PHP文件上传不起作用

Question

I'm trying to upload files to my server but it doesn't work at all. 我正在尝试将文件上传到我的服务器，但是根本不起作用。 Here is test code: 这是测试代码：

<?php
echo count($_FILES['upload']['name']);
?>

<!DOCTYPE html>
<html>
<body>

<form action="" method="POST" enctype="multipart/form-data">
    <input name="upload[]" type="file" accept=".mp3" multiple="multiple" />
    <br>
    <input type="submit" value="Upload">
</form>

</body>
</html>

It always prints 0 , file upload is enabled on my server. 它始终打印0 ，在我的服务器上启用了文件上传。

Answer 1

The problem is that you're not counting the $_FILES['upload'] . 问题是您没有计算$_FILES['upload'] 。

Simple fix for your problem 简单解决您的问题
Use: 采用：

echo count($_FILES['upload']);

Instead of: 代替：

echo count($_FILES['upload']['name']);

Edit: Remove [] from the input's name. 编辑：从输入名称中删除[] 。

Answer 2

  <?php
  echo count($_FILES['upload']);//only this modified//

  <body>
       <form action="" method="POST" enctype="multipart/form-data">
            <input name="upload[]" type="file" accept=".mp3" multiple="multiple" />
            <br>
            <input type="submit" value="Upload">
  </form>

  </html>
