我无法让图像上传功能在以下代码上工作，并出现以下错误消息：

'第 135 行的脚本'/database.php' 中发生错误：未定义的索引：图像'

这是这部分： 'if (is_uploaded_file ($_FILES ['image']['tmp_name'])) {'

我之前做过一些 php/mysql 表单，但这是我第一次尝试使用图像上传。如果可能的话，我正在使用仅允许 pdf 和 jpeg 并将上传限制为 1.5 兆的表单。

表格的其余部分工作正常，除此之外，我已将服务器上上传文件夹上的 CHMOD 更改为 777。有什么想法或建议吗？

你<form>没有enctype属性。

<form action="logsales.php" method="post">

它需要是：

<form action="logsales.php" method="post" enctype="multipart/form-data">

没有它，您的浏览器不知道如何将文件发送到您的服务器，因此没有enctype，它将无法工作。更多信息可在W3获得。

还要在您的上方添加另一个 if 条件，if (is_uploaded_file ($_FILES ['image']['tmp_name']))如下所示：

if (isset($_FILES['image']) && $_FILES['image']['tmp_name'] != ''){
  if(is_uploaded_file($_FILES['image']['tmp_name'])){  
  ................your logic here.............
  }
}
