Problem in highlighting display data using SELECT Statement with css class

[newphpbees]

Hi...

I have query in highlighting null data using this code:



<?php

include 'config.php';

$currentEmpID = $_SESSION['empID'];

if(!isset($_POST['Regsubmit_'])){

$DATE1 = $_GET['Regfirstinput'];
$DATE2 = $_GET['Regsecondinput'];

$sql = "SELECT DISTINCT IF(ISNULL(a.LOG_IN), 'rdc', '') AS LOGIN_CLASS, IF(ISNULL(a.LOG_OUT), 'rdc', '') AS LOGOUT_CLASS, a.EMP_ID, CONCAT(LASTNAME, ', ' , FIRSTNAME) AS FULLNAME, a.LOG_IN, a.LOG_OUT
FROM $ATTENDANCE.attendance_build AS a JOIN $ADODB_DB.employment em ON (a.EMP_ID = em.EMP_NO AND em.STATUS IN ('Reg Operatives', 'Reg Staff'))
WHERE LOG_IN BETWEEN '$DATE1' AND '$DATE2'
OR ISNULL(LOG_IN) OR ISNULL(LOG_OUT)";

$DTR = $conn3->GetAll($sql);
$smarty->assign('attendance', $DTR);
}
$smarty->display('header_att.tpl');
$smarty->display('RegAttendance.tpl');
$smarty->display('footer.tpl');
?>


and here is the tpl code:



{section name=att loop=$attendance}
<tr>
<td colspan="2">{$attendance[att].EMP_ID}</td>
<td colspan="2">{$attendance[att].FULLNAME}</td>
<td colspan="2" class="{$attendance[att].LOGIN_CLASS}">{$attendance[att].LOG_IN|date_format:"%d-%m-%Y %I:%M %p"}</td>
<td colspan="2" class="{$attendance[att].LOGOUT_CLASS}">{$attendance[att].LOG_OUT|date_format:"%d-%m-%Y %I:%M %p"}</td>
</tr>
{sectionelse}
<tr><td colspan="1">No DATA</td></tr>
{/section}


this code highlight the null value of login or logout or both.

this is the css:


.rdc {background-color:#ff0000;}


Now, I need to revised my query statement, because i have separate code for adding attendance if the employee has no attendance or no login or no logout.

I just want to happen is if the employee is already add his attendance in NRS table or should I said if the LOG_IN in attendance table is equal to TIME_IN in NRS table the data will have a color yellow.

For Example:

I have this data in attendance table:

EMP_ID = 012012
LOG_IN = NULL
LOG_OUT = 2011-12-12 13:35:00

I will his attendance in NRS table to have his attendance:

EMP_NO = 012012
TIME_IN = 2011-12-12 05:35:00
TIME_OUT = 2011-12-12 13:35:00



In my above query the LOG_IN has a background color of RED.

I want to happen is if I add his attendance in NRS the EMP_NO, LOG_IN, LOGOUT will have a color to notice that it is already have in NRS.

Because theirs a scenario that the employee has no login or no logout or both.


Feel free to ask me if my explanation is not clear to you.

Thank you in advance
