[Plugin: Events Manager] How to hide empty custom items?

I found this tutorial and hope this will help you also; https://snippets.webaware.com.au/snippets/events-manager-conditional-placeholders-for-custom-attributes/

Thank you! This has helped!

I placed it in the file em-functions.php.

I ran into another problem. I do not know PHP, could you tell me how to change the website URL instead of text previewed Website?

The current code:

<a href="https://#_ATT{Website}" target="_blank">#_ATT{Website}</a>

Required:

<a href="https://#_ATT{Website}" target="_blank">Website</a>

When I give the required code, the text always “Website”, which is wrong.

Use, reference to Website, Facebook, Twitter etc…

actually, you can use <a href="#_ATT{Website}" target="_blank">#_ATT{WebsiteText}</a>; create a new attribute #_ATT{WebsiteText} or create a placeholder that will convert #_ATT{Website} to text

Thanks for the link, but it is beyond my knowledge ??

to the file I put em-functions.php

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\}/', '', $match));
                break;
            // #_LATT{Web}
            case 'has_latt_web':
                if (is_array($EM_Event->event_attributes) && !empty($EM_Event->event_attributes['Web']))
                    $replacement = preg_replace('/\{\/?has_latt_web\}/', '', $match);
                else
                    $replacement = '';
                break;
            case 'has_latt_facebook':
                if (is_array($EM_Event->event_attributes) && !empty($EM_Event->event_attributes['Facebook']))
                    $replacement = preg_replace('/\{\/?has_latt_facebook\}/', '', $match);
                else
                    $replacement = '';
                break;
            case 'has_latt_twitter':
                if (is_array($EM_Event->event_attributes) && !empty($EM_Event->event_attributes['Twitter']))
                    $replacement = preg_replace('/\{\/?has_latt_twitter\}/', '', $match);
                else
                    $replacement = '';
                break;
        }
    }
    return $replacement;
}
add_filter('em_event_output_condition', 'filterEventOutputCondition', 10, 4);

I do not know how to create #_ATT{WebsiteText}, #_ATT{FacebookText}, #_ATT{TwitterText} text and assign it “Website”, “Facebook” and “Twitter”. So I have not got great knowledge. Can you please help?
