On Click File Download, On Success Redirect To Another Page Using AJAX

In my WordPress project, my Download button containing a .zip file, which onClick should be downloaded. So the HTML producing is: >Download</a>

Above can be url link to download and below will be php code in download.php

//code to update download count (UPDATE tbl_dwn SET total = total + 1)
//below is code to download (hope you know it)
$zipName = $_GET['file']; //here you've to specify the absolute path to the download.zip file
header("Content-type: application/zip");
header("Content-Disposition: attachment; filename=".$zipName."");
header("Content-length: " . filesize($zipName));
header("Pragma: no-cache"); 
header("Expires: 0");
readfile($zipName);

Try out this and let me know if you've any problem.

Solution 2:

Try this,

Will take you to another page

success: function (data) {
    window.location.href = site.url + "/download-success?fid="+ id;
}

Will take you to another page in the new window

success: function (data) {
    window.open('site.url + "/download-success?fid="+ id');
}
