Question

我想在dropzone中删除文件后将文件拖到放置区域，然后必须附加HTML文件上传控件。并在点击提交按钮上传文件。

<form name="form1" method="post" enctype="multipart/form-data" action="index.php">
    <div id="dropContainer" style="border:1px solid black;height:100px;width:100px;">
        Drop Here
    </div>
    Should update here: <input type="file" name="fileInput" id="fileInput" />
    <input type="submit" name="submit" value="submit"/>
</form>

Answer 2

我想将附件说明字段验证为必填字段，不要上传文件。单击提交按钮后，仅上载文件并验证所需字段。

<form name="form1" method="post" enctype="multipart/form-data" action="index.php">
    <div id="dropContainer" style="border:1px solid black;height:100px;width:100px;">
        Drop Here
    </div>
    <div>
      Attachment Description : <input type="text" name="description" id="description" required>
    </div>
    <div>
      Should update here: <input type="file" name="fileInput" id="fileInput" />
    </div>
    <input type="submit" name="submit" value="submit"/>
</form>
