Create date range report column using codeigniter 3 excel - php

Question

I want to create export file date-range report using ci.
views.php
<div class="form-group row">
<label for="attn_date" class="col-sm-4 col-form-label">From</label>
<div class="col-sm-8">
<input type="date" class="form-control" id="attn_from" name="attn_from">
<?= form_error('attn_from'); ?>
</div>
</div>
<div class="form-group row">
<label for="attn_date" class="col-sm-4 col-form-label">To</label>
<div class="col-sm-8">
<input type="date" class="form-control" id="attn_to" name="attn_to">
<?= form_error('attn_to'); ?>
</div>
</div>
<div class="form-group row">
<label for="daily_export_file" class="col-sm-4 col-form-label">Export Data</label>
<div class="col-sm-8">
<?= form_dropdown('export_file', ['report' => 'Report'], set_value('export_file'), 'class="form-control" id="export_file"'); ?>
<?= form_error('export_file'); ?>
</div>
</div>
controller.php
$querydata = $this->db->query("select a.*, b.* from db_attn a
LEFT JOIN tbl_wrkhour b
ON b.id_wrkhour = a.wrk_hour WHERE attn_date between '". $this->input->post('attn_from')."'
AND '". $this->input->post('attn_to')."'order by attn_date desc")->result();
$spreadsheet = new PhpOffice\PhpSpreadsheet\Spreadsheet();
$sheet_name = $spreadsheet->getActiveSheet()->setTitle("Attendance Report");
$sheet = $spreadsheet->getActiveSheet();
$highestRow = $sheet->getHighestRow();
$highestColumm = $sheet->getHighestColumn();
$dataattn = $querydata;
$sheet->setCellValue('A5', 'No');
$sheet->setCellValue('B5', 'Employee Name');
$sheet->setCellValue('C5', 'Date');
$sheet->setCellValue('D5', 'Detail');
$no = 1;
$rowx = 6;
foreach ($dataattn as $rowattn) {
$sheet->setCellValue('A' . $rowx, $no++);
$sheet->setCellValue('B' . $rowx, $rowattn->emp_name);
$sheet->setCellValue('C' . $rowx, $rowattn->date);
$sheet->setCellValue('D' . $rowx, $rowattn->attn_detail);
}
I've successfully show date range of all employee details. How to transpose the detail of each date?
current view in my export excel file:
No
Employee Name
Date
Detail
1
aaaa
03-01-2023
Present
2
bbbb
03-01-2023
leave
3
cccc
03-01-2023
late
4
aaaa
04-01-2023
Present
5
bbbb
04-01-2023
Present
6
cccc
04-01-2023
Present
expected change:
No
Employee Name
03-01-2023
04-01-2023
next column date range
1
aaaa
Present
Present
next
2
bbbb
leave
Present
next
3
cccc
late
Present
next
Any idea? Please help...

Answer 1

You can probably get that from SQL directly
select
no,
emp_name,
case
when exists (select user was present on time on 03-01-2023) then 'Present'
when exists (select user was present late on 03-01-2023) then 'Late'
else 'Absent'
end as '03-01-2023',
....

Answer 2

create a helper array, fill it in foreach function with rules and colums, then set this array to $dataattn.
