Low Variables & Conditionals: if variable has a value, display content

ctrlaltdel 13 Dec 2013 20:16 question, complete

Hi Low,

I couldn't find an answer to this, so I apologize if this has already been solved here on the forums or in the docs.

I'm using Low Variables to display "global" information on my site in the footer. For instance: global contact information (address, phone, fax), and social media links (twitter, fb, linkedin). I only want to display the variable value(s) and their surrounding markup if the variable actually has a value.

Is there a preferred way to do this?

Currently, this is how I'm doing it in my template, and this works:

 
 {exp:low_variables:pair var="low_cli_social_twitter"} 
   {if low_cli_social_twitter} 
     <li class="social-media-twitter"> 
       <a href="{low_cli_social_twitter}" rel="me"> 
         <span class="icon-twitter"></span> 
         <span class="screen-reader-text">Follow COMPANY on Twitter</span> 
       </a> 
     </li> 
   {/if} 
 {/exp:low_variables:pair}

   If you enable early parsing for a variable, you can use the variable syntax and use it in a conditional:
   
   

   {if lv_my_var} 
      ... {lv_my_var} ... 
    {/if}

   Thank you, Low. That worked! I appreciate the help.
