Constants

EXPOSE_CLASSNAME_FULLY_QUALIFIED

Definition for the class name exposure configuration, that is, if the class name of an object should also be part of the output JSON, if configured.

public mixed EXPOSE_CLASSNAME_FULLY_QUALIFIED = 1

Setting this value, the object's class name is fully put out, including the namespace.

EXPOSE_CLASSNAME_UNQUALIFIED

Puts out only the actual class name without namespace.

public mixed EXPOSE_CLASSNAME_UNQUALIFIED = 2

See EXPOSE_CLASSNAME_FULL for the meaning of the constant at all.

Properties

$configuration

The rendering configuration for this JSON view which determines which properties of each variable to render.

protected array<string|int, mixed> $configuration = []

The configuration array must have the following structure:

Example 1:

[ 'variable1' => [ '_only' => ['property1', 'property2', ...] ], 'variable2' => [ '_exclude' => ['property3', 'property4, ...] ], 'variable3' => [ '_exclude' => ['secretTitle'], '_descend' => [ 'customer' => [ '_only' => ['firstName', 'lastName'] ] ] ], 'somearrayvalue' => [ '_descendAll' => [ '_only' => ['property1'] ] ] ]

Of variable1 only property1 and property2 will be included. Of variable2 all properties except property3 and property4 are used. Of variable3 all properties except secretTitle are included.

If a property value is an array or object, it is not included by default. If, however, such a property is listed in a "_descend" section, the renderer will descend into this sub structure and include all its properties (of the next level).

The configuration of each property in "_descend" has the same syntax like at the top level. Therefore - theoretically - infinitely nested structures can be configured.

To export indexed arrays the "_descendAll" section can be used to include all array keys for the output. The configuration inside a "_descendAll" will be applied to each array element.

Example 2: exposing object identifier

[ 'variableFoo' => [ '_exclude' => ['secretTitle'], '_descend' => [ 'customer' => [ // consider 'customer' being a persisted entity '_only' => ['firstName'], '_exposeObjectIdentifier' => TRUE, '_exposedObjectIdentifierKey' => 'guid' ] ] ] ]

Note for entity objects you are able to expose the object's identifier also, just add an "_exposeObjectIdentifier" directive set to TRUE and an additional property '__identity' will appear keeping the persistence identifier. Renaming that property name instead of '__identity' is also possible with the directive "_exposedObjectIdentifierKey". Example 2 above would output (summarized): {"customer":{"firstName":"John","guid":"892693e4-b570-46fe-af71-1ad32918fb64"}}

Example 3: exposing object's class name

[ 'variableFoo' => [ '_exclude' => ['secretTitle'], '_descend' => [ 'customer' => [ // consider 'customer' being an object '_only' => ['firstName'], '_exposeClassName' => \TYPO3\CMS\Extbase\Mvc\View\JsonView::EXPOSE_CLASSNAME_FULLY_QUALIFIED ] ] ] ]

The _exposeClassName is similar to the objectIdentifier one, but the class name is added to the JSON object output, for example (summarized): {"customer":{"firstName":"John","__class":"Acme\Foo\Domain\Model\Customer"}}

The other option is EXPOSE_CLASSNAME_UNQUALIFIED which only will give the last part of the class without the namespace, for example (summarized): {"customer":{"firstName":"John","__class":"Customer"}} This might be of interest to not provide information about the package or domain structure behind.

$currentVariable

protected string $currentVariable = ''

$variables

View variables and their values

assign()

$variablesToRender

Only variables whose name is contained in this array will be rendered

protected array<string|int, string> $variablesToRender = ['value']

Methods

assign()

Add a variable to $this->viewData.

public assign(string $key, mixed $value) : self

Can be chained, so $this->view->assign(..., ...)->assign(..., ...); is possible

Parameters
$key : string

Key of variable

$value : mixed

Value of object

Return values
self —

an instance of $this, to enable chaining

assignMultiple()

Add multiple variables to $this->viewData.

public assignMultiple(array<string|int, mixed> $values) : self
Parameters
$values : array<string|int, mixed>

array in the format array(key1 => value1, key2 => value2).

Return values
self —

an instance of $this, to enable chaining

render()

Transforms the value view variable to a serializable array representation using a YAML view configuration and JSON encodes the result.

public render() : string
Return values
string —

The JSON encoded variables

renderPartial()

Parameters
$partialName : mixed
$sectionName : mixed

renderSection()

public renderSection(mixed $sectionName[, array<string|int, mixed> $variables = [] ][, mixed $ignoreUnknown = false ]) : mixed
Parameters

Object to traverse

$configuration : array<string|int, mixed>

Configuration for transforming the given object or NULL

Return values
array<string|int, mixed>|string —

Object structure as an array or as a rendered string (for a DateTime instance)

transformValue()

Transforms a value depending on type recursively using the supplied configuration.

protected transformValue(mixed $value, array<string|int, mixed> $configuration[, bool $firstLevel = false ]) : mixed
Parameters
$value : mixed

The value to transform

$configuration : array<string|int, mixed>
