我有一個網站,允許使用HTML5多種設置上傳多個文件。我使用PHP腳本來驗證文件並上傳它們。僅使用PHP和HTML/CSS我想爲正在上傳的文件(或文件)創建一個進度條。我怎樣才能做到這一點?我知道PHP可以使用APC獲取文件上傳信息,但是如何合併多個文件上傳?帶進度條的PHP和HTML多文件上傳
<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;
}
}
?>
<!-- CONTINUE WITH HTTP FORM//-->
<body>
<div id="banner_left">

Choose file(s) to upload (Max 500MB): <input name="rye_file[]" type="file" id="multiple" multiple />
<input type="submit" name="submit" value="Upload" />
</form>
我感謝您的幫助,
附:我寧願避免使用JavaScript,因爲我對它不夠熟悉。首選PHP和HTML/HTML5。
這裏是一個jQuery插件,支持多文件上傳和progressbars你可能會發現它有用。 http://www.dropzonejs.com/ –
我不認爲沒有JavaScript就沒有這種可能。你需要操縱你的DOM而不刷新頁面(IE取消文件上傳) –
進度條需要JS。另一個插件,你可以使用:http://blueimp.github.io/jQuery-File-Upload/ – AzDesign
