Question

您好我是php的初学者，我尝试使用日期列从表（billing_details）中检索数据（在单个列的两个日期之间即预订）

下面是源代码

$from = mysql_real_escape_string($_POST['from']);
$to = mysql_real_escape_string($_POST['to']);
$from = date("d-m-Y", strtotime($from));
$to = date("d-m-Y", strtotime($to));

echo $from; 

$sql = mysql_query("select * from billing_details where SRF ='$_POST[srf]' or Service_Type ='$_POST[service]' or Status ='$_POST[status]' or Branch ='$_POST[branch]' or DATE(`Booking`) between '".$from."' and '".$to."'");

 ![I have select two different dates to get datas between the selected dates , but nothing is retrieved, only the echo $from is retrieved the the selected date][1]


Kindly help me to solve this issue, Thanks in advance

Answer 1

我相信你必须将一个变量分配给$ _POST，而不是像那样输入。

修改

$sql = mysql_query("select * from billing_details where SRF ='$_POST[srf]' or Service_Type ='$_POST[service]' or Status ='$_POST[status]' or Branch ='$_POST[branch]' or DATE(`Booking`) between '".$from."' and '".$to."'");

对于你的$ _POST [srf]和$ _POST [service]，请这样说：

$srf = $_POST['srf']; $service = $_POST['service']; $sql = mysql_query("SELECT * FROM billing_details WHERE SRF = '$srf' or Service_Type = '$service'.... etc etc")

Answer 2

您的索引缺少单引号会更改您的查询

$sql = mysql_query("select * from billing_details where SRF ='".$_POST['srf']."' or Service_Type ='".$_POST['service']."' or Status ='".$_POST['status']."' or Branch ='".$_POST['branch']."' or DATE(`Booking`) between '".$from."' and '".$to."'") or die(mysql_error());

不要将Global直接用于您的查询。

了解mysqli或PDO，因为mysql已被弃用。

Answer 3

您的日期格式不正确，应该是＆＃39; Y-m-d＆＃39;否则mysql将无法识别它。学习习惯这种格式：）

此外，由于您是初学者，请注意您应该检查strtotime返回。它的计算结果为false然后输入无效并将其传递给date（）函数将导致1969-12-31我相信
