Question

我有一个要修改Joomla表单值的问题。当我点击Joomla保存按钮时，我首先要修改表单值，然后通过模型保存它。为此，我尝试在控制器中获取表单值，然后将该值传递给模型。值已成功打印为数组，但无法迭代该数组。

我在控制器中获取表单值的代码

public function save()
{
  $app  = JFactory::getApplication();
  $model    = $this->getModel('HelloWorld');

  // Get the data from the form POST
  $data = JRequest::get('post');

  //var_dump($data); die();
      // Now update the loaded data to the database via a function in the model
      $res  = $model->save($data);

  return true;
}

然后将数据作为数组传递给这样的模型

public function save($data)
    {
        print_r($data);//it is bening printed successfully
        echo 'Greeting: ' .  $data['greeting'];//it is not being printed as I want to fetch
    }

print_r($data)显示的数组是这样的

Array ( [jform] => Array ( [id] => [greeting] => Hahaha ) [task] => helloworld.save [4f80fadfc470fa5addfe322aeb6256d6] => 1 )

所有我想迭代的数组并获得问候值，然后在修改后将其保存在数据库中

如何覆盖Joomla保存功能？
