    Hi everyone !
    I am building a website using Foundation Framework, one of the many functions it has is the 'interchange images'.
    The problem is that to include a TV or a Chunk inside this Foundation function using [[ ]] is not working, for Foundation also uses [ ].
    I am trying 
    <div data-interchange="[[[*TVname]], small], [[[*TVname]], medium]"></div>

    Is there a way to make this work?

    For your help, many thanks !

      Assuming you're getting the TV value of the current document, you could write a small snippet (geTVValue) to handle this:
      // get the TV name
$tv     = $modx->getOption('tv', $scriptProperties, '');
// get the TV value of the current resource
$value  = $modx->resource->getTVValue($tv);
$output = '<div data-interchange="[' . $value . ', small], [' . $value . ', medium]"></div>';
return $output;


      Then on your page, call it like this:
      [[geTVValue? &tv=`TVname`]]


      You could put your HTML in a chunk for a cleaner code.

        Excellent snippet and solution above.

        An idea is to see if escaping the brackets would work:
        <div data-interchange="\[[[*TVname]], small\], \[[[*TVname]], medium\]"></div>

          I think this would work and would be a lot simpler (assuming that whatever is processing the data-interchange parameter doesn't care about white-space -- and I bet it doesn't):

          <div data-interchange="[ [[*TVname]], small], [ [[*TVname]], medium]"></div>

            I also used htmlentities for Problems like this with [ &#91; and ] &#93;

            or create an output filter which returns the value wrapped by brackets
