You can save to the Attributes column whatever you like: simple values or arrays. So there is no need to create a string from out of the arrays. Therefore you don't need $userIDs = "[".implode(',', $userIDs)."]";

I understand that $sender->RequestArgs[0] is the discussionid

Better would be to understand it and looking at Vanillas source code is very helpful here. You are inside of the discussionController...($sender) method. So $sender is a DiscussionController object. Look at the DiscussionController:
Why is that column name lower case? It really shouldn't be. What you see in there is a serialized string. It says it has an array with one element (I guess) and that the element is a string with 13 characters: DiscussionBan.
Something went wrong. Let me check my code and check if you have copied it the right way...
Oh no, the result of a:1:{s:13:"DiscussionBan";N;} is
array (
'DiscussionBan' => NULL,
);
So everything is correct except for the fact that $userIDs is null when you save it. There is a typo:
$userIDs = [];
foreach ($userArray as $name) {
$userModel = new UserModel();
$user = $userModel->getByUsername($name);
$userIDs[] = $user->UserID;
}
...
$discussionModel->saveToSerializedColumn(
'Attributes', // The column name
$sender->RequestArgs[0], // You should find out what this is
'DiscussionBan', // This serves as a internal key so that we can identify our d
$userIds
);

The last $userIDs has a lower case "d".
Aha!!! I see it. I think that was the result of intellisense on my editor because at one point I had it with the lower case d and I must have hit return when it had that highlighted. I hate "intelli"sense

I went looking how to do that in the discussion model but I didn't see how to do that. (In fact I didn't see the save to serialized either)

This time you have to follow back the DiscussionModels ancestors
If I do print_r($DiscussionModel) I can see all the data for that row in the discussion table.
Shouldn't $discussionAttributes = $DiscussionModel->Attributes; pull out just the attributes field from that?
instead I was able to get the value of the attributes field by using a query:
$DiscussionID = $sender->RequestArgs[0];
$Attributes = Gdn::sql()
->select('Attributes')
->from('Discussion')
->where('DiscussionID',$DiscussionID)
->get(); // Now it's a dataset!
//print_r($Attributes);
foreach ($Attributes->resultArray() as $attribute) {
// Do something to each user with 1 comment.
print_r($attribute);
}
Not sure this is the best method to use and then I need to figure out how to loop through the data
The result of discussionModel->getID is a discussion object. That's what you are looking for. So you would need to use it like that $Discussion = $DiscussionModel->getID($DiscussionID);. Afterwards you have a Discussion object that you holds the information you need.
If you look at the contents of the $discussion with print_r you would find everything you need.
Here is my class...Where I do not know how to get at the attributes data. While I have done a lot of PHP scripting I am new to object oriented PHP coding.

Alright, here is the plugin with a few changes:
1. added 'MobileFriendly' => true, to PluginInfo array so that your plugin would also be available on mobile browsers
2. I understood that you have a problem with the short array notation: only using [1,2,3] instead of array(1,2,3) isn't working for you. You should update your PHP version! I've deleted a comment block from base_discussionOptions_handler
3. Added docblock to base_discussionOptions_handler
4. Added some extra blank lines and removed trailing spaces here and there
5. New line 72 & 73: print discussion attributes
6. Commente the wrong $userIDs = "[".implode(',', $userIDs)."]";

Hmmm this is what was saved in the discussion table:
You can save to the Attributes column whatever you like: simple values or arrays. So there is no need to create a string from out of the arrays. Therefore you don't need
$userIDs = "[".implode(',', $userIDs)."]";But you only have guessed that
Better would be to understand it and looking at Vanillas source code is very helpful here. You are inside of the discussionController...($sender) method. So $sender is a DiscussionController object. Look at the DiscussionController:
https://github.com/vanilla/vanilla/blob/release/2.3/applications/vanilla/controllers/class.discussioncontroller.php#L14
It doesn't have a RequestArgs property. But it extends the VanillaController, so we can take a look there:
https://github.com/vanilla/vanilla/blob/release/2.3/applications/vanilla/controllers/class.vanillacontroller.php#L14
No RequestArgs here. But this controller extends the "base" controller: Gdn_Controller (base, because every controller extends that one)
And here in the base controller you will find a clean explanation for "RequestArgs":
https://github.com/vanilla/vanilla/blob/release/2.3/library/core/class.controller.php#L88-L97
Why is that column name lower case? It really shouldn't be. What you see in there is a serialized string. It says it has an array with one element (I guess) and that the element is a string with 13 characters: DiscussionBan.

Oh no, the result of
a:1:{s:13:"DiscussionBan";N;}isSo everything is correct except for the fact that $userIDs is null when you save it. There is a typo:

I got that from doing a print_r on it and saw the value.
INteresting on how to follow the controllers back.
Aha!!! I see it. I think that was the result of intellisense on my editor because at one point I had it with the lower case d and I must have hit return when it had that highlighted. I hate "intelli"sense
Ok now it is saving: a:1:{s:13:"DiscussionBan";s:7:"[16,19]";}
That looks right for the users that I selected in the form
Reading Vanillas source and investigating in there is the best way to become a plugin author!
I will be reviewing this entire thread for quite some time over and over and over again.
Ok so one of the first steps I need to do is to populate the text box if there already was people banned from the thread.
I went looking how to do that in the discussion model but I didn't see how to do that. (In fact I didn't see the save to serialized either)
Yes, you really should
What is it that you want to populate? A field in the database (class model) or a form field (class form)?
https://open.vanillaforums.com/discussion/comment/248317/#Comment_248317
This time you have to follow back the DiscussionModels ancestors

Yeah I did a print_r on $discussion and found that there were like 3 listing for attributes.
If a discussion has Attributes (not every discussion need to have that information) it is stored as an array.
Maybe it's time to post your complete code to do some cleaning on it and see what is working and what is missing
