Question

我想以荷兰语格式输入MySQL中的日期。现在他给了我标准格式。我是否需要在输出列表或插入文件中更改它？

这是我的插入代码：

<?php
session_start();


include '../dbh.php';

$costname = $_POST['costname'];
$category = $_POST['category'];
$subcategory = $_POST['subcategory'];
$price = $_POST['price'];
$info = $_POST['info'];
$costdate = $_POST['costdate']->format("d-m-Y H:i:s");
$iduser = $_SESSION['id'];

if(empty($costname)) {
  header("Location: ../dashboard.php?error=emptycostname");
  exit();
}

if(empty($category)) {
  header("Location: ../dashboard.php?error=emptycatergory");
  exit();
}

if(empty($subcategory)) {
  header("Location: ../dashboard.php?error=emptysubcatergory");
  exit();
}

if(empty($price)) {
  header("Location: ../dashboard.php?error=emptyprice");
  exit();
}

if(empty($info)) {
  header("Location: ../dashboard.php?error=emptyinfo");
  exit();
}

 else {
  $sql = "INSERT INTO costs (costname, category, subcategory, price, info, userid, costdate)
  VALUES ('$costname', '$category', '$subcategory', '$price', '$info', '$iduser', '$costdate')";

  $result = mysqli_query($conn, $sql);

  header("Location: ../dashboard.php");

}

现在我需要将它显示在列表中，我已经使用此代码从db：

获取它

<?php
include('includes/sessionstart.php');
include 'dbh.php';
if (isset($_SESSION['id'])) { ?>


    <?php include 'includes/header.php';




    // costslist define mysql
    $sql_costs = "SELECT * FROM costs WHERE userid='".$_SESSION['id']."'";
    $result_costs = mysqli_query($conn, $sql_costs);




    $costname = $row_costs['costname'];





    <div class="content">
        <div class="container-fluid">
            <div class="row">
                <div class="col-md-12">

您可以使用MySQL的DATE_FORMAT函数格式化它，无论您想要什么。以下是更新选择查询以对其进行格式化的方法：

$sql_costs = "SELECT *, DATE_FORMAT(costdate, '%d-%m-%Y %H:%i:%s') AS costdate FROM costs WHERE userid='".$_SESSION['id']."'";

在此处详细了解DATE_FORMAT功能：
