如何过滤日期是否包含时间

Question

我只想按选择日期在日期之间进行过滤。我的数据库已输入具有不同时间值的日期记录。但我只想过滤日期。

这是我的代码

<?php  
 //filter.php  
 if(isset($_POST["from_date"], $_POST["to_date"]))  
 {  
      $connect = mysqli_connect("localhost", "", "", "");  
      $output = '';  
      $query = "  

      SELECT 
      CreatedDate,
      COUNT(`Ticket`) AS Tickets,
       SUM(CASE WHEN status = 'Closed'  THEN 1 ELSE 0 END) as Closed 
      
      FROM Dashboarddetails

 
      WHERE CreatedDate BETWEEN '".$_POST["from_date"]."' AND '".$_POST["to_date"]."'
      GROUP BY CreatedDate
ORDER BY CreatedDate
";  

请找到图片，这是获取当前代码的结果。

您可以使用DATE（）函数
并且您应该避免在sql代码中使用php var来防止sqlinjection，为此，请为您的db driver看一下预先准备好的statemente和binding param

基于事实，您正在使用msqli而不是可以使用的PDO

if(isset($_POST["from_date"], $_POST["to_date"]))  
 {  

    $connect = mysqli_connect("localhost", "", "", "");  
    $output = '';  
    $stmt = $connect->prepare("CreatedDate,
        COUNT(`Ticket`) AS Tickets,
        SUM(CASE WHEN status = 'Closed'  THEN 1 ELSE 0 END) as Closed 
        FROM Dashboarddetails"; 
        WHERE CreatedDate BETWEEN DATE(?) AND DATE(?)
        GROUP BY CreatedDate
        ORDER BY CreatedDate");
    $stmt->bind_param('ss',$_POST["from_date"], $_POST["to_date"]);
    $stmt->execute();

    $result = $stmt->get_result();
     while ($myrow = $result->fetch_assoc()) {
     ....
    }

   ..... 

无论如何，请确保您在POST中的日期是规范格式的日期字符串，并且两个日期的date（）部分是有效的日期范围（如果您传递的两个日期在同一天之间，则子句之间不起作用）
