マジェント 1.7.0.2

次のコード編集を試みています: http://www.dnawebagency.com/displaying-new-products-in-magento-with-pagination

私はセットアップ中のサーバーでこれと戦ってきましたが、うまくいけばすぐに稼働し、動作させることができません。次の出力が表示されます。

致命的なエラー: 35 行目の /app/design/frontend/default/cscolors/template/catalog/product/list.phtml の非オブジェクトに対するメンバー関数 count() の呼び出し

35 行目:

<?php if(!$_productCollection->count()): ?>

いくつかのサンプル製品を使用してMagentoのクリーンインストールでこれを動作させることができましたが、何らかの理由で同じ手順に従っても新しい製品で動作させることができません.

この状況をデバッグし、そのコード行でハングする理由を理解するためにどこから始めればよいか本当にわかりません。このサーバーにはさらにいくつかのコード編集がありますが、それらはこの問題から切り離すべきです。基本的に 2 つのサーバーの唯一の違いは、いくつかの Magento Connect アドオンと、現在のテーマに含まれるいくつかの追加機能とテンプレート コードの編集です。

他のテーマを使用してみましたが、New.php ファイルのどこかで問題が発生していますが、これは新しいテスト サーバーで作業したものの正確なコピーであるため、ここからどこに行くべきか混乱しています。(私の知る限り)この問題を引き起こしているはずの 2 つのファイルは、上記のリンクに記載されている 2 つのファイル、/app/code/local/Mage/Catalog/Block/Product の New.php と / の list.phtml だけです。 app/design/frontend/default/currentthemedir/template/catalog/product. (デフォルトの list.phtml ファイルを使用して同じエラーが発生するため、これは技術的に問題とは無関係です)

必要に応じてさらにコードを提供できますが、前述のように、上記のリンクから直接コピーしました。

完全なファイルの一部を次に示します。

致命的なエラー: 35 行目の /app/design/frontend/default/cscolors/template/catalog/product/list.phtml の非オブジェクトに対するメンバー関数 count() の呼び出し

あなたの行は count()): ?>

$_productCollection は非オブジェクトであるため、インスタンスが作成されない理由を確認する必要があります。
