Phil, you don't want to use an INSERT if you're just updating an
existing row. You can't do an INSERT and use the current row's values
(book.id/book_id/whatever) in your insert, since there IS no current
row. I'm assuming what you're trying to do is add a record to an
associative table that links Categories to Books, but only if that
Book title matches your $title string.
Try this:
foreach($categoriesIN as $category)
$sql = "update book_categories set category = '$category' where
book_id in (select id from book where title = '$titleIN')";
If that's not what you're going for, and you just wanted to update
something's category, try this:
foreach($categoriesIN as $category)
$sql = "update book_categories set category = '$category' where
book_id = '$somevalue'";
Perhaps it would help us help you if you would explain what it is
you're trying to accomplish with this query?
