Yes, thats it.
My first guess would be, if not aleady done, initialize
$auction_parts before you do your bind_param() with something like:
$auction_parts = array('id' = null, 'name' = null, ...);
$insert-bind_param(issdsis, $auction_house[id], ...);
Unfortunately it helps nothing :-(
Ok, i didn't really think it would but might have shown a obvious
bug with mysqli.
According to your original post it was odd that the update prepared
statment didn't complain about a NULL value, but the insert did,
and it does seem to be related to bind_param and prepare.
What are your versions of:
php?
mysql_client php is built with?
mysql server you are connecting to?
I've alread a solution, just forgot to post here :)
Anthony gave me the hint as he sent me a list of the datatypes accepted
by bind_param and so I checked the datatypes of the variables and have
seen that $auction_house[id] was a string and not an integer.
After I converted it to an integer, it works properly.
I don't know exactly why it worked if I did bind_param in the loop but I
think it's because it saw there that I gave him a string and converted
it automatically to integer.

initalization of the variables because it works if I have the bind_param

But to have the bind_param in the loop isn't the best solution I think.

'sssd' defines the datatypes of the 4 arguments you're passing in.
I know the example ;-)
I checked the statement now without the loop, but defined the variables
also after the bind_param.
Very interesting is that it works if I write $auction_parts[...] =
...; but that it doesn't if I write $auction_parts = array(... =

I output already some variables in the loop and all are set with correct values. As I said, if I do the bind_param inside the loop it works without problems.

Re: [PHP] Prepared statements
One other thing: If I do the bind_param within the loop, it just works. The curious is that I have to prepared statements for this loop (one for inserting data and one for updating data) and the one for updating data works and that for inserting don't.
