syntax error: expecting '=' after attribute name

It is not currently possible to create a Smarty function as follows: {testfunc option} There are situations where it would be useful to allow single word parameters/options (eg "hidden"), which currently require instead {testfunc option=value} How trivial is it to change this so that if the =value is missing a value of TRUE is passed to the handler for that parameter, instead of generating an error? Ie, so that the following are equivalent: {testfunc option} {testfunc option=TRUE} It ought to be simple enough, but I just had a look at the tokeniser in Smarty_Compiler::_parse_attrs and got a bit lost :-( The specific use I had for this is a bit obscure, in that I'm trying to create a comment function which I can use to tempoarily skip certain parts of templates, eg: {include file="mytemplate.tpl"} becomes: {xx include file="mytemplate.tpl"} .. where xx simply does nothing; of-course this won't work because include then needs a value after it. But also consider situations where {checkbox name="test" value="testval" checked} is more readable than {checkbox name="test" value="testval" checked=1} -- Mark Rogers, More Solutions Ltd
