Convert word to image in cgi script

Hello!

I'm making a message board on cgi scripts.
And I want to make a simple function that converts some word in colons to specific image. For example instead of : picture: image picture.gif will appear. I think I need only some mark that means "any word". So if function finds any word in colons it replaces this word in colons with <IMG SRC="any word.gif">.

Can anybody help me?

looks like a little regex would do the trick:





This ain't perfect, but it should work OK. This will replace anything in a scalar surrounded by :: with the <img src=""> stuff.

So, "asdlkfsd sdflkfds:test:asfdlasdf; :test:" would become:

asdlkfsd sdflkfds<img src="test">asfdlasdf; <img src="test">

What it does: It looks for anything that's surrounded with : 's, with no whitespace before or in the string itself, and stores it in $2 for later.

Everything before $2 is stored in the first set of (), as $1, everything after $2 is stored in the third set of () as $3. The replacement then puts $1, then <img src="$2"> and finally $3 together, preserving the whole string. The /g modifier tells it do the match globally, as many times as it can and to ignore newlines.

Good luck!

Thank you very much! It's working!!!
