$attribute


    public
        string
    $attribute

the attribute name associated with this column. When neither [[content]] nor [[value]] is specified, the value of the specified attribute will be retrieved from each data model and displayed.

Also, if [[label]] is not specified, the label associated with the attribute will be displayed.

$content


    public
        callable
    $content

This is a callable that will be used to generate the content of each cell. The signature of the function should be the following: function ($model, $key, $index, $column). Where $model, $key, and $index refer to the model, key and index of the row currently being rendered and $column is a reference to the [[Column]] object.

$contentOptions


    public
        array<string|int, mixed>|Closure
    $contentOptions
     = []

the HTML attributes for the data cell tag. This can either be an array of attributes or an anonymous function ([[Closure]]) that returns such an array. The signature of the function should be the following: function ($model, $key, $index, $column). Where $model, $key, and $index refer to the model, key and index of the row currently being rendered and $column is a reference to the [[Column]] object. A function may be used to assign different attributes to different rows based on the data in that row.

$enableSorting


    public
        bool
    $enableSorting
     = true

whether to allow sorting by this column. If true and [[attribute]] is found in the sort definition of [[GridView::dataProvider]], then the header cell of this column will contain a link that may trigger the sorting when being clicked.

$encodeLabel


    public
        bool
    $encodeLabel
     = true

whether the header label should be HTML-encoded.

$filter


    public
        string|array<string|int, mixed>|null|false
    $filter

the HTML code representing a filter input (e.g. a text field, a dropdown list) that is used for this data column. This property is effective only when [[GridView::filterModel]] is set.

If this property is not set, a text field will be generated as the filter input with attributes defined with [[filterInputOptions]]. See [[\yii\helpers\BaseHtml::activeInput]] for details on how an active input tag is generated.
If this property is an array, a dropdown list will be generated that uses this property value as the list options.
If you don't want a filter for this data column, set this value to be false.

$filterAttribute


    public
        string|null
    $filterAttribute

the attribute name of the [[GridView::filterModel]] associated with this column. If not set, will have the same value as [[attribute]].

$filterInputOptions


    public
        array<string|int, mixed>
    $filterInputOptions
     = ['class' => 'form-control', 'id' => null]

the HTML attributes for the filter input fields. This property is used in combination with the [[filter]] property. When [[filter]] is not set or is an array, this property will be used to render the HTML attributes for the generated filter input fields.

Empty id in the default value ensures that id would not be obtained from the model attribute thus providing better performance.

$filterOptions


    public
        array<string|int, mixed>
    $filterOptions
     = []

the HTML attributes for the filter cell tag.

$footer


    public
        string
    $footer

the footer cell content. Note that it will not be HTML-encoded.

$footerOptions


    public
        array<string|int, mixed>
    $footerOptions
     = []

the HTML attributes for the footer cell tag.

$format


    public
        string|array<string|int, mixed>|Closure
    $format
     = 'text'

in which format should the value of each data model be displayed as (e.g. "raw", "text", "html", ['date', 'php:Y-m-d']). Supported formats are determined by the [[GridView::formatter|formatter]] used by the [[GridView]]. Default format is "text" which will format the value as an HTML-encoded plain text when [[\yii\i18n\Formatter]] is used as the [[GridView::$formatter|formatter]] of the GridView.

$grid


    public
        GridView
    $grid

the grid view object that owns this column.

$header


    public
        string|null
    $header

the header cell content. Note that it will not be HTML-encoded.

$headerOptions


    public
        array<string|int, mixed>
    $headerOptions
     = []

the HTML attributes for the header cell tag.

$label


    public
        string|null
    $label

label to be displayed in the [[header|header cell]] and also to be used as the sorting link label when sorting is enabled for this column. If it is not set and the models provided by the GridViews data provider are instances of [[\yii\db\ActiveRecord]], the label will be determined using [[\yii\db\ActiveRecord::getAttributeLabel()]]. Otherwise [[\yii\helpers\Inflector::camel2words()]] will be used to get a label.

$options


    public
        array<string|int, mixed>
    $options
     = []

the HTML attributes for the column group tag.

$sortLinkOptions


    public
        array<string|int, mixed>
    $sortLinkOptions
     = []

the HTML attributes for the link tag in the header cell generated by [[\yii\data\Sort::link]] when sorting is enabled for this column.

$userAttribute


    public
        string|null
    $userAttribute
     = null

name of user attribute

$value


    public
        string|Closure|null
    $value

an anonymous function or a string that is used to determine the value to display in the current column.

If this is an anonymous function, it will be called for each row and the return value will be used as the value to display for every data model. The signature of this function should be: function ($model, $key, $index, $column). Where $model, $key, and $index refer to the model, key and index of the row currently being rendered and $column is a reference to the [[DataColumn]] object.

You may also set this property to a string representing the attribute name to be displayed in this column. This can be used when the attribute to be displayed is different from the [[attribute]] that is used for sorting and filtering.

If this is not set, $model[$attribute] will be used to obtain the value, where $attribute is the value of [[attribute]].

$visible


    public
        bool
    $visible
     = true

whether this column is visible. Defaults to true.

__call()

Calls the named method which is not a class method.


    public
                    __call(string $name, array<string|int, mixed> $params) : mixed

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.

Parameters

$name : string: the method name
$params : array<string|int, mixed>: method parameters

Return values

mixed —

the method return value

__construct()

Constructor.


    public
                    __construct([array<string|int, mixed> $config = [] ]) : mixed

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 $config here.
call the parent implementation at the end of the constructor.

Parameters

$config : array<string|int, mixed> = []: name-value pairs that will be used to initialize the object properties

__get()

Returns the value of an object property.


    public
                    __get(string $name) : mixed

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $value = $object->property;.

Parameters

$name : string: the property name

Return values

mixed —

the property value

__isset()

Checks if a property is set, i.e. defined and not null.


    public
                    __isset(string $name) : bool

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.

Parameters

$name : string: the property name or the event name

Return values

bool —

whether the named property is set (not null).

__set()

Sets value of an object property.


    public
                    __set(string $name, mixed $value) : mixed

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $object->property = $value;.

Parameters

$name : string: the property name or the event name
$value : mixed: the property value

__unset()

Sets an object property to null.


    public
                    __unset(string $name) : mixed

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.

Parameters

$name : string: the property name

    public
                    canGetProperty(string $name[, bool $checkVars = true ]) : bool

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 $checkVars is true);

Parameters

$name : string: the property name
$checkVars : bool = true: whether to treat member variables as properties
