php - Wordpress Ajax setcookie WAMP/LAMP 格差

Question

e コマース用の wordpress テーマ プラグインでは、Cookie を設定する 2 つの ajax/php スクリプトがあります (両方とも同じディレクトリにあります) ajax 呼び出しは同じ "cart.js" から設定されます。カートが作成または更新されます。2 つ目は、カートが PayPal に渡される前に、顧客/ユーザーが存在するかどうかを確認するか、または新たに作成し、どちらの場合も、まだログインしていない場合はログインします。そのため、paypal から戻ると、顧客/ユーザー (現在ログイン中) には、注文のステータス (新規および旧)の概要/レビューが表示されます。

私の WAMP 開発スタックでは、これは問題なく動作しますが、ホストされた (Linux) インストールでは、cart_cookie スクリプトは期待どおりに動作しますが、checkout/customer_cookie はスローされます...

PHP Warning:  session_start()
    [<a href='function.session-start'>function.session-start</a>]:
        Cannot send session cache limiter - headers already sent
            (output started at /home2/alternam/public_html/demo/wp-content/themes/AM_Wallaby_Kids/checkout.php:2)
                in /home2/alternam/public_html/demo/wp-content/plugins/cat-man/catalog-manager.php on line 23

その後、ユーザーはログインせず、カートは変換されません(関連する顧客データで更新されます)。これを最小限に抑える方法を見つけたいと思いますが、プラットフォーム間で 2 つのスクリプトの動作が異なる理由がわからないため、長い投稿について事前にお詫びし、両方を以下にすべて含めて、質問します。誰かが格差の明白な理由を見ることができれば? お待ち頂きまして、ありがとうございます。
