我的数据库中的日期字段正在填充0000-00-00。我需要在用户点击登录按钮时插入该字段与系统日期。我无法检测到问题。我有一个变量$ date指定功能日期（＆＃39; Ym-d＆＃39;）。

Answer 1

替换

 function updateOrDeleteEntitlements(context) {
    var role = $('#selectedRole').val();
    var ent = $(context).data('entid');
    var binMe = '';

     $.ajax({
      url: 'ajax/update_delete_entitlements.php',
      type: 'post',
      data: {'role': $role, 'ent': ent, 'delete': $binMe},
      success: function(data) {
        console.log(data);
      }
    }); 
 }

与

@$date=$_POST[date('Y-m-d')];

Answer 2

取代@$date=$_POST[date('Y-m-d')]使用@$date = date('Y-m-d H:i:s'); 在Mysql数据库字段中选择数据类型DATETIME。

<?php
    if(isset($_POST['login']))
    {
      @$username=$_POST['username'];
      @$password=$_POST['password'];

      //@$date=$_POST[date('Y-m-d')];
      @$date = date('Y-m-d H:i:s');


    $query = "select * from userinfotbl where username='$username' and password='$password' ";
                    $query1="insert into userinfotbl values('$date')";
    //echo $query;
    $query_run = mysqli_query($con,$query);
                    $query_run1 = mysqli_query($con,query1);
    //echo mysql_num_rows($query_run);
    if($query_run)
    {
        if(mysqli_num_rows($query_run)>0)
        {
        $row = mysqli_fetch_array($query_run,MYSQLI_ASSOC);

        $_SESSION['username'] = $username;
        $_SESSION['password'] = $password;

        header( "Location: homepage1.php");
        }
        else
        {
            echo '<script type="text/javascript">alert("No such User exists. Invalid Credentials")</script>';
        }
    }
    else
    {
        echo '<script type="text/javascript">alert("Database Error")</script>';
    }
}

?>

您好，您只需要将date数据类型更改为timestamp并设置默认CURRENT_TIMESTAMP。这将自动添加日期值列，您无需在查询中提供日期。
