III. MOODLE TIZIMIDA DASTURIY KOMPONENTA (PLAGIN) YARATISH VA O’RNATISH

Moodle tizimi uchun PHP tilida plagin yaratish texnologiyasi.

LMS moodle tizimida plagin yaratish uchun albatta php texnologiyasidan foydalaniladi shu uchun biz quyidagi php kodlar asosida LMS moodle tizimida plaginni qanday yaratishni ko’rib chiqamiz:

class block_graph_stats extends block_base {

/*

* Standard block API function for initializing block instance

* @return void

*/

public function init() {

$this->title = get_string('blockname', 'block_graph_stats');

'site' => true,

'course-view' => true);

}

$this->page->requires->jquery();

}

public function get_content() {

global $CFG, $COURSE, $USER, $DB;

if ($this->content !== null) {

return $this->content;

}
