我有一个php，mysql数据库名称daily_data2我可以使用日期timepicker（第一个查询）过滤日期范围中的表，我也可以按照每个dept（第二个查询）进行过滤，这两个过滤选项在不同的按钮中工作，但我的问题是如何使用第一个查询中的结果来过滤每个部门（第二个查询）？或者我应该只在1个条件下合并我的2个查询？有人能帮我吗。以下是我的代码。
<?php
$post_at = "";
$post_at_to_date = "";
if(isset($_POST['post_at']) && isset($_POST['post_at_to_date']))
{
$post_at = $_POST['post_at'];
$post_at_to_date = $_POST['post_at_to_date'];
$query = "SELECT * FROM daily_data2 WHERE Checkdate between '" . $post_at . "' and '" . $post_at_to_date . "'";
$search_result = filter($query);
}
else {
$sql = "SELECT * FROM daily_data2";
$search_result = filter($sql);
}
function filter($query)
{
$connect = mysqli_connect("localhost", "root", "","bio_db");
$filter_Result = mysqli_query($connect, $query);
return $filter_Result;
}
?>
<?php
if(isset($_POST['go']))
{
$cmbDept = $_POST['cmbDept'];
$query ="SELECT * FROM $row array WHERE Campaign LIKE '".$cmbDept."' ";
$search_result = filterTable($query);
}
function filterTable($query)
{
$connect = mysqli_connect("localhost", "root", "","bio_db");
$filter_Result = mysqli_query($connect, $query);
return $filter_Result;
}
?>

加入查询并保留一个，例如：
if(isset($_POST['post_at']) && isset($_POST['post_at_to_date']))
{
if(isset($_POST['go'])) {
$cmbDept = $_POST['cmbDept'];
$post_at = $_POST['post_at'];
$post_at_to_date = $_POST['post_at_to_date'];
$query = "SELECT * FROM daily_data2 WHERE Campaign LIKE '".$cmbDept."' " AND Checkdate between '" . $post_at . "' and '" . $post_at_to_date . "'";
} else {
$query = "SELECT * FROM daily_data2 WHERE Checkdate between '" . $post_at . "' and '" . $post_at_to_date . "'";
}
} else {
if(isset($_POST['go'])) {
$cmbDept = $_POST['cmbDept'];
$query = "SELECT * FROM daily_data2 WHERE Campaign LIKE '".$cmbDept."'";
} else {
$query = "SELECT * FROM daily_data2";
}
}
$search_result = filter($query);
function filter($query)
{
$connect = mysqli_connect("localhost", "root", "","bio_db");
$filter_Result = mysqli_query($connect, $query);
return $filter_Result;
}

感谢你们，我终于明白了，我只是将我的2个查询合并为一个，这里是我想出了我的查询。希望它有所帮助
if(isset($_POST['post_at']) && isset($_POST['post_at_to_date']) && isset($_POST['cmbDept']))
{
$query ="SELECT * FROM daily_data2 WHERE Campaign = '".$cmbDept."' and Checkdate between '{'" . $post_at . "'}' and '{'" . $post_at_to_date . "'}'";
}
