上传表格的正确方法

Question

我在尝试正确上传图像时遇到了问题，我感觉这是一个基本错误。问题是它似乎没有上传图像：

addimage.php

<?php

include('includes/session.php');

include('includes/header.php');

include('includes/class/class.form.php');

include('includes/class/class.image.php');

define("MAX_SIZE","1000000");

$formImageUpload = new Form('addimage.php', 'imageUpload', 'post','multipart/form-data', ''); //return CheckImage();

$Message = "";


if(isset($_POST["submit"])) {

    $formImageUpload->setStickyData($_POST);

    $formImageUpload->checkUpload("ImagePath","image/jpeg", MAX_SIZE);


    $formImageUpload->checkNotEmpty("ImageName");


    if($formImageUpload->getValid() == true){

        $AddImage = new Image();

        $AddImage->setImageName($_POST["ImageName"]);

        $AddImage->setImagePath($_POST["ImagePath"]);

        $AddImage->imageUpload();

        $AddImage->saveImage();

        $Message = "Thank You, Your Image Has Been Uploaded";

        print_r($_FILES);

        exit;

    } else {

        $Message = "Sorry You Have An Error Please Try Again";
    }

}

$formImageUpload->openFieldset();
$formImageUpload->makeInputBox('Image','ImageName','');
$formImageUpload->makeHiddenField("MAX_FILE_SIZE", MAX_SIZE);
$formImageUpload->makeUpLoadBox('Image Path',"ImagePath",'');
$formImageUpload->makeSubmitButton("submit","Image Upload");
$formImageUpload->closeFieldset();
?>

 <section class="left">

<h1  class="Heading">Add Image</h1>

    <p class="loginError"><?php echo $Message;?></p>

<?php echo $formImageUpload->getHTML(); ?>

</section> <!-- Section Left End -->

<section class="right">
    <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry.
    Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.
    It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

尝试进行测试，您只需：
var_dump($_FILES)
这是包含所有上传文件的全局数组。如果为空，请检查：

1. 临时目录的权限
2. 是否允许文件上传
3. 如果您的表单元素看起来（有点）像
