Question

I was wondering how would hide the text Location if the city state and country were not present and how would I let it display if any of the variables were present?

<p>Location:
<?php
 if (!empty($city))
     {
        echo $city .',';
     }

 if (!empty($state))
     {
        echo $state;
     }

 if (!empty($country))
     {
        echo ' ' . $country;
     }
?>    
</p>

Wrap it in a PHP block as well:

<?php

// Check if any of them is not empty.
if(!empty($city) || !empty($state) || !empty($country)){
    echo "<p>Location:";
    if (!empty($city))
    {
        echo $city .',';
    }
    if (!empty($state))
    {
        echo $state;
    }
    if (!empty($country))
    {
        echo ' ' . $country;
    }
    echo "</p>";
}
