Question

我正在尝试从db为用户创建一个新的目录，这样他们就可以将文件上传到他们自己的目录中，并使我可以轻松管理他们的文件。如果有人能指出我正确的方向，我将不胜感激。欢呼声。

<html>
<head>
  <meta charset="UTF-8" />
  <title>Multiple File Upload</title>
    <link href="./style.css" rel="stylesheet" type="text/css">
    <script>
     function myFunction(file)
     {
      if(file.files.length>10)
      {
        alert("Maximum 10 files");
        document.getElementById("file").value='';
      }
     }
    </script>
</head>
<body>

<form action="" method="post" enctype="multipart/form-data" class='frms upload' id="upload" name="form1">
    <fieldset>
    <legend>Upload files</legend>
        <input type="file" id="file" name="files[]" multiple="multiple" required='required' onchange="myFunction(this)"/>

        <input type="submit" value="Upload" />

这是php文件，它将上传文件夹/ uploads / username中的所有文件。您可以使用此...并且为了在表格中显示文件，您可以使用ajax发布请求进行前端处理。

$username = $_GET['username'];

$target_dir = "../uploads/" . $username . "/";
if (!file_exists($target_dir)) {
    mkdir($target_dir, 0777, true);
}
$files1 = scandir($target_dir);
$files2 = scandir($target_dir, 1);

print_r($files1);
print_r($files2);

$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
echo $target_dir . "</br>";
echo $target_file . "</br>";
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}
// Check if file already exists
if (file_exists($target_file)) {
    echo "Sorry, file already exists.";
    $uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 500000) {
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
    $uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
        header("Location: ../../pages/edit-user.php?p=" . $plate_num);
        // echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}

?>
