Question

当我通过表单插入值时，我希望日期保存在MySQL数据库中。我不希望用户查看它，但我需要未来函数的日期，所以我可以遍历db中注册的日期。

我是否需要在表单中创建一个隐藏的输入字段，并将其与我的select.php对齐，还是有一种聪明的方法可以做到这一点？

<?php
include('session.php');
include 'dbconfic.inc.php';

    $stmt = $mysqli->prepare("INSERT INTO numbertable(numbers) VALUES(?)");
                    // bind variable: 'd' for digit/tal, 's' for string
                    $stmt->bind_param('d',intval($_POST["numbervalue"]));   // bind

                    // execute prepared statement 
                if ($stmt->execute()) { // tjek om udført:
                    $success = true;
                }

                // luk statement
                $stmt->close();

                // luk connection
                $mysqli->close();   

if($success) {
    echo "Insert Succesfull";
} else {
    echo "Failed: " .  $stmt->error;
}

?>

Answer 1

您必须创建像numdate这样的列作为DATETIME

试试这个：

<?php
include('session.php');
include 'dbconfic.inc.php';

    $stmt = $mysqli->prepare("INSERT INTO numbertable(numbers, numdate) VALUES(?, NOW())");
                    // bind variable: 'd' for digit/tal, 's' for string
                    $stmt->bind_param('d',intval($_POST["numbervalue"]));   // bind

                    // execute prepared statement 
                if ($stmt->execute()) { // tjek om udført:
                    $success = true;
                }

                // luk statement
                $stmt->close();

                // luk connection
                $mysqli->close();   

if($success) {
    echo "Insert Succesfull";
} else {
    echo "Failed: " .  $stmt->error;
}

?>
