Drupal Download Wait Module - Make users wait before every download

Drupal module to make user wait before download of any file

My requirement

I want to every visitor to wait before downloading any file. Also I don't want the search engines to index the download file. I earn from ads so the more visitors see them, the better for me.

How to do it

It is best done using POST form submission, which will make search engines to automatically stop there. This POST data will contain the file to download, wait delay the user will need to wait before downloading the file.

Functionality

You can find actual implementation here.
To present a file for download, first install the anu_download_wait module. I use brtDownloadPostRequest.pl file to quickly generate the "Download" button. It looks something like:

<form method="post" action="http://127.0.0.1/bookrailticket/downloadsbrt/90n-brt-download-file-now" class="com_download_showpage_form">
<input type="hidden" value="http://127.0.0.1/bookrailticket/200812-48539a7b9-indian-rail-route-map-p09" name="anu_download_file_link" />
<input type="hidden" value="1" name="anu_download_wait_delay_factor" />
<input type="hidden" value="Indian Railways Route Map" name="anu_download_file_title" /> <input type="submit" title="Press this button to download the document" value="Download" class="submitBtn1" />
</form>

Mind you it contains following changeable values:

• anu_download_file_link : Set it to wherever the download is present. After wait is over, visitor will be taken to this page
• anu_download_wait_delay_factor(optional): How many seconds the visitor will wait( 1- 300 secs). Any other value will have it reset to 45 second in the module
• anu_download_file_title: This title will be shown in the download page.

There is also a text box in the download area where user can enter his/her email id. I'm simply saving the email in a txt file in the module directory. Not doing anything else.

Javascript Issues

If javascript is disabled then the download button is shown enabled. So it will work by default. Also unless jquery & Drupal library is fully loaded the "Download" button will show as enabled and as soon as it is fully loaded, the javascript code will hide it and re-enable it after the wait period.

Redirect Feature

There is another redirect feature I've added is that if in the link the file is present in within your site then you can create a file in the same folder with the same name but with ".redirect" suffix added and put the redirected url in it, then the download will be redirect to this location. White space is not a problem in .redirect file.
This is because mine is shared hosting and download of big files will choke my account and also all files should be present in my site as a backup by default.
So if anu_download_file_link is set to "http://www.example.com/sites/default/files/abc.pdf" then just upload this file in say DropBox, Hotfile etc and put that link in the file: sites/default/files/abc.pdf.redirect in your site. So even if you remove this redirect file your downloads keep working!
