 Posted: Sun Aug 14, 2011 10:10 pm Post subject: Anonymous functions with Smarty |
 |
|
Hi,
is there any way to use anonymous functions within a smarty template?
Working example in PHP:
| Code: | $myFunction = function($foo) { return $foo . 'bar'; };
echo $myFunction('foo');
|
I tried to transfer the code to smarty, this way:
PHP:
| Code: | $myFunction = function($foo) { return $foo . 'bar'; };
$smarty->assign('myFunction',$myFunction);
|
Smarty:
| Code: | {$myFunction('foo')}
|
The attempt ended with a syntax error.
Any suggestions?
Thanks |

| Code: | function($foo) { return $foo . 'bar'; };
$smarty->register_function('isfoo', 'foo'); |
in Smarty2
or
| Code: | | $smarty->registerPlugin('function', 'isfoo', 'foo'); |
in Smarty3
use {isfoo} in template |

| Code: | $smarty = new Smarty();
$func = function($foo){ return $foo . " world"; };
$smarty->assign('func', $func);
$smarty->display("anonymous.tpl"); |
and currently lead to a compiler exception.
| Code: | $smarty = new Smarty();
$func = function($params, $template){ return $params['foo'] . " world"; };
$smarty->registerPlugin('function', 'func', $func);
$smarty->display("anonymous.tpl"); |
and currently lead to a fatal error, as smarty does not expect a callable thrown into registerPlugin().
So no, closures / lambdas / anonymous functions are not usable within a Smarty template at the moment. I'm not sure I like the general idea, though.

There are plenty of ways around it, such as a plugin wrapper:
{anon funcname="foo"}
I agree with globe, I'm not sure of the usefulness of this one. |

I'm not saying it couldn't be useful. I'm saying it's effing confusing for template developers (not knowing php). Anonymous functions would add another level of complexity to smarty templates, making them even harder to understand by non-programmers.

I don't think it would even be useful, ie. there would always be a better way. |

oops, I should have read better. Sorry for this.
btw, what is the use for an anonymous function called by varname? I can understand its shortened use in callbacks and equal.
Why should you want this working example to be an anonymous function?
| Code: | function foo($params, $template) { return $params['foo'] . " world"; }
$smarty->registerPlugin('function', 'isfoo', 'foo');
{isfoo foo="hello"} |
