Uploadify からサーバーに送信されたファイル情報を処理するかなり単純なスクリプトがあり、サムネイルの作成以外はすべて機能します。私の間違いがどこにあるのか誰にもわかりますか？

前もって感謝します！コリン

私はあなたのコードをテストしました、そしてそれは原因のいくつかの変更で動作します

使用済み

$targetFolder = realpath('/temp'); // Relative to the root
$thumbsFolder = realpath('/temp/thumbs/'); // Relative to the root

でエラーもあります$extension = end(explode(".", $_FILES['Filedata']['name']));

に置き換えます

  $extension = $fileParts ['extension'];

完全なコード

<?php
session_start ();
//include "../_db.inc";

    $targetPath = $_SERVER ['DOCUMENT_ROOT'] . $targetFolder;
    $yourid = 2 ;//( int ) $_POST ['yourid'];

    $fileParts = pathinfo ( $_FILES ['Filedata'] ['name'] );

        } else {

        list ( $width, $height ) = getimagesize ( $tempFile );

        $newwidth = 50;

        $thumbname = $targetThumb;

        if (file_exists ( $thumbname )) {
            unlink ( $thumbname );
        }

        imagejpeg ( $tmp, $thumbname, 100 );

        imagedestroy ( $src );
        imagedestroy ( $tmp );

        move_uploaded_file ( $tempFile, $targetFile );
        echo '1';
    } else {
        echo 'Invalid file type.';
    }

?>


<form method="post" target="_self" enctype="multipart/form-data">
    <input type="file" name="Filedata" id="file" /> <input name="submit"
        type="submit" value="submit" />

結論..この問題はあなたのファイルパスのようであり、いくつかのphp未定義エラーは次のようにエラーを出力します

 error_reporting(E_ALL);
 ini_set('display_errors','On');
