Method Details

attributes() public method

Returns the list of all attribute names of the record.

public attributes ( ) : array
return	array	list of attribute names.

delete() public method

Deletes the record from the database.

public delete ( ) : integer \| boolean
return	integer \| boolean	the number of rows deleted, or `false` if the deletion is unsuccessful for some reason. Note that it is possible that the number of rows deleted is 0, even though the deletion execution is successful.

deleteAll() public static method

WARNING: If you do not specify any condition, this method will delete ALL rows in the table. For example, to delete all customers whose status is 3: php Customer::deleteAll([status = 3]);

public static deleteAll ( array $condition = null ) : integer
$condition	array	the condition that matches the records that should get deleted. Please refer to [[QueryInterface::where()]] on how to specify this parameter. An empty condition will match all records.
return	integer	the number of rows deleted

equals() public method

Two [[getIsNewRecord()|new]] records are considered to be not equal.

public equals ( static $record ) : boolean
$record	static	record to compare to
return	boolean	whether the two active records refer to the same row in the same database table.

find() public static method

The returned ActiveQueryInterface instance can be further customized by calling methods defined in ActiveQueryInterface before one() or all() is called to return populated ActiveRecord instances. For example, php find the customer whose ID is 1 $customer = Customer::find()->where(['id' => 1])->one(); find all active customers and order them by their age: $customers = Customer::find() ->where(['status' => 1]) ->orderBy('age') ->all(); This method is also called by [[BaseActiveRecord::hasOne()]] and [[BaseActiveRecord::hasMany()]] to create a relational query. You may override this method to return a customized query. For example, php class Customer extends ActiveRecord { public static function find() { use CustomerQuery instead of the default ActiveQuery return new CustomerQuery(get_called_class()); } } The following code shows how to apply a default condition for all queries: php class Customer extends ActiveRecord { public static function find() { return parent::find()->where(['deleted' => false]); } } Use andWhere()/orWhere() to apply the default condition SELECT FROM customer WHERE deleted`=:deleted AND age>30 $customers = Customer::find()->andWhere('age>30')->all(); Use where() to ignore the default condition SELECT FROM customer WHERE age>30 $customers = Customer::find()->where('age>30')->all();

public static find ( ) : yii\db\ActiveQueryInterface
return	yii\db\ActiveQueryInterface	the newly created [[ActiveQueryInterface]] instance.

findAll() public static method

The method accepts: - a scalar value (integer or string): query by a single primary key value and return an array containing the corresponding record (or an empty array if not found). - a non-associative array: query by a list of primary key values and return the corresponding records (or an empty array if none was found). Note that an empty condition will result in an empty result as it will be interpreted as a search for primary keys and not an empty WHERE condition. - an associative array of name-value pairs: query by a set of attribute values and return an array of records matching all of them (or an empty array if none was found). Note that ['id' => 1, 2] is treated as a non-associative array. This method will automatically call the all() method and return an array of [[ActiveRecordInterface|ActiveRecord]] instances. For example, php find the customers whose primary key value is 10 $customers = Customer::findAll(10); the above code is equivalent to: $customers = Customer::find()->where(['id' => 10])->all(); find the customers whose primary key value is 10, 11 or 12. $customers = Customer::findAll([10, 11, 12]); the above code is equivalent to: $customers = Customer::find()->where(['id' => [10, 11, 12]])->all(); find customers whose age is 30 and whose status is 1 $customers = Customer::findAll(['age' => 30, 'status' => 1]); the above code is equivalent to: $customers = Customer::find()->where(['age' => 30, 'status' => 1])->all();

public static findAll ( mixed $condition ) : array
$condition	mixed	primary key value or a set of column values
return	array	an array of ActiveRecord instance, or an empty array if nothing matches.

findOne() public static method

The method accepts: - a scalar value (integer or string): query by a single primary key value and return the corresponding record (or null if not found). - a non-associative array: query by a list of primary key values and return the first record (or null if not found). - an associative array of name-value pairs: query by a set of attribute values and return a single record matching all of them (or null if not found). Note that ['id' => 1, 2] is treated as a non-associative array. That this method will automatically call the one() method and return an [[ActiveRecordInterface|ActiveRecord]] instance. For example, php find a single customer whose primary key value is 10 $customer = Customer::findOne(10); the above code is equivalent to: $customer = Customer::find()->where(['id' => 10])->one(); find the first customer whose age is 30 and whose status is 1 $customer = Customer::findOne(['age' => 30, 'status' => 1]); the above code is equivalent to: $customer = Customer::find()->where(['age' => 30, 'status' => 1])->one();

public static findOne ( mixed $condition ) : static
$condition	mixed	primary key value or a set of column values
return	static	ActiveRecord instance matching the condition, or `null` if nothing matches.

getAttribute() public method

If this record is the result of a query and the attribute is not loaded, null will be returned.

getDb() public static method

Returns the connection used by this AR class.

public static getDb ( ) : mixed
return	mixed	the database connection used by this AR class.

getIsNewRecord() public method

Returns a value indicating whether the current record is new (not saved in the database).

public getIsNewRecord ( ) : boolean
return	boolean	whether the record is new and should be inserted when calling [[save()]].

getOldPrimaryKey() public method

This refers to the primary key value that is populated into the record after executing a find method (e.g. find(), findOne()). The value remains unchanged even if the primary key attribute is manually assigned with a different value.

public getOldPrimaryKey ( boolean $asArray = false ) : mixed
$asArray	boolean	whether to return the primary key value as an array. If true, the return value will be an array with column name as key and column value as value. If this is `false` (default), a scalar value will be returned for non-composite primary key.
return	mixed	the old primary key value. An array (column name => column value) is returned if the primary key is composite or `$asArray` is true. A string is returned otherwise (`null` will be returned if the key value is `null`).

getPrimaryKey() public method

Returns the primary key value(s).

public getPrimaryKey ( boolean $asArray = false ) : mixed
$asArray	boolean	whether to return the primary key value as an array. If true, the return value will be an array with attribute names as keys and attribute values as values. Note that for composite primary keys, an array will always be returned regardless of this parameter value.
return	mixed	the primary key value. An array (attribute name => attribute value) is returned if the primary key is composite or `$asArray` is true. A string is returned otherwise (`null` will be returned if the key value is `null`).

getRelation() public method

A relation is defined by a getter method which returns an object implementing the ActiveQueryInterface (normally this would be a relational ActiveQuery object). It can be declared in either the ActiveRecord class itself or one of its behaviors.

public getRelation ( string $name, boolean $throwException = true ) : yii\db\ActiveQueryInterface
$name	string	the relation name, e.g. `orders` for a relation defined via `getOrders()` method (case-sensitive).
$throwException	boolean	whether to throw exception if the relation does not exist.
return	yii\db\ActiveQueryInterface	the relational query object

hasAttribute() public method

Returns a value indicating whether the record has an attribute with the specified name.

public hasAttribute ( string $name ) : boolean
$name	string	the name of the attribute
return	boolean	whether the record has an attribute with the specified name.

insert() public method

Usage example: php $customer = new Customer; $customer->name = $name; $customer->email = $email; $customer->insert();

public insert ( boolean $runValidation = true, array $attributes = null ) : boolean
$runValidation	boolean	whether to perform validation (calling [[\yii\base\Model::validate()\|validate()]]) before saving the record. Defaults to `true`. If the validation fails, the record will not be saved to the database and this method will return `false`.
$attributes	array	list of attributes that need to be saved. Defaults to `null`, meaning all attributes that are loaded from DB will be saved.
return	boolean	whether the attributes are valid and the record is inserted successfully.

isPrimaryKey() public static method

Returns a value indicating whether the given set of attributes represents the primary key for this model

public static isPrimaryKey ( array $keys ) : boolean
$keys	array	the set of attributes to check
return	boolean	whether the given set of attributes represents the primary key for this model

link() public method

The relationship is established by setting the foreign key value(s) in one record to be the corresponding primary key value(s) in the other record. The record with the foreign key will be saved into database without performing validation. If the relationship involves a junction table, a new row will be inserted into the junction table which contains the primary key values from both records. This method requires that the primary key value is not null.

public link ( string $name, static $model, array $extraColumns = [] )
$name	string	the case sensitive name of the relationship, e.g. `orders` for a relation defined via `getOrders()` method.
$model	static	the record to be linked with the current one.
$extraColumns	array	additional column values to be saved into the junction table. This parameter is only meaningful for a relationship involving a junction table (i.e., a relation set with [[ActiveQueryInterface::via()]]).

populateRelation() public method

Note that this method does not check if the relation exists or not.

Since: 2.0.8

public populateRelation ( string $name, yii\db\ActiveRecordInterface \| array \| null $records )
$name	string	the relation name, e.g. `orders` for a relation defined via `getOrders()` method (case-sensitive).
$records	yii\db\ActiveRecordInterface \| array \| null	the related records to be populated into the relation.

primaryKey() public static method

Note that an array should be returned even when the record only has a single primary key. For the primary key **value** see ActiveRecordInterface::getPrimaryKey instead.

public static primaryKey ( ) : string[]
return	string[]	the primary key name(s) for this AR class.

save() public method

This method will call ActiveRecordInterface::insert when [[getIsNewRecord()|isNewRecord]] is true, or ActiveRecordInterface::update when [[getIsNewRecord()|isNewRecord]] is false. For example, to save a customer record: php $customer = new Customer; // or $customer = Customer::findOne($id); $customer->name = $name; $customer->email = $email; $customer->save();

public save ( boolean $runValidation = true, array $attributeNames = null ) : boolean
$runValidation	boolean	whether to perform validation (calling [[\yii\base\Model::validate()\|validate()]]) before saving the record. Defaults to `true`. If the validation fails, the record will not be saved to the database and this method will return `false`.
$attributeNames	array	list of attribute names that need to be saved. Defaults to `null`, meaning all attributes that are loaded from DB will be saved.
return	boolean	whether the saving succeeded (i.e. no validation errors occurred).

setAttribute() public method

Sets the named attribute value.

unlink() public method

The record with the foreign key of the relationship will be deleted if $delete is true. Otherwise, the foreign key will be set null and the record will be saved without validation.

public unlink ( string $name, static $model, boolean $delete = false )
$name	string	the case sensitive name of the relationship, e.g. `orders` for a relation defined via `getOrders()` method.
$model	static	the model to be unlinked from the current one.
$delete	boolean	whether to delete the model that contains the foreign key. If false, the model's foreign key will be set `null` and saved. If true, the model containing the foreign key will be deleted.

update() public method

Usage example: php $customer = Customer::findOne($id); $customer->name = $name; $customer->email = $email; $customer->update();

public update ( boolean $runValidation = true, array $attributeNames = null ) : integer \| boolean
$runValidation	boolean	whether to perform validation (calling [[\yii\base\Model::validate()\|validate()]]) before saving the record. Defaults to `true`. If the validation fails, the record will not be saved to the database and this method will return `false`.
$attributeNames	array	list of attributes that need to be saved. Defaults to `null`, meaning all attributes that are loaded from DB will be saved.
return	integer \| boolean	the number of rows affected, or `false` if validation fails or updating process is stopped for other reasons. Note that it is possible that the number of rows affected is 0, even though the update execution is successful.

updateAll() public static method

For example, to change the status to be 1 for all customers whose status is 2: php Customer::updateAll(['status' => 1], ['status' => '2']);

public static updateAll ( array $attributes, array $condition = null ) : integer
$attributes	array	attribute values (name-value pairs) to be saved for the record. Unlike [[update()]] these are not going to be validated.
$condition	array	the condition that matches the records that should get updated. Please refer to [[QueryInterface::where()]] on how to specify this parameter. An empty condition will match all records.
return	integer	the number of rows updated

public getAttribute ( string $name ) : mixed
$name	string	the attribute name
return	mixed	the attribute value. `null` if the attribute is not set or does not exist.

public setAttribute ( string $name, mixed $value )
$name	string	the attribute name.
$value	mixed	the attribute value.
