Low variable and Select Categories

Samsull 11 Oct 2012 11:35 question, complete

Hi,

I have a Low Variable using Select Categories type.

It's blank on the front end - isn't it supposed to work like a Select variable type?

{exp:low_variables:options var="lv_industry_sector"}
{lv_industry_sector:data_label}
{/exp:low_variables:options}

   Hi Sam,
   
   About the Options tag:
   
   

   This tag pair allows you to display the options for a given variable. Use this in combination with the Checkbox Group, Radio Group and Select variable types.

   
   
   So, you can't use that tag using a Select Categories var type, which returns:
   
   

   [...] either the category id of the single selected item or a list of selected category ids, separated by the chosen separator.

   
   
   To get a list of the categories you selected, you'll need to use the variable as input for a exp:channel:categories tag or a exp:query tag.

   No problem, just curious. Using the categories tag is fine eg:

   Thanks for your lightening fast response!

   Cool. You could use the Show parameter to only show the categories selected in the LV.

   Any idea how I can control the display order of categories listed via the exp:channel:categories tag?

   Since the channel:categories tag doesn't support a fixed_order parameter, you'll have to use the Query module instead. Make sure the Separator setting for the variable is set to comma.
   
   

   {exp:query sql="SELECT cat_name, cat_url_title 
      FROM exp_categories 
      WHERE cat_id IN ({my_category_var}) 
      ORDER BY FIELD(cat_id, {my_category_var})" 
    } 
      {cat_name} 
    {/exp:/query}
