我正在尝试从 MySQLi 准备好的语句中获取数据，但希望获取使用表单顶部的日期选择器选择的日期范围的数据。在我尝试向其中添加日期范围部分之前，这一切都很完美。这是我的表单页面的代码:
<?php
include_once 'includes/db_connect.php';
include_once 'includes/functions.php';
sec_session_start();
?>

最佳答案
您的表单使用 method="get"，但您从 POST 数据中检索日期值，但该数据不可用:
if (isset($_POST['t1']))
$from = $_POST['t1'];
if (isset($_POST['t2']))
$to = $_POST['t2'];
因此，查询的日期条件有空值并且失败:
AND set_date BETWEEN '' AND ''
您应该使用:
if (isset($_GET['t1']))
$from = $_GET['t1'];
if (isset($_GET['t2']))
$to = $_GET['t2'];
返回结果:
AND set_date BETWEEN '2015-7-2' AND '2015-7-15'
太明显了，我完全错过了。并且不要忘记绑定(bind)准备好的语句中的值以避免 SQL 注入(inject)。
