php - 从输入 [] 获取数据时从 PDO 中的数组重复插入时循环困惑

Question

• 有一个特殊的出勤和缺勤项目作为大学的职责
• 我创建了一个表单，通过使用 [] 到 git 数组来 git 他的输入表单数据库
• 一切正常但是:
• ** 当我从我的表单中插入数据时，我找不到正确的方法让它正常工作 **
• 我曾经循环 ** for ** 以转到下一个索引和 ** foreach ** 以获取单选按钮的索引

这是我的表格，我从数据库中获取了它:

显然您使用的 bindParam 不是最正确的方式。

根据这个:https://www.w3schools.com/php/php_mysql_prepared_statements.asp ，您应该在循环之前绑定(bind)它们，并使用循环仅适配您绑定(bind)的变量。

我将使用您的代码作为示例，好吗？

if (!empty($_POST)) {
    $insert_stu_Attend = $db->prepare("insert into test  values (?,?,?,?,?,?,?,?)");
    $insert_stu_Attend->bindParam(1, $first);
    $insert_stu_Attend->bindParam(2, $second);
    $insert_stu_Attend->bindParam(3, $third);
    $insert_stu_Attend->bindParam(4, $forth);
    $insert_stu_Attend->bindParam(5, $fifth);
    $insert_stu_Attend->bindParam(6, $sixth);
    $insert_stu_Attend->bindParam(7, $seventh);
    $insert_stu_Attend->bindParam(8, $eighth);

    foreach ($IdStu as $key => $s) {
        $dd = 1;
        $first = $IdStu[$key];
        $second = $monthe;
        $third = $item;
        $forth = $classe;
        $fifth = $thisDay;
        $sixth = $attends[$s];
        $seventh = $excusables[$s];
        $eighth = $attendNote[$key];
        $insert_stu_Attend->execute();
    }
}

根据文档，它应该可以工作。让我知道进展如何。

编辑我删除了 for 并仅保留了 foreach，因为考虑到为此结果发送的用户数量，我假设您正在使用 FOR 循环遍历来自不同数组的结果。
