To get user's firstname, i can use $USER->firstname the result will be "Teacher 01" (see the red part of the code above)
but how can i get user's role / legacy in moodle? somehow i know it's "moodle/legacy:editingteacher" but how can i either the result is 1 or 0??
I tried to use:
$USER->moodle/legacy:editingteacher No result...
$USER->'moodle/legacy:editingteacher' No result...
$USER->[moodle/legacy:editingteacher] Unexpexted '['
$USER->{moodle/legacy:editingteacher} Unexpected :
$USER->{moodle/legacy->editingteacher} No result...
$USER->{'moodle/legacy:editingteacher'} No Result...


Can anyone help me??
Thanks in advance...

Re: [HELP] Moodle PHP script for user capabilities

Roles are now stored in separate tables in order to make the capability system a lot more flexible.

get_records_sql('SELECT firstname,lastname,role.name FROM '.$CFG->prefix.'user AS user join '.$CFG->prefix.'role_assignments AS role_assignments ON userid=user.id JOIN '.$CFG->role AS role ON roleid=role.id);

Will give you all a row per role assignment, containing the teachers name and the name of the role. What do you want this for? There is a nice has_capability function if you want to check if the user has permission to do something

Thanks, Mike...
I put few text & link in the site's main menu, and i want some menu just can be viewed and used by teachers, some just for students, and some for both.

how do i use this function? in this case i want to check if a user is an admin, editingteacher, teacher, or student

i tried this from acc with editingteacher role:
has capability('editingteacher') return false
has capability('teacher') return false
has capability('editingteacher',NULL,$USER->id) return false

how should i use this funtion? can you give an example?

Thanks in advance... ^^

Re: [HELP] Moodle PHP script for user capabilities

It potentially gets a little difficult, do you have system roles assigned? The reason I ask is that if teachers are not teachers except in the classes they teach then it is a bit difficult to ask 'is this a teacher' on the front page. What I do for things like this is have a system 'staff' role that does this sort of thing (allows access to room booking, shows various links etc.). Then it is a simple case of if(has_capability('[CAPABILITY]',get_context_instance(CONTEXT_SYSTEM)){
should do it.

I can't say I've tried it but I would assume that the menus etc would show up properly only on the front page. (system roles apply everywhere, while frontpage roles only apply when on the front page)

Yeah, but if I assign it to system role, the course became a mess.. For example, i assign teacher 01 and teacher 02 as teacher in system role, an then i assign teacher 01 as teacher in course A...
In front page after a user logged in, Course A will be shown in front page, and there will be 2 Teacher in Course A (Teacher 01 and Teacher 02) instead of just one (Teacher 01).

Oh anyway, do you know how to get to know all course taught by a user and/or all course in which the user is a student? Is there any function in PHP script to know that?

Thanks in advance.

Re: [HELP] Moodle PHP script for user capabilities

What you need is the teacher role assigned only in courses, then make a new 'staff' role that has very few capabilities and assign only this in system context.

Is get_my_courses() what you want? (you can go here and find documentation on all the functions, classes etc in moodle)

hi!


i would like to know all available capabilities. which ones are available?
and this "has_capability" function in the above example: how does it know from which user it checks the capability?

generally i want to find out if a user has "administrator" or at least "high" privileges/capabilities via php.

thanks in advance,
Peter

Picture of Core developers Picture of Documentation writers Picture of Particularly helpful Moodlers Picture of Peer reviewers Picture of Plugin developers
Look on the define roles screen for any role. That list all capabilities.

Alternatively, look at the capabilities table in the DB.

If nothing more specific is available, it sounds like you want moodle/system:config.
