Double Orders

[tfittsy]

I've got a few oscommerce stores. Some of them occasionally double charge the customer and put two orders in the admin. I'm just working on another one (I did modify the checkout pages fairly heavily) and now it does double inserts on every single purchase. I would imagine if I was testing with credit card numbers it would double charge them. The checkout_process is only being called once. What could cause double orders every single time? And on the other sites what could cause it occasionally?

 

I tried installing a javascript contribution to disable the submit button after it was clicked but we still got double orders. I also tried writing something in the checkout_process code that would check the last order that a customer made and made sure it was at least 120 seconds earlier. When I did that it wouldn't let me check out two times in less than two minuts, but when it did let me check out it ran it twice again. It makes me think the code is being run twice at the same time. Any help would be greatly appreciated.

my problem is similar...

 

the shop processes two orders (with counted up order numbers + two confirmation mails) when internet explorer is used!

 

@tfittsy: did you tried firefox or opera?

 

... everything works allright with firefox or opera in my shop.

 

 

Anybody an idea what the problem of the two orders can be? or where the problem must be located?

I've tried it with firefox and I can confirm that it works properly. I don't know what IE would have to do with processing the order twice though. I am using IE7. Which version of internet explorer are you using?

[FridayNight]

... the same

 

 

is it maybe a session problem?

[FridayNight]

... would be great if a oscommerce pro can give us some support :-"

[tfittsy]

I have tried it in IE 6 and it also does double orders in that version. Have any others experienced this? I don't have any idea where to start.

[FridayNight]

... it really smells like a BUG !

[tfittsy]

Did you edit your checkout pages at all? On my site that is doing the double orders I have added another box that is similar to the comments box and also on the shipping option page I added a delivery date and delivery time.

 

I have plenty of other osC sites that don't have this problem (at least not with every purchase.) and I think it could have been one of the changes I made, except for the fact that it works fine in FF and not at all in IE.

pretty sure that i installed at least one contribution affecting the checkout

 

would it help if we compare some files?

I suppose it could, but I don't even know which files it could be. it could be anything from the orders.php class file to the checkout_shipping, payment, confirmation, or process files.

[FridayNight]

you're right, no idea where to start debugging ... and after all i am just an average php coder ...

 

so, if somebody want's to have a look at some of my files please, your're very welcome!

[FridayNight]

i try to find a working backup from my shop and compare it with my latest one... this will take some time ...

[FridayNight]

... the first three backups didn't work, seems like the problem is older than I expected ...

 

@tfittsy: maybe you try the same?

[northerndreamer]

My store had it's first double order on 1/28/07. The customer was charged twice on their CC. I'm see 3 instances of checkout_success about 1 or two minutes apart, looking at my visitors report. This is weird.

[FridayNight]

@northerndreamer: did you also tested firefox/opera against internet explorer?

[FridayNight]

Finally I found a working backup ... so which file compare first?

 

(actually I continue working on this problem ... after a couple hours sleep)

[northerndreamer]

@northerndreamer: did you also tested firefox/opera against internet explorer?

I don't have either installed, so no I haven't tried it.

@tfittsy: maybe you try the same?

 

My backups all seem to show the same problem. I'll try to find something a little further back.

Which file shall I examine next?

[FridayNight]

... just to many files ... I try to find the two backups which follow each other and compare them ...

[FridayNight]

... there is no other way ... I have to find and solve this double order ie problem ...

 

@tfittsy: is your checkout ssl secured?

[FridayNight]

This is really a hard one! I tried a lot things in the configure.php but unfortunately without success...

 

HELP! :'(

[FridayNight]

... switched off ssl ... with no effect ... still two orders with IE ...

 

 

8 backups and still no progress ... :'(

my checkout page does have ssl. It does the same thing whether it's on or off.
