Yet another item that I’ve been looking for and there wasn’t a simple solution.   I’ve actually been looking at this for a while then I just realized it would be really simple to write a filter.

If you own wordpress and you want to make sure that your users login/register before downloading .zip files, or any files if you want to customize it, the check this out.

• Protects your links, promotes website user-base growth
• Isn’t more than you need, no file management just pure href swapping

How to install

1. Take the following function a put it in your formatting.php file located in wp-admin
2. go into default-filters.php and put this around line 111  add_filter(’the_content’, ‘linkcheck’);
3. replace the “http://www.hawkenterprises.org” with the location of your login file.

function linkcheck($text){
if(!is_user_logged_in()){
return preg_replace(’/<a\shref=\”([^\"]*.zip)\”>(.*)<\/a>/’,'<a href=”http://www.hawkenterprises.org/wp-login.php”>$2</a> (Requires Login)’,$text);
}else{
return $text;
}
}

That’s it,   We will probably make a wordpress plugin out of it soon but this should help all you who want to force users to register.
