Question

似乎无法弄清楚这个问题是什么。我之前使用过相同的方法，但每个用户都没有使用内部方法。我得到一个Uncaught exception 'PDOException' with message 'SQLSTATE[HY093]: Invalid parameter number: parameter was not defined'，但从我看到的一切都正确匹配。

我将user_id和day设置为数据库中的唯一键组。 $ output为一周中的每一天的每个小时存储值（1或0）。每天为每个用户插入每个小时的整周值（仅插入的user_id和day值发生变化）。

$user_set = array(1, 5, 8, 24) //user ids to insert for

$weekdays = array(1 => 'mon', 2 => 'tue', 3 => 'wed', 4 => 'thu', 5 => 'fri', 6 => 'sat', 7 => 'sun');

$hourDefs = array('12am', '1am', '2am', '3am', '4am', '5am', '6am', '7am', '8am', '9am', '10am', '11am', '12pm', '1pm', '2pm', '3pm', '4pm', '5pm', '6pm', '7pm', '8pm', '9pm', '10pm', '11pm');


//build query for multi insert
$sql = 'INSERT INTO weekly_sched (

Answer 1

将参数名称中的所有连字符更改为下划线。例如，

        :user_id'.$n.'-'.$n2.',

应该是：

        :user_id'.$n.'_'.$n2.',

它将此解释为:user_id$n minus $n2。

sql多插入函数的参数错误无效
