[code] BBCode

[Tazerenix]

Hey.

My problem is, im working on a bbcode class. I've got everything working, all the normal BBCodes, quotes even. The only problem i'm having is with the code BBCode.

I can get it to partially work but if someone puts a /code as part of the inside of a code section it ends the section. I'm not entirely sure how to stop it. Anyone know how?

[JAY6390]

Can you show an example of what you have that works and what you have that doesn't

Thats my current BBCode Class

(please don't pwn me for it being shit, i'm not the greatest at php).

 

My current method, preparses the data (before entering a database). And then, when the bbcode is parsed, it just replaces each code it finds. I have also tried a regexp method but it didnt really go to well. (i actually deleted that, sorry).

 

Any ideas?[/code]

[trq]

but if someone puts a /code as part of the inside of a code section it ends the section

 

What exactly would you expect to happen? Any parser still needs the correct syntax given to it.

[JAY6390]

Very true. You can't parse a [/code] within a

block. Those are the basic principles the parser works on

[Tazerenix]

strange, phpbb's one seems to do it

[JAY6390]

You can put [/code] within a

block and it doesn't cut off straight away?

[Tazerenix]

mhmm, http://eobots-online.info/viewtopic.php?f=2&t=42&sid=08e6189e70443c0ddd330e96e2929412

[trq]

Your point?

 

phpBB likely allows

blocks to appear raw when there is no data within them. I still fail to see the logic in your question / problem. What exactly would you expect your parser to do when it sees a closing [/code] tag? I would expect it to close the code block.

[Tazerenix]

yea yea, i guess. XD. Well thanks for that. Now i can continue working without feeling dumb for it doing that lol

[ChristianeGuise]

sorry to intrude I just would like to know if you received my message and if you could help me you seem so good at PHP

Thanks in advance

who? i don't think i got any messages lately
