It's great , fantastic, I never could have made that myself...

If I understand correct, If I use [[wiki]blaa] it goes to the english version?

Holy crap, what was that?

I would have just used the 'e' modifier with preg_replace().

My PERL Regex aren't that good... At least I'm sure the replacement of _ isn't possible with a simple regular expression. How would you do that with your preg function?

By the way, Leo's solution with the preg_replace does work, but only if there is one link to replace. Try this:

code:

---

$input = "[[wiki:nl]RAM] and [[wiki:en]Does_this_work]";

---

Off course it should give 2 links, but it gives:

code:

---

<a href="http://nl.wikipedia.org/wiki/RAM] and [[wiki:en]Does_this_work">RAM] and [[wiki:en]Does_this_work</a>

---

My function does work there. It also works if you don't specify a language. So [[wiki]Test] is just replaced by http://www.wikipedia.org/wiki/Test

When the string is incorrect there might be an infinite loop by the way... So it could be better.

But how would you do it with preg_replace? I can learn from it too

code:

---

$string = preg_replace('/\[\[wiki(?:\:|)([a-zA-Z]+|)\]([a-zA-z0-9]+)\]/e', 'defL("$1","$2")',$string);

function defL($lang,$title){
if($lang=='')$lang='en';
return "<a href='http://$lang.wikipedia.org/wiki/$title'>$title</a>";
}

---

that works fine

code:

---

$string = preg_replace('/\[\[wiki(?:\:|)([a-zA-Z]+|)\]([a-zA-z0-9]+)\]/e', 'defL("$1","$2")',$string);

function defL($lang,$title){
if($lang=='')$lang='en';
return "<a href='http://$lang.wikipedia.org/wiki/$title'>" . str_replace("_", " ", $title) . "</a>";
}

---

That also replaces the _ to spaces. Ok I didn't knew something like this did exist, really interesting. This is the final one, and is the best option I think.

Maybe replace $lang='en' by $lang='www', so people are sended to the default language of wikipedia, and maybe to there own language if wikipedia introduces a language check...

code:

$string = preg_replace('/\[\[wiki(?:\:|)([a-zA-Z]+|)\]([a-zA-z0-9_]+)\]/e', 'defL("$1","$2")',$string);

function defL($lang,$title){
if($lang=='')$lang='en';
$title1 = str_replace("_", " ", $title);
return "<a href='http://$lang.wikipedia.org/wiki/$title'>$title1</a>";
}

looks neater   oh and i also added the _ to the regexp capture part.

Damn! I spent a while reading that yesterday and didn't see it... That's really time saving!

Found a little error, fixed it

Instead of using the parts defined in the tag it made a link like this:
<a href="$lang.wikipedia.org/wiki/$title">$title1</a>

That isn't an error is it? I'd rather prefer:

code:

---

return "<a href=\"http://" . $lang . ".wikipedia.org/wiki/" . $title . "\">" . $title1 . "</a>";

---

But thats just style..

WTf please tell me how it would return a link like that

my code

code:

---

$string = preg_replace('/\[\[wiki(?:\:|)([a-zA-Z]+|)\]([a-zA-z0-9_]+)\]/e', 'defL("$1","$2")',$string);


function defL($lang,$title){
if($lang=='')$lang='en';
$title1 = str_replace("_", " ", $title);
return "<a href='http://$lang.wikipedia.org/wiki/$title'>$title1</a>";
}

so im not getting how its an error...
