Use template tag and language variable

Fernstrg 10 Jul 2011 19:18 question, complete

Hi,

I made a multi-language site using Structure, so there's no global language variable. I pull the current language from a URL segment and use a "preload_replace" to insert it into the various tags in my template.

This apparently means I cannot use the advanced features of Low Variable's {exp:low_variables:parse} tag, like for example the format parameter or the site prefix (which would save me recreating the fields in all three sites in this MSM installation).

Is there a way to use "preload_replace" AND the {exp:low_variables:parse} tag?

   Hi!
   
   I'm not quite sure what you're trying to do. Do you have a code example? And I'm sure you've seen my parse order cheat sheet, right?

   I want to for example display my variable with <br/> formatting.

   Okay, so then you'd use the {exp:low_variables:parse var="my_textarea_var" format="br"} right?
   
   How does the preload_replace variable fit into this?

   It's {exp:low_variables:parse var="my_textarea_var_{my_language_switch}" format="br"} and the "{my_language_switch}" is a preload replace variable.

   Okay, and how are you setting the preload replace variable?

   It grabs the language snippet from a URL segment.
   {preload_replace:lang_switch="{if segment_1 == 'de' || segment_1 == 'en'}{segment_1}{if:else}nl{/if}"}

   Aye, there's the rub. You're using an advanced conditional there. Parse order will mess this up.
   
   Try this instead:
   
   

   {if segment_1 == 'de'} 
      {preload_replace:lang_switch="de"} 
    {/if} 
    {if segment_1 == 'en'} 
      {preload_replace:lang_switch="en"} 
    {/if} 
    {preload_replace:lang_switch="nl"}

   
   
   It's more verbose, but this way, the {lang_switch} variable will actually contain either 'de', 'en' or 'nl'. If you use your method, the variable will contain the actual conditional instead of the resolved value.

   That works, thank you!

   You're welcome!
