function discussthis_create_discussion_form_submit in Discuss This! 7.2

Same name and namespace in other branches

1. 7 discussthis.discussion.inc \discussthis_create_discussion_form_submit()

Save the new comment.

This function creates a new forum topic if this is the first comment on this node. Otherwise, it just adds the comment to the existing forum.

@todo We've got a problem here, if the administrator wants to moderate these comments, then we should not create the forum node. This is a similar problem to the one we see in creating the forum node before the comment is even posted to us.

I guess that the biggest problem is that a comment, to exist, needs to be attached to a node.

I see two potential solutions:

1) we handle our own comments

2) we create the comment on the node being discussed and move it later to the forum

Parameters

$form The form info:

$form_state The current state of the form, including the values:

1 string reference to 'discussthis_create_discussion_form_submit'
