How do I change words in post texts?

[Emeralda]

I tested it with editing an existing post and it was still turning the word into *****

Also, the full phrase I wanted was "I'm a little teapot" but there is that ' thingie.

Maybe try turning off the built-in censoring, it probably changes to *s before your code gets a chance to run.

If you're replacement has a ' then you can put a backslash in front of it, or else use double quotes around the string instead of single.

Oh, yeah, the auto censoring had to be turned off. But it all works now~

Also, the thing with excluding forums, I used it and it works, but if I'd want to add more than one forum, should I just add a comma after the ID?

[kh99]

You could do something like:

if (!in_array($forum['forumid'], array(1, 2, 3)) // exclude forums 1, 2, and 3
{
...
}

or if you'd rather list the forums to be included, remove the ! from in front of in_array.

Uhm, I have a sudden need to apply this for visitor messages and View Conversation (especially links). Which hooks to use for those?
