hi!
i want to create a remote uploader...
i wrote something that you see below:
PHP Code:
<html>
<head>
<title>upload.php</title>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script language='javascript' type="text/javascript">
alert('2e2e');
function do_upload()
{
alert('it works...!');
var source_url=document.getElementById('url').value;
//ajax request for remote upload
$.ajax({
type: "POST",
url: "http://ektoplazm.ir/files/upload2.php",
data: { url: source_url, submit: "Upload" }
}).done(function( msg ) {
alert( "Data Saved: " + msg );
});
//continue : update upload status
setInterval('update_upload_status()',512);
}
function update_upload_status(){
alert('upload is starting...');
var source_url=document.getElementById('url').value;
var destination_url=source_url.substring(source_url.lastIndexOf('/')+1);
var sfilesize;
var dfilesize;
var request;
request = $.ajax({
type: "HEAD",
url: $("#"+source_url).val(),
success: function () {
sfilesize=request.getResponseHeader("Content-Length"));
}
request = $.ajax({
type: "HEAD",
url: $("#"+destination_url).val(),
success: function () {
dfilesize=request.getResponseHeader("Content-Length"));
}
var progress=dfilesize/sfilesize*100;
if (progrss==100){
document.getElementById('progress').innerhtml='done!';
}else{
document.getElementById('progress').innerhtml=progress;
}
}
</script>
</head>
<body>
<form action='' method="post">
<input name="url" size="50" />
<input name="upload" type="button" value='upload' onclick="javascript:do_upload();" />
</form>
<p id='progress'>progress</p>
</body>
</html>
<?php
// maximum execution time in seconds
set_time_limit (24 * 60 * 60);
if (!isset($_POST['submit'])) die();
// folder to save downloaded files to. must end with slash
$destination_folder = '';
$url = $_POST['url'];
$newfname = $destination_folder . basename($url);
echo $url;
$file = fopen ($url, "rb");
if ($file) {
$newf = fopen ($newfname, "wb");
if ($newf)
while(!feof($file)) {
fwrite($newf, fread($file, 1024 * 8 ), 1024 * 8 );
}
}
if ($file) {
fclose($file);
}
if ($newf) {
fclose($newf);
}
?>
i don't know why this code does not work correctly. javascript section does not run.
