@jkbb,
Thanks for raising this, I’ve looked at the uninstall code and it clearly isn’t robust enough to uninstall settings on Multisite installs as it doesn’t switch between database tables.
Basically, the code need to cycle through all the sub-blog tables removing the settings. I haven’t tested this uninstall.php code but it’s worth a try:
<?php
if ( !defined('ABSPATH') && !defined('WP_UNINSTALL_PLUGIN') ) {
// Make sure not to call this file directly
exit();
} else {
// Is this WordPressMU or not?
if ( isset($wpmu_version) || strpos($wp_version, 'wordpress-mu') ) {
$s2_mu = true;
}
if ( function_exists('is_multisite') && is_multisite() ) {
$s2_mu = true;
}
if ( $s2_mu ) {
global $wpdb;
$blogs = $wpdb->get_col("SELECT blog_id FROM {$wpdb->blogs}");
foreach ( $blogs as $blog ) {
switch_to_blog($blog);
s2_uninstall();
restore_current_blog();
}
} else {
s2_uninstall();
}
function s2_uninstall() {
global $wpdb, $table_prefix;
// get name of subscribe2 table
$public = $table_prefix . "subscribe2";
// delete entry from wp_options table
delete_option('subscribe2_options');
// delete legacy entry from wp-options table
delete_option('s2_future_posts');
// remove and scheduled events
wp_clear_scheduled_hook('s2_digest_cron');
// delete usermeta data for registered users
// use LIKE and % wildcard as meta_key names are prepended on WPMU
// and s2_cat is appended with category ID integer
$wpdb->query("DELETE from $wpdb->usermeta WHERE meta_key LIKE '%s2_cat%'");
$wpdb->query("DELETE from $wpdb->usermeta WHERE meta_key LIKE '%s2_subscribed'");
$wpdb->query("DELETE from $wpdb->usermeta WHERE meta_key LIKE '%s2_format'");
$wpdb->query("DELETE from $wpdb->usermeta WHERE meta_key LIKE '%s2_autosub'");
// delete any postmeta data that supressed notifications
$wpdb->query("DELETE from $wpdb->postmeta WHERE meta_key = 's2mail'");
// drop the subscribe2 table
$sql = "DROP TABLE IF EXISTS <code>" . $public . "</code>";
$wpdb->query($sql);
} // end s2_uninstall()
}
?>
