WordPress - Hide Actual Download Url

WordPress customized many way .But when a user download your file from your blog. It happen to appear link like this " www.Yourwebsite.com/wp-content/uploads/2013/06/download.zip" It's showing the url link to your visitors where your file is located. Its giving security problem to your blog. You have to hide the actual url of your files location.

I tried to use a method to hide the download location and allow all downloads from the url like this  "www.yoursite.com/download/?m=d4wef4vbsdfv4334v45g6hg4rbvwq4vv.zip"

otherwise like this "www.yoursite.com/downloads/"

This is most secure because no one is going to know your file location. First thing we need to create a file namely "download.php" and link  it your wordpress theme file or plugin file.

go to your admin panel and under that pages and Add New then crreate page namely download and make sure the url look like above said one. Then add it to your download page  

['donload_page']

we have to send a file name or post id to downloads.php and make it downloadable by your user. So here i will use post id to make download.

Goto your download.php file and paste the following code in it.

<?php 

ob_start();

function download_link_page(){

    global $wpdb , $current_user , $wp_roles;

    get_currentuserinfo();

    $setting = wp_upload_dir();

    $allowed_referred = "";

    $base_dir = $setting['basedir'];

    $log_downloads = true;

    $down_stat_table = $wpdb->prefix.'download_stat';

    if(!empty($settings)) {

        foreach($settings as $setting) {

            if(rtrim($setting->allowed_referred) != "")

                $allowed_referred =  $setting->allowed_referred;

           

            if(rtrim($setting->base_dir) != "")

                $base_dir =  $setting->base_dir;

            if($setting->log_downloads == "0")

                $base_dir =  false;

        }

    }

The above code can help you to create a secure download and hide your actual file location .Here we need to send post id to create download. So create form like this into your loop.php or single .php

<form method="post" action="<?php echo site_url('download'); ?>" >

<input type="hidden" name="item_number" value="<?php echo $post->ID; ?>" >

<input type="submit" value="Download" class="class-btn" name="submit"> 

</form> 

That's all  to create secured download manager for your files. Leave a comment here as your views of suggestions and feedbacks.
