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 so we all can quickly setup the yii-basic-demo.

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 (like DB login, translations etc) which must be implemented in the most of web projects so I will focus on them. Plus I will talk about GitLab.

Prerequisities ¶

Skip this paragraph if you know how to run your Yii demo project...

I work with Win10 + XAMPP Server so I will expect this configuration. Do not forget to start the server and enable Apache + MySQL in the dialog. Then test that following 2 URLs work for you

• http://localhost/
• http://localhost/phpmyadmin/

You should also download the Yii basic demo application and place it into the htdocs folder. In my case it is here:

• C:\xampp\htdocs

And your index.php should be here:

• C:\xampp\htdocs\basic\web\index.php

If you set thing correcly up, following URL will open your demo application. Now it will probably throw an exception:

• http://localhost/basic/web/

The Exception is removed by enterinng any text into attribute 'cookieValidationKey' in file:

• C:\xampp\htdocs\basic\config\web.php

Dont forget to connect Yii to the DB. It is done in file:

• C:\xampp\htdocs\basic\config\db.php

... but it should work out of the box ...

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 `yii2basic` 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, views and controller. The URL will probably be

• http://localhost/basic/web/index.php?r=gii.
