Question

我想在我的系统上创建一个上传功能，但即使我还没有选择文件，网页上也会显示一条消息。谁能帮我？这是我的代码：

附件：

                <td><form action="upload_file.php" method="post" enctype="multipart/form-data">
                <input type="file" name="reservation_Attachment" size="50" />
                <br />
                <input type="submit" value="Upload" />
                </form>

                <?php
                 $targetfolder = "attachment/";
                 $targetfolder = $targetfolder . basename( $_FILES['reservation_Attachment']['name']) ;
                 if(move_uploaded_file($_FILES['reservation_Attachment']['tmp_name'], $targetfolder))
                 {
                 echo "The file ". basename( $_FILES['reservation_Attachment']['name']). " is uploaded";
                 }
                 else {
                 echo "Problem uploading file";
                 }
                 ?>

                 <?php
                 $targetfolder = "attachment/";
                 $targetfolder = $targetfolder . basename( $_FILES['reservation_Attachment']['name']) ;
                 $ok=1;
                $file_type=$_FILES['reservation_Attachment']['type'];
                if ($file_type=="application/pdf" || $file_type=="image/gif" || $file_type=="image/jpeg") {
                 if(move_uploaded_file($_FILES['reservation_Attachment']['tmp_name'], $targetfolder))
                 {
                 echo "The file ". basename( $_FILES['reservation_Attachment']['name']). " is uploaded";
                 }
                 else {
                 echo "Problem uploading file";
                 }
                }
                else {
                 echo "You may only upload PDFs, JPEGs or GIF files.<br>";
                }
                ?></td>
            </tr>

以下是错误：

注意：未定义索引：reservation_Attachment in   第210行的C：\ xampp \ htdocs \ sportvenuereservation \ reservation_form.php

注意：未定义索引：reservation_Attachment in   第211行的C：\ xampp \ htdocs \ sportvenuereservation \ reservation_form.php   问题上传文件注意：未定义的索引：reservation_Attachment   在C：\ xampp \ htdocs \ sportvenuereservation \ reservation_form.php上线   222
