You can concatenate strings in php: expressions - just add spaces 
around ".", i.e.:


tal:attributes="class php:(a?'b':'c') . (d?' e':' f')"


Cool tip! I had already tried the "." concatenation but got no 
results, because of the missing spaces around the ".". Not I got it 
working, current looks like:




Session





The trim() is not neccessary - spaces around "." are just part of 
syntax and are not added to the string.


Currently this code might create "actlast" classs. If that's not what 
you wanted, then change 'last' to ' last' and optionally keep trim() 
(HTML ignores superfluous spaces in class attribute, so it's just 
aesthetical matter).
Yes, that trim() is just for aesthetical reasons. Good catch and your 
solution is what I had here (but on 'act ', with a space-suffix).


Cheers,
Ernesto

or you can use the ${} syntax:




That is true, and even looks a lot Smarty-ish. :)

alternatively, if you work with such classes a lot, you can make 
syntax nicer by writing your own expression modifier:


tal:attributes="class my_classes:repeat.item"

and create:

function ($argument,$nothrow)
{
  return 
'php_function_to_execute_when_template_runs('.phptal_tales($argument,$nothrow).')'; 


}

Indeed also a good suggestion, will keep that concept in mind when 
developing further.


Thanks a lot for your time and hints! I will keep up following this list.

Cheers,
Ernesto
