Intro ¶

Skip this paragraph if you are in hurry :-) ... 8 years ago I started these two tutorials for Yii 1:

• https://www.yiiframework.com/wiki/250/yii-for-beginners
• https://www.yiiframework.com/wiki/462/yii-for-beginners-2

... and today I am beginning with Yii 2 so I will also gather my snippets and publish them here. They are meant maily for me, but also for other beginners. I have some experiences with Yii 1, but I havent used Yii for almost 5 years so many things are new for me again. Plus I was suprised that the Yii 2 demo application does not contain some basic functionalities which must be implemented in the most of web projects so I will focus on them. Plus I will talk about GitLab.

User management + basic SQL commands ¶

To create DB with users, use following command. I recommend charset utf8_unicode_ci (or utf8mb4_unicode_ci) as it allows you to use more international characters.

CREATE DATABASE IF NOT EXISTS `yii-demo-db` DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci;

CREATE TABLE IF NOT EXISTS `user` (
  `id` INT NOT NULL AUTO_INCREMENT,
  `username` VARCHAR(45) NOT NULL,
  `password` VARCHAR(60) NOT NULL,
  PRIMARY KEY (`id`))
ENGINE = InnoDB;

INSERT INTO `user` (`id`, `username`, `password`) VALUES (NULL, 'user01', '0497fe4d674fe37194a6fcb08913e596ef6a307f');

If you must use MyISAM instead of InnoDB, just change the word InnoDB into MYISAM.

Then use GII to generate model and controller. The URL will probably be http://localhost/basic/web/index.php?r=gii.
