If you have the following error at 56:55 call_user_func(): Argument #1 ($callback) must be a valid callback, non-static method app\controllers\SiteController::handleContact() cannot be called statically You have to make some changes in Router class. During the time of making this framework PHP version was allowing calling non-static method statically, but later it was changed. Here is fix... At 31:07 instead of calling call_user_func($callback) directly, we need to create an instance of the controller first. if (is_array($callback)) { $callback[0] = new $callback[0]; } return call_user_func($callback);

[@TheCodeholic]

Does your controller have correct namespace? Try to put \ in front of app\controller\SiteController

[@TheCodeholic]

@Đinh Như Khang I mean in index.php

[@TheCodeholic]

You have something wrong in either index.php or in SiteController

[@blessdarah1256]

@Đinh Như Khang I also have this type of problem. The temporal solution was to make the function in the controller static. I'm stilling looking of a good fix to work without having to make all controller functions static.

[@blessdarah1256]

This solution works perfectly fine. Tested and it's working.

Just finished Part 1. I really learned quite a bit. Some constructive feedback: - Maybe breaking the video down into shorter parts. There were a few points where I felt the video could have ended and a new one started. - For those not using PHPStorm, maybe clarifying when PHPStorm automagically adds something. - Maybe a little less jumping around; can be confusing for novices. Great job and extremely thorough explanation! Thank you!

[@arnavchandra]

In addition it would be great to install sentinel native or having sentinel native installed in any MVC other than Laravel ... in case just an idea... u can carry forward this same MVC integrating it with Twig and Sentinel it would be awesome... We can have Twig in one part and Sentinel in another ...
