【问题描述】:
我正在寻找如何从 joomla 前端保存数据的解决方案。我遇到了以下完美运行的控制器和模型代码。但我一直在寻找一种标准做法,就像它在后端使用 jform、jtable 等完成的那样……在下面的代码(模型内部)中,保存技术看起来并不那么吸引人。而且我完全不知道服务器端验证是如何实现的。
这可能会令人困惑,所以我想重申一下,在后端我们甚至不必编写添加、保存或更新函数,它由核心类自动处理,并具有客户端和服务器端验证。所以我一直在寻找类似的东西。
控制器
<?php
// No direct access.
defined('_JEXEC') or die;
// Include dependancy of the main controllerform class
jimport('joomla.application.component.controllerform');
class JobsControllerRegistration extends JControllerForm
{
public function getModel($name = 'Registration', $prefix = 'JobsModel', $config = array('ignore_request' => true))
{
return parent::getModel($name, $prefix, array('ignore_request' => false));
}
public function submit()
{
// Check for request forgeries.
JRequest::checkToken() or jexit(JText::_('JINVALID_TOKEN'));
// Initialise variables.
$app = JFactory::getApplication();
$model = $this->getModel('Registration');
// Get the data from the form POST
$data = JRequest::getVar('jform', array(), 'post', 'array');
$form = $model->getForm();
if (!$form) {
JError::raiseError(500, $model->getError());
return false;
}
// Now update the loaded data to the database via a function in the model
$upditem = $model->updItem($data);
// check if ok and display appropriate message. This can also have a redirect if desired.
if ($upditem) {
echo "<h2>Joining with us is successfully saved.</h2>";
} else {
echo "<h2>Joining with us faild.</h2>";
}
return true;
}
}
型号
<?php
// No direct access to this file
defined('_JEXEC') or die('Restricted access');
// Include dependancy of the main model form
jimport('joomla.application.component.modelform');
// import Joomla modelitem library
jimport('joomla.application.component.modelitem');
// Include dependancy of the dispatcher
jimport('joomla.event.dispatcher');
/**
* HelloWorld Model
*/
class JobsModelRegistration extends JModelForm
{
/**
* @var object item
*/
protected $item;
/**
* Get the data for a new qualification
*/
public function getForm($data = array(), $loadData = true)
{
$app = JFactory::getApplication('site');
// Get the form.
$form = $this->loadForm('com_jobs.registration', 'registration', array('control' => 'jform', 'load_data' => true),true);
if (empty($form)) {
return false;
}
return $form;
}
//Nwely added method for saving data
public function updItem($data)
{
// set the variables from the passed data
$fname = $data['fname'];
$lname = $data['lname'];
$age = $data['age'];
$city = $data['city'];
$telephone = $data['telephone'];
$email = $data['email'];
$comments = $data['comments'];
// set the data into a query to update the record
$db = $this->getDbo();
$query = $db->getQuery(true);
$query->clear();
$db =& JFactory::getDBO();
$query = "INSERT INTO #__joinwithus ( `id`, `firstname`, `lastname`, `age`, `city`, `telephone`, `email`, `comment`)
VALUES (NULL,'" . $fname . "','" . $lname . "','" . $age . "','" . $city . "','" . $email . "','" . $telephone . "','" . $comments . "')";
$db->setQuery((string)$query);
if (!$db->query()) {
JError::raiseError(500, $db->getErrorMsg());
return false;
} else {
return true;
}
}
}
谁能给我指点一个好的教程或分享一个使用 joomla 2.5 在前端处理表单的组件。
