Admins can see hidden course and teachers cannot.

Change moodle/course:viewhiddencourses from inherit to allow

Jenny

'moodle/user:viewhiddendetails' => array(

'riskbitmask' => RISK_PERSONAL,

'captype' => 'read',
'contextlevel' => CONTEXT_SYSTEM,
'legacy' => array(
'teacher' => CAP_ALLOW,
'editingteacher' => CAP_ALLOW,
'coursecreator' => CAP_ALLOW,
'admin' => CAP_ALLOW
)
),

'moodle/course:viewhiddencourses' => array(

'captype' => 'read',
'contextlevel' => CONTEXT_COURSE,
'legacy' => array(
'admin' => CAP_ALLOW
)
),

If you execute this SQL query:

INSERT INTO `mdl_role_capabilities` ( `id` , `contextid` , `roleid` , `capability` , `permission` , `timemodified` , `modifierid` )
VALUES (
NULL , '1', '3', 'moodle/course:viewhiddencourses', '1', '1172197664', '0'
);

The problem seems to be solved (at least on my install). If you want to show the course to editing teachers only, then substitute '2' for the '3'.

I have a problem making a proper patch out of this though. If some kind soul answered the questions at http://moodle.org/mod/forum/discuss.php?d=65584 I could do it though.

• setting both the moodle/category:visibility and moodle/course:viewhiddencourses permissions to teachers (as in the proposed bugfix and the comment from Jenny Toller)
• creating a role with only those permissions and assigning teachers from the hidden categories and courses to it at the site level
• creating several combinations of depth in categories and courses (0 to 3)
  even then invisible categories and courses remained only visible to the administrator.

Since I manage a Moodle site with this version and it's already being used by students at my university the matter became rather urgent. Giving administration privileges to all teachers that had courses to prepare was clearly not an option. I decided to look in the code and try my best to find a potential solution.

Notice: I do not claim this to be a good solution. I'm NOT a Moodle expert, far from it . However, I have tested this code thoroughly and I believe it to be a possible bugfix and perhaps close this bug.

I commented all insertions and modifications in the code. I left all previous functionality untouched. Forgive me if I do not follow Moodle coding conventions. Feel free to try this patch at your own risk

• View hidden courses (moodle/course:viewhiddencourses)
• See hidden categories (moodle/category:visibility)
  by setting them both to Allow.

2) Assign that Role to the users that should see hidden categories and courses IN THE LEVEL from which they should see them.

Example:
A site with 2 categories and 3 courses:
CategoryA [visible]

• Course1 [visible]
• Course2 [invisible]
  CategoryB [invisible]
• Course3 [invisible]

Considering that you created a role called SeeHidden with the above permissions set to allow the possible scenarios are:
a) you want to let the user se ALL hidden courses and categories
-> Assign the role SeeHidden site wide
Result: User will see Course2, CategoryB and Course3

b) you want the user to see onlu Course2
-> Assign the role SeeHidden to CategoryA
Result: as expected...

c) you want the user to see Course3
-> Assign the role SeeHidden to CategoryB... BUT this alone will not solve your problem. The user must see the hidden category also. One possible way to address this issue would be to create a role that allows the user to see hidden categories only and make it site wide for him.
Result: User will see CategoryB and Course3 as well as all other hidden courses and categories below this one (to avoid the categories part you can choose to prohibit the site wide role mentioned before)

I hope this helps.

André

Thanks in advance.

Look for

View hidden courses
moodle/course:viewhiddencourses

on the page. Just do a search for either of these and you should fine it!

Yu

Thanks for the fast response, however I don't have any moodle/course permissions in my mdl_capabilities db table, so they are not appearing on the page. Strangely, my auto-increment keys in mdl_capabilities start from 78, so it looks like I am missing a whole bunch of permissions in this table. I think I have found what they are meant to be (documented in lib/db/access.php), but I'm not sure how to load them in to the table quickly. I'll look in to it. I might need to do a fresh install of 1.7 and see what data I'm missing.

Thanks for your help
