Integrating Liferay in Moodle

[antz s franz, modificado 15 Anos atrás.]

Hi,

Can you please let me know how to integrate Liferay with Moodle. I need the existing Moodle users to use the Liferay by Single Sign On method. Can you please let me know the procedure for this.

Thanks,
Antony

We haven't done this yet but we are heading that direction. Our plan is to CAS as our single sign on solution. There are instructions on the Moodle site for casifying Moodle and Liferay has CAS support built in out of the box.

With both apps casified you should be able to switch back and forth easily.

Also there is a uportal portlet http://sourcesup.cru.fr/projects/cmoodle/ that shows the status of moodle courses that I'm hoping we will be able to utilize in Liferay.

Thank You for your valuable comments Andrew.! I will try with the CAS method and see how this can be done. Happy to know about your plan on this. Great.!

We have successfully done this by modifying the standard iframe portlet to 'pass the individual users information to moodle (or any other webapp). instead of just passing the static user information that the stock portlet can pass.

Once this is done in the iframe configuration enter the url that handles moodles login script like normal ( ..moodlepath../login/index.php) and the feild names that the uservalues should be assoicated with when passed (username and password in my moodle installation) and post as the method and form as the type for moodle.

I did this by modifying the code like below (feel free to use or modify if it is helpful), it has been awhile since i made the changes so I have included the entire files as I do not remember exactly which lines I changed at the moment.

all files are from the iframe portlet.

WOW thats Great Brian.! Nice way of achieving the integration. Thanks a lot for sharing your script. I will try to make this and see.

[Robin S., modificado 15 Anos atrás.]

Hi guys,

has anybody used this integration in 5.2? I tried it, but got a lot of Exceptions and Errormessages.
All I did was, copy paste the code for the 4 jsp files.
Anybody got this running in 5.2?

Thanks in advance

[Robin S., modificado 15 Anos atrás.]

Oh my god

Sorry to bother you guys. Look at view.jsp line 2, there's a unnecessary <% . After I removed this tag, everything works.

Thanks for code btw.

regards

OK, I promise this is my last post in here

Again, this was a simple mistake.

You need to append the [ i ] to the hiddenVariablesArray. So just replace hiddenVariablesArray with hiddenVariablesArray[ i ], where i is the counter of the loop.
