ファイルを Web サーバーにアップロードし、アップロードするファイルを選択するために使用するフォームの下に出力メッセージを表示するスクリプトを作成するよう依頼されました。出力メッセージの表示に問題があります。関連する HTML フォームと JavaScript は次のとおりです。

<script type="text/javascript">
$(function() {
$('#fileuploader').submit(function(e) {
    e.preventDefault(); // e.preventDefault() for prevent form submisson with page reload
    $.ajax({
        type: "POST",
        url: "genericuploader.php",
        data: dataString,
        cache: false,
        success: function(html) {
            $("#message_post").prepend(html);
            close_box();
        }
    });

});
});
</script>

<form id="fileuploader" action="genericuploader.php" method="post">
        Select a file to upload: <input name="uploaded" type="file" /><br />
        <select name='department'>
            <option value="0">Select a Department</option>
            <option value="D1">Department 1</option>
            <option value="D2">Department 2</option>
            <option value="D3">Department 3</option>
            <option value="D4">Department 4</option>
            <option value="D5">Department 5</option>
            <option value="D6">Department 6</option>
        </select> <br>
    <input type="submit" value="Upload" />
    </form>
    <div id="message_post"></div>

この手法を使用して、バックグラウンドでファイルのアップロードを行うことができます。apc を使用します。
