custom conditionnal tag with OR operator ?

  • Hi,
    first of all thx for this great plugin !
    After hours searching in support forum i decide to ask. I have 3 custom attributes to manage contact informations for my events : contact-nom, contact-tel and contact-mail.
    I would like to show contact informations only if one of the 3 information is filled. for example :

    {has_contact-nom} OR {has_contact-tel} OR {has_contact-mail} // display contact infos

    for the moment i have this :

    <div class="event-contact">
<h3>Contact</h3>
<p>
{has_contact-nom} #_ATT{contact-nom} {/has_contact-nom}<br />
{has_contact-tel} <i class="fa fa-phone"></i> #_ATT{contact-tel} {/has_contact-tel}<br />
{has_contact-mail} <i class="fa fa-envelope-o"></i> <a href="mailto: #_ATT{contact-mail}">#_ATT{contact-mail}</a> {/has_contact-mail}
</p>
</div>

    but if the 3 contact informations are empty i still have the contact title which is no more necessary.

    Thx for Help

  • Hi,

    Glad you’re enjoying the plugin.

    I think the only solution fo this would be to create a custom conditional placeholder that checks to see if at least one of the custom attributes is set.

    This should help:

    Hi, thx for reply.
    Here’s my custom conditionnal placeholders function :

    // conditionnal tag for contact custom field in events
function em_event_output_condition_filter($replacement, $condition, $match, $EM_Event){
    // Checks for has_contact-nom conditional
    if(is_object($EM_Event) && preg_match('/^has_(contact-nom)$/', $condition, $matches)){
        if(array_key_exists($matches[1], $EM_Event->event_attributes) && !empty($EM_Event->event_attributes[$matches[1]]) ){
            $replacement = preg_replace("/\{\/?$condition\}/", '', $match);
        }else{
            $replacement = '';
        }
    }	

	// Checks for has_contact-tel conditional
    if(is_object($EM_Event) && preg_match('/^has_(contact-tel)$/', $condition, $matches)){
        if(array_key_exists($matches[1], $EM_Event->event_attributes) && !empty($EM_Event->event_attributes[$matches[1]]) ){
            $replacement = preg_replace("/\{\/?$condition\}/", '', $match);
        }else{
            $replacement = '';
        }
    }
	
	// Checks for has_contact-email conditional
    if(is_object($EM_Event) && preg_match('/^has_(contact-mail)$/', $condition, $matches)){
        if(array_key_exists($matches[1], $EM_Event->event_attributes) && !empty($EM_Event->event_attributes[$matches[1]]) ){
            $replacement = preg_replace("/\{\/?$condition\}/", '', $match);
        }else{
            $replacement = '';
        }
    }
    
    return $replacement;
}
add_filter('em_event_output_condition', 'em_event_output_condition_filter', 1, 4);

    Will try to it by myself but any help is appreciated ??
