Low Variables + Conditionals?

Clearbold, LLC 24 Aug 2010 18:39 question, complete

Is it possible with Low Variables (1.2.5, EE 2.1) to check to see if the variable is empty? I.e.,

{if {my_variable}!=''}My variable: {my_variable}{/if}

In the examples, the <br /> in this line would be output if the variable was empty, which would be undesirable:

<span class="fn">{low_contact_fn}</span><br />

Thanks,
Mark

   Hey Mark,
   
   At the moment, you can only use vars in conditionals if you enable early parsing for those variables. Use syntax like you would with segment variables, like this:
   
   {if my_variable != ''}my conditional stuff{/if}
   
   I'm working on allowing conditionals using the {exp:low_variables:parse} template tags.

   Is this documented some place? I am using the last legacy version and I am trying to check if a grid has any rows...

   Only possible with a full tag, as mentioned in the second example here: http://gotolow.com/addons/low-variabl...
