I have this php file for store the logout time. Using insert query I store the login time first. Then I store the logout time using this logout script. The error I'm getting is the one I mentioned in my code which is failed to insert logout time
. the $lgotime
and $lrec
are echoing correctly. Below is my code:
<?php
session_start();
$lgotime = date("Y-m-d H:i:s");
$lrec = $_SESSION['lreclast'];
echo $lgotime;
echo "</br>";
echo $lrec;
mysql_query("UPDATE tbl_login_record SET logoff_time='$lgotime' WHERE id = '$lrec'") or die("failed to insert logout time");
session_destroy();
header("Location:../login.php");
?>
the $lrec
variable is coming from mysql_insert_id()
from the script that has the insert query. Help will be really appreciated.
if your mysql query dosent work you can change your code like this:
mysql_query("UPDATE tbl_login_record SET logoff_time='".$lgotime."' WHERE id = '".$lrec."'") or die("failed to insert logout time");
it always works for me!
The problem is that your query is not sending the data, its sending strings
mysql_query("UPDATE tbl_login_record SET logoff_time='$lgotime' WHERE id = '$lrec'") or die("failed to insert logout time");
Should be,
mysql_query("UPDATE tbl_login_record SET logoff_time='{$lgotime}' WHERE id = {$lrec}") or die("failed to insert logout time");
To be honest I would not suggest this either and would use parametrized queries instead.
Please give it a try. You are not using session_start()
on top of this page and change query as
<?php
session_start();
$lgotime = date("Y-m-d H:i:s");
$lrec = $_SESSION['lreclast'];
echo $lgotime;
echo "</br>";
echo $lrec;
mysql_query("UPDATE tbl_login_record SET logoff_time='".$lgotime."' WHERE id = '".$lrec."'") or die("failed to insert logout time");
session_destroy();
header("Location:../login.php");
将查询更改为以下格式,然后尝试,
mysql_query("UPDATE tbl_login_record SET logoff_time='".$lgotime."' WHERE id = '".$lrec."'") or die("failed to insert logout time");
只需从查询中的ID中删除单引号 ,因为它是整数而不是String
mysql_query("UPDATE tbl_login_record SET logoff_time='$lgotime' WHERE id = $lrec") or die("failed to insert logout time");
