Duplicate entry '29' for key 'PRIMARY'

Hi Jason,

I thought I would put this under a new thread although I still have a few other questions.

Now if I go through the checkout process if I have one item in the cart the only issue is the email not getting through. However if I have more than one item in the cart I get an error "Duplicate entry '29' for key 'PRIMARY'"

Now I have look through several threads I have confirmed that the ID columns are "int" and set to auto increment. I think I just about exhausted all teh other suggestions. Do you have any ideas as to why this is now happened?

I should mention that this wasn't happening before we did our session. However another issue popped up that wasn't happening before probably because I chose a different product for the test. This one had a SKU which is not just numbers as many of my clients products have. I went into eStore Details Database and changed "DetailProdID" to text. This fixed the issue of accepting the "mixed" product code or SKU.

But then I tried a test with multiple items and the Duplicate entry '29' for key 'PRIMARY' started showing up. Any ideas on this one?

I added some clips from the database. please let me know if you need anything else.

in the store order summary behavior, you are saving the Item ID value to the OrderID Column of the orders table.

the orderID column of the orders table is the primary key column. You should not assign a value to the primary key column, you should let the database populate that column automatically. let the database create a unique ID for each record rather than trying to force a value. the error is happening because you are forcing a value to the orderID column which is set to not allow duplicate values.

Hi Jason,

The only place I can see the cart trying to write anything to the OrderID column is in the store Cart Summary in Database screen. Are you saying that I should remove that line ... <?php echo $dtelecart->DisplayInfo("ID"); ?>

The only other place I can see it when it looks to be pulling that info from the Orders table and copying it to the orderdetails table ... <?php echo ((isset($_SESSION["dtelecart_OrderID"]))?$_SESSION["dtelecart_OrderID"]:""); ?>

Could I have added it someplace else as well?

Yes, exactly.

In the store order summary behavior you should not be saving any value to the OrderID column which is the primary key column for that table. leave that column unbound.

Hi Jason,

So I believe I have cleared anything writing to the OrderID column. There should be nothing writing to it but i still get a - Duplicate entry '29' for key 'PRIMARY' when I try to add more than one product to the cart. It should be working now shouldn't it?

Are you sure it's the "Orders" table that is causing the error? Not the Order Details? That is where it seems to be trying to write the individual detail lines of an order and crashing.

Thanks for helping on this one. Just need to get this one last part working.Cheers!

In the store order details behavior, you have the DetailID column bound to the Order ID Session, again, this column is the Primary key column for that table and should not have a binding.

Yes, I had removed that before and it didn't make a difference. I have it working now but it was not just the session in the OrderDetials.

What was throwing everything off was the for some reason the DetailOrderID column was set as auto increment and the primary key. I changed DetailID to be auto increment and the primary. Somehow when creating the cart I must have chosen this column as the key column when ecart created the table.

Looks to be working, hope everything goes smoothly now. Thanks for you help!

Glad to hear it is working.
