SerialColumn displays a column of row numbers (1-based).
To add a SerialColumn to the yii\grid\GridView, add it to the columns configuration as follows:
'columns' => [ // ... [ 'class' => 'yii\grid\SerialColumn', // you may configure additional properties here ], ] For more details and usage information on SerialColumn, see the guide article on data widgets.

Property Details
Method Details
Defined in: yii\base\BaseObject::__call()
Calls the named method which is not a class method.
Do not call this method directly as it is a PHP magic method that will be implicitly called when an unknown method is being invoked.
| public mixed __call ( string $name, array $params ) | ||
| $name | string | The method name |
| $params | array | Method parameters |
| return | mixed | The method return value |
|---|---|---|
| throws | yii\base\UnknownMethodException | when calling unknown method |
public function __call($name, $params) { throw new UnknownMethodException('Calling unknown method: ' . get_class($this) . "::$name()"); } Defined in: yii\base\BaseObject::__construct()
Constructor.
The default implementation does two things:
- Initializes the object with the given configuration
$config. - Call init().
If this method is overridden in a child class, it is recommended that
- the last parameter of the constructor is a configuration array, like
$confighere. - call the parent implementation at the end of the constructor.
| public mixed __construct ( array $config = [] ) | ||
| $config | array | Name-value pairs that will be used to initialize the object properties |
public function __construct($config = []) { if (!empty($config)) { Yii::configure($this, $config); } $this->init(); } Defined in: yii\base\BaseObject::__get()
Returns the value of an object property.
Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $value = $object->property;.
See also __set().
| public mixed __get ( string $name ) | ||
| $name | string | The property name |
| return | mixed | The property value |
|---|---|---|
| throws | yii\base\UnknownPropertyException | if the property is not defined |
| throws | yii\base\InvalidCallException | if the property is write-only |
public function __get($name) { $getter = 'get' . $name; if (method_exists($this, $getter)) { return $this->$getter(); } elseif (method_exists($this, 'set' . $name)) { throw new InvalidCallException('Getting write-only property: ' . get_class($this) . '::' . $name); } throw new UnknownPropertyException('Getting unknown property: ' . get_class($this) . '::' . $name); } Defined in: yii\base\BaseObject::__isset()
Checks if a property is set, i.e. defined and not null.
Do not call this method directly as it is a PHP magic method that will be implicitly called when executing isset($object->property).
Note that if the property is not defined, false will be returned.
| public boolean __isset ( string $name ) | ||
| $name | string | The property name or the event name |
| return | boolean | Whether the named property is set (not null). |
|---|---|---|
public function __isset($name) { $getter = 'get' . $name; if (method_exists($this, $getter)) { return $this->$getter() !== null; } return false; } Defined in: yii\base\BaseObject::__set()
Sets value of an object property.
Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $object->property = $value;.
See also __get().
| public mixed __set ( string $name, mixed $value ) | ||
| $name | string | The property name or the event name |
| $value | mixed | The property value |
| throws | yii\base\UnknownPropertyException | if the property is not defined |
|---|---|---|
| throws | yii\base\InvalidCallException | if the property is read-only |
public function __set($name, $value) { $setter = 'set' . $name; if (method_exists($this, $setter)) { $this->$setter($value); } elseif (method_exists($this, 'get' . $name)) { throw new InvalidCallException('Setting read-only property: ' . get_class($this) . '::' . $name); } else { throw new UnknownPropertyException('Setting unknown property: ' . get_class($this) . '::' . $name); } } Defined in: yii\base\BaseObject::__unset()
Sets an object property to null.
Do not call this method directly as it is a PHP magic method that will be implicitly called when executing unset($object->property).
Note that if the property is not defined, this method will do nothing. If the property is read-only, it will throw an exception.
| public mixed __unset ( string $name ) | ||
| $name | string | The property name |
| throws | yii\base\InvalidCallException | if the property is read only. |
|---|---|---|
public function __unset($name) { $setter = 'set' . $name; if (method_exists($this, $setter)) { $this->$setter(null); } elseif (method_exists($this, 'get' . $name)) { throw new InvalidCallException('Unsetting read-only property: ' . get_class($this) . '::' . $name); } } Defined in: yii\base\BaseObject::canGetProperty()
Returns a value indicating whether a property can be read.
A property is readable if:
- the class has a getter method associated with the specified name (in this case, property name is case-insensitive);
- the class has a member variable with the specified name (when
$checkVarsis true);
See also canSetProperty().
| public boolean canGetProperty ( string $name, boolean $checkVars = true ) | ||
| $name | string | The property name |

Returns a value indicating whether a property can be set.
A property is writable if:
- the class has a setter method associated with the specified name (in this case, property name is case-insensitive);
- the class has a member variable with the specified name (when
$checkVarsis true);
See also canGetProperty().
| public boolean canSetProperty ( string $name, boolean $checkVars = true ) | ||
| $name | string | The property name |
| $checkVars | boolean | Whether to treat member variables as properties |
| return | boolean | Whether the property can be written |
|---|---|---|

Returns the fully qualified name of this class.
| public static string className ( ) | ||
| return | string | The fully qualified name of this class. |

| return | string | Label |
|---|---|---|
protected function getHeaderCellLabel() { return $this->grid->emptyCell; } Defined in: yii\base\BaseObject::hasMethod()

| return | boolean | Whether the method is defined |
|---|---|---|
public function hasMethod($name) { return method_exists($this, $name); } Defined in: yii\base\BaseObject::hasProperty()

$checkVarsis true);
See also:
| public boolean hasProperty ( string $name, boolean $checkVars = true ) | ||
