Duplicate Orders/Order Confirmation

[Mr.Pibb]

Been getting the same problem intermittently. Is this a Paypal problem, a Zen Cart problem? Interesting that the Paypal transaction information is the same in both orders.
HELP!!!

We also have had an increase in duplicate orders and confirmation. Deleting and restocking used to resolve this but we discovered that sometimes stock is taken out, sometimes not and now it appears that sometimes it's taking some of the items and not other items in the same order. Now we have to check inventory in every duplicate order.

Just to clarify, it's only Paypal orders that this happens with.

Well now I just had a customer pay with Paypal and nothing showed up in ZenCart at all! I wouldn't have noticed if he hadn't sent me an e-mail because he couldn't check the status of the order...

Yes I had the same issue earlier this week. I had an order placed that the only reason I know it was placed was because I received the paypal notification of payment. I checked everywhere in zen cart and nothing. Only where the customer signed up for an account. I promptly sent the customer an email asking to verify the order and all was well.

The only thing I can figure that caused my issue was that paypal did not return to the cart the "all ok" sign to allow zencart to do it's thing.

[Mr.Pibb]

Did that happen to you on the 14th? Maybe PayPal was having problems?

[kameleon]

Yes happened on the 14th. I fully blame paypal. ;)

I had the double orders occur on October 30th and November 2nd - transaction IDs are identical, but order numbers are consecutive. Customers were only charged once, but recieved two order confirmations and so were concerned that their orders had processed twice. Transaction types show as "unique" for one order and "web_accept" for the second. I am running the very latest version of ZenCart.

Hi everybody, i too get a lot of duplicate orders even with the fix listed in the page three (www.acousticsamples.net). It seems that there are no solution to this but still i may try something in javascript.
In the fix, you try to disable an input type=image which works in firefox, but not in safari or IE... So there are other solutions even if i will try to find something better. It's simply to remove that button :)

so the script now looks like this:

PHP Code:

function submitonce()
{
  var button = document.getElementById("btn_submit").style.display = 'none';
  alert("");
  //button.style.color = "red";
  setTimeout('button_timeout()', 1000);  
  return false;
}
function button_timeout() {
  var button = document.getElementById("btn_submit").style.display = 'true';
  //button.style.color = "black";
} 


I will add a little ajax message as i use mootools on my website to make it look a little better, but at least i'm sure that this prevents the double clicking in the major web rowsers.
By the way if you use the css butons, i just checked the code and there is no more id to the button so the fix just can't work...

Don't forget to remove the alert(""); line that was just here for testing.
Oh and by the way i'm not sure that this will work just like people want it to, but it does for me at least, i will test a little more on my local test site and the put it online to see if it truly fixes it.
