dlb's Send-A-Link for WordPress

dlb’s Send-A-Link allows visitors to send someone an email containing a link to the post or page.

Key features include:

Show visitors a link (icon and/or text) to send an email by adding a function call to your templates or a shortcode to your pages/posts.

The input form, confirmation page, and email message are all based on easily modifiable HTML templates.

Spam protection includes CAPTCHA verification and limiting any given IP address to two messages per minute.

Send-A-Link loads fast because code is compact and does not use jQuery.

Send-A-Link uses Javascript/AJAX for fast, inobtrusive form handling, but it degrades gracefully to provide full functionality to clients without Javascript.

Built and tested on WordPress v3.5.1; although it might work on earlier versions, it has not been tested on them.

dlb’s Send-A-Link code is heavily commented, especially regarding WordPress plugin interfaces and AJAX features. This makes it a suitable starting point for novice developers to explore their own programming interests. I have attempted to make the code very understandable. However, I do not claim this to be model code because I am not an experienced developer myself. In fact, I would greatly appreciate constructive criticism.

In the future, I plan to release new versions with the following features, in approximately this order:

Privacy reassurance that email addresses are not stored, but IP’s are

Make the “send another message” link consistently re-display form with fields pre-filled
