Question

我创建了一个成功的文件上传系统。

但如何将上传的文件移动到具有随机名称的文件夹？（当前时间）

的index.php：

<!doctype html>
<body>
   <form action="file-up.php" method="post" enctype="multipart/form-data">
        <table>
            <tr><td>File:</td><td><input type="file" name="myfile"></td></tr>
            <tr><td>&nbsp;</td><td><input type="submit" value="Upload"></td></tr>
        </table>
    </div>
    </form>
</body>
</html>

文件up.php：

<?php

$time = new DateTime();
$time->format('YmdHis'); 


$upload_dir = "uploads/";// . $time;
if (isset($_FILES["myfile"])) {
    if ($_FILES["myfile"]["error"] > 0) {
        echo "Error: " . $_FILES["file"]["error"] . "<br>";
    } else {
        move_uploaded_file($_FILES["myfile"]["tmp_name"], $upload_dir . $_FILES["myfile"]["name"]);
        echo "Uploaded File: " . $_FILES["myfile"]["name"];
    }
}
?>

Answer 1

试试此工作代码

    <?php

$time = new DateTime();
$time->format('YmdHis'); 


//$upload_dir = "uploads/";// . $time;
$folder_name=date('mds');
$new_folder=mkdir($folder_name, 0777, true);
if(file_exists($new_folder)){

  echo "Folder already exist";
}
$upload_dir = $folder_name.'/';
if (isset($_FILES["myfile"])) {
    if ($_FILES["myfile"]["error"] > 0) {
        echo "Error: " . $_FILES["file"]["error"] . "<br>";
    } else {
        if(move_uploaded_file($_FILES["myfile"]["tmp_name"], $upload_dir. $_FILES["myfile"]["name"])){
        echo "Uploaded File: " . $_FILES["myfile"]["name"];
      } else {
        echo $new_folder .'/'. $_FILES["myfile"]["name"];
        echo "Folder created file not uploaded";
      }

    }
}
?>

Answer 2

检查date()

后，您可以使用mkdir()功能和if directory already exists功能

$upload_dir = "uploads/".date('YmdHis');
if(!is_dir($upload_dir))
{
    mkdir($upload_dir);
}
if (isset($_FILES["myfile"])) {
    if ($_FILES["myfile"]["error"] > 0) {
        echo "Error: " . $_FILES["file"]["error"] . "<br>";
    } else {
        move_uploaded_file($_FILES["myfile"]["tmp_name"], $upload_dir . $_FILES["myfile"]["name"]);
        echo "Uploaded File: " . $_FILES["myfile"]["name"];
    }
}

文件上传到当前时间的文件夹
