hi, i coded some basic file downloader (for word, excel, powerpoint,
pdf, etc files). My question is, do i have to use a special header
before sending the file to the user in the http request? this is the
code:
<?php
$id = $_GET['id'];
if(!is_numeric($id)) {
header('Location: '.$_SERVER['HTTP_REFERER']);
die();
}
# Verify that file linked to the ID exists
$sql = 'SELECT * FROM files WHERE id = '.$id;
$rs = &$cnn->Execute($sql);
if (!$rs->EOF) {
# File exists
$record = array();
# Increments download-times count
$record['downloads'] = $rs->fields['downloads']+1;
$sql = $cnn->GetUpdateSQL($rs, $record);
$cnn->Execute($sql);
header('Location: /files/'.basename($rs->fields['filename']));
die();
} else {
# File doesn't exist
header('Location: '.$_SERVER['HTTP_REFERER']);
die();
}
?>
As you can see, im only using header to redirect the user to the FILE
itself. Is that ok? or do i have to set some kind of binary header?
Thanks,
Andres
