You can also store the progress in a session, rather than in a file.

You are right. My example will only work for a single client. and that can be solved using a token like you said. thanks.

Hi,

How would you adapt this to make the progress bar work for more than 1 client at a time. I think the way you have it, if a second client comes in while the first one is in the middle of the operation, the progress file will get stomped on by the two executing scripts and the progress returned may not always be correct for each client since they’re sharing the same progress file (status.json).

An idea I had would be to split this up into 2 client-side requests. The first request would return some kind of token to uniquely identify the client’s result file. Then the 2nd request can pass this token back to the server along with the “num” so that the server-side script knows which file to update for this client.

Is there a better way to do this?

Would you be able to make the jquery/jquery-ui.css available?

Many Thanks

Sounds like a cool bit of code, I do have a couple of questions though.

1.) Could the progress bar be updated using CSS? (i.e. changing the width of the “progress” from 0% to 100%) so it would start off 0% width, and increase to 100% (with a background color, say green)?

2.) What happens if the PHP ini time is very short (say 30 seconds) or the script that’s running is very long (say 1hr) – how can this be handled in the above?

Cheers

Mike

Yes sure you can use. Hope it helps to your project.

Also, I think you have a syntax issue in your php on line 8:

$arr = array(‘total’=–>’0′, ‘current’=>’0′);

Great tutorial here. May I use this in one of my open source projects?

Hi thanks for the reply. I tried your suggestion (moving the function to the bottom of the html page) but still the same thing. I checked the json file and it is updating and getting overridden every 3 secs with new value. Also I am setting the numbers to be 10000 or more. I tried it in IE9, Chrome and Firefox. Any more help will be very appreciated. Thank you.

@Leo try moving the $(document).ready(function(){…} script to the bottom of the html file just before tag rather than in the .

also you can check the json file and see if it is getting overridden every 3 sec with new value.

if you put far less number to count lets say 100, the process may complete before 3 sec and become 100% suddenly. change the 3000 ms to much less.
