I've provided the short solution in the package available to Download now.

The solution consists of 3 steps:

1) Copy YouTube image button
2) Modify bb_codes.php functions
3) Paste the code for the button in the post form template

Report here if something is wrong... it works on my side.

OMG trying right now...

OMG trying right now...
Does it work as you expected? :)

hmm, i cant get it to work. can i have instructions on how to paste the code? i dont understand anything in the bbcodes file. it bb code but it doesn't embed the video.

can i have instructions on how to paste the code?
highlight the text from , copy, and paste.. check youtube_codes.txt for instructions..

i pasted it in the bbcodes file, but i need details on where to paste which parts and if there's anything else i need to change, etc.

Well, I don't know what's difficult there.

Instruction already says:

edit /forum_folder/bb_codes.php and modify the functions (paste before $msg=preg_replace...)

Can you locate the string beginning with $msg=preg_replace ...?

I don't know how to say it easier.

well, i pasted it before that and it resulted in an error, where my forum page wouldnt load. i'll post my bbcode so you can see how it looks, maybe there's an inconsistency.

is something wrong with my bbcodes?

Anonymous
Yes, I think you've misunderstood. You have to put the encode function part into the encode function part and the decode function part into the decode function part, like so:

I think this is how it's supposed to be done but I haven't tried it myself so try it and see if it works.

i did it like you said, and it still didn't work. hmm

lime, is it workin on your side?

Hi Paul,

I just tried it to see if it works but it doesn't. The button works so that when you click on it the javascript popup asks for the youtube link.

When I tried it with this youtube link:
http://www.youtube.com/watch?v=QmroaYVD_so

the forum post showed this:
[youtube=http://www.youtube.com/watch?v=QmroaYVD_s o]

Notice the space between the s and o? That shows up every time.

Hope this helps you to troubleshoot.

Lime

Sorry, I thought only about URLs like //www.youtube.com/v/r-DomnRg72Q... so as if they would contain only letters, digits and slashes. So we need to extend the regular expression. I've fixed my code for bb_codes.php, please check out now.

Cool movie, by the way :-) I usually eat pets like this.

Joke :-)

hmm it works with the last youtube url you posted

"youtube.com/v/r-DomnRg72Q"

but not with some others.

where has the code been changed?
