PHP Класс yii\grid\DataColumn

It is used to show data columns and allows [[enableSorting|sorting]] and [[filter|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 [[getDataCellValue|data cell value]] and the [[renderDataCellContent|data cell content]]. The cell value is an un-formatted value that may be used for calculation, while the actual cell content is a [[format|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.

Свойство Тип Описание
$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.
$enableSorting 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 whether the header label should be HTML-encoded.
$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; - 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.
$filterInputOptions 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.
$format in which format should the value of each data model be displayed as (e.g. "raw", "text", "html", ['date', 'php:Y-m-d']). Supported formats are determined by the [[GridView::formatter|formatter]] used by the GridView. Default format is "text" which will format the value as an HTML-encoded plain text when Formatter is used as the [[GridView::$formatter|formatter]] of the GridView.
$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 ActiveRecord, the label will be determined using [[\yii\db\ActiveRecord::getAttributeLabel()]]. Otherwise [[\yii\helpers\Inflector::camel2words()]] will be used to get a label.
$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.
$value an anonymous function or a string that is used to determine the value to display in the current column. If this is an anonymous function, it will be called for each row and the return value will be used as the value to display for every data model. The signature of this function should be: function ($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]].

$attribute публичное свойство

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 $attribute

$enableSorting публичное свойство

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.
public $enableSorting

public $encodeLabel

$filter публичное свойство

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; - 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 $filter

$filterInputOptions публичное свойство

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.
См. также: yii\helpers\Html::renderTagAttributes() for details on how attributes are being rendered.
public $filterInputOptions

$format публичное свойство

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 Formatter is used as the [[GridView::$formatter|formatter]] of the GridView.
public $format

$label публичное свойство

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.

Otherwise [[\yii\helpers\Inflector::camel2words()]] will be used to get a label.
