您好这里有在 joomla 中使用 mvc 模式构建表单的官方文档。

表单进入您的 tmp/default.php (site/views/updhelloworld/tmpl/default.php)，然后设置您的操作，当您提交表单时，您将“重定向”到控制器 (site/controllers/updhelloworld.php)，在这里你必须检查你的表格数据

    $data = JRequest::getVar('jform', array(), 'post', 'array');

然后在您的模型中使用该操作

    $upditem        = $model->updItem($data);

在您的模型中，您使用您的数据库。

 public function updItem($data)
    {
    // set the variables from the passed data
    $id = $data['id'];
    $greeting = $data['greeting'];

    // set the data into a query to update the record
            $db             = $this->getDbo();
            $query  = $db->getQuery(true);
    $query->clear();
            $query->update(' #__helloworld ');
            $query->set(' greeting = '.$db->Quote($greeting) );
            $query->where(' id = ' . (int) $id );

            $db->setQuery((string)$query);

    if (!$db->query()) {
        JError::raiseError(500, $db->getErrorMsg());
            return false;
    } else {
            return true;
            }
    }
