Question

我已经在网站上工作了一段时间，我在这里使用的代码大约一个月前工作，然后我尝试将文件放在子文件夹中，并重定向move_uploaded_file函数，但它没有似乎工作。具体来说，两者都是：

if((!empty($_FILES["uploaded_letter"])) &&  ($_FILES['uploaded_letter']['error'] == 0))

和

if((!empty($_FILES["uploaded_list"])) && ($_FILES['uploaded_list']['error'] == 0))

语句返回false。如果有人可以请求帮助，那将是非常棒的！谢谢！

Answer 1

最好是要上传多个文件以使用数组命名文件，例如add newsletter: <input name="uploaded_letter[]" type="file" /> add list: <input name="uploaded_letter[]" type="file" />然后您可以在目标页面中使用foreach

Answer 2

使用此，

if((!empty($_FILES["uploaded_letter"]["name"]))
{
    // Your Procedures
}

if((!empty($_FILES["uploaded_list"]["name"]))
{
  // Your Procedures
}

Answer 3

我认为你应该在upload（）中使用if和else if条件，如：

function upload(){
        if((!empty($_FILES["uploaded_letter"])) && ($_FILES['uploaded_letter']['error'] == 0)) {
            //your code......
        }
        //missing elseif statement instead of if

        elseif ((!empty($_FILES["uploaded_list"])) && ($_FILES['uploaded_list']['error'] == 0)) {
            //your code....

      else {
                echo "Error: file is too large";
            }
        } 
        else {
            echo "Error: No file uploaded";
        }
    }
