Is there a way how to use variable in n:href or {link}?

Hey,
I guess this is a very simple problem for most of you. I have a search result from a few DB tables merged into one array, that means that each result could lead to the different presenter that's why I add another field in SELECT query where I specify which presenter belongs to the result row.
In latte template, I have one cycle for all results and I need to specify a link for each result to more than one presenter. This is what I've tried so far and nothing didn't work. Does someone know how this solve?
Is there a way how to use a variable in n:
macro or in
combination with {link}
function?
<div n:snippet="searchResults">
{foreach $results['results'] as $value}
// 1
<a href="{link $value->presenter:show $value->id}"><h3>{$value->title}</h3></a>
// 2
<a n:href="$value->presenter:show $value->id"><h3>{$value->title}</h3></a>
{/foreach}
</div>
EDIT:
I know that I solve it with this in presenter but I'd like to know if there is
a solution with Latte.
$url = $this->link('Product:show', $productId);

You can set name of parameter like this:
presenter:show, productId => $int, anotherOneParameter => $int1

I was just lazy. Important part is $value->id
→
productId => $value->id
.
This two generate different URLs:
/presenter/action/12
/presenter/action/productId=12

I know how this works, but for me, the important part of your example is
/presenter
I need to pass a variable here. Do you know what
I mean? I have a different presenter for each row so there cannot be single
presenter.

What is desired URL you trying reach?
Or something very very simple?
$value->presenter . ':show'

In Latte, when you need more complex expression, try to put it in double quotes. then you can usually use any expression you use in a double-quoted string in PHP.
Also, sometimes it helps to put an expression like
$value->presenter
to a temporary variable.
So try this:
<a href='{link "{$value->presenter}:show" $value->id}'>
or
{var $presenterName = $value->presenter}
<a href='{link "$presenterName:show" $value->id}'>

In newest Nette works fine even with parameter.

I was trying to do it with a temporary variable but I missed that fact I can use it in a double-quoted string. It works now, thank you.
