私のウェブサイトにmysqlキーワードの検索があり、正常に動作します。問題は、誰かが追加していないキーワードを検索し、結果ページに何も表示されない場合です。何も表示されず、メッセージが見つかりませんでした。私はこれを行う方法やコードを置く場所を完全に理解していません。私はコードが、私はこのコードは、私はまだこれに新たなんだ間違っている知っているこのmysqlデータの検索時にnull値のエラーメッセージを表示する方法
If($row_record['image']?="")
{echo row
}else
echo "<p>no results we're found</p>"
}
ようになります想像するだろうが、私はそれがそのようになります想像してみてください。ここでは、より良い理解を得るために、私の結果ページにあるすべてのコードをあらかじめありがとうございます。
