Q: Where do I have to start?

A: The content of your module is in moodle/mod/widget/view.php If you look inside that file you will find the row: "Write your code here".

Q: How can I check required variables like "Course Module ID" and "widget ID"?

A: Use $id = optional_param('id', 0, PARAM_INT); // Course Module ID, or $a = optional_param('a' , 0, PARAM_INT); // widget ID An example of use of these two check can be easily found in your moodle/mod/widget/view.php (row 15 to 41) If you miss this step, the file can be called directly by writing their address in the web browser and unauthorized user can get them.
