こんにちは、ユーザーに写真のアップロードを求めるフォームがあります。これは、imagecreatefromjpg および imagecopyresampled で写真を 2 番目の画像 (別の画像の上に重ねた画像) として使用します。しかし、アップロードされた画像が正しく取得されていないようです。また、ファイルがアップロードされていない場合、デフォルトの画像はサーバーから渡されません。これらのエラーが発生しています：

2番目の画像をデフォルトとして指定すると、機能します。しかし、誰かがファイルをアップロードすると、アップロードされたものではなく、デフォルトのみが取得されます。基本的に、ここには2つの問題があります。

  1. アップロードされた画像が適切に渡されていない/アップロードされていない
  2. デフォルトの画像がサーバーから正しく取得されていません

私を助けてください。どうすればいいのかわからない。私は投稿を読んだことがありますが、ほとんど同じですが、役に立ちませんでした。事前にどうもありがとう！

コードで主な 2 つの変更を行うようにしてください。

  1. コードを if(isset($_FILES['file']['tmp_name'])){ に置き換えます if($_FILES['file']['tmp_name']!=""){

  2. デフォルトの画像からパスを削除: $uploadFilename = 'def_img.jpg';

私はそれが正常に動作することを試みました。デフォルトの画像とアップロードされた画像の両方をさらに処理できるようにテストした完全なコード。
