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
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 eitherlabel
orvalue
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 $model using the attribute name by calling yii\helpers\ArrayHelper::getValue(). Note that this value will be formatted into a displayable text according to theformat
option. Since version 2.0.11 it can be defined as closure with the following parameters:function ($model, $widget)
$model
refers to displayed model and$widget
is an instance ofDetailView
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 tofalse
, 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.
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.
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.
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.
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.
