ユーザーが 3 種類の検索から選択できる検索セクションを自分の Web サイトに作成したいと考えています。名前で検索、専門分野で検索、または場所で検索できます。
出力は、名、姓、およびプロフィール写真になります。
問題は、このコードの構造とクエリの書き方がわからないことです。
これは私が書こうとしたものですが、多くのエラーが発生します:
- お知らせ : 未定義 索引 : 地区
- お知らせ : 未定義 索引 : 村
- 注意: 未定義のインデックス: sql
- 警告 :mysql_fetch_array() は、パラメーター 1 が resource 、null であることを期待しています
