FYI – adding event date to RSS feed

Just if anyone needs it – it is possible to add the post event date to the RSS feed of ‘posts’.

I have created a simple ‘plugin’ (added a folder ‘rssaddeventinfo’ into ‘plugins’ and added a rssaddeventinfo.php in there) that you can just enable to have this feature.

Unfortunately, I found only a way how to publish event start date, and not the end date, times and so on.

<?php
/*
Plugin Name: RSSaddRsEventMultidayEventInfo
Plugin URI: https://mypage.sk
Description: My custom plugin that gets post custom data from plugin ‘rs-event-multiday’ and adds it into RSS as new tag
Version: 1.00

add_action( ‘rss2_item’, ‘add_eventinfo_to_rss’ );
add_action( ‘rss2_ns’, ‘add_eventinfo_to_rss_namespace’ );

function add_eventinfo_to_rss_namespace()
{
echo “xmlns:ev=\”https://purl.org/rss/1.0/modules/event/\”\n”;
}

function add_eventinfo_to_rss()
{
$custom_fields = get_post_custom();
$event_start = $custom_fields[_rs_event_start][0];
if ($event_start != 0)
{
echo “<ev:startdate>”.gmdate(“c”, $event_start).”</ev:startdate>\n”;
}
}
