[RC] Hide BBcode

[marcovo]

@alhitary: actually this functionality is already provided by the [hidden] bbcode. I don't know whether it's a good idea to replicate this extension?

[masterbiz]

thanks

@parshavok: I will look into this.

Thank you

Hi,
You can unhide after thanking?
Not sending the answers!

I modified marcovo extension to hide content from anyone but a particular group of users named "Trusted Users". It can be easily modified to hide content from guests.

All you need to do is modify the listener.php file:

Code: Select all

I had no experience at creating extensions, so it would be great if someone could check the code (functions load_language_on_setup and check_user_is_trusted in particular)!

[uruguayito]

thanks. Works fine

One suggestion : perhaps the message: 'You need to reply to this topic before you can view the hidden message' could be in bold and red to make it better note

[Sepp71]

I am interested in the hide-function, too but I would like to have it implemented the official way for extensions (without having to change the code), because I have sworn to myself keep my source-code clean at 3.1 (I manage several boards on different URLs and want don't want to mix it all up as I did with 3.0.
So for the moment just watching this...

This actually is an extension.

[Sepp71]

Thanks for your reply!
Maybe I didn't understand it correctly: In the first post it says

The event above is not used any more in this extension. Instead, the following two edits will have to be done to make everything work correctly.

If this is still necessary it means a change to the original files (so not just adding and installing the extension), doesn't it?
Sepp

[parshakov]

Oh, sorry, you are right. I forgot.

[nero]

When will this be BETA?

This would be good for hiding content until someone posts

[marcovo]

With phpBB 3.1.3, not all necessary events were implemented in phpBB yet, so this extension needed an extra edit in the code. In phpBB 3.1.4, all necessary events are available, but this extension still has to adapt to it. I expect I will do this within a month from now.

[infinitiv]

Well, okay.
