    Hello! A while back I had a question about displaying the terms that a user had chosen to filter their search by, and we’re using this: 

    <?php global $searchandfilter;
 
$sf_current_query = $searchandfilter->get(15)->current_query()->get_array();
echo '<strong>Filtered by:</strong>';
foreach($sf_current_query as $key) {
  echo '&nbsp; &bull; ' . $key['active_terms'][0]['name'] . ' ';
}
	?>

    Which works perfectly except that it’s blank when no terms have been selected, so the user sees “Filtered by:” and nothing else.

    Can I add to the php above, using an if / else combo?
    So: 

    if $sf_current_query is blank {
echo 'all';
else foreach($sf_current_query as $key) {
  echo '&nbsp; &bull; ' . $key['active_terms'][0]['name'] . ' ';
} ?>

    The “if” bit is where I’m lost – please help!

    If the query is empty, the $sf_current_query array will be empty, so you can use the PHP empty() function:

    if ( empty($sf_current_query ) ) {
  echo 'Nothing here folks.';
} else {
....
}

    I would think.

    Unfortunately that’s a no-go. The complete code I put in (using your good chunk there) looked like:

    <?php global $searchandfilter;
 
$sf_current_query = $searchandfilter->get(15)->current_query()->get_array();
echo '<strong>Filtered by:</strong>';

if ( is_empty($sf_current_query ) ) {
  echo "all";
} else {
  foreach($sf_current_query as $key) {
  echo '&nbsp; &bull; ' . $key['active_terms'][0]['name'] . ' ';
}	
}?>

    Am I missing something above if? Feels like that’s maybe where I’m off?
    (The page does not display anything – no sidebar, no search form, so as-is above it pretty broken – did I close off the function properly?)

    My bad. It was late when I wrote that.

    The function is just empty() not is_empty()

    Perfect, thank you!
