在文件上传PHP中找不到对象[关闭]

Question

我正在尝试上传文件，但我不断收到发送到未找到对象的页面错误 404。

我猜这是因为我的路径目录错误，并且在 'localhost' 和 C:\xampp\htdocs\PHP 之间存在错误

提前致谢

我的 PHP 代码

<?php

$target_dir = "..\upload";
$target_file = $target_dir.basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$uploadError = "Error";
$fileType = pathinfo($target_file,PATHINFO_EXTENSION);

    if(isset($_POST["submit"])) {
    $uploadOk = 1;
  }


    if (file_exists($target_file)) {
    $uploadOk = 0;
    $uploadError = "Sorry, file already exists.";}

    if ($_FILES["fileToUpload"]["size"] > 100000) {
    $uploadOk = 0;
    $uploadError = "Sorry, your file is too large.";}

    if($fileType != "txt" ) {
        $uploadOk = 0;
        $uploadError = "Sorry, only NOW TXT files are allowed.";}

    if ($uploadOk == 0) {
        echo $uploadError;} else {
    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
        echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
}}?>

我的 HTML

<form action=".php" method="post" enctype="multipart/form-data"> Select image to upload: <input type="file" name="fileToUpload" id="fileToUpload"> <input type="submit" value="Submit" name="submit"> </form>

改变这个：

action=".php"

收件人：

action=""

（默认重定向到当前页面）

404 表示提交表单后未找到您重定向的页面。 “.php”的值不好。
