OK, you can see two clear text versions of %id_link% and both of them get
replaced. So my next starting point was that big block of hex data in
between. Noticing there's a whole lot of double zeros in there it seems
likely that they're using 4 hex digits to encode a char.

Looking up the chars at http://www.lookuptables.com/ and writing the
hex chars out as four digit numbers gives me this string:

002500690064005f006c0069006e006b0025

That string appears twice within the datafield. I haven't tried it, but
I'd say give it a second str_replace and use that as the field to replace
(but remember to convert your ID in to 4-digit hex numbers.

Hope that helps.

Cheers,

Andy
