Question

我有一个网站，允许使用HTML5多重设置上传多个文件。我使用PHP脚本来验证文件并上传它们。仅使用PHP和HTML / CSS我想为正在上传的文件（或文件）创建进度条。我怎样才能做到这一点？我知道PHP可以使用APC来获取文件上传信息，但是如何将这些信息合并到正在上传的多个文件中？

<html>
<head>
<style type="text/css" media="screen">
     div#banner_left {
       position: absolute;
       top: 0%;
       left: 0%;
       width: auto;
     }
     div#banner_right {
       float: right;
       width: auto;
     }
    </style>
<link rel="stylesheet" type="text/css" href="/css/structure.css">
</head>
<?php
echo "<div id='banner_right'>Welcome ";
echo $_SESSION['myusername'];
echo "<br><form action='/logout.php'>";
echo " <input type='submit' value='Logout' style='width:216px; font-size: 15px;'>";
echo "</form>";
echo "</div><br><br>";
?>


<!-- FILE UPLOAD SCRIPT//-->

<?php
if(isset($_POST['submit']))
{
$subject_list = $_POST['subject_list'];
$document_type = $_POST['document_type'];
$uploaddir = "/var/www/rye-high-website/Rye High/uploads/$subject_list/$document_type";
$files=array();
$fdata=$_FILES['rye_file'];
if(is_array($fdata['name'])){
 for($i=0;$i<count($fdata['name']);++$i){
  $files[]=array(
   'name'     => $fdata['name'][$i],
   'tmp_name' => $fdata['tmp_name'][$i],
  );
 }
}
else $files[]=$fdata;

foreach ($files as $file) {
  // uploaded location of file is $file['tmp_name']
  // original filename of file is $file['name']
  $move_file = move_uploaded_file($file['tmp_name'], "$uploaddir/".$file['name']);
}

if ($subject_list == "None") {
   echo '<br><div class="alert">Please Pick A Course Code</div>';
}
if ($document_type == "None"){
   echo  '<br><div class="alert">Please Pick A Document Type</div>';
}
if($move_file){
   echo  '<br><div class="info">File is valid, and was successfully uploaded to: $subject_list folder</div>';
  }
else {
     echo '<br><div class="alert">Upload Failed</div>';
     echo $move_file;
 }
}

?>

感谢您的帮助，

P.S。我宁愿避免使用javascript，因为我对它不熟悉。 PHP和HTML / HTML5首选。
