Logstore xAPI
Maintained by
David Pesce
Logstore xAPI captures Moodle activity and sends it to a Learning Record Store (LRS) as xAPI (Tin Can) statements. Once configured, events like course views, quiz attempts, assignment submissions, and forum posts are automatically recorded in your LRS — no changes to your courses required.

I'am trying to debug the source code of Logstore xAPI, in order to understand how this code works to be able to adapt it to my use case. For this, I wonder what is the entry point of this code? Thank you in advance for your reply
Notice: Undefined offset: 0 in D:\WWP\wamp\www\NGT2\lms\admin\tool\log\store\xapi\classes\log\store.php on line 158
Might changing line 157 of store.php to this line of code remove the notice while not causing any issues with your plugin?
if (is_numeric($key) && isset($xapievents[$key]['context']['extensions'][Event::CONTEXT_EXT_KEY]['id'])) {
But I add this remark to those who work behind a proxy server:
If you are using the Tincanlaunch Mod and you are behind a proxy server, consider changing the proxy configuration in
admin / tool / log / store / xapi / vendor / rusticisoftware / tincan / src / RemoteLRS.php
by removing the automatic configuration:
35 // protected $ proxy;
Add :
87 // this is here for some proxy handling
88 'proxy' => '192.168.xxx.xxx:8080',
and disable:
/ *
106 if (isset ($ this-> proxy)) {
107 $ http ['proxy'] = $ this-> proxy;
}
* /
In this way, xAPI will also work for Tincan content
All versions of the plugin after this date do not work: so DONOT try to install them, in fact best would be for them to be taken down before they cause others a whole load of headaches.
Thanks for this reply. As David explained, after populated the records into ‘mdl_logstore_xapi_log", I executed the scheduled task . However there is an issue in new plugin version (2017061100). I can successfully send xapi statements into Learning Locker, but records didn’t delete from the ‘mdl_logstore_xapi_log’. I found this issue here in store.php
$xapiEvents = $xapiController->createEvents($translatorEventsBatch);
foreach(array_keys($xapiEvents) as $key) {
if (is_numeric($key)) {
$sentEvents[$xapiEvents[$key]['context']['extensions'][$translatorEventReadReturn[0]['context_ext_key']]['id']] = $xapiEvents['last_action_result'];
}
}
$xapiEvents variable get response like this,
Array(
[statements] => Array()
[response] => TinCan\LRSResponse Object(
[success] => 1
[content] => Array()
)
Therefore is_numeric doesn’t work as array keys are ‘statements’ and ‘response’. Further there is no attribute called 'last_action_result' here. Can you please explain this to me? Thanks for your time.
