如何在Joomla中获取文章的参数?

I am trying to design the article page of JOOMLA 3.1, but I haven't managed to succeed. How can I achieve this? And how can I get the parameters of an article?

Like, when I have article test I want to do something like this

$this->article->get('title');

I already tried to Google but I can't find any proper information. Is there someone who can explain this to me?

To change the design, you should do a Template Override

Then, you will see in:

components/com_content/views/article/tmpl/default.php

that the params are defined and called like so: `

$params  = $this->item->params;

$var1 = $params->get('param_name_1');
$var2 = $params->get('param_name_2');
$var3 = $params->get('param_name_3');
