I am trying to put a XML file from MySQL database to a zip archive before downloading. I am able to create zip file but Windows is giving error while opening it.
error msg: window cannot open the foler. filename.zip is invalid
Here is my code:
<?php
if(isset($_GET['id']))
{
$id = intval($_GET['id']);
if($id <= 0) {
die('The id is invalid!');
}
else
{
// Connect to the database
$dbLink = new mysqli('localhost', 'root', 'root', 'db');
if(mysqli_connect_errno()) {
die("MySQL connection failed: ". mysqli_connect_error());
}
$zip = new ZipArchive();
$filename = "export_".date('Y.m.d H.i').".zip";
if ($zip->open($filename, ZIPARCHIVE::CREATE | ZIPARCHIVE::OVERWRITE) !== true)
{
echo "Cannot Open for writing";
}
$zip->addEmptyDir('Section');
$query = "SELECT name,data FROM file_section WHERE id ='$id'";
$result = $dbLink->query($query);
if($result->num_rows == 1)
{
// Get the row
$row = mysqli_fetch_array($result);
}
while($row = mysql_fetch_array($result))
{
$zip->addFile($row['data'], "{$row['name']}.xml");
}
$zip->close();
header("Content-disposition: attachment; filename='.$filename'");
header('Content-type: application/zip');
readfile($fileName);
}
// Free the mysqli resources
mysqli_free_result($result);
}
else {
echo "Error! Query failed: <pre>{$dbLink->error}</pre>";
}
mysqli_close($dbLink);
?>
P.S.: I have limited PHP knowledge.
