PHP文件上传不起作用

Question

I'm working on a web application in php that allows users to upload files with a specified structure (file type could be cvs or excel sheets) and the app will extract data from the files and insert them into a database. 我正在使用php中的Web应用程序进行工作，该应用程序允许用户上传具有指定结构（文件类型可以是cvs或excel表）的文件，并且该应用程序将从文件中提取数据并将其插入数据库中。

I can't get my app to upload files and I've been trying for 2 days, I checked the php.ini for max upload size ,max post size , file uploads on, temp directory set to /tmp which is accessible by all users. 我无法让我的应用上传文件，并且已经尝试了2天，我检查了php.ini以获取最大上传大小，最大发布大小，文件上传位置，设置为/ tmp的temp目录，所有人均可访问用户。

I also checked the syntax of php and html and made sure I was using the right encoding type, I also checked the permissions of the upload directory but the _FILES variable is always empty, note : my web server is hosted on amazon ec2 running Ubuntu 14.04 LTS. 我还检查了php和html的语法，并确保使用正确的编码类型，还检查了上传目录的权限，但_FILES变量始终为空，请注意：我的Web服务器托管在运行Ubuntu 14.04的Amazon ec2上LTS。

here's one of the codes I tried and it's output: 这是我尝试过的代码之一，它的输出是：

<?php
        echo $_FILES['file']['error'];
        print_r($_FILES);
        echo $name = $_FILES['file']['name'];
?>

<html>
<header>
<title> Test Page</title>
</header>
<body>
<form action="Test.php" method="POST" enctype="multipart/formdata">
        <input type="file" name="file" id="file" /><br><br>
        <input type="submit" value="submit" />
</form>
</body>
<html>

and the outputted echo is only Array ( ) whether I upload a file or not. 无论我是否上传文件，输出的回声只是Array（）。

anyone faced something like this before ? 有人遇到过这样的事情吗？

<?php
     if ($_SERVER["REQUEST_METHOD"] == "POST") {
        session_start();

        $file_tmp= $_FILES['image']['tmp_name'];
        header("Test.php");
     }
 ?>

       <form action="form-validation" method="POST" enctype="multipart/form-data" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>" >

        <div class="form-row form-input-name-row">

          <div class="form-row form-input-name-row">
              <img id="blah" src="#" alt="your image" style="width: 100px; display: none; margin-bottom:10px;" />

       </form>
<script>

function readURL(input) {
    if (input.files && input.files[0]) {
        var reader = new FileReader();
        reader.onload = function (e) {
            $('#blah').show().attr('src', e.target.result);
        }
        reader.readAsDataURL(input.files[0]);
