Navigation buttons (for Moodle 1.9 / 2.0+)
This block adds customisable navigation buttons (first/previous/next/etc.) to the bottom of each activity/resource page in a course.

It is based on an idea from Penny Mondani: http://pennymondani.com
Thanks also to the US company that sponsored the development, who wish to remain anonymous.

Installation:

2. On your server, in the 'blocks' folder, create a subfolder called 'navbuttons'
3. Upload all the files inside the 'davosmith-moodle-navbuttons-???????' folder to this new 'navbuttons' folder on your server.
5. You need to make a small change to one Moodle core file to make this work (the change is different between Moodle 1.9 & Moodle 2.0 - see the included README.txt for details).
7. Customise the button appearance by clicking on 'Edit the Navigation Button settings' in the newly created block.
8. Check the message at the bottom of the screen (under the 'Save changes' button) - it should read "Navbuttons self-test: required core modifications have been completed successfully". If not, then go back to step 5 above and check carefully.

Note: The block is only visible to users who are able to edit courses modules. Deleting the block will remove the navigation buttons (they can also be disabled through the settings).

For a quick demo, there is a screencast available here:

Sheila, I guess you could insert the core hack to output the buttons into a different place in the code to output them to a different place on the page. Probably somewhere in the header() function, but I couldn't tell you exactly where.

Cool. Thanks. I'll give that a go.

I haven't found where to put the code yet. I tried a few places but it didn't render. It's late here now, so I'll try again tomorrow. In the meantime, if anyone can think of how I can get the buttons in the top navbar area (in course pages only) I'd be happy for your input ...

Hi Davo, I want to delete the plugin but when I do that (remove the navbutton map or remove it from the plugin page within moodle) i get this error:

Warning: require_once(/.../moodledir/blocks/navbuttons/footer.php): failed to open stream: No such file or directory in /.../moodledir/lib/outputrenderers.php on line 1283

Fatal error: require_once(): Failed opening required '/.../moodledir/blocks/navbuttons/footer.php' (include_path='/.../moodledir/lib/pear:.:/usr/local/php70/pear') in /.../moodledir/lib/outputrenderers.php on line 1283

How can I safely uninstall the navigation buttons?

thanks,
jose

Jose - just reverse the changes to outputrenderers.php that you made whilst installing the plugin (for reference, the instructions are here: https://github.com/davosmith/moodle-navbuttons/blob/master/README.txt#L35 )

that's it, I forgot I changed that file. Works now, thanks.

Hi Davo,

I modified the outputrenders.php file as instructed in the readme file but mine still does not work. I am running Moodle 3.3 with the Adaptable 1.5.3 theme.

The output says Navbutton self-test: The line "$output = draw_navbuttons().$this->container_end_all(true);" has not been correctly added to outputrenderers.php - see README.txt for further instructions

This is what I put in the php file:

public function footer() {
global $CFG,$DB, $PAGE; // Give plugins an opportunity to touch the page before JS is finalized.$pluginswithfunction = get_plugins_with_function('before_footer', 'lib.php');
foreach ($pluginswithfunction as$plugins) {
foreach ($plugins as$function) {
$function(); } } require_once ($CFG->dirroot.'/blocks/navbuttons/footer.php');
$output = draw_navbuttons().$this->container_end_all(true); {
// Change this line to enable the navigation buttons
}

$footer =$this->opencontainers->pop('header/footer');

Please switch to one of the standard themes (boost or clean) and see if it works. If it does, then to get it working with essential, you'll need to find where that theme overrides the 'footer()' function and add the core change there instead.

Sidenote. If you're using the essential theme, the line of code you need is in: public_html/theme/essential/classes/output/core_renderer.php

Hi Davo, I think there's an error in the latest zip folder. For the plugin version 3.4+ (Build: 2017100900) (2018042100), when I click the green download link, the zip folder that I download is completely empty.

Thanks Stewart - it's a problem with the github import not working properly as the plugin has been moved into the 'other' category, rather than the 'blocks' category (which breaks a lot of features of the plugins DB). Unfortunately, the plugin still needs a tiny core (or theme) modification to work, so it doesn't get to go anywhere else ...

Hi Davo!
I have a question about the plugin. When I click on Navigation Button settings, I see this message: Navbutton self-test: The line "$output = draw_navbuttons().$this->container_end_all(true);" has not been correctly added to outputrenderers.php - see README.txt for further instructions.

Can you helpme to fix this? I really want to use your plugin.

Thanks!

Hi Angela,

Have you read through the README.txt file included with this plugin (as it suggests in the error message)? If so, is there a particular bit of the instructions that you are struggling with?

A note for users using Adaptable theme, The line "$output =$this->container_end_all(true);" is located in :
