Inheritance	yii\widgets\DetailView » yii\base\Widget » yii\base\Component » yii\base\BaseObject
Implements	yii\base\Configurable, yii\base\ViewContextInterface
Available since version	2.0
Source Code	https://github.com/yiisoft/yii2/blob/master/framework/widgets/DetailView.php

DetailView displays the detail of a single data $model.

DetailView is best used for displaying a model in a regular format (e.g. each model attribute is displayed as a row in a table.) The model can be either an instance of yii\base\Model or an associative array.

DetailView uses the $attributes property to determines which model attributes should be displayed and how they should be formatted.

A typical usage of DetailView is as follows:

echo DetailView::widget([
    'model' => $model,
    'attributes' => [
        'title',               // title attribute (in plain text)
        'description:html',    // description attribute in HTML
        [                      // the owner name of the model
            'label' => 'Owner',
            'value' => $model->owner->name,
        ],
        'created_at:datetime', // creation date formatted as datetime
    ],
]);

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

Property Details

$attributes public property

A list of attributes to be displayed in the detail view. Each array element represents the specification for displaying one particular attribute.

An attribute can be specified as a string in the format of attribute, attribute:format or attribute:format:label, where attribute refers to the attribute name, and format represents the format of the attribute. The format is passed to the yii\i18n\Formatter::format() method to format an attribute value into a displayable text. Please refer to yii\i18n\Formatter for the supported types. Both format and label are optional. They will take default values if absent.

An attribute can also be specified in terms of an array with the following elements:

attribute: the attribute name. This is required if either label or value is not specified.
label: the label associated with the attribute. If this is not specified, it will be generated from the attribute name.
value: the value to be displayed. If this is not specified, it will be retrieved from $model using the attribute name by calling yii\helpers\ArrayHelper::getValue(). Note that this value will be formatted into a displayable text according to the format option. Since version 2.0.11 it can be defined as closure with the following parameters:
```
function ($model, $widget)
```
$model refers to displayed model and $widget is an instance of DetailView widget.
format: the type of the value that determines how the value would be formatted into a displayable text. Please refer to yii\i18n\Formatter for supported types and yii\i18n\Formatter::format() on how to specify this value.
visible: whether the attribute is visible. If set to false, the attribute will NOT be displayed.
contentOptions: the HTML attributes to customize value tag. For example: ['class' => 'bg-red']. Please refer to yii\helpers\BaseHtml::renderTagAttributes() for the supported syntax.
captionOptions: the HTML attributes to customize label tag. For example: ['class' => 'bg-red']. Please refer to yii\helpers\BaseHtml::renderTagAttributes() for the supported syntax.

public array $attributes = null

$formatter public property

The formatter used to format model attribute values into displayable texts. This can be either an instance of yii\i18n\Formatter or an configuration array for creating the yii\i18n\Formatter instance. If this property is not set, the formatter application component will be used.

public array|yii\i18n\Formatter $formatter = null

$model public property

The data model whose details are to be displayed. This can be a yii\base\Model instance, an associative array, an object that implements yii\base\Arrayable interface or simply an object with defined public accessible non-static properties.

public array|object $model = null

$options public property

The HTML attributes for the container tag of this widget. The tag option specifies what container tag should be used. It defaults to table if not set.

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

public array $options = ['class' => 'table table-striped table-bordered detail-view']

$template public property

The template used to render a single attribute. If a string, the token {label} and {value} will be replaced with the label and the value of the corresponding attribute. If a callback (e.g. an anonymous function), the signature must be as follows:

function ($attribute, $index, $widget)

where $attribute refer to the specification of the attribute being rendered, $index is the zero-based index of the attribute in the $attributes array, and $widget refers to this widget instance.

Since Version 2.0.10, the tokens {captionOptions} and {contentOptions} are available, which will represent HTML attributes of HTML container elements for the label and value.

public string|callable $template = '<tr><th{captionOptions}>{label}</th><td{contentOptions}>{value}</td></tr>'
