Displaying meta fields that hold multiple values (2 posts)

    As the doc states: only the first element of each meta field is displayed when using {META[metafieldname]}

    I threw together a very quick , dirty , probably not optimal, not working in every case, ... :) hack that allows me to display my meta field as a comma separated list in case there is more than 1 value.

    Around line 336 in plugins/recent-posts-plus/recent-posts-plus.php
    there is a line that says foreach($meta_matches[0] as $key => $meta_match) {

    I changed the code in that foreach-loop with the following...
    And again : disclaimer ; this is very quick and dirty - don't have alot of time to think this through for all usecases, I need to get this site finished. you know how it is.

    foreach($meta_matches[0] as $key => $meta_match) {
    
    if(!empty($meta_matches[1][$key])) {
    $the_metadata = get_post_meta($ID, $meta_matches[1][$key], true);
    
    // META field has multiple values.
    if (is_array($the_metadata)) {
    foreach ($the_metadata as $element) {
    $post_id = get_post($element);
    $title = $post_id->post_title;
    $widget_ouput_template_params[$meta_match] .= $title . ",";
    }
    $widget_ouput_template_params[$meta_match] =     trim(rtrim($widget_ouput_template_params[$meta_match]),",");
        } else {
        // META field just has ONE value.
        $widget_ouput_template_params[$meta_match] = $the_metadata;
        }
    } else {
        $widget_ouput_template_params[$meta_match] = '';
    }
    }
