ajax - Wordpress, wp-fullcalendar (0.8.4) with events manager (5.5.2): how to add additional text to title? -

i'm in nth hour of trying following: i'd add text/html snippets before title of event displayed in fullcalendar (i.e. inside of <div class="fc-event-title">). these snippets 1 of following:

1. <span class="info">registration needed</span>
2. <span class="cancelled">course cancelled</span>
3. <span class="ok">held planned</span>
4. blank value/no additional text

i tried copy wp-fullcalendar.php theme's directory hoping able edit function couldn't accomplish overwrite original file - anyplace tried put it.

i tried working in source file, test did (line 199 in original wp-fullcalendar.php):
$title = 'lll' . $post->post_title; did nothing output in calendar.

after while removed function 'function ajax()' wp-fullcalendar.php , calendar still displays fine. seems wrong place (which anyway it's source file, know).

i hoping find quick way accomplish task can see i'm stuck.

any on matter highly appreciated. thank you,

frank

update:

• i added custom attribute 'kurstyp' each event.
• possible values are: empty string (ie no span), 'please register', 'event cancelled', 'held planned'
• i non empty values appear within <div class="fc-event-title">
• best each wrapped in span individual class styling purposes

• this added wp-fullcalendar.php:

  add_action('wp_ajax_wpfc_custominfo',array('wp_fullcalendar','custominfo') ); add_action('wp_ajax_nopriv_wpfc_custominfo', array('wp_fullcalendar','custominfo') );  // , further down function custominfo() {      if( !empty($_request['post_id']) ){         $return = get_post_meta($_request['post_id'], 'kurstyp', true);     }     echo apply_filters('wpfc_custominfo', $return);     die(); }  // then, inside event.render part within fullcalendar_args if(event.post_id > 0) {     alert('event.title (1st): ' + event.title);     var custominfo = {action: 'wpfc_custominfo', post_id: event.post_id};     var = $.ajax({         url: wpfc.ajaxurl,         type: "post",         data: custominfo     });     extra.done(function(addtxt) {         event.title = addtxt + event.title;         alert('event.title (2nd): ' + event.title);     }); } alert('event.title (3rd): ' + event.title); 

  • addtxt delivers correct value 3rd alert fires before 2nd one, event.title remains unchanged
  • all of takes place in original source, i'd want change if worked
  • also, if worked: how style different messages accordingly?
  • might attribute classname of event object helpful , if so, how?

the texts used german, tried use english here better reading.

thanks help, frank
