Calling core_course_renderer::get_category_formatted_description() - Moodle 3.10+

Calling core_course_renderer::get_category_formatted_description() - Moodle 3.10+

Hi all,

I seem to be having a bit of brain fade trying to use the method core_course_renderer::get_category_formatted_description()

However I get the error - Call to undefined method core_course_renderer::get_category_formatted_description() from the course lib.php

The php code is:    

$output .= core_course_renderer::get_category_formatted_description($cat->id);
The error is:

Error

Exception - Call to undefined method core_course_renderer::get_category_formatted_description()
Debug info:
Error code: generalexceptionmessage
Stack trace:
  • line 142 of /theme/mytheme/lib.php: Error thrown
  • line 49 of /theme/mytheme/layout/frontpage.php: call to theme_horn_getcourses()
  • line 1374 of /lib/outputrenderers.php: call to include()
  • line 1304 of /lib/outputrenderers.php: call to core_renderer->render_page_layout()
  • line 100 of /index.php: call to core_renderer->header()

I'm sure I'm missing something obvious but any help greatfully received.

Thanks

Dave

Addendum - I'm simply trying to display the category information correctly.

You're trying to call for a static function and  the function get_category_formatted_description isn't static.

There's actually a call to the function in the course renderer that you can use as a reference and do something like, it's implemented like this:

$chelper = new coursecat_helper();
$chelper->get_category_formatted_description($cat->id);

Thanks for getting back to me. I tried this and, for some reason it doesn't return the description. I guess I'm not calling it correctly?

Cheers

Hi Dave,

As Lior said, you can't call this method statically, it should be called from an instantiated coursecat_helper class
What does your code look like?

Hi Paul,

Pretty much as per Lior's example at the moment.

mytheme/lib.php contains:
---------------------------------------------------
function theme_horn_getcourses() {
global $DB;
$output = "";
$table = "course_categories";
$params = array('id'=>1);
$sql = "SELECT * FROM {course_categories} WHERE id > :id ORDER BY idnumber ";
$categories = $DB->get_records_sql($sql, $params);
foreach($categories as $cat) {
$output .= '<div class="horn_sep_category"> <div class="horn_category_header"> <h3>'.$cat->name.'</h3><span class="horn_click_to_open"<%gt;i class="horn-toggle-icon fa fa-angle-down fa-3x fa-rotate-180"><i></span> </div>';
$chelper = new \coursecat_helper();
$description = $chelper->get_category_formatted_description($cat->id);
$output .= $description ;
$output .= theme_horn_getcourses_by_category($cat->id);
$output .= ' </div>';
}

return $output;
}
-----------------------------------------------------------------

...which gets the code from the database OK but injects:
<p dir="ltr" style="text-align:left;"> <img src="@  @  PLUGIN FILE @ @/Sealion-Yawns.JPG?time=1634733374402" alt="" class="img-fluid atto_image_button_left" width="476" height="317">sdgf sdsdf uif uishfui haduisfui hsdifu hsdfuihsdfuihsidfuhsduifhsuifhsuifh yu u fu8ygf uyguy guygffrwugrueryyuwegrur yuweruyweruywe.
So I know I need to run it through get_category_formatted_description but can't see how.

Cheers

Dave

I've got it working by looking at the /course/renderer.php file and taking its guts out:

$context = context_coursecat::instance($cat->id);
$output .= file_rewrite_pluginfile_urls($cat->description,
'pluginfile.php', $context->id, 'coursecat', 'description', null);


Would the code provided above by Lior be more efficient? Better?

Cheers

Dave
