Problem with conditional placeholder for Location custom field

    I have used the following function in functions.php to show the attribute #_LATT{gomap-link} on the Location page only if the attribute is set:

    function filterLocationOutputCondition($replacement, $condition, $match, $EM_Location){
    if (is_object($EM_Location)) {
 
        switch ($condition) {
 
            // replace LF with HTML line breaks
            case 'nl2br':
                // remove conditional
                $replacement = preg_replace('/\{\/?nl2br\}/', '', $match);
                // process any placeholders and replace LF
                $replacement = nl2br($EM_Location->output($replacement));
                break;
 
            // #_ATT{gomap-link}
            case 'has_gomap-link':
                if (is_array($EM_Location->location_attributes) && !empty($EM_Location->location_attributes['gomap-link']))
                    $replacement = preg_replace('/\{\/?has_gomap-link\}/', '', $match);
                else
                    $replacement = '';
                break;
        }
    }
    return $replacement;
}
 
add_filter('em_location_output_condition', 'filterLocationOutputCondition', 10, 4);

    Unfortunaltely it doesn’t do what i expected. I use the following code in the plugin settings (Formats/Locations):

    {has_gomap-link}<a href="#_LATT{gomap-link}">PokemonGoMap.info</a><br/>{/has_gomap-link}

    what is displayed as the result is any case:

    {has_gomap-link}PokemonGoMap.info
    {/has_gomap-link}

    Where is my mistake?
    Thank you in advance

  • Hi, EM User here too ??

    Personally I have always had problems with creating conditional placeholders with {}. So, I usually create a normal placeholder with an if/else condition. I tested this for you and it works:

    
function my_em_placeholder_mod($replace, $EM_Location, $result){
if ( $result == '#_GOMAP' ) {
		if( !empty( $EM_Location->output("#_LATT{gomap-link}" ) ) ){
			$replace = '<a href="#_LATT{gomap-link}">PokemonGoMap.info</a><br/>';
		} 
		else {
			$replace = '';
		}
	}
	return $replace;
}
add_filter('em_location_output_placeholder','my_em_placeholder_mod',1,3);

    Then just use #_GOMAP instead go the {has_gomap-link}… {/has_gomap-link}. The #_GOMAP placeholder will then check itself if he has to output anything ??

    Hi Patrick,
    thank you very much. It worked for me but I had to write 

    
if ( $result == '#_GOMAP' ) {
		if( !empty( $EM_Location->output("#_LATT{gomap-link}" ) ) ){
			$replace = '<a href="' . $EM_Location->output("#_LATT{gomap-link}") . '">PokemonGoMap.info</a><br/>';;
		} 
		else {
			$replace = '';
		}

    Best regards
    Burkhard

    You’re welcome ??

    Ah, I guess that difference depends on where you use the placeholder. Your version is more “allround proof”, apparently. LOL. ??
