Disable opening of popup when downloading a file

[admin]

I am creating a wordpress page that allows users to downloads a zip file after 5 secs. In it, I am calling a second page and pass POST parameters ( zip id :: to fetch zip path). The page is called but always as a pop up. I am looking for a <strong>clean download options, where without opening tabs or new window, download begins</strong>. Bypasses popup - blockers also.

I have tried two methods

A) Method 1 ( Jquery Post)

$.post(
        "<?php echo get_permalink(get_page_by_title('Download Page')); ?>",
        {attachment_path: "<?php echo $attachment[0]->ID ; ?>"
    }

B) Method 2 (Submitting a form)

$( '<form action="" method="post" target="_parent" class="hide">
       <input type="hidden" name="attachment_path" value="<?php echo $attachment[0]->ID ; ?>" />
       <input type="submit" name="submit" value="submit" id="target-counter-button"/>
    </form>'
   ).submit();

<strong>Edit</strong>

1) Looking for a POST method to implement the logic

2) Due to server restrictions, direct access to *.php files and *.zip files have been blocked

3) Parent Download Page should remain open in the process

Looking for a expert advice on this issue.

Thanks
