[Templates] interpolate tt vars

[Corey Saltiel]

I'm trying to do something like this:


In a perl script/controller:

<snip>
$tt_vars->{'shnarf'}     = 'HELLO';
$tt_vars->{'params'}   = 'foo=bar&blah=[%shnarf%]';
$tt_vars->{'controller'} = 'snafu.pl';


Then in a tt:

<a href="[%controller%]?[%params%]">


Hoping to get:

http://snafu.pl?foo=bar&blah=HELLO


But instead I get:

http:://snafu.pl?foo=bar&blah=[%25shnarf%25]

The same happens ( for whetever reasons ), when I try:

$tt_vars->{'params'}   = 'foo=bar&blah=[&#37;shnarf&#37;]';


HOWEVER... when I do:

$tt_vars->{'params'}   = 'foo=bar&blah=[&#60;shnarf&#60;]';


I get:

http:://snafu.pl?foo=bar&blah=[<shnarf<] 

... as I would expect.


Any ideas why the percentage escape ( &#37; ) isn't working the way the other 
escapes do?

But more importantly - how do I get the behavior I'm looking for?
( i.e.  "http://snafu.pl?foo=bar&blah=HELLO"; )

I'm doing this to make a particular template more reusable in a variety of 
contexts.


Many thanks!
