Actually grabbing all regular expressions matches

function MyTriggerFunctions($name,$line) {
	$pattern=$world->gettriggerinfo($name,1); // grab the regular expressions pattern of the trigger
	ereg($pattern,$line,$wildcards); // dumps all the actual wildcards results into the variable $wildcards

	$world->Note(print_r($wildcards,true)); // this just displays that $wildcards array
}

There's my workaround for this, just in case someone wants to do some weird stuff with regular expressions and actually grab the results. ;)

Another benefit of this method is it does not limit you to ten regular expressions wildcards--you can have as many as you like, with any language!

I hope someone finds use for this, and I apologize if this subject is already covered in some way.

I'm not sure what you mean by this, as it works perfectly:



<triggers>

  <trigger

   enabled="y"

   match="^You see exits leading (north|northeast|east|southeast|south|southwest|west|northwest|up|down|in|out) and (north|northeast|east|southeast|south|southwest|west|northwest|up|down|in|out).$"

   regexp="y"

   send_to="2"

   sequence="100"

  >

  <send>%%1 = %1

%%2 = %2</send>

  </trigger>

</triggers>

If I try that I get something like this:



%1 = north

%2 = east

Also, the standard regular expressions can have up to 999 wildcards, you can access them in various ways, here is one:

Also you can refer to wildcards larger than 9 in the "send" box like this:

%<45>

Well this is odd, then, if it works for everyone else.

I did notice that it does not work for PHPScript as is, WHEN I use the built-in GUI to edit triggers. :(

It might work for everything else, however.

Thanks!

It would be helpful if you posted the entire trigger, see this post for how to do that:

Perhaps your problem is the way you accessed the wildcards.
