[Plugin: Gigs Calendar] Substitute Feedburner RSS Feed

Well, here is the quick way: go to your gig calendar’s template directory, which reside either in

wp-content/plugins/gigs-calendar/templates/[chosen]/

or if you customized it in

wp-content/gigs-templates/[chosen]/

and look for an file name rss.php. Open it and you will see

<?php if ( $options['rss-link'] ) : ?>
	<div class="gigs-rss"><a href="<?php echo $folder ?>rss.php"><?php _e('Subscribe to RSS calendar feed', $gcd); ?></a></div>
<?php endif; ?>

Replace <?php echo $folder ?>rss.php with your Feedburner RSS.

A less trivial but cleaner solution (better browser support for the file downloaded) would be to add a LINK-tag to the header of the html output. This should be done anyways, no matter of the feed provider!

Open

wp-content/plugins/gigs-calendar/gigs-calendar.php/

and at line 66 (somewhere around there, at least) you should be able to see

function display_css() {
  $options = get_option('gigs-calendar');
  $folder = dtc_gigs::get_url() . 'templates/';
  if ( is_file(dirname(__FILE__) . '/templates/' . $options['template'] . '/style.css') ) {
  ?>
  <link type="text/css" rel="stylesheet" href="<?php echo $folder . $options['template']; ?>/style.css" />
  <?php
  } elseif ( is_file(ABSPATH . 'wp-content/gigs-templates/' . $options['template'] . '/style.css') ) {
  ?>
  <link type="text/css" rel="stylesheet" href="<?php echo get_bloginfo('wpurl') . '/wp-content/gigs-templates/' . $options['template']; ?>/style.css" />
  <?php
  } else {
  ?>
  <link type="text/css" rel="stylesheet" href="<?php echo $folder; ?>basic/style.css" />
  <?php
  }
}

Go to the end of that function right before the last } and insert the following code:

// EDIT START:
global $gcd;
$feedburner_rss_url = "";
$title = __('Upcoming Gigs feed', $gcd) . " | " . get_bloginfo('name');
if (!empty($feedburner_rss_url)) {
  ?>
  <link rel="alternate" type="application/rdf+xml" title="<?php echo $title ?>" href="<?php echo $feedburner_rss_url?>" />
  <?php
} elseif ( is_file(dirname(__FILE__) . '/templates/' . $options['template'] . '/style.css') ) {
  ?>
  <link rel="alternate" type="application/rdf+xml" title="<?php echo $title ?>" href="<?php echo $folder . $options['template']; ?>/rss.php" />
  <?php
} elseif ( is_file(ABSPATH . 'wp-content/gigs-templates/' . $options['template'] . '/rss.php') ) {
  ?>
  <link rel="alternate" type="application/rdf+xml" title="<?php echo $title ?>" href="<?php echo get_bloginfo('wpurl') . '/wp-content/gigs-templates/' . $options['template']; ?>/rss.php" />
  <?php
} else {
  ?>
  <link rel="alternate" type="application/rdf+xml" title="<?php echo $title ?>" href="<?php echo $folder; ?>basic/rss.php" />
  <?php
}
// EDIT END

Now, if you do not touch the rss.php of your chosen template, the rss-feed of gigs calender will be linked in the header and the feed is delivered by the wp-server.

If you edit the rss-file to have your feedburner-feed served and you inserted the code above, you must set the $feedburner_rss_url to the same URL that you entered in the rss.php!

$feedburner_rss_url = “https://https://feeds2.feedburner.com/someentryhere&#8221;;

Though it’ll work, I forgot something. The type of the feed should be edited as well and set to type of the (external) feed. So this is the code to insert:

// EDIT START:
global $gcd;
$feedburner_rss_url = "";
$feed_type = "rss";
$title = __('Upcoming Gigs feed', $gcd) . " | " . get_bloginfo('name');
if (!empty($feedburner_rss_url)) {
  ?>
  <link rel="alternate" type="application/<?php echo feed_type; ?>+xml" title="<?php echo $title ?>" href="<?php echo $feedburner_rss_url?>" />
  <?php
} elseif ( is_file(dirname(__FILE__) . '/templates/' . $options['template'] . '/style.css') ) {
  ?>
  <link rel="alternate" type="application/<?php echo feed_type; ?>+xml" title="<?php echo $title ?>" href="<?php echo $folder . $options['template']; ?>/rss.php" />
  <?php
} elseif ( is_file(ABSPATH . 'wp-content/gigs-templates/' . $options['template'] . '/rss.php') ) {
  ?>
  <link rel="alternate" type="application/<?php echo feed_type; ?>+xml" title="<?php echo $title ?>" href="<?php echo get_bloginfo('wpurl') . '/wp-content/gigs-templates/' . $options['template']; ?>/rss.php" />
  <?php
} else {
  ?>
  <link rel="alternate" type="application/<?php echo feed_type; ?>+xml" title="<?php echo $title ?>" href="<?php echo $folder; ?>basic/rss.php" />
  <?php
}
// EDIT END

An these are the lines you have to edit to use external feed providers:

$feedburner_rss_url = “https://feeds2.feedburner.com/someentryhere&#8221;;
$feed_type = “rss”; // usually rss, rdf or atom
