Question

I’m using Smarty and utilizing the config_load respective {#VAR#} variables to implement localization. This is working perfectly fine as long as the content is within the templates, but fails as soon as I have to add dynamic content within the TPL file, i.e. with:

{if isset($var) }
    {foreach from=$var item=line}
        {$line}<br>
    {/foreach}
{/if}

Please note each entry within $var contains usually one {#VAR#} entry – and they are not translated (the user will see {#VAR#}).

What is the proper way to implement localization in this case?

Solution

I ended up by only replacing {$line}<br> in the code above with:

{eval var=$line}

That did the trick for me.

Answer 1

You are probably looking for something like {eval}

Take a look at {eval} documentation.

On your situation, you could try this:

example.php

<?php
  (...)
  $var = array("{#OK#}", "{#CANCEL#}");
  $smarty->assign('var', $var);
  $smarty->display('example.tpl');
?>

example.config

OK = Okay
CANCEL = Nevermind

example.tpl

{config_load file='example.config'}

<h1>Template stuff</h1>

{if isset($var) }
  {foreach from=$var item=line}
    {eval var=$line}<br>
  {/foreach}
{/if}

Hope that helps! 🙂
