如何在mysql中将日期格式从ddmmyy更改为yymmdd以插入数据库中

Question

你好，朋友，我想将HTML表单中的数据插入MySQL数据库，但在日期格式方面遇到一些错误

       <?php

include_once 'Configuration.php';

$Dateee = $_POST['form_fields[date]'];
$am113d = $_POST['form_fields[am113d]'];
$am112d = $_POST['form_fields[am112d]'];
$am111d = $_POST['form_fields[am111d]'];
$pm13d = $_POST['form_fields[pm13d]'];
$pm12d = $_POST['form_fields[pm12d]'];
$pm11d = $_POST['form_fields[pm11d]'];
$pm53d = $_POST['form_fields[pm53d]'];
$pm52d = $_POST['form_fields[pm52d]'];
$pm51d = $_POST['form_fields[pm51d]'];
$pm63d = $_POST['form_fields[pm63d]'];
$pm62d = $_POST['form_fields[pm62d]'];
$pm61d = $_POST['form_fields[pm61d]'];
$pm73d = $_POST['form_fields[pm73d]'];
$pm72d = $_POST['form_fields[pm72d]'];
$pm71d = $_POST['form_fields[pm71d]'];



$sql = "INSERT INTO `Draw_tabel` (`Date`, `A113d`, `A112d`, `A111d`, `A133d`, `A132d`, `A131d`, `A173d`, `A172d`, `A171d`, `A183d`, `A182d`, `A181d`, `A193d`, `A192d`, `A191d`) VALUES ('STR_TO_DATE(`date`, '%d-%m-%Y')', 'am113d', 'am112d', 'am111d', 'pm13d', 'pm12d', 'pm11d', 'pm53d', 'pm52d', 'pm51d', 'pm63d', 'pm62d', 'pm61d', 'pm73d', 'pm72d', 'pm71d');" ;


if (mysqli_query($conn, $sql)) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "<br>" . mysqli_error($conn);
}

mysqli_close($conn);
?>

使用PDO https://www.w3schools.com/php/php_mysql_prepared_statements.asp

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDBPDO";

try {
    $conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
    // set the PDO error mode to exception
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    // prepare sql and bind parameters
    $stmt = $conn->prepare("INSERT INTO MyGuests (firstname, lastname, email)
    VALUES (:firstname, :lastname, :email)");
    $stmt->bindParam(':firstname', $firstname);
    $stmt->bindParam(':lastname', $lastname);
    $stmt->bindParam(':email', $email);

    // insert a row
    $firstname = "John";
    $lastname = "Doe";
    $email = "[email protected]";
    $stmt->execute();

    // insert another row
    $firstname = "Mary";
    $lastname = "Moe";
    $email = "[email protected]";
    $stmt->execute();

    // insert another row
    $firstname = "Julie";
    $lastname = "Dooley";
    $email = "[email protected]";
    $stmt->execute();

    echo "New records created successfully";
    }
catch(PDOException $e)
    {
    echo "Error: " . $e->getMessage();
    }
$conn = null;
?>
