Question

I’ve run into a funny problem. I need to use Smarty templates within a Smarty template.

Here is why. I use the same templates for various wiki websites, and each website has its own configuration. The configuration contains parts for the main template (such as changed titles and headings, etc).

Here is a simplified example. I’ve a file topic-list.template.html that’s shared across all websites:

<div id="topics">
  <h1>{$h1}</h1>
  ...
</div>

As you can see, this template file contains an <h1> tag that can be customized for each website.

Then for each of the websites I’ve a configuration file that looks like this (simplified):

$config = [
  "h1-titles" => [
      "topics" => "Showing Topics in {\$category}"
  ]
];

As you can see the configuration file contains a Smarty template.

So when I render the topic-list.template.html file, I’ve to render the $config['h1-titles']['topics'] first through $smarty->fetch("string":$config['h1-titles']['topics']), and then assign it to h1 Smarty variable. My simplified code looks like this:

$h1_tag = $smarty->fetch("string":$config['h1-titles']['topics']);
$smarty->assign('h1', $h1_tag);
$smarty->display('topic-list.template.html');

I wonder if I could somehow insert the $config['h1-titles']['topics'] in the topic-list.template.html file automatically and then it have all rendered in one go?

Please have a look at the docs on String Template Resources. You will immediately notice that your $smarty->fetch('string:…') approach can also be done within a template: {include file="string:…"}
