问题描述
我一直在寻找答案很多天。如何将多个文件上传到新创建的目录。如果您查看 file_upload.PHP，您会发现两个 $upload_dir 变量。因此，让我们先将 $upload_dir 称为直接文件夹，然后将 $upload_dir 称为 make 目录。简单
因此，当我选择第一个 $upload_dir 时，它会将所有文件直接上传到文件夹中，而当我选择第二个 $upload_dir 时，它会创建一个随机文件夹，但无法上传任何文件。>
我确实参考了这个 PHP - Upload multiple photos into newly created Directory 和 Multiple file upload and store them in a directory，但对我不起作用
index.PHP
<form action="file_upload.PHP" method="POST"
enctype="multipart/form-data">
<h2>Upload Files</h2>
<p>
Select files to upload:
<!-- name of the input fields are going to
be used in our PHP script-->
<input type="file" name="files[]" multiple>
<br><br>
<input type="submit" name="submit" value="Upload" >
</p>
</form>
file_upload.PHP
<?PHP
// session_start();
// Check if form was submited
if(isset($_POST['submit'])) {
// Configure upload directory and allowed file types
$rand_name = rand(1,10000);
// $upload_dir = 'C:/fileUpload/'.DIRECTORY_SEParaTOR;
// $permit = 0777;
$allowed_types = array('jpg','png','jpeg','gif');
$upload_dir = mkdir('C:/fileUpload/'. $rand_name .'/'.DIRECTORY_SEParaTOR,0777);
// Define maxsize for files i.e 10MB
$maxsize = 10 * 1024 * 1024;
// Checks if user sent an empty form
if(!empty(array_filter($_FILES['files']['name']))) {
// Loop through each file in files[] array
foreach ($_FILES['files']['tmp_name'] as $key => $value) {
$file_tmpname = $_FILES['files']['tmp_name'][$key];
$file_name = $_FILES['files']['name'][$key];
$file_size = $_FILES['files']['size'][$key];
$file_ext = pathinfo($file_name,PATHINFO_EXTENSION);
// Set upload file path
$filepath = $upload_dir.$file_name;
// Check file type is allowed or not
if(in_array(strtolower($file_ext),$allowed_types)) {
// Verify file size - 10MB max
if ($file_size > $maxsize)
echo "Error: File size is larger than the allowed limit.";
// If file with name already exist then append time in
// front of name of the file to avoid overwriting of file
if(file_exists($filepath)) {
$filepath = $upload_dir.time().$file_name;
if( move_uploaded_file($file_tmpname,$filepath)) {
echo "{$file_name} successfully uploaded <br />";
}
else {
echo "Error uploading {$file_name} <br />";
}
}
else {
if( move_uploaded_file($file_tmpname,$filepath)) {
echo "{$file_name} successfully uploaded <br />";
}
else {
echo "Error uploading {$file_name} <br />";
}
}
}
else {
// If file extention not valid
echo "Error uploading {$file_name} ";
echo "({$file_ext} file type is not allowed)<br / >";
}
}
}
else {
// If no files selected
echo "No files selected.";
}
}
?>
请帮忙！

解决方法
mkdir 返回一个布尔值（真或假），而不是创建的目录路径。
您可能想在 $upload_dir 中定义路径，但不想将 mkdir 的结果分配给它：
$upload_dir = 'C:/fileUpload/'. $rand_name .'/';
if (mkdir($upload_dir,0777)) {
//process images
}
