Hide Content - Require Feedback

[Jordan F.]

Hi all,

I'm new to coding MyBB plugins and have formed an addon which hides content when using the following BBCode:

[hide]Hidden content here...[/hide]

What does it do?
We have 2 settings in the admin control panel:

• Ignore usergroups
  
• Minimum posts 
  

When a user uses the above BBCode:

Guests will see the following message:

Please login or register to view hidden content.

A user who doesn't meet the required minimum posts will see:

Please make 5 posts to view hidden content.

A user who does meet the required minimum posts but has not replied to the topic will see:

Please reply to this topic to view hidden content.

An admin (and other ignored usergroups) would see the hidden content no matter what.

Here's my code:

Any feedback?
