Does anyone know of a way to get the file to download and give me the percentage of the file downloaded or even the filesize of the local copy every couple seconds or so? http://pear.php.net/package/HTML_Progress -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] progress bar for use with PHP uploads
Greetings Can anyone point me in the direction of a Javascript code snippet that would display a progress bar for a PHP upload? I'm sure it can be done that way, but honestly, I lack the Javascript skills to make it happen Any and all help would be appreciated. Thanks. Kenn

If I understood you correctly you want to accomplish something like
a) you have a file upload form
b) user clicks upload, and a progress meter is displayed
c) when the upload is done, the progress meter will be at 100% and vanish
or tell finished or something like that
I'm afraid this cannot be done very easily. What you'd need to know at the
moment the user clicks on upload would be the actual filesize, and the
average transmission speed so you can estimate the pace to go from 0 to
100. And, you need both values at the client's, a server side script is not
yet active at this time.
I'd suggest to take the easy road (seen on a couple of other sites)...
Create an animated gif with a progress bar constantly scrolling. In your
form's onSubmit() method (at the client's side!), do a window.open() with
the appropriate parameters to generate a small window without any controls,
sized sufficiently to just contain this gif.
The URL of this popup would be a PHP script (with the same session ID of
the uploader) which would basically do this:
if (!$_SESSION['popup_opened']) {
$_SESSION['popup_opened'] = true;
send_popup_html();
}
elseif (!$_SESSION['xmit_done'])
header('HTTP/1.0 204 No Content');
else send_close_html();
send_popup_html would add a header to refresh the popup:
header('Refresh: 1;
URL=http://'.$_SERVER['SERVER_NAME'].$_SERVER['PHP_SELF']?SID);
send_close_html would simply send html like
body onload='window.close();'
I hope you get the idea... Basically the crucial stuff is the refresh
header for the popup url that causes the client to _try_ to refresh every
second. As long as the transfer is not finished, the popup script simply
replies with 204 No Content, so the browser would change nothing with the
popup. When the upload is eventually finished, the refresh request
succeeds, but the only stuff the client receives is a javascript closing
the popup...

Re: [PHP] progress bar for use with PHP uploads
There's no way to know the percentage of the file that's uploaded, so you can't have a true progress indicator. You could just use a little popup that shows a 'wait, we're doing something' graphic that the following page closes when it loads. ---John Holmes... - Original Message - From: Kenn Murrah [EMAIL PROTECTED] To: php list [EMAIL PROTECTED] Sent: Tuesday, November 12, 2002 11:27 AM Subject: [PHP] progress bar for use with PHP uploads Greetings Can anyone point me in the direction of a Javascript code snippet that would display a progress bar for a PHP upload?

Re: [PHP] Progress bar for uploading files
Actually, I don't think you can make a progress bar function correctly for a file upload. The file is uploaded before control is ever given to the script. - Original Message - From: Oscar F [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, October 16, 2002 1:17 PM Subject: [PHP] Progress bar for uploading files Hello, I'm working on a file uploading script, but I need to know if there is a way to know what's the progress of the file, so I can make la a progress bar?..

[PHP] progress bar for a server side process
hi there i have created a script to regenerate thumbnails for a photo gallery , i have changed my code to use gd true color although it takes forever now , i have it generating 20 at a time then doing the rest but still takes forever , i know its impossible to generate a true progress bar for image uploads via a browser but how about server side processes ? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] progress bar for a server side process
I've got a nice progress bar with this code:
for($i=0;$i10;$i++) {
flush();
sleep(1);
echo 'img src=img.gif width=20 height=20 border=0 alt=X';
}
But read manual for the flush() function.

I was spidering remote sites and to get user's data and store in a database and the user could not continue until the spider spun it's web. I accpeted the data I needed and then returned a page with the HTTP-REFRESH tag in it with something like this meta http-equiv=Refresh content=10; URL=http://yoursite.com/verify_upload?process_id=Xamp;action=check_uploadamp;timer=X So it refreshes every 10 seconds and checks to see if process X has finished, if so then redirect to the next step, if not then just return but upgrade the timer so you can increase your counter (perhaps a percentage in a table cell).

[PHP] progress bar
Hi, I would like to add a progress bar to an installtion program I'm writing in PHP. I basically have one function that I call, it takes about 30 seconds or so to finish executing... I haven't done such a thing before. Can anyone plese suggest me some ideas... Many Thanks Serdar -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] progress bar
Unless you can break the process up into a series of smaller process' (and use meta refresh's or javascript redirects to step through each process), you're out of luck... because the browser can't possibly know what's happening in the background on the server. For a cheap and nasty solution, how about an animated GIF that lasts about 40 or 50 seconds? It can start empty, and animate up to full... as long as the process finishes before the GIF, all will be well.

RE: [PHP] progress bar
Hi! Well i suppose flush() is useful in your case, flush out the output whenever it is called, and not when the page is fully generated (the usual case)! Sou you might to sth like this: - Print 1/4 of the progress bar - flush - wait some time - print 2/4 of the progress bar - flush i don't know if it works, but that's the way it'd do it ;) - Tom -Original Message- From: Serdar Sokmen [mailto:[EMAIL PROTECTED]] Sent: Monday, August 12, 2002 12:06 PM To: [EMAIL PROTECTED] Subject: [PHP] progress bar Hi, I would like to add a progress bar to an installtion program I'm writing in PHP.

To make it look that little bit nicer, you could use flash to display the bar... but I think that make take a little longer than you'd like for development. Hi!

I agree with the flush() solution.
