Question

I’m working on something for phpBB3 of my own, I’m trying to convert those smiles back to the oringinal smiley state, e.g.

:)  :(  :O  :P

Since the HTML of a smiley contains this:

/<img src=".*" alt="(.*)" title=".*">/gi

Replaced to:

$1

However, when I have multiple smileys, it just show the last smiley, e.g. if it was like this:

alt text http://uimgz.com/i/R2e3H8g5D8.png

It turns into this:

:twisted:

Which is the last smiley on the right, why hasn’t it replaced and returned all of the smiley states which it should return like this:

:) :o :twisted:

The Regex seems fine, but I don’t what seems to be the problem, all of the regex go through a replacement loop using a for() loop so that’s not the problem.

Multiple smileys HTML:

<img src="./images/smilies/icon_e_smile.gif" alt=":)" title="Smile" /> <img src="./images/smilies/icon_e_surprised.gif" alt=":o" title="Surprised" /> <img src="./images/smilies/icon_twisted.gif" alt=":twisted:" title="Twisted Evil" />

Change the regex to this and try again:

/<img src="[^"]*" alt="([^"]+)" title="[^"]*">/gi

The regex engine is usually greedy. It will try to match the longest text matching something. In your case i it matched all three links as one. What i did here was to limit the content inside the src attribute to not contain ” so it will not match all the way to the third src.
It treated this as a src attribute ./images/smilies/icon_e_smile.gif" alt=":)" title="Smile" /> <img src="./images/smilies/icon_e_surprised.gif" alt=":o" title="Surprised" /> <img src="./images/smilies/icon_twisted.gif
