Since
3.1.0

EnvAttributeParserBehavior can be applied to models with attributes that can be set to either environment variables ($VARIABLE_NAME) or aliases (@aliasName).

php
public function behaviors()
{
    return [
        'parser' => [
            'class' => EnvAttributeParserBehavior::class,
            'attributes' => ['attr1', 'attr2', '...'],
        ],
    ];
}

Public Properties ​

PropertyDescription
attributesstring[], callable[] – The attributes names that can be set to environment variables ($VARIABLE_NAME) and/or aliases (@aliasName).
owneryii\base\Model

attributes ​

Type
string[], callable[]
Default value
[]

The attributes names that can be set to environment variables ($VARIABLE_NAME) and/or aliases (@aliasName).

If the raw (unparsed) attribute value can’t be obtained from the attribute directly ($model->foo), then the attribute name should be specified as an array key instead, and the value should be set to the raw value, or a callable that returns the raw value. For example:

php
'attributes' => [
    'foo' => '$FOO',
    'bar' => function() {
        return $this->_bar;
    },
],

afterValidate() ​

Restores the original attribute values after validation occurs.

beforeValidate() ​

Replaces attribute values before validation occurs.

View source

events() ​

Declares event handlers for the owner's events.

Child classes may override this method to declare what PHP callbacks should be attached to the events of the owner component.

The callbacks will be attached to the owner's events when the behavior is attached to the owner; and they will be detached from the events when the behavior is detached from the component.

The callbacks can be any of the following:

  • method in this behavior: 'handleClick', equivalent to [$this, 'handleClick']
  • object method: [$object, 'handleClick']
  • static method: ['Page', 'handleClick']
  • anonymous function: function ($event) { ... }

The following is an example:

php
[
    Model::EVENT_BEFORE_VALIDATE => 'myBeforeValidate',
    Model::EVENT_AFTER_VALIDATE => 'myAfterValidate',
]
