custom filter for placeholders

Can’t the EME conditional tags help you there? See
https://www.e-dynamics.be/wordpress/?cat=24

unfortunately not, because results are handled by another plugin; I’d need to hook a separate function to eme shortcodes before they get replaced.

maybe an idea using conditional tags would be to check the date and show the shortcode #ATTENDEES for future events and use another (new/unused) marker (eg #RESULTS) for past events. later hook to the final text using wp filters and replace this marker. This would work, if there always would be results, but in case where no results exist I still would like to display the list of attendees.

If your replacement would happen before eme replaces the placeholders, you could just check if your #RESULTS (or whatever) is empty and show the attendees then (using either eme conditional tags, or replacing #RESULTS by either the html you want, or by the string #_ATTENDEES, which eme will later replace by the list of attendees then).

correct, that would do. but how to get exactly there: after eme puts the templates together and before replacing the placeholders? does an appropriate filter exist already?

I added a filter called eme_events_format_prefilter, see if that works for you:

https://plugins.trac.www.ads-software.com/changeset/1048643

works pretty good, but one thing: it’ll be great to pass the event to the filter:

if (has_filter(’eme_events_format_prefilter’)) $format=apply_filters(’eme_events_format_prefilter’,$format,$event);

If you confirm that it works with $event as a second parameter then I’ll add it to the code.

confirmed, I currently have the following hack running pretty fine:

in events-manager.php in function eme_replace_placeholders():


if (has_filter('eme_events_format_prefilter')) $format=apply_filters('eme_events_format_prefilter',$format,$event);


and in my theme’s function.php:


function my_eme_events_format_prefilter($html, $event) {
...
}

add_filter('eme_events_format_prefilter', 'my_eme_events_format_prefilter', 10, 2);

Ok, implemented in trunk.
