[SOLVED] Safetly Letting users use tags

[cooldude832]

I have a field on my profile system that allows a users to put in a paragraph about themselves.  I want to allow some very basic styling here (like returns, bold, color etc) is there a way I can add BB tags to this easily or some other method (I"ve never used BB tags before so if someone could point me in the right direction that be great).

Heres a bbcode2html,

as this board uses BBcode i have added @ signs to stop the parsing, your need to remove all of them..

I don't think it will parse the BBcode between [.code][./code] tags. So no need to worry about that in the future

 

Just to test...

got a feeling that the code and quote will mess it up...

 

EDIT: Holy Hell, remove @ from quote and code

Do you have the include 'bb2html.php' ??

[MadTechie]

that is the file.. just add the function "bb2html" to your project (or add it to a file and include it) then use as anyother function..

[cooldude832]

so should I striptags then apply bb2html to be safe, as I do'nt want stray divs to show up and mess up output

[cooldude832]

also do you have a reverse of this so that I can get it unbbed, I could store it unbbed in the database, but I prefer not to as this is a fairly large field

[cooldude832]

The color field doesn't seem to be working?

[cooldude832]

Never mind I solved it I needed to fix the slashes on it.  Gotta love MQ.  Anyway thanks a lot for that, I didn't realize that was how BB  code worked.
