Well, the scripts are quite complex and tailored to specific schemes so I don't think you'll find them useful as they are. I bluffed a little bit where I said above that the link opens the grade page so that I update the student's grade and feedback. The link actually opens the grade page enters the grade and structured feedback and closes the grade page, by one click. So it probably does more than you need. But I can tell you how you can create the link and we can continue the exchange until you get it to work.
The idea is simple (as always). For each student you need the Moodle user id. You can find it in the user's name which you get by adding the built-in ##user## tag. When added it shows the user name linked to the user profile. The href of the a tag contains the moodle user id:
<a href="http://moodle.org/user/view.php?id=51600&course=5">James Scully</a>
So if you don't have it already in each record in the database, you need to add it. Then you can extract the id in the following way. Suppose it is in cell 0 of the table row:
Once you obtain this uid you can construct the url of the grade page of that student:
Where 101 is the assignment id which you can obtain after you create the assignment.
So for each entry in the list view retrieve the user id, create the url to the grade page of the designated assignment and assign that url to the href of the designated a tag in that row or as a parameter in window.open(...) in that a tag if you want a popup.
See if you can make it work and let me know if you need further assistance.
