まずは、商品を一括で登録しようとしたのですが、そこで早速躓きました。
ファイルのアップロードを行うと、文末のようなエラーがでerror_logがディスクを食いつぶすまでエラーを履き続けます。
最初に、数行のエラーが出た後は、feof/fgets/fwriteの繰り返しの状態で、そのタイミングでは、httpdがCPUを40%〜50%食い続けていました。
ログの最初の方にpermission errorが記録されていたので、TEMP_IMAGE のディレクトリのpermissionを 777 に変更し、再度試してみた所error_log#2の様になりました。
CSVファイルがTEMP_IMAGEのフォルダにアップロードされている事も確認できました。
一応1〜2歩位は前に進んでいるようですが、この後はソースを読むくらいしか対応を思いつきません。
どなたか解決にご協力いただけないでしょうか?
また、商品登録CSVの記載について詳細に記録されているドキュメントなどが見当たらなかったのですが、どこかにあるでしょうか?
長々と書きましたが、宜しくお願いいたします。

がると申します。
ひとつには、パーミッションエラーに属するものが出たときに、どうも「永久ループ」をしている様子なので。
このあたりはぜひとも改善をお願いしたいところなのですが。

もうひとつ、これに伴って。
私のBlogでも書いたのですが、このプログラムでつかっているfgetcsvで普通にCSVを読み込ませると「日本語が読めなくなる」可能性があります。
抜本的な対策はいろいろあろうかと思うのですが。
とりあえず極場当たり的には、
インストールディレクトリ/html/admin/products/upload_csv.php
のファイルで、行頭付近の適当な場所に

setlocale(LC_ALL, 'ja_JP');

の１文を入れることである程度ヘッジできる感じです(ある程度なので、検証は各自お願いします)。

以上、ちょいと気づいたので書き込みをしておきます。
