CakePHP: Cannot determine the total working hours of employees - php

Question

What I want:- I want to calculate the total working hours of my employees based on the working hours of multiple days.
My problem the total working hours ($total_hours) is not working.
My Model
class Attendence extends AppModel {
function add($data){
if (!empty($data)) {
$this->create();
if($this->save($data)) {
return true ;
}
}
}
function fetchdata() {
return $this->find('all', array('conditions' => array('Attendence.date' > '2014-04-01',
'AND' => array('Attendences.date' < '2014-04-21'),
)));
}
}
My Controller
class EmployeesController extends AppController {
public $uses = array('Employee', 'Attendence', 'InsertDate');
public function add()
{
if($this->Employee->add($this->request->data)==true){
$this->redirect(array('action'=>'index'));
}
}
public function index(){
$this->set('employees',$this->Employee->Fetch());
$this->set('attendence',$this->Attendence->fetchdata());
$this->set('dates',$this->InsertDate->fetchdate());
}
}
My View
<div class="index">
<table>
<thead>
<th>Num</th>
<th>Employee</th>
<th>Salary/Hour</th>
<th>Start Date</th>
<th>End Date</th>
<th>Total Hour</th>
<th>Total Salary</th>
</thead>
<?php
$id = 0;
foreach($employees as $e):?>
<? $id++ ?>
<tr>
<td><?php echo $e{'Employee'}{'id'} ?></td>
<td><?php echo $e['Employee']['firstname'], $e['Employee']['lastname'] ?></td>
<td style="text-align:center"><?php echo $e['Employee']['salary'] ?></td>'
<?php foreach($dates as $d):?>
<td><?php echo $d['InsertDate']['start_date'] ?></td>
<td><?php echo $d['InsertDate']['end_date'] ?></td>
<?php
$total_hours = 0;
foreach ($attendence as $et){
$ts1 = strtotime($et['Attendence']['in_time']);
$ts2 = strtotime($et['Attendence']['out_time']);
$diff = abs($ts1 - $ts2) / 3600;
$total_hours += number_format($diff,2);
}
//Total hours
echo '<td style="text-align:center">'.$total_hours.'</td>';
//Total Salary
echo '<td style="text-align:center">'.$total_hours*$e['Employee']['salary'].'</td>';
?>
<?php endforeach; ?>
<?php endforeach; ?>
</tr>
</table>
</div>
A programmer friend of mine gave me a solution. But I dont know how to implement in CAKEPHP
I am updating the solution also
Look at here :
$total_hours = 0;
foreach ($attendence as $et){
$ts1 = strtotime($et['Attendence']['in_time']);
$ts2 = strtotime($et['Attendence']['out_time']);
$diff = abs($ts1 - $ts2) / 3600;
$total_hours += number_format($diff,2);
}
The code shows you that there is an array. the array contains (attendance id and in_time and out_time in each point).
The Important thing is you should check how you fill this array.
In the above foreach that you generate the table by $employees array , you have the (employee_id) wich name (id) here
So you should write a new query in your view!!!In the middle of your first foreach and before second foreach
before this line :
$total_hours = 0
You have to write a query and fetch data from DB like this :
//SELECT * FROM attendences
WHERE attendences.date > '2014-04-23' AND attendences.date < '2014-04-30'
AND id=$e['Employee']['id'] // is your employee_id in your first array.
So when you fetched data , You have a new array named "$attendence"
Then , your second foreach(which calculates the salary and total hours) should work correctly
