Question

我正在尝试组合多个表单元素。我有2个按钮，1个tex tbox和1个上传框以及1个下拉菜单，如下所示：

upload.php

因此，用户可以选择要上载的目录，通过单击“创建”按钮和上载文件来创建新目录。但是，使用我当前的代码，它不起作用（文件上传到默认目录）。

这是代码：

<?php
  include("login.php");

?>

</head>

<div id="wrapper">

    if ($isLoggedin === false) {

        echo "<p align='right'>You are not logged in.</p>";
        echo "<b><a href='registration.php'>Register</a></b>";

我想让用户在上传之前创建一个目录，然后从下拉列表中选择一个选项来选择要上传的目录。

我该怎么做？

Answer 1

您的表单标记在选择框之前结束，因此将其移到选择框下方，您应该获得与所选上传目录相关的帖子值。
