特定の郵便番号と選択した半径内のすべての組織を検索する検索機能を Web サイトに組み込みました。この部分はうまく機能します。私は現在、カテゴリー検索も取り入れようとしています。そのため、選択した郵便番号内のすべての組織を検索するだけでなく、選択した郵便番号内の選択したカテゴリー内のすべての組織を検索します。ただし、次のエラーが発生します。
致命的なエラー: C:\xampp\htdocs\caretest\include\header.php の 104 行目の未定義関数 preg__match() の呼び出し
これはおそらく if ステートメントでの preg_match 関数の何らかの誤用によるものだと確信していますが、それを適切に使用して機能させる方法がわからないか、これを行うより良い方法があるかどうかはわかりません同様に問題ない preg_match を含めないでください。ありがとう。
コードは次のとおりです。
