JPATH_COMPONENT_ADMINISTRATOR', JPATH_ADMINISTRATOR.DS.'components'.DS.$option);
// get component path
if ($app->isAdmin() && file_exists(JPATH_COMPONENT.DS.'admin.'.$file.'.php')) {
$path = JPATH_COMPONENT.DS.'admin.'.$file.'.php';
} else {
$path = JPATH_COMPONENT.DS.$file.'.php';
}
$task = JRequest::getString('task');
// Load common and local language files.
$lang->load($option, JPATH_BASE, null, false, false)
|| $lang->load($option, JPATH_COMPONENT, null, false, false)
|| $lang->load($option, JPATH_BASE, $lang->getDefault(), false, false)
|| $lang->load($option, JPATH_COMPONENT, $lang->getDefault(), false, false);
// Handle template preview outlining.
$contents = null;
// Get component html
/************************
* This has been edited from the native 'ob_start'.
* Could use curl as well
***********************/
$contents = file_get_contents($this->joomUrl . '/index.php?' . $this->joomQS);
// Build the component toolbar
jimport('joomla.application.helper');
if (($path = JApplicationHelper::getPath('toolbar')) && $app->isAdmin()) {
// Get the task again, in case it has changed
$task = JRequest::getString('task');
// Make the toolbar
include_once $path;
}
$app->scope = $scope; //revert the scope
/************************
* Back to function 'renderComponent' code
* to complete process
************************/
$document->setBuffer($contents, 'component');
// Trigger the onAfterDispatch event.
JPluginHelper::importPlugin('system');
JApplication::triggerEvent('onAfterDispatch');
}
有了这个，一切正常。没有得到（奇怪的）错误的底部，但设法解决它。
