You are using wp_get_current_user and try to get
the user_id as
'user_id' => $current_user->user_id

But the wordpress api should be $current_user->ID
http://codex.wordpress.org/Function_Reference/wp_get_current_user

return array(
'user_id' => $current_user->ID,
'lis_person_contact_email_primary' => $current_user->user_email,
'lis_person_name_given' => $current_user->user_firstname,
'lis_person_name_family' => $current_user->user_lastname,
);

And I think the lti_launch_func only will be executed if there are a user logged in

Bests regards

In the shortcode, adding a configuration_url pointing to a waxlrs XML returns an error.

[lti-launch consumer_key=yourconsumerkey secret_key=yoursecretkey display=iframe
configuration_url=https://uomedtest.waxlrs.com/lti?u=https://uomedtest.waxlrs.com/embed/mostpopular
resource_link_id=testcourseplacement1]

This problem isn't so much with the wordpress-lti-consumer code, though. The problem seems to be that waxlrs returns a 404 Not Found if the Accept: application/xml HTTP header is being sent.

This gist isolates just the part of the code making the file_get_contents call to the waxlrs, reproducing the problem:

This gist, however, has the Accept: application/xml removed, which works.

When using the iframe shortcode in the output of an admin-side dashboard widget, the iframe is created but nothing is displayed inside the iframe.

It looks like the launch.js script isn't referenced on the admin-side, which is needed for the form (preceding the iframe) to have its parameters posted to the iframe.

Here's some code to create an admin-side dashboard widget (OAuth keys removed):

Documentation on creating dashboard widgets:
http://codex.wordpress.org/Dashboard_Widgets_API

It was reported that OAuth signature verification failed when launching http://ltiapps.net/test/tp.php . There might be an issue with signature verification when the outputted form fields aren't ordered properly.

This might just be a documentation thing, or possibly it could be detected, or something. They don't work properly with newlines present in the editor (even in plain text mode) because br tags get inserted.

Re #19 and cfd758d

The lti_version must be either "LTI-1p0" or "LTI-2p0", regardless of the sub-version.

See
