Help needed with MU Remote Upload Script

[TimeManx]

Hi guys, I need help with a Megaupload Remote Upload Script that I'm making.

 

There are 2 pages, upload.php & process.php.

 

So it works like this. I can enter many links in a textarea (since MU doesn't allow more than one link to be submitted at once on their site), process.php sends 5 of these links at once to upload.php with the use of Javascript.

 

upload.php submits the links to MU(with cURL) and also checks the upload status(this too with cURL). If an upload is completed, process.php sends out the next link to upload.php.

 

process.php

 

<script type = 'text/javascript'>

var rslinks = '';
var mulinks = '';
var linklist = '';

function ajaxRequest(){
var activexmodes = ["Msxml2.XMLHTTP", "Microsoft.XMLHTTP"];
if (window.ActiveXObject) {
	for (var i = 0; i < activexmodes.length; i++) {
		try {return new ActiveXObject(activexmodes[i]);}
		catch(e){}
	}
}

else if (window.XMLHttpRequest) return new XMLHttpRequest();

else return false;
}

function ajaxdata(filehost, urls) {
var http = new ajaxRequest();
var urls_array = urls.split(',');
var filtered_urls = new Array();			
for (i = 0; i < urls_array.length; i++) {
	if (filehost == 'mu')
		if (mulinks.indexOf(urls_array[i]) == -1)
			filtered_urls.push(urls_array[i]);
	else if (filehost == 'rs')
		if (rslinks.indexOf(urls_array[i]) == -1)
			filtered_urls.push(urls_array[i]);
}

final_urls = filtered_urls.length >= 5 ? filtered_urls.slice(0, 5).join(',') : filtered_urls.join(',');

So initially, the urls are passed to ajaxdata in process.php which sends 5 urls to upload.php. upload.php checks the megaupload page to see which urls have already been submitted. The ones which havent been submitted are submitted and the upload status for the already submitted urls are sent back to process.php which displays these stats in the browser. process.php checks each response to see if a url has finished uploading & if it is true for a url then the url is stored in mulinks and the next url is sent to upload.php.

 

 

So the problem that I'm facing is that some of the links get submitted twice or sometimes even thrice. It could be that I need to increase the time period between a link submission & the next AJAX request. I tried putting in sleep(8') in the 9th line from the end of upload2mu function in upload.php.

if (!empty($tobesubmitted)) {
postmu($tobesubmitted, $user_mu, $pass_mu, $mu_uppars);
sleep(;
}

But it didn't work. I really can't think of anything else.
