WP in Mono-site, Undefined array key "id_column_exists" warning log #284
Description
Hi,
id_column_exists variable is not defined when wordpress is in mono-site mode.
Warning: Undefined array key "id_column_exists" in //wp-native-php-sessions/pantheon-sessions.php on line 562
My proposal is to modify pantheon-sessions.php like following
public function add_index( $start_position ) {
global $wpdb;
$output = [
'no_session_table' => 0,
'id_column_exists' => 0,
];
if ( ! is_multisite() ) {
$this->safe_output( __( 'Single site detected. Beginning processing... \n', 'wp-native-php-sessions' ), 'log' );
$this->add_single_index( $wpdb->prefix, $output );
$this->safe_output( __( 'Operation complete, please verify that your site is working as expected. When ready, run wp pantheon session primary-key-finalize to clean up old data, or run wp pantheon session primary-key-revert if there were issues.', 'wp-native-php-sessions' ), 'log' );
return;
}
$this->safe_output( __( 'Multisite installation detected. Processing Sites individually...', 'wp-native-php-sessions' ), 'log' );
$site_list = $this->get_all_sites( $start_position );
$site_count = count( $site_list );
