Conditional Placeholder with Custom Attributes

Hi there,

I put the following code in the themes functions.php

/**
* add some conditional output conditions for Events Manager
* @param string $replacement
* @param string $condition
* @param string $match
* @param object $EM_Event
* @return string
*/
function filterEventOutputCondition($replacement, $condition, $match, $EM_Event){
    if (is_object($EM_Event)) {

        switch ($condition) {

            // replace LF with HTML line breaks
            case 'nl2br':
                $replacement = nl2br(preg_replace('/\{\/?nl2br\}/', '', $match));
                break;

            // #_ATT{Homepage}
            case 'has_att_homepage':
                if (is_array($EM_Event->event_attributes) && !empty($EM_Event->event_attributes['Homepage']))
                    $replacement = preg_replace('/\{\/?has_att_homepage\}/', '', $match);
                else
                    $replacement = '';
                break;

        }

    }

    return $replacement;
}

add_filter('em_event_output_condition', 'filterEventOutputCondition', 10, 4);

And the following in Formatting > Events > Single Events

{has_att_website}
Text
{/has_att_website}

I would like to hide the Custom Attribute #_ATT{Website} when it’s empty. But it’s gone anyway even if there is a url in there.

Any thoughts?

Cheers
