Unable to update to Joomdle 2.0.1 - XMLRPC error

Hi,

I've got Joomla 4.1.4 & Moodle 4.0.1. Both are configured to use REST and not XMLRPC. I have recently moved to PHP 8.0 and have run into some XMLRPC issues.

I was successfully able to upgrade Joomdle on my Moodle installation to 2.0.1. However, I am unable to update Joomdle on my Joomla installation. Whenever I try to update, I get "An error has occurred. 0 Call to undefined function xmlrpc_is_fault()".

I can downgrade my Joomdle on Moodle to 2.0.0 in the meantime, but does anyone have any ideas in the meantime as to how I might be able to get 2.0.1 onto Joomla with PHP 8.0? As best as I can tell, I shouldn't need XMLRPC to install Joomdle.

Thanks in advance for your help,
John

Hi.

So, you are getting this error when you try to install 2.0.1 on Joomla? I will investigate to see if I can find the error.

> As best as I can tell, I shouldn't need XMLRPC to install Joomdle.

Yes, that should be the case.

Yes, correct.

No issues updating Joomdle on Moodle from 2.0.0 to 2.0.1 on PHP 8.0

Can't update Joomdle on Joomla from 2.0.0 to 2.0.1 on PHP 8.0

I rolled PHP back to 7.4 and was able to update the Joomla Joomdle extension to 2.0.1 without issue, so it seems to be a PHP 8.0 and XMLRPC issue (based on the error message -> call to undefined function xmlrpc_is_fault(). I then rolled PHP back forward to 8.0 and all extensions work fine. So the problem is only limited to upgrading/installing.

Great, thanks for the info. I will check it out as soon as I can.

I have now uploaded v2.0.2 to fix the problem. Thank you very much for letting us know about it.

Thanks Antonio. Unfortunately I now am unable to update Joomdle Core in Joomla. I get the following error:
Your Moodle version does not support this Joomdle release.
Installed Moodle version: Array
Required Moodle version >= 2018120300
Extension Update: Custom install routine failure.

I currently have Joomdle 2.0.1 installed on Joomla 4.1.5 and Moodle 4.0.1+ (Build: 20220617) with PHP 8.0. This setup is working fine at the moment.

Any ideas as to why the 2.0.2 update can't read my Moodle version?

Thanks

Thanks for the bug report. I will release a new package to fix it and let you know.

The problem is an incorrect parameter in the function to get the moodle version...it's been there for some time, but it did not cause any issues until now, so I didn't notice.

As not many people are using PHP8 (the problem only happens with PHP8), I am going to wait some days before releasing a new package, in case something else comes up.

If you want to be able to update now, you can do a little change yourself.
File: moodle/auth/joomdle/helpers/externallib.php
Remove $search parameter from get_moodle_version function.
After that you should be able to update in Joomla.

Perfect. Thanks for your work on this Antonio. It's very much appreciated!

I am testing now to move to PHP8 with Joomla 4.1.5 and Moodle 4.0.2 and Joomdle 2.0.2. My Web service in Joomdle is set to XML-RPC.

Get the following error related to the current topic when switching to PHP8 on the server. After removing the $search parameter I still get the following errors when logging in as a user:

Call to undefined function xmlrpc_encode_request() with a list of the following errors:

1. () - components/com_joomdle/helpers/content.php:54
2. JoomdleHelperContent::get_request() - components/com_joomdle/helpers/content.php:104
3. JoomdleHelperContent::call_method_xmlrpc_curl() - components/com_joomdle/helpers/content.php:228
4. JoomdleHelperContent::call_method_xmlrpc() - components/com_joomdle/helpers/content.php:214
5. JoomdleHelperContent::call_method() - plugins/user/joomdlehooks/joomdlehooks.php:118
6. plgUserJoomdlehooks->do_login() - /plugins/user/joomdlehooks/joomdlehooks.php:95
7. plgUserJoomdlehooks->onUserLogin() - libraries/src/Plugin/CMSPlugin.php:285


However, when I refresh the page, does it display correctly? When I switch back to PHP7.4 I do not get this error and the switch to the requested landing page is correct.
