mysqli错误-bind_param:变量数不匹配 [英] mysqli error - bind_param: number of variables doesn't match
问题描述
我遇到以下错误,但是我一遍又一遍地数了数,一切似乎都很好.有人有任何想法吗?
I am getting the following error but I have counted things over and over again and everything appears to be fine. Anyone have any ideas on it ?
错误:
警告:mysqli_stmt :: bind_param()[mysqli-stmt.bind-param]: 变量与准备好的语句中的参数数量不匹配 /home/ambnews/public_html/invoice/response.php 在线 204
Warning: mysqli_stmt::bind_param() [mysqli-stmt.bind-param]: Number of variables doesn't match number of parameters in prepared statement in /home/ambnews/public_html/invoice/response.php on line 204

推荐答案
您需要查看手册:
- 使用准备好的语句时,您不应转义您的值,因为您将在数据中添加文字反斜杠.
- 您不应在查询中插入变量,而应使用占位符(mysqli中的问号).这些都与您的价值观息息相关.
因此您的查询将是:
$query = "INSERT INTO store_customers (
name,
email,
// etc.
) VALUES (
?,
?,
// etc.
);
";
然后绑定值:
$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()
,因为这似乎只使用一次,所以不需要绑定参数,您可以直接绑定值.但这并没有什么不同.
Note that I am using bind_value()
instead of bind_param()
as this seems to be used once only so there is no need to bind parameters, you can bind the values directly. It should not make a difference though.
