On the SitePoint PHP blog today Lukas White has a new tutorial showing you how to handle incoming emails from SendGrid (well, pulled from SendGrid) and translate them into posts for your blog or site.

In this article, I’m going to look at how you might implement an email-to-post feature, using SendGrid. SendGrid is a service for sending email – usually in bulk, but they also offer a less well-publicized feature for handling incoming email. SendGrid can be configured to handle all incoming messages for a given domain by pinging a URI of your choosing, and by implementing a simple webhook, you can act on the incoming mail accordingly.

He bases the simple example off of the Slim framework, creating a structure with a basic database for users and posts. He then goes through the SendGrid interface, pointing out where you add the hostname and URL to call back when a new email comes in. He includes the code to create the callback functionality that accepts the POST request coming from SendGrid. This is then validated and inserted into the database to be pulled out later by the "posts" page. There's also a bit about saving images (or other files) that come in as attachments to the email.
