Overriding an abstract class in a theme

Overriding an abstract class in a theme

Hi!

I try to override in my theme the function section_header in the abstract class format_section_renderer_base located in 

course/format/renderer.php

I do not know what class name I need to declare in my new class. Can I extend an abstract class btw?

abstract class theme_test_core_course_format_renderer extends format_section_renderer_base
or

abstract class theme_test_format_section_renderer_base extends format_section_renderer_base
or ?
What is the name of the file of the renderer, abstract class of path of the class (
format_section_renderer_base or core_course_format_renderer) ?

Some incomplete information have been already given here
https://moodle.org/mod/forum/discuss.php?d=396419

I have followed the process https://docs.moodle.org/dev/Overriding_a_renderer#Overriding_a_component.27s_renderer
Moodle 3.9 with lambda theme.

Thanks for your support

In fact I am confused as the renderer class does not follow the physical path of the files course_format_renderer / format_section_renderer_base... I have tried with both without success. There's no example in this case in the official documentation.

renderers.php

require_once('renderers/core_renderer.php');
require_once('renderers/core_course_renderer.php');
require_once('renderers/mod_assign_renderer.php');
require_once('renderers/format_section_renderer_base.php');


format_section_renderer_base.php in folder "renderers"

defined('MOODLE_INTERNAL') || die();

require_once($CFG->dirroot . "/course/format/renderer.php");
abstract class theme_lambda_format_section_renderer_base extends format_section_renderer_base {
...
}

$THEME->rendererfactory = 'theme_overridden_renderer_factory'; is set obviously in config.php...

abstract? Your class should override the course format version not the base class. To learn about OO in PHP see: https://www.php.net/manual/en/language.oop5.php - to learn about how Moodle autoloads and extends classes, see: https://docs.moodle.org/dev/Automatic_class_loading.
