i was trying to figure out how to pass variables i get in an INI file to javascript (i'm interested in passing a language file here)

i thought of many way to do this but none worked yet (javascript ini parser i.e.).

I think a quite simple way to achive this would be to pass variables thru json using javascript

my config file is dynamicaly load using
Code:
{config_load scope="global" file="lang/`$smarty.session.lang`.txt"}

(using a session variable)

this works fine

now i've tried codes such as :

Code:
<script type="text/javascript">
   lang = {$smarty.config|@json_encode};
</script>


or

Code:
<script type="text/javascript">
   {foreach from=$smarty.config item=data}
      {$data}
   {/foreach}
</script>


but i still get this warning :
Quote:
Missing argument 1 for Smarty_Internal_Data::getConfigVariable()


is there a way to loop on variables i get from a config file for example ?
or do you think of any total different way to do that ?

any help appreciated !

thanks !

$smarty.config is not a real array of the config variables.
There is no direct way to loop over all config variables from within the template.

But you can create such array at PHP scrip level and assign that array to a Smarty template variable.

See http://www.smarty.net/docs/en/api.config.load.tpl and http://www.smarty.net/docs/en/api.get.config.vars.tpl
