== 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".

== How can I check required variables like "Course Module ID" and "widget ID"? ==
A: Use
<code php>$id = optional_param('id', 0, PARAM_INT); // Course Module ID</code> or
<code php>$a = optional_param('a' , 0, PARAM_INT); // widget ID</code>
An example of use of these two checks can be easily found in your moodle/mod/widget/view.php (rows 15 to 41).

'''Warning''': If you miss this step, the file can be called directly by writing the address in the web browser and unauthorized users can get them.

== Are some more variables needed to check for security reasons? ==
A: ???????????

== What is provided "for free" by the Moodle environment? That is, which set of variables are provided as "ready to use"? ==
A: You have availability of all the global Moodle variables ($CFG->xxx), the object $USER (in which all the information the current user entered in his/her login form is saved).
Moreover, you have the availability of the $course array and of some information about your specific widget module.
The following is a description of the variables you are free to use:
<code php>$CFG->$USER
$course->id
$cm->id</code>
There are a lot more variables that are beyong the scope of this Moodle docs page that are, for this reason, going to be neglected.
Belonging to this list of neglected variables, for instance, is $THEME, $???.
Some examples:
<code php>if ($CFG->xxx == '') {

}</code>

== Why is this set of variables so important? ==
A: At any moment you may need to:
*reload the widget page
To call the instance of you module page, you need to call:
<code php>$CFG->wwwroot.'/mod/newmodule/view.php?id='.$cm->id</code>
$cm stands for course module (Is this true??????????)
*return to the main course page
To return back to the course page, you need to call:
<code php>$CFG->wwwroot.'/course/view.php?id='.$course->id</code>
