Class yii\grid\DataColumn

Inheritance yii\grid\DataColumn » yii\grid\Column » yii\base\Object
Implements yii\base\Configurable
Available since version 2.0
Source Code https://github.com/yiisoft/yii2/blob/master/framework/grid/DataColumn.php

DataColumn is the default column type for the yii\grid\GridView widget.

It is used to show data columns and allows sorting and filtering them.

A simple data column definition refers to an attribute in the data model of the GridView's data provider. The name of the attribute is specified by $attribute.

By setting $value and $label, the header and cell content can be customized.

A data column differentiates between the data cell value and the data cell content. The cell value is an un-formatted value that may be used for calculation, while the actual cell content is a formatted version of that value which may contain HTML markup.

For more details and usage information on DataColumn, see the guide article on data widgets.

Property Details

$attribute public property

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.

public string $attribute = null

$enableSorting public property

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

public boolean $enableSorting = true

$encodeLabel public property (available since version 2.0.1)

Whether the header label should be HTML-encoded.

See also $label.

public boolean $encodeLabel = true

$filter public property

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 yii\grid\GridView::$filterModel is set.

  • If this property is not set, a text field will be generated as the filter input;
  • 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.
public string|array|null|false $filter = null

$filterInputOptions public property

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.

See also yii\helpers\Html::renderTagAttributes() for details on how attributes are being rendered.

public array $filterInputOptions = ['class' => 'form-control', 'id' => null]

$format public property

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 formatter used by the yii\grid\GridView. Default format is "text" which will format the value as an HTML-encoded plain text when yii\i18n\Formatter is used as the formatter of the GridView.

public string|array $format = 'text'

$label public property

Label to be displayed in the 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.

public string $label = null

$sortLinkOptions public property

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

See also yii\helpers\Html::renderTagAttributes() for details on how attributes are being rendered.

public array $sortLinkOptions = []

$value public property

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 yii\grid\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.

public string|Closure $value = null

Method Details

getDataCellValue() public method

Returns the data cell value.

public string getDataCellValue ( $model, $key, $index )
$model mixed

The data model

$key mixed

The key associated with the data model

$index integer

The zero-based index of the data model among the models array returned by yii\grid\GridView::$dataProvider.

return string

The data cell value
