Record ID Passed in Custom Link/Button

For some reason, whenever I use a record ID within a custom link or button, Salesforce is passing in the 15-character ID instead of the 18-character ID. In the past, I have coded around this on my own (using case-sensitive comparisons and substrings) but I'm now running into an issue where it's not possible to use these tricks.

Why is SF only passing the 15-character ID and how do I make it use the 18-character ID?

Thanks,
Mike

in javascript, so you can put this into an scontrol, then the scontrol will fixup the ID and display it in a field ( by putting the scontrol on the campaign page.)

 

 

Code:
function normaliseSforceID( id) { // fluff up a 15 char id to return an 18 char id
 if (id == null) return id;
 id = id.replace(/\"/g, ''); // scrub quotes from this id
 if (id.length != 15) {
  //print('well, id is not 15, bye' + id + ' ' + id.length);
  return null;
 }
 var suffix = "";
 for (var i = 0; i < 3; i++) {
  var flags = 0;
  for (var j = 0; j < 5; j++) {
   var c = id.charAt(i * 5 + j);
   if (c >= 'A' && c <= 'Z') {
    flags += 1 << j;
   }
  }
  if (flags <= 25) {
   suffix += "ABCDEFGHIJKLMNOPQRSTUVWXYZ".charAt(flags);
  } else {
   suffix += "012345".charAt(flags-26);
  }
 }
 return id + suffix;
}

Why do you need the 18-char ID?  The 15-char and 18-char IDs are equivalent and should be interchangeable.

In most cases this is true. However, I am using DbAmp to query data through a SQL Linked server and it doesn't work correctly unless you substring the ID and change the coallation in order to force a case-sensitive query. I am currently working on a new query in which the workaround doesn't work very well and would prefer to just get the 18-character ID so no workaround is needed.

Well, there is an algorithm to convert a 15-char ID to an 18-char ID.  This article describes it well.  The code example given there is in PHP.

This discussion board post gives some Javascript sample code for performing this conversion.
