Hi,

I'm looking for a snippet which permit to get a random number inside a range.
Example to get a random number between 12 and 24: [[RandomNumber?&begin=`12` &end=`24`]]

I'm newbie with snippet development, and a little help could be usefull

If you create a snippet with that name RandomNumber and those two parameters the code would look like:

<?php

if((isset($begin) && isset($end)) && $end >= $begin){
  return rand($begin, $end);
}
return 0; // Return zero for false could return something else if desired

Just copy past that into the snippet and also make sure you call the snippet uncached:

[[!RandomNumber?&begin=`12` &end=`24`]]
