再会！

我将首先说我刚刚开始学习 PHP，所以请放轻松...

基本上，我有一个表单，允许用户上传 2 张图片（以及完成其他字段）。提交时，表单调用一个 PHP 文件（下面的代码），该文件基本上将详细信息添加到数据库并将图像上传到文件服务器。这对于我想要完成的工作来说很好。我遇到问题的地方是确认消息。

因为我有 2 个单独的上传字段，所以我基本上有 2 个 if 语句来确认这两个文件已正确上传。我想简化一下，所以我真的只需要显示 1 条确认消息。

关于如何简化这一点的任何想法？我认为如果两个文件都已成功上传，则代码将显示，如果是则回显“x”，否则回显“y”。我对 move_uploaded_file 函数不太熟悉，所以我不确定我是否可以在那里使用 AND 语句......任何想法将不胜感激。

//This is the directory where images will be saved
$target = "path/";
$target = $target . basename($_FILES[controlcreative][name]);
$target2 = "path/";
$target2 = $target2 . basename($_FILES[winnercreative][name]);

$pic=($_FILES['controlcreative']['name']);
$pic2=($_FILES['winnercreative']['name']);

$con=mysqli_connect();
// Check connection
if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }

$sql="INSERT INTO experiments (vertical, pagetype, pagename, primarykpitype, primarykpilift, primarysignificant, testobjective, takeawayone, optimizationtype, controlcreative, winnercreative)
VALUES
('$_POST[vertical]','$_POST[pagetype]','$_POST[pagename]','$_POST[primarykpitype]','$_POST[primarykpilift]','$_POST[primarysignificant]','$_POST[testobjective]','$_POST[takeawayone]','$_POST[optimizationtype]','$pic','$pic2')";

if (!mysqli_query($con,$sql))
  {
  die('Error: ' . mysqli_error($con));
  }
echo "1 record added";


//Writes the photo to the server
if(move_uploaded_file($_FILES[controlcreative][tmp_name], $target))
{

//Tells you if its all ok
echo "The file ". basename($_FILES[controlcreative][name]). " has been uploaded, and your information has been added to the directory";
}
else {

//Gives and error if its not
echo "Sorry, there was a problem uploading your file.";
}

//Writes the photo to the server
if(move_uploaded_file($_FILES[winnercreative][tmp_name], $target2))
{

//Tells you if its all ok
echo "The file ". basename($_FILES[winnercreative][name]). " has been uploaded, and your information has been added to the directory";
}
else {

//Gives and error if its not
echo "Sorry, there was a problem uploading your file.";
}


mysqli_close($con);

我会循环遍历$_FILES它可能会为您节省一些代码并设置错误标志

$error = false;
foreach($_FILES as $name => $file)
{
    $target = '/path/to/destination/' . $file['name'];
    if(!move_uploaded_file($file['tmp_name'], $target)) $error = true;
}

然后

if(!$error) echo 'All files uploaded';
