I've installed Joomla v3.4.7 to test and prepare my project.I created a component 'HelloWorld' step by step according the official tutorial [https://docs.joomla.org/J3.x:Developing_an_MVC_Component/Using_the_database][1] ,and I succeeded to show the data list,and then the editing page to add or edit existing data, from the Administrator part, just like
localhost/joomla-test/administrator/index.php?option=com_helloworld
After finishing these, I simply copied the files in /Administrator/components/com_helloworld
to /components/com_helloworld
and overwrite previous files, and access the site component:
localhost/joomla-test/index.php?option=com_helloworld
It didn't work! I used firebug to debug and I got a
NetworkError: 500 Internal Server Error - http://localhost/joomla-test/index.php?option=com_helloworld
error.... What's happened?
My code:
Site/helloworld.php:
<?php
// import joomla controller library
jimport('joomla.application.component.controller');
// Get an instance of the controller prefixed by HelloWorld
$controller = JControllerLegacy::getInstance('HelloWorld');
// Perform the Request task
$controller->execute(JFactory::getApplication()->input->getCmd('task'));
// Redirect if set by the controller
$controller->redirect();
site/controller.php
<?php
// No direct access to this file
defined('_JEXEC') or die;
// import Joomla controller library
jimport('joomla.application.component.controller');
/**
* General Controller of HelloWorld component
*/
class HelloWorldController extends JControllerLegacy
{
/**
* display task
*
* @return void
*/
protected $default_view = 'helloworlds';
public function display($cachable = false)
{
parent::display($cachable);
echo "controller";
return $this;
}
}
site/views/helloworlds/view.html.php:
<?php
// No direct access to this file
defined('_JEXEC') or die;
// import Joomla view library
jimport('joomla.application.component.view');
/**
* HelloWorlds View
*/
class HelloWorldViewHelloWorlds extends JViewLegacy
{
/**
* HelloWorlds view display method
* @return void
*/
function display($tpl = null)
{
// Get data from the model
$items = $this->get('Items');
$pagination = $this->get('Pagination');
// Check for errors.
if (count($errors = $this->get('Errors')))
{
JError::raiseError(500, implode('<br />', $errors));
return false;
}
// Assign data to the view
$this->items = $items;
$this->pagination = $pagination;
// Set the toolbar
$this->addToolBar();
// Display the template
parent::display($tpl);
}
/**
* Setting the toolbar
*/
protected function addToolBar()
{
JToolBarHelper::title(JText::_('COM_HELLOWORLD_MANAGER_HELLOWORLDS'));
JToolBarHelper::deleteList('', 'helloworlds.delete');
JToolBarHelper::editList('helloworld.edit');
JToolBarHelper::addNew('helloworld.add');
}
}
Please help, thank you all.
