I am trying to write data from database to a downloadable excel sheet. The code is working in the sense that it downloads the file with the desired name. However if I open the Excel sheet the cells are empty and my data is not in the sheet.
Here is my code
require_once('include/connect_pdo.php');
$myschool = $_POST['country'];
$findschool = $conn->prepare("SELECT Query");
$findschool->execute();
$filename = "Name";
$file_ending = "xls";
//header info for browser
header("Content-Type: application/xls");
header("Content-Disposition: attachment; filename= $filename.xls");
header("Pragma: no-cache");
header("Expires: 0");
/*******Start of Formatting for Excel*******/
//define separator (defines columns in excel & tabs in word)
$sep = "\t"; //tabbed character
//start of printing column names as names of MySQL fields
for ($i = 0; $i < mysql_num_fields($result); $i++) {
echo mysql_field_name($result,$i) . "\t";
}
print("
");
//end of printing column names
//start while loop to get data
while($row = mysql_fetch_row($result))
{
$schema_insert = "";
for($j = 0; $j < mysql_num_fields($result); $j++)
{
if(!isset($row[$j]))
$schema_insert .= "NULL".$sep;
elseif ($row[$j] != "")
$schema_insert .= "$row[$j]".$sep;
else
$schema_insert .= "".$sep;
}
$schema_insert = str_replace($sep."$", "", $schema_insert);
$schema_insert = preg_replace("/
|
|
|/", " ", $schema_insert);
$schema_insert .= "\t";
print(trim($schema_insert));
print "
";
}
