php 错误数组不工作

Question

我正在为申请人创建一个简历上传门户，但无法获取要上传的文件。通过额外的测试，我相信问题出在我的错误数组上。当我故意制造错误时（通过不输入应聘者申请的职位）刷新页面后错误数组不显示错误，post 提交。我找不到任何错误类型，也不确定从这里去哪里。我认为新鲜的眼光和经验将帮助我解决这个问题。任何帮助将不胜感激！

表单提交页面：

    ?php require_once("CareerFunctions.inc");
    $Server= "http://localhost/";
    ?>
    <!doctype html>
    <html>
    <head>
    <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
    <script type="text/javascript" src="register.js"></script>
    <script src='https://www.google.com/recaptcha/api.js'></script>
    <link rel="stylesheet" type="text/css" href="form.css"></link>
    <title>Career Registration</title>
    </head>
    <body>
    Please upload your resume or skip this page and enter it manually.
    <br>
    <br>

    <form action="resumeupload.php" method="post" 

        enctype="multipart/form-data"> 

      <div>
    Select file to upload(Only pdf, Microsoft Office, & Open Office documents are allowed):
    <br>
        <br>
    <div id="ErrorDiv">
    <?php
    if (isset($_SESSION['Error']) && isset($_SESSION['FormAttempt'])){
    unset($_SESSION['FormAttempt']);
    print "Errors Encountered";}
    if (isset ($_SESSION['Error']) && is_array($_SESSION['Error']) && $_SESSION['Error']!==""){
    foreach ($_SESSION['Error'] as $Error) 
    {
    echo "<br>\n" .$Error;
    } //end foreach
    } //end if
    ?>
    </div>
       <br><br>
          <input type="file" id="Upload" name="Upload">
          <br>
          <br>
            Position you are applying for:
            <br>
            <br>
            <input type="text" id="Position" name="Position">
            <br>
            <br>
                <input type="hidden" name="MAX_FILE_SIZE" value="350000">
            </div>
            <input type="submit" value="Submit" name="submit" >
          <br>
        <br>
      </div> 
      <a href="<?php echo $Server?>CareerRegisterManualResume.php">Skip</a>
          <br>
            <div>
    </form>
    </body>
    </html>

表单处理页面（我只包含了错误生成部分）：

<?php
require_once('CareerFunctions.inc');
if (!isset($_POST['Submit'])) {
    die(header("Location:CareerRegisterResume.php"));
$_SESSION['FormAttempt'] = true;
if (isset($_SESSION['Error'])) {
unset($_SESSION['Error']);
}
}
$_SESSION['Error']= array();
if (!preg_match('/\.pdf$/i',$_FILES['Upload']['type']) ||
    !preg_match('/\.doc$/i',$_FILES['Upload']['type']) ||
    !preg_match('/\.docx$/i', $_FILES['Upload']['type'])||
    !preg_match('/\.odt$/i',$_FILES['Upload']['type']))
{$_SESSION['Error'][] = "File type must be a pdf (.pdf), Microsoft Office (.doc or .docx), or Open Office (.odt)";
}
if ($_FILES['Upload']['size'] > '350000')
{$_SESSION['Error'][] = "File is too large for upload!";}
if ($_FILES['Upload']['size'] == '0' || $_FILES['Upload']['size'] = '' || !isset($_FILES['Upload']['size']))
{$_SESSION['Error'][] = "Please select a file for upload";}
if ($_POST['Position']= '' || !isset($_POST['Position']))
{$_SESSION['Error'][]= "Please enter the position you are applying for.";}
if (isset($_FILES['Upload']['error']) && $_FILES['Upload']['error'] > '0' || $_FILES['Upload']['error'] !== '')
{$_SESSION['Error'][]= "There was an issue uploading the file to the server";}

if (count($_SESSION['Error']) > '0')
{die(header("Location: CareerRegisterResume.php"));}

if(UploadResume($_POST)) {
die(header("Location: ApplySuccess.php"));}
else {
error_log("Problem uploading resume: {$_FILES['Upload']['name']}");
$_SESSION['Error'][] = "Problem Uploading Resume";
die(header("Location: CareerRegisterResume.php"));
}
