Introduction

Craft 3 coming into focus.
We've had 3 Craft 3 version releases since last issue. We're now at version 3.0.2937. We're getting Multi-site support. Nice.
There are a number of plugins, and other stories to check out including a number of links that come from a Slack discussion regarding HTML sent from Craft.
If you've got a link to share with me, be sure to get in touch. Want to sponsor an issue? By all means, get in touch. :-)
Let's hit the links.

Why "Craft::$app" in Craft 3.
If you're wondering about Craft 3's use of Craft::$app
, Brandon mentioned this in Slack on Sept 12.
...the reason Craft 3 does
Craft::$app
instead ofcraft()
is namespaces. In Craft 2 everything was in theCraft
namespace so we could just put thecraft()
function in there and everything could access it. But with everything in its own namespaces in Craft 3, that wouldn't be the case. PHP didn't make it possible to import a function from a different namespace until 5.6, and originally Yii 2/Craft 3 supported back to 5.4. Yii 2.1 is going to require 5.6 though, and we've already bumped Craft's requirement to 5.6 in preparation of that, so it's doable now.

Up and Running With Craft CMS (...a different one)
You may think you've heard of this course before, but this is not Mijingo course you're thinking of. Kezz Bracey, writing for TutsPlus, has created a own course and named it the exact same name as the Mijingo course. Too bad about the name confusion, but it's good to have the resource.

Kezz Bracey followed up the TutsPlus mentioned above with another course dedicated to building landing pages with Craft.

I do not "sprechen sie Deutsch" so I'm cutting and pasting the description below.

Connect to MySQL Remotely (with ServerPilot)
This link was mentioned in a discussion about methods of connecting to remote databases.
"Basically this works like it's running mysql locally but sends the results over a standard ssh connection to your database client - looks like Navicat can do this too.
In a nutshell you give it you ssh username and password (or better, private key file) - and the normal DB login details (like the ones you have in db.php) - and away it goes over ssh."
Don't Use "Else"
