with ini_set('error_reporting', E_ALL|E_STRICT); unset array values/indices return an php error while parsing the template files. i'm not sure what the best solution for this problem is:
- a new command isset() within templates
- maybe a workaround with current functionality
- declare it as a bug and fix them inside php-sugar
I think the proper fix is to do the tests inside of the runtime engine and just return false or null for those lookups. I absolutely do not want template authors to have to add code to avoid PHP errors - that defeats half the purpose of using a template engine (protecting designers from the complexities and design mistakes of PHP).
That fix is in SVN. I also added the isset() function, since I realized that might be useful for some oddball use-cases. The function works a little differently than PHP's since I didn't want to make parser changes to support it. You call it like isset($array, 'value') and it returns true if $array['value'] exists. Also works for object properties.
thanks!
