Hi there!
Let me tell you that I think that LTI is a wonderfull concept.
However:
I tried to play around with LTI.
I inserted "ads" into the ads.ads in my MySQL-Database, after creating it with the
given script.
there was no output on behalf of ads.php after calling it through php-simple/lms.php.
Although the Documentation stated otherwise.
So I though well, I might as well copy ads.php to another file and start working on it.

After copying the entire Code into another file, located in the same folder I get an error :Could not establish context: Could not find context in session " .

So I have 2 questions:
1) why isn't ads.php showing any results,although results are present and users are created
2)Why is the code in ads.php giving an error when copied to another file


I assume the second point is due to the name being different, so the file name - postfix identifies the DB-name/Table name(?),so:
where do I find Documentation which talks about stuff like this.

Sincerely

olive

Olive thanks for the question. I assume that you went all the way through the setup instructions in:

http://ims-dev.googlecode.com/...mple/adlist/index.htm

There is also a presentation about how this all works at:

http://www.imsglobal.org/devel...05-20-blti-php-02.pdf

In terms of no ad output after you call it from lms.php, all you should get at the beginning is a "Create new Ad" link.

I would go through ads.php, adding die("Message"); to step through and see how far it gets.

You may be dealing with something like PHP5 versus PHP4 and have errors set to be completely silent.

Dear Chuk,
I am new to LTI and also facing the same problem could you please update your code.I follow the
the all of your instruction but not able to configure

Hi there!
The problem that nothing is shown, is a problem with Firefox 3.6.18 under Ubuntu Linux.
Chrome has no problems though, neither have FF4.x versions for Windows.
The rest was a PHP4 vs PHP5 issue,and sessions are handled differently.
I had to change the order in which session() and header() are called.

I agree with foryougautam.
A port to PHP5.x and mysqli would be outstanding.
None the less, the class-structure is very good, just writing a wrapper for webapps, not ment to be for LTI, using greate parts of your code.
Once again thanks for the Code.

@foryougautam:

Following Code is the the original code altered by me.
public $MYCONNECTION; in class BLTI is never set.
I changed that.
Since the class is created every time we have a call to the script it works perfectly.
Have fun with my adaption,they are minor though, only a couple of lines ,and I am not very happy with them.


blti.php
(line 102,103 btw it seems like it always ends up entering this if-clause)
(I patched it like this so that I may have a basis to work with,
You might want to recheck it though in case you want to use it on a productive system)

-----------------------
Since we are using mysql_func()-calls we need a connection, so we make sure we use the right one, and use $context->MYCONNECTION.
(I'm pretty sure we do not need that since PHP-executes every request as a process but we want to make sure, and I have no clue how FastPHP behaves in such a situation,so just in case)

Dear OLIVE

Thanks for your quick response.
I have implemented LTI provider in my product with the help of your code. I am using Basic LTI tool consumer in Moodle2.x & found that everytime i want to expose a resource from a LTI Tool producer I need to add it in Basic LTI administration panel with a shared key pair. This resource can then be utilised from within the interface of Moodle in an embedded iframe. When I started using LTI I was of the idea that we register repositories and then use assets / resources from these repositories in our LTI tool consumer. However now I find a shift here. We need add resources with the relevant key/pairs in the Basic LTI Administration panel in Moodle. This is very limiting by the fact that we have a huge number of assets(videos, resources, documents, experiences) that needs to be exposed.

My question is, is there a way to make only one repository per producer and still identify all of the resources in that repository with different contexts in different areas / courses? Following what is happening currently we get a huge list in the "Add an activity" dropdown which doesn't suit the user experience and is also much of a constraint. If I have not understood correctly kindly guide me how this can be done if this can be done.

Awaiting your response.

Rgds,

Gautam Bishwas

Dear foryougautam,

IMHO , defining a repository or defining a ressource should look all the same to Moodle.
Just add a script managing the repository to Moodle, identify it using LTI and provide additional parameters, if you want, or allow browsing through the repository.
Just keep in mind that you will need to add the LTI-part every time you make a call to the serversidescripts.

You can further protect the resources by additional scripts or temporary files/directories.

sincerly

Olive
