registerFilter does not allow to use Anonymous functions(closures)

[ildar-aim]

The sample code is

    $tpl->registerFilter('output', function($source, $smarty){
        if ($smarty->smarty->isEvalTemplate($smarty->template_resource)) {
            return 'Test is passed.';
        } else {
            return 'Test is failed. Fix strpos in isEvalTemplate() method related to "eval:" string';
        }
    });

the possible fix is

-        if (!empty($template->smarty->registered_filters[$type])) {
+        if (isset($template->smarty->registered_filters[$type])) {

The function _get_filter_name returns wrong name for a closure
It results to
Warning: Illegal offset type to /lib/smarty3/sysplugins/smarty_internal_templatebase.php on line 699

PHP 5.3.29

Closure support is new added in the dev-master version.
It will be included in 3.1.28

Thank you.

May be an issue with two or more closure's filters.

1)first call to registerFilter returns
registered_filters[$type]['closure'] = closure_obj1

2)second call to registerFilter overwrites the first filter
registered_filters[$type]['closure'] = closure_obj2

The problem code is not uniq index in the _getFilterName function

return 'closure';

Should I open a new ticket related to non-unique filter names ?

[uwetews]

I updated NEW_FEATURES.txt to make it more clear.

If you register multiple closures use the new filter name parameter to assign unique filter names.

$smarty->registerFilter('pre', function($content) {return $content;}, 'name1');
$smarty->registerFilter('pre', function($content) {return $content;}, 'name2');
