Class yii\grid\DataColumn

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.

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.

Whether the header label should be HTML-encoded.

See also $label.

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 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.

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.

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

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.

See also yii\i18n\Formatter::format().

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.

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.

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.
