Duplicate Orders/Order Confirmation

[stardotstar]

Following this with interest. I have latest versions and getting intermittant duplicate orders following the common pattern:

web_submit and unique only difference being the order id #

I also note that turning off the PDT as recommended elsewhere removed the duplicate notice in the IPN listings in ZC but not the duplicate orders themselves - ie still coming through in email. Seems that only the second one actually "Takes" for me.

I have just made the changes suggested in page 3.

I also have duplicate orders on my shop, happens randomly with either PayPal or iDeal (Dutch system).
I wonder if it has anything to do with the version of PHP on the hosting server. Mine has php 5.2 and maybe soon One.com will upgrade to PHP 5.3 will that be of any help?
If you also have these double orders, please let's find out if the version of PHP could be causing this issue. Since nobody has a really good working solution? Let's try to fix this one way or another.
In Admin you can click on Version and on the left side it shows PHP 5.2 What's your version?

Mine shows :
PHP Version: 5.2.5
But i really don't think that's the problem...

I'm still having the double orders once in a while. I did every suggestion from this forum, but still no solution. I really hope someone comes up with a fix as I think that this is one of the basic functions of a webshop. Is everyone having this issue? This issue has been on my mind and still is for the last 2 months. Each time I receive an order, I cross my fingers it's not doubled.

Please people, how can we fix this??

Interesting. Today I got a duplicate order that was actually a FREE file. I run a digital download store and I have one product that is free. Someone "purchased" it and I got two order numbers for it, a few seconds apart. I think this might be a case of the user clicking more then once, but I'm not sure.

PHP Version: 5.2.8
Zen Cart 1.3.8a
Patch: 1::
Database Patch Level: 1.3.8

Interesting, I saw this post and was getting ready to say that I haven't had a duplicate order in quite a while. Then I got a duplicate order a few minutes ago....sigh...

So if sykadelx had the duplicate order issue and the customer didn't check out through PayPal, then this is probably a Zen Cart issue?

I am convinced that this is a Zen-Cart issue, not a Paypal issue as I've had this with both my paying methods.
How about we add a script to the order.php that will check if there has already been an order for this customer in the last minute? How hard would it be to add this?

So if it's not the php version, maybe we can compare the session settings we're using. In Configuration - Sessions, these are my settings:

Session Directory /<customerfolder>/httpd.www/cache
Cookie Domain True
Force Cookie Use False
Check SSL Session ID False
Check User Agent False
Check IP Address False
Prevent Spider Sessions True
Recreate Session True
IP to Host Conversion Status true

If you have the same issues as I do, please let me know if you're using the same settings?

Did you follow the fix over in http://www.zen-cart.com/forum/showthread.php?p=544255 ?

I am using an upgraded 1.3.9h from 1.3.8.
I have installed the Ultimate SEO URLS plugin and a facebook "like" button.
HTTP Server: Apache/2.0.54
PHP Version: 5.2.14

I am also getting occasional double orders, where both myself and the customer recieve double order confirmations with different confimation #s however the customer will only be charged once. Customers email with concern that they may have been doubly charged. This happened occasionally prior to upgrading, and I thought it was fixed in the new version (I've seen the code change in jscript_main.php, but it didn't fix the problem). I have gone through this entire post for fixes, and have found no working answers.

I appreciate any help, Thanks!
