Allow post author to block user from adding a comment WordPress

Reigel Gallarde comments:

can you give me a sample scenario?

I can help you with this..

pjeaje comments:

This is very different.
1. The user is blocked from the front end hence why I asked for a check box on the comment form
2 . the user must be registered so that the comment meta can detect when that user is trying to post a comment.

Reigel Gallarde comments:

hi, can you try adding these codes in your functions.php and see if that's what you wanted...

The post author can't block the user, only admin.

Each post author must have the ability to block the comment user per post

I updated the code...

this will make post author and any admin able to block users from commenting... if you don't want any admin to interfere, you can remove current_user_can('moderate_comments') || at the top.... and that will make only post author able to block users..

Thanks, if I can push my luck here...

1. admins can never be blocked by a user (a post author can block the admin comment)
2. a short message appears if a user has been block on the post. ("You have been blocked - You can not leave a comment on this post")
3. classes for checkbox and submit button for css styling by me.

whoops
1. admins can never be blocked by a user (a post author can *NEVER block the admin comment)

pjeaje comments:

At the moment... the admin can be blocked

pjeaje comments:

BUG: It seems that if a user is blocked it hides the comment form from all users on all posts. including the admin.

code updated.

for the bug, you can comment out line 7 and line 9 to see if the checkbox is checked for all users. checkboxes must be uncheck for admin and post author. You might have checked it on my first code test.
Or, try other post and see if the same bug happen.

class of submit is submit_blk_user_comments and blk_user_comments checkbox. I also made submit button to only appear if you clicked the checkbox at least once .

Thanks so much, your help has been brilliant.

pjeaje comments:

bug? the blocking only works if the users parent comment if un/checked, if the child comments are un/checked then it doesn't work.

This bug seems to be only on my phone?? let me check further

pjeaje comments:

OK... if it works ok but there's a little 'thing' to consider when testing it. You need to completely reload the page, not just refresh it, if that makes sense? otherwise the changes are not seen.

By "reload" I mean put your cursor on the address url in your browser and hit enter, whereas refresh is just hitting the round recycle icon on your browser. :)
