PHP script sending duplicates of an email

[roldahayes]

Hi,

 

I have a section of code that sends an order confirmation to me when a customer places an order with us.

 

This all works fine but recently, I have started to get duplicate confirmations coming from the same customers, one in particular, many times a day...

 

Is there anything obvious about this code that could be causing it?

 

Thanks,

I don't see anything that empties the basket once an order was placed.
