MySQL5.0xにアップグレードしたらこのエラーでカテゴリーをクリックしても表示されない現象が出た。

いろいろ記事は載っていたが肝心のソース部分がなかなか見つからなかった。。。orz

こちらのサイト様にソースが記載されていたので覚え書きの意味でこちらに記しておきます。

当方の環境はPHP4です。

なお、ZenCart1.3.ｘではこの現象は回避されているそうです。

ZenCart/includes/modules/meta_tags.php 176行目付近

ZenCart/includes/blocks/blk_advanced_search_result.php 85行目付近

また、MySQLのcharacter_setが下記のようだったらZenCart/includes/classes/db/mysql/query_factory.phpの39行目付近でSET NAMEでujisを指定してやる。

character_setがutf8だったらujis指定しなければ当然ZenCartでは文字化けするはずである。

mysql> SHOW VARIABLES LIKE 'char%';

ZenCart/includes/classes/db/mysql/query_factory.php の39行目付近に下記を追加。

mysql_query("SET NAMES ujis");
