同樣 JController 是MVC中重要的起點,正式這個類決定的動作的下一步流向,我們來看看錶格提交數據的典型的controller的代碼:
function edit()
{
JRequest::setVar( 'view', 'hello' );
JRequest::setVar( 'layout', 'form' );
JRequest::setVar('hidemainmenu', 1);
parent::display();
}
/**
* save a record (and redirect to main page)
* @return void
*/
function save()
{
$model = $this->getModel('hello');
if ($model->store($post)) {
$msg = JText::_( 'Greeting Saved!' );
} else {
$msg = JText::_( 'Error Saving Greeting' );
}
// Check the table in so it can be edited.... we are done with it anyway
$link = 'index.php?option=com_hello';
$this->setRedirect($link, $msg);
}
/**
* remove record(s)
* @return void
*/
function remove()
{
$model = $this->getModel('hello');
if(!$model->delete()) {
$msg = JText::_( 'Error: One or More Greetings Could not be Deleted' );
} else {
$msg = JText::_( 'Greeting(s) Deleted' );
}
$this->setRedirect( 'index.php?option=com_hello', $msg );
}
/**
* cancel editing a record
* @return void
*/
function cancel()
{
$msg = JText::_( 'Operation Cancelled' );
$this->setRedirect( 'index.php?option=com_hello', $msg );
}
實際上 controller 跟提交的task參數,調用controller中的不同的函數,當然默認會調用display ,我覺得還需要記住的就是
getModel ,和setRedirect ,其餘函數用到再看就可以了。
