Make yii enviroment

Configure DB and folder structure

config/ -> configuration files db.php - database configuration file, web.php - yii application configuration file

runtime/ -> log files, temp files

controllers/ -> controller files

models/ -> model files

views/ -> viewer templates and viewers

web/ -> assets - js and css files, index.php entry point to the yii application robots.txt - search engine

vendor/ -> composer modules including yiisoft self

models can be either directly setup with database command or use migration files

Model

db.php - set TablePrefix
construct model class:

class Test extends ActiveRecord
{
    public static function tableName()
    {
        return "{{%test}}" # test is the table name, actually the real table name is prefix_test
    }
}

query methods:

$this->find()->one();
$this->findOne();
$this->findAll();
$this->find()->where()

Views

boolean checkbox

<div class="remember">
    <input id="remember-me" type="checkbox" />
    <label for="remember-me">Remember Me</label>
</div>

can be written to

<?= $form->field($model, 'rememberMe')->checkbox([
    'id' => 'remember-me',
    'template' => '<div class="remember">{input}<label for="remember-me">Remember Me</label></div>
])

furthermore all fields can use same template

<?php $form=ActiveForm::begin([
    'fieldConfig' => [
        'template' => '{input}'
    ]
])

disable the layout

$this->layout = false; # set public variable public $layout = false;
return $this->renderPartial(‘index’, array(‘data’=>data))

assets
asset / static files should be copied to web/assets

make own layout

base template layout with <?=$content ?> for template rendering.

$this->layout = ‘myLayout’; # public $layout = ‘myLayout’;

use gii to create new module

for example, to make backend admin module for shopping website. and add modules in config/web.php

modules/controllers, modules/views

set default route

make the default route setting in web.php, add:

‘defaultRoute’ => ‘myControllerName’
