sample for using php code

Using the token-module is definitely easier for the simple things you can do with it.
But, if I want different title-setting depending on some input-values, I need to use php-control structures ("if" and/or "switch" statement), and so far I haven't found a way to combine those with tokens ...

Thank a lot, that got me almost to where I want to be.

Question: do you invoke the php-code at a different time than the token replacement?
The reason I ask is that content_format(...) on a date field brings me back to the old problem of returning "January 1. 2007" while that's already working now when using the token module ...

Is it possible to call this php-code in a context with variables according to the possible cck-fields in this node-type available?

I still think a context providing the variables would make life easier, but I got it working now:

<?php
global $form_values;
$node = (array)$form_values;
$gegner = content_format('field_gegner',
                         $node['field_gegner'][0]);
$heim = $node['field_heimspiel']['keys'];
if($heim) {
  print "MyTeam - $gegner";
} else {
  print "$gegner - MyTeam";
}
?> am [field_datum_0-view]

Depending on the value of field_heimspiel (integer - checkbox), the home-team or the visitor-team is printed first in the title, followed by the date (field_datum_0) the match is to be played on.

Instead of evaluating 'field_gegner' myself I could also have changed context to html and printed the token:

... ?>[field_gegner-formatted]<?php ...

You only have to take care the place of the token could be replaced by a php print-statement.

Getting the right incantation $node['field_heimspiel']['keys']; took me some print_r(...) debugging since the devel-module shows different properties for then node there, but otherwise it's quite straight-forward since you can use the tokens outside of php-context.
