Integrating with Easy Digital Downloads

Chad Butler · Jul 5, 2016 ·

Easy Digital Downloads is an incredibly popular plugin that allows you to create a digital product store using WordPress.

You can require users to be logged in to checkout in EDD, but that does not restrict a download link from being used when the user is not logged in. Restrictions can be put on the link in terms of number of times it can be downloaded and disable redownload, but that can lead to a poor user experience – being over protective can create problems for legitimate users while protecting what amounts to a “perceived” risk rather than real.

But you can integrate with WP-Members to force a user to be logged in to actually download the file. This way, even if the link is known and not expired, the user will be redirected to login if they attempt to download without being logged in.

Note: for best results in understanding this customization, it is best to create a test field exactly as described in this example and using the example scripts as they are written. Once you have it working, then you can move to creating this process for your specific field. Continue Reading →

Make MailChimp subscribe field a hidden field in the WP-Members registration form

Chad Butler · Mar 11, 2015 ·

Suppose you are using the WP-Members registration form essentially as an opt-in to your MailChimp list. Essentially, you want anyone who fills out the form to be added to the MailChimp opt-in process.

This requires you to have the MailChimp extension installed and a subscribe field set up and configured. This filter will take that field and make it a hidden field, essentially triggering the MailChimp opt-in process for all users. Continue Reading →
