Smarty - include template and update an existing variable

问题

I've recently started working with Smarty and I'm trying to find my way around. Here's what I don't know in the very moment:

I'm including a file:

{include file="nforum/_partials/box_forum.tpl"}

In that file, I have this:

<a href="{$t->link}">{$t->title|truncate:$link_truncate}</a>

I would like to pass $link_truncate a value of 30 while including the template (not inside the box_forum.tpl - that's important to me!)

I'm trying with:

{include file="nforum/_partials/box_forum.tpl" $link_truncate = 30}

without success. How can I do it?

回答1:

declare, before include the template:

{assign var="link_truncate" value="30"}
