I am trying to implement a custom navigation block for my custom theme that only shows the links to contents in the particular section.

I have implemented a function to fetch relative data from database and echoed out the content from function in the layout.

function theme_activity_navigation()

{

    global $CFG, $COURSE, $DB, $USER;


    $id = optional_param('id', null, PARAM_INT);

    if (!$id) return null;


    $section_id = $DB->get_record('course_modules', array('id' => $id, 'course' => $COURSE->id), 'section', IGNORE_MISSING)->section;

    $section_sequence = explode(",", $DB->get_field("course_sections", "sequence", array("course" => $COURSE->id, "id" => $section_id)));

    $html = '';

    foreach ($section_sequence as $sequence) {

        $custom_class = '';

        if ($sequence == $id) $custom_class .= 'active';

        if (sajha_iscomplete_module($sequence)) $custom_class .= ' completed';

        $cm = get_coursemodule_from_id('', $sequence, 0, false, IGNORE_MISSING);

        $html .= "<li class='{$custom_class}'><a href='{$CFG->wwwroot}/mod/{$cm->modname}/view.php?id={$sequence}'>{$cm->name}</a></li>";

    }

    return $html;

}

I have used optional_param('id', null, PARAM_INT); to filter sections based content.

optional_param('id', null, PARAM_INT); will get '48' if I am visiting url 'moodlesite.com/mod/page/view.php?id=48'.

This works fine.



However the problem arises in quiz attempt page. Since I use optional_param('id', null, PARAM_INT); and moodle quiz attempt url looks something like 'moodlesite.com/mod/quiz/attempt.php?attempt=41' I can not fetch the course activity id data to do a database hit.

and the function theme_activity_navigation() return null.


Is there a better way to get navigation lists per section or maybe the above function can be modified to fix the quiz issue?

Hi, 

Unfortunatly I am limited with my knowledge of PHP and such, however, I would not consider this question a Theme related issue although it may in part be related to a custom theme by nature of the changes you are attempting to make.

With this in mind I'm very tempted to move this to the Developers Forum if no one here replies in depth within the next 24hrs.

I am really sorry I can't help...but I have a feeling there is an easier way to achieve what you want!

Cheers

Mary

Probably get an instance of the 'course' renderer and look at what methods it supplies.

Dear Gareth,

can you elaborate a little more? Do you mean I should look into the moodle's  course's renderer.php and see what the functions there provide?

This is the course/format/topics/renderer.php from the Moodle 2.9 stable branch.

Definitely don't look at random URL parameters, and expect it to mean anything consistently on different Moodle pages.

Information about the current page is stored in the Moodle page object. In a block you can access that as $this->page.

$this->page->cm->id is probably what you want, or $this->page->cm->section, etc.

The page class is defined in lib/pagelib.php.

Dear Tim,

    Thank you for your response. I am new to moodle and programming in general. Your redirection is the right path for me and has worked absolutely right for this particular issue. 


I have now made my function parameterized function theme_activity_navigation($id){...}  and I am retrieving the page id from a page object context as $id =$this->page->cm->id.
