Re: Re: Problems w/ insert

Ethan,

I am curious why you are using mysqli_stmt_bind_result() on a statement 
that is an INSERT query? I don't use mysqli, but as I read the 
documentation it seems to me that this method is intended to bind 
results from a SELECT query into variables so that you can simply call 
mysqli_stmt_fetch() in a loop and have the variables magically contain 
the data from the next row.

Perhaps mysqli is confused because you are both mapping data to be bound 
(with mysqli_stmt_bind_param()) and to be returned (with 
mysqli_stmt_bind_result()) on the same INSERT query?

If you are just trying to insert, you should only need 
mysqli_stmt_bind_param() (which, by my count, has one parameter too many 
right now in your code) and mysqli_stmt_execute()   (and probably not 
mysql_stmt_bind_param() and mysql_stmt_fetch()). See "Example #2" here: 
http://us.php.net/manual/en/mysqli-stmt.execute.php
