我收到以下错误,但我一遍又一遍地计算了一切,一切似乎都没问题。有没有人有任何想法?
错误:

答案 0 :(得分:0)
您需要查看manual:
所以你的查询是:
$query = "INSERT INTO store_customers (
name,
email,
// etc.
) VALUES (
?,
?,
// etc.
);
";
你绑定你的价值观:
$stmt->bind_value(
'sssssssissssss',
$_POST['customer_name'],
$_POST['customer_email'],
// etc.
);
请注意,我使用的是bind_value()
而不是bind_param()
,因为它似乎仅使用一次,因此无需绑定参数,您可以直接绑定值。但它应该没有什么区别。
