複数のファイルをアップロードし、画像を空白にしても何もアップロードしない場合は、デフォルトの画像がそこにあるはずです

Question

ワンクリックで複数のファイルをアップロードしたい場合や、私が何かをアップロードしなければ、デフォルトのイメージがそこにあるはずです。しかし、コードは正常に動作していません。

ページはどのように見えますか？あなたはおそらくあなたの$s1から$s9への変数がそうでないために、より多くの情報（実際の出力、サーバからのエラーメッセージ、行が実際に挿入された場合など）を投稿する必要があります。実際には ''と等しい。 echo $s1;を試して、フィールドが空のままであるときの出力を確認してください。
