PHP问题（文件上传）
[英]PHP Problems (file uploading)
问题描述
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就起作用了，然后我尝试将文件放在子文件夹中，并重定向move_uploaded_file函数，但它似乎没有用。 具体来说，两个都：
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。 如果有人可以帮助您，那就太好了！ 谢谢！

最好有多个文件要上传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" />则可以在目标页面中使用foreach

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

我认为您应该在上载条件中使用if和else if条件，例如：
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";
}
}
