No data from the database after the files downloaded - mysql

Question

I want to display the data on a particular condition of the table after the user enters the data you want to display.
But always failed to display the data. I am confused where the fault lies.
It looks like the variable $thn = $ _POST['thn'], $bln = $ _POST['bln'], $periode = $ _POST['periode'] is empty.
please help.
I have four files.
Here the codes:
1.absen_xls.php:
<?php
include '../../inc/inc.koneksi.php';
ini_set('display_errors', 1); ini_set('error_reporting', E_ERROR);
include '../../excel/PHPExcel.php';
include '../../excel/PHPExcel/IOFactory.php';
$table = 'absen_karyawan';
$bln = $_POST['bln']; //this not work, I don't know why?
$thn = $_POST['thn']; //this not work, I don't know why?
$periode = $_POST['periode']; //this not work, I don't know why?
$where = "WHERE tahun = '$thn' AND bulan = '$bln' AND periode = '$periode'";
// Create new PHPExcel object
$objPHPExcel = new PHPExcel();
$sql = "SELECT namakaryawan,tahun,bulan,periode,absen FROM $table $where";
$query = mysql_query($sql);
// bold
$objPHPExcel->getActiveSheet()->getStyle("A2:C2")->applyFromArray(array("font" => array( "bold" => true)));
// Add some data
$objPHPExcel->setActiveSheetIndex(0)
->setCellValue('A2', 'No')
->setCellValue('B2', 'Nama')
->setCellValue('C2', 'Kehadiran');
$baris = 3;
$no = 0;
while($row=mysql_fetch_array($query)){
$no = $no +1;
$objPHPExcel->setActiveSheetIndex(0)
->setCellValue("A$baris", $no)
->setCellValue("B$baris", $row['namakaryawan'])
->setCellValue("C$baris", $row['absen']);
$baris = $baris + 1;
}
//border
$border = $baris - 1;
$styleArray = array(
'borders' => array(
'allborders' => array(
'style' => PHPExcel_Style_Border::BORDER_THIN
)
)
);
$objPHPExcel->getActiveSheet()->getStyle('A2:C'.$border)->applyFromArray($styleArray);
unset($styleArray);
//width
$objPHPExcel->getActiveSheet()->getColumnDimension("A")->setWidth(5);
$objPHPExcel->getActiveSheet()->getColumnDimension("B")->setWidth(20);
$objPHPExcel->getActiveSheet()->getColumnDimension("C")->setWidth(15);
//align center
$objPHPExcel->getActiveSheet()->getStyle('A2:C'.$border)->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
// Rename sheet
$objPHPExcel->getActiveSheet()->setTitle('Absen');
// Set active sheet index to the first sheet, so Excel opens this as the first sheet
$objPHPExcel->setActiveSheetIndex(0);
// Redirect output to a client’s web browser (Excel5)
header('Content-Type: application/vnd.ms-excelformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="absen.xlsx"');
header('Cache-Control: max-age=0');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('php://output');
exit;
?>
2.ajax.php:
// JavaScript Document
$(document).ready(function(){
$(function(){
$('button').hover(
function() { $(this).addClass('ui-state-hover'); },
function() { $(this).removeClass('ui-state-hover'); }
);
});
$("#tampil_data").load('modul/lap-absen/tampil_data.php');
$("#print").click(function(){
var thn = $("#thn").val();
var bln = $("#bln").val();
var periode = $("#periode").val();
cetakabsen(thn,bln,periode);
});
function cetakabsen(c1,c2,c3){
var thn = c1;
var bln = c2;
var periode = c3;
$.ajax({
type : "POST",
url : "modul/lap-absen/absen_xls.php",
data : "thn="+thn+"&bln="+bln+"&periode="+periode,
success : function(data){
window.open('http://localhost/gudang/modul/lap-absen/absen_xls.php');
}
});
}
});

Answer 1

Change your function to this one:
function cetakabsen(c1,c2,c3){
var thn = c1;
var bln = c2;
var periode = c3;
var data = "thn="+thn+"&bln="+bln+"&periode="+periode;
window.open('http://localhost/gudang/modul/lap-absen/absen_xls.php?'+data);
}
And receive your values like this in absen_xls.php:
$bln = mysql_real_escape_string($_GET['bln']);
$thn = mysql_real_escape_string($_GET['thn']);
$periode = mysql_real_escape_string($_GET['periode']);
PS: Go for mysqli or PDO, dont use the mysql extension.
