Can anyone help me with PHPExcel?
I have this code...
<?php
session_start();
include 'dbconnect.php';
date_default_timezone_set("Europe/Rome");
if (!isset($_SESSION['user'])) {
header("Location: index.php");
}
$query = mysql_query("SELECT * FROM partner1 WHERE uid=" . $_GET['id']);
while ($userRow1 = mysql_fetch_assoc($query)) {
/** Error reporting */
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);
date_default_timezone_set('Europe/Rome');
if (PHP_SAPI == 'cli')
die('This example should only be run from a Web Browser');

When I try to read and download my database data to excel format I get a blank page and no download.
I don't get any error on this. I don't know what to do lol

Answer 1

Obvious problems (just wading through this wall of code)
if(!isset($_SESSION['user']))
{
header("Location: index.php");
}
will still continue executing the rest of the code
You're including PHPExcel, creating a new PHPExcel object, and sending the response to the browser for every single row that you iterate in the while $userRow1 = mysql_fetch_assoc($query)) loop.... I'm assuming that you really want each row to be written to the same file
EDIT
Trying to keep the answer simple, rather than a wall of code, your structure should be something like:
include 'dbconnect.php';
/** Include PHPExcel */
require_once dirname(__FILE__) . '/Classes/PHPExcel.php';
// Create new PHPExcel object
$objPHPExcel = new PHPExcel();
$query=mysql_query("SELECT * FROM partner1 WHERE uid=".$_GET['id']);
while($userRow1 = mysql_fetch_assoc($query)) {
// Add some data
$objPHPExcel->setActiveSheetIndex(0)
->setCellValue('A1', 'Codice Op')
.....
;
}
// Redirect output to a client’s web browser (Excel5)
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="01simple.xls"');
header('Cache-Control: max-age=0');
// If you're serving to IE 9, then the following may be needed
header('Cache-Control: max-age=1');
// If you're serving to IE over SSL, then the following may be needed
header ('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past
header ('Last-Modified: '.gmdate('D, d M Y H:i:s').' GMT'); // always modified
header ('Cache-Control: cache, must-revalidate'); // HTTP/1.1
header ('Pragma: public'); // HTTP/1.0
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('php://output');
exit;
Also note that the mysql extension is deprecated in PHP, you should really be using mysqli or PDO with prepared statements/bind variables to protect your script against SQL injection
