        // Check if title attribute is already present
        if (!preg_match('/title="/i', $img_tag)) {
            // Find the `alt` attribute value
            preg_match('/alt="([^"]*)"/i', $img_tag, $alt_matches);
            $alt_text = isset($alt_matches[1]) ? $alt_matches[1] : '';

Reactivate an expired cancelled subscription

With this snippet it is possible to reactivate an expired subscription with the “expired” status. Once the snippet has been activated, you must visit the following url by modifying yourdomain.com with the domain of your site and replacing 123 with the subscription id.

https://yourdomain.com/wp-admin/admin-post.php?action=force_subscription_reactivation&subscription_id=123

add_action('admin_post_force_subscription_reactivation', 'force_subscription_reactivation');

function force_subscription_reactivation() {
    if (!current_user_can('manage_woocommerce')) {
        wp_die(__('Non hai i permessi per eseguire questa azione.', 'woocommerce'));
    }

    $subscription_id = isset($_GET['subscription_id']) ? absint($_GET['subscription_id']) : 0;

    if ($subscription_id) {
        $subscription = wcs_get_subscription($subscription_id);

        if (!$subscription) {
            wp_die(__('Subscription non trovata o ID non valido.', 'woocommerce'));
        }

        if ($subscription->has_status('expired')) {
            try {
                // Aggiorna le date obbligatorie per evitare errori
                $new_next_payment_date = gmdate('Y-m-d H:i:s', strtotime('+1 month')); // Esempio: 1 mese da oggi
                $new_end_date = gmdate('Y-m-d H:i:s', strtotime('+6 months')); // Esempio: 6 mesi da oggi

                $subscription->update_dates([
                    'next_payment' => $new_next_payment_date,
                    'end'          => $new_end_date,
                ]);

                // Aggiorna lo stato forzatamente
                wp_update_post([
                    'ID'          => $subscription_id,
                    'post_status' => 'wc-active',
                ]);

                // Salva i cambiamenti nella subscription
                $subscription->save();

                wp_redirect(admin_url('edit.php?post_type=shop_subscription'));
                exit;
            } catch (Exception $e) {
                wp_die(__('Errore durante la riattivazione della subscription: ' . $e->getMessage(), 'woocommerce'));
            }
        } else {
            wp_die(__('La subscription non è nello stato expired.', 'woocommerce'));
        }
    }

    wp_die(__('ID della subscription non valido.', 'woocommerce'));
