How to override the getDescription() method in Joomla?

Question

PHP

There is a question about CMS Joomla 3.15 - there is a method in Joomla $document->getDescription();that takes the first 200 characters from the article and inserts them into the description meta tag. How can I override this method to take the first 300 characters from the article? And where can I find where this method is described? In what file?

Answer 1

search does not work for all files on the line "getDescription(" ?

Answer 2

Install NetBeans for yourself, load all your joomla into a new project and then you can simply click on the method and you will be taken to the file where it is implemented.

Answer 3

/libraries/joomla/document/document.php

public function getDescription()
  {
    return $this->description;
  }

Looks like you need to look further.
