Moodle in English: Conditional activities: Activity Locking not working on localhost

Hello,

I hav installed Moodle 1.9.5+ on my laptop(standalone). It is working fine. I tried to add ActivityLocking plugin feature but this features is not getting installed. Even after following the steps from video
http://moodlefairy.posterous.com/activity-locking-course-format-for-moodle-19. I am getting following errors when I click notifications:

Enabling the PHP setting display_errors is not recommended on production sites because some error messages may reveal sensitive information about your server.

The cron.php maintenance script has not been run for at least 24 hours.

Please register your site to remove this button

Can anyone please tell me how to solve this problem??? I am not able to install this feature on my localhost.

Hi there. Just a recap from other posts so others can help you -those settings are not important if you are running on local host and not online.
You have said in other posts that your Moodle is working ok and that you can select the Activity locking course format in course administration>settings.
Could you please clarify what exactly is NOT working? What happens when you select the activity locking course format and then you start building your course?

As Chardelle says in this forum http://moodle.org/mod/forum/discuss.php?d=128318.
that after copying activity_locking folder into moodle/blocks, by clicking Notification one shuld be able to install this feature. But I am unable to insatll it. But when I copy locking folder into moodle/format, i can see the activity_locking option while creating a course.

Glad you got it working

What you did is I suppose an equivalent of the switchitoffandswitchitonagain solution that seems to solve so many techie problems!

Hello Mary,

I have another problem now. I am not able to lock the courses as shown in the video. I mean.... three tasks are created and I set task-2 to be locked until task-1 is completeled, and task-3 to be locked until task-1 and 2 are completed. But it seems to be not being locked. When I login as a student I am able to access task-2 without completing task-1. Can you please tell me if I hav to add any code or make any changes to it.

Have you gone into tast 1 and set activity completion - for it to have to be completed?It is very difficult to help when your Moodle is not online really-what icons(boxes/locks etc) do you see next to your 3 activities as a brand new student to the course? If you create a new user, then enrol them in the course as a student and take a screenshot - could you do that?

Thanks for your reply. No I do not have an option that asks for completion of activity. But I can see the lock image next to the activity when I login as a student. I can send you a document that contains screenshots to ur email. i am not able to upload the document to the forum.

Thanks Divya. I got your screenshots. First of all, have you had a look at

shows how you can set a completion of activity requirement - which you should do for activity 1 so that they must complete task 1 before they are allowed to go to task 2.
In your email you seemed to be looking at the actual task itself for the completion requirement rather than clicking on the lock. Try this and see if it works.

well, again; this shouldn't really make any difference I know and I don't understand why it might, but DeWayne Demland had the same problem as you with his Moodle offline and as soon as he put it online the activity locking worked. Could you post a screenshot of the activity locking requirements for accessing quiz 1 and also quiz 2?

Dear Mary cooch,

Technically speaking i fail to understand the fact when people say they are able to make work AL code properly when they host it through internet and the same AL code with same moodle engine with dependencies running on their localhost dosent seem to work properly.

Divya muvvala as mary cooch mentioned , it would be easier for us to isolate the problem if you post some screen shots of what locks you have applied to those activities.

Hi Divya. I see from your screenshots that you want them to access quiz one only after they have accessed the forum but you have not set any activity completion in the forum.I suggest you click on the lock next to the forum and scroll down to activity completion -click on access forum and then try again. I suggest then you log of and then log in as student (ie, not using the log in as feature from admin) and test it out then. I have tried this and it works.

I have another question, when I create a new course there is a default New forum created automatically by Moodle. When I set lock to this and login as a student I get this screen( Note: will send u by email) I am not sure if this is correct way.

Every time you create a new course Moodle automatically creates a news forum. If you don't want it, you can either switch if off all your courses in Site admin>courses>course default settings or else you can go to the individual course settings in course admin, turn news items to 0 and then delete the news forum with the x on your course page. Note that students cannot post to a news forum; they can only read the news.

Divya - your latest screenshot showed the news forum with a message to students "no news has been posted yet" This is correct. The news forum is a general announcement forum for teachers to post news about the course. Students can only read and not reply. Test it out by logging in as admin or a teacher and then posting an announcement.

What is the first activity that your students must complete before they are allowed to access quiz 1? And on that first activity (which is obviously not the news forum) have you set the lock to make sure that activity is completed? If yes, I can only go back to the thought that somehow this is not working offline as it didn't for DeWayne - but that does not make sense...

Here how I created----

I selected Forum from the 'Add an activity' dropdown box. Then set the name of the forum and selected 'save changes' button. Similarly I selected quiz from 'Add an activity' dropdown box and set some questions (Note: i didnt change default settings for both activities)
I turned on editing ON and clicked locking image present beside Forum activity, ticked the box 'User must access this activity' and clicked saves changes button
Then clicked locking image beside Quiz-1 activity, ticked the box 'User must access this acitivity' for Forum and set the maximum marks for activity completion of Quiz-1 to 5. Selected Sava changes button
Similarly clicked locking image present beside Quiz-2 activity, ticked for Forum and set maximum marks for Quiz-1 and set maimum marks for activity completion for Quiz-2.

So from this, I hav first set to access the forum then quiz-1 and then quiz-2. But this is not happening so. I can access quiz-2 before completing quiz-1/ forum.

Dear Divya muvvala,

I dont see any flaw in the procedure that you have followed to put locks, This should work.

If you lock some activity or resource does locking icons appear for both admin and student ?

Are you sure that the AL CODE got installed properly , i would suggest you to turn debuging on to developers mode, and then do the same procedure once again to see whether you get any errors.

Dear Mary cooch

If i lock some activity or resource , i can access them i if i login as admin :O

it says "This activity is currently locked. You must complete the following prerequisites first: "

I know this shouldn be the case , posting it here to ask whether thats the way it is designed or i screwed up my system as i played with lot of core files :P

please ommit the above uploaded file , it didnt have proper error handling done in it,If you have debugging on to developers mode you will see ugly non userfriendly messages.

Heres the latest one in which all the errors are handled good enough for not only the above mentioned issue but for other issues as well which i had with AL CODE.

Hi Ravi,

Thanks for your reply. When I installed activityLocking everything showed me success and there were no warnings or errors. I can try as you said ... i mean to turn debugging on to developers site but I dont know how to do this. Can you please tell how I can go about it.

Did you try this plugin on your localhost or anyother server????

Dear Divya muvvala,

you didnt answer for the another question of mine.

If you lock some activity or resource does
1. locking icons appear for both admin and student ?
2. unlocking icons appear for admin/teacher ?

Yes Locking icons appear for both admin and student and unlocking icons appear for admin/teacher. And when I login as a student, access forum or other activity first a tick mark is shown.

I have a question, I was checking with my locklib.php file with your file which you have attached in the above forum. Does the code be affected due to spaces???

Regarding locklib.php

NO , spaces wont affect the code execution format unless and untill its breaking some parameters...

ex : $variable_sample is different from $variable _sample

And regarding the AL CODE execution on your machine,

I am left with no choice right now than to ask you this,

did you insert the three lines in your lib/moodlelib.php on about line 1975 under the function_require_login AFTER this code:

/// If the site is currently under maintenance, then print a message
if (!has_capability('moodle/site:config', $sysctx)) {
if (file_exists($CFG->dataroot.'/'.SITEID.'/maintenance.html')) {
print_maintenance_message();
exit;
}
}

pasted in the following code there ?

//Check to see if Activity Locking criteria have been met
require_once($CFG->dirroot.'/course/format/locking/locklib.php');
global $cm;
check_locks($cm);
