class GridFieldDeleteAction extends AbstractGridFieldComponent implements GridField_ColumnProvider, GridField_ActionProvider, GridField_ActionMenuItem (View source)

This class is a {@link GridField} component that adds a delete action for objects.

This component also supports unlinking a relation instead of deleting the object.

Use the {@link $removeRelation} property set in the constructor.

$action = GridFieldDeleteAction::create(); // delete objects permanently

// removes the relation to object instead of deleting $action = GridFieldDeleteAction::create(true);

Details

static Injectable create(array ...$args)

An implementation of the factory method, allows you to create an instance of a class

This method will defer class substitution to the Injector API, which can be customised via the Config API to declare substitution classes.

This can be called in one of two ways - either calling via the class directly, or calling on Object and passing the class name as the first parameter. The following are equivalent: $list = DataList::create(SiteTree::class); $list = SiteTree::get();

Parameters

array ...$args

Return Value

Injectable

static Injectable singleton(string $class = null)

Creates a class instance by the "singleton" design pattern.

It will always return the same instance for this class, which can be used for performance reasons and as a simple way to access instance methods which don't rely on instance data (e.g. the custom SilverStripe static handling).

Parameters

string $class

Optional classname to create, if the called class should not be used

Return Value

Injectable

The singleton instance

__construct(bool $removeRelation = false)

Parameters

bool $removeRelation
  • true if removing the item from the list, but not deleting it

string getTitle(GridField $gridField, DataObject $record, $columnName)

Parameters

GridField $gridField
DataObject $record
$columnName

Return Value

string

$title

string|null getGroup(GridField $gridField, DataObject $record, $columnName)

Parameters

GridField $gridField
DataObject $record
$columnName

Return Value

string|null

$group

array getExtraData(GridField $gridField, DataObject $record, $columnName)

Parameters

GridField $gridField
DataObject $record
$columnName

Return Value

array

$data

augmentColumns(GridField $gridField, array $columns)

Add a column 'Delete'

Parameters

GridField $gridField
array $columns

List reference of all column names.

array getColumnAttributes(GridField $gridField, DataObject $record, string $columnName)

Return any special attributes that will be used for FormField::create_tag()

Parameters

string $columnName

Return Value

array

array getColumnMetadata(GridField $gridField, string $columnName)

Add the title

Parameters

GridField $gridField
string $columnName

Return Value

  • Map of arbitrary metadata identifiers to their values.

array getColumnsHandled(GridField $gridField)

Which columns are handled by this component

Parameters

  • HTML for the column. Return NULL to skip.

handleAction(GridField $gridField, string $actionName, array $arguments, array $data)

Handle the actions and apply any changes to the GridField

Parameters
