CiviCRM Community Forums (archive)

As you may know the switching mechanism is not working for both systems. This thread will document my attempt to make a working block with php to solve this issue until it is resolved in civicrm core.

1) Description of the problem
Drupal switching does not switch the civicrm system, and similarly civicrm does not switch drupal. I believe this is the case because there is not a unified vision of language integration. I agree with the discussion that even on non-english sites the admin NEEDS to be using the English maintenance, however it seems to me that civicrm uses an "all-or-nothing" approach to language integration.

2) Details
When you enable a second language, a block is enabled that allows you to switch the civicrm language. This block uses javascript and appends the link with:

"[? or &]lcMessages=[selected language from list of enabled languages]";

Unfortunately, it does not check if lcMessages is already set, and will stupidly append so you get something like:

"?lcMessages=de_DE&lcMessages=en_US&lcMessages=de_DE" if you use the drop-box select multiple times, which is a common method when developing multilingual sites.

Furthermore, this "system" is never registered with drupal, so it is impossible for Drupal to force this, and the "Inherit CMS Language" in the Settings->Localization panel doesn't work at this time...

-----

this is the code in file LangSwitch.tpl:

{if isset($langSwitch) and $langSwitch|@count > 1}
  <form action="#">
    <select name="lcMessages" onchange="window.location='{$smarty.server.REQUEST_URI}{if strpos( $smarty.server.REQUEST_URI, '?' ) === false}?{else}&{/if}lcMessages='+this.value">
      {foreach from=$langSwitch item=language key=locale}
        <option value="{$locale}" {if $locale == $tsLocale}selected="selected"{/if}>{$language}</option>
      {/foreach}
    </select>
  </form>
{/if}

this is a snippet for a block. it has two or three problems at the moment, and I see it as a temporary workaround, however it works well enough to help the staff not get confused when they are new to the site and need to switch the language quickly and globally.
unfortunately the link to civicrm (from the navigation link) does not respect the language as set, so I have removed that on my setting and added it here.
