class GridFieldSortableHeader extends AbstractGridFieldComponent implements GridField_HTMLProvider, GridField_DataManipulator, GridField_ActionProvider, GridField_StateProvider (View source)

GridFieldSortableHeader adds column headers to a GridField that can also sort the columns.

Methods

public static 
create(mixed ...$args)

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

public static 
singleton(string $class = null)

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

public
$this
setThrowExceptionOnBadDataType(bool $throwExceptionOnBadDataType) deprecated

Determine what happens when this component is used with a list that isn't SS_Filterable.

public

protected
bool
checkDataType(SS_List $dataList)

Check that this dataList is of the right data type.

public
$this
setFieldSorting(array $sorting)

Specify sorting with fieldname as the key, and actual fieldname to sort as value.

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

Handle an action on the given GridField.

public
getManipulatedData(GridField $gridField, SS_List $dataList)

Returns the manipulated (sorted) DataList. Field names will simply add an 'ORDER BY' clause, relation names will add appropriate joins to the DataQuery first.

Details

static Injectable create(mixed ...$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

mixed ...$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

$this setThrowExceptionOnBadDataType(bool $throwExceptionOnBadDataType) deprecated

deprecated 5.2.0 Will be removed without equivalent functionality

Determine what happens when this component is used with a list that isn't SS_Filterable.

  • true: An exception is thrown
    • false: This component will be ignored - it won't make any changes to the GridField.

By default, this is set to true so that it's clearer what's happening, but the predefined GridFieldConfig subclasses set this to false for flexibility.

Parameters

bool $throwExceptionOnBadDataType

Return Value

$this

bool getThrowExceptionOnBadDataType() deprecated

deprecated 5.2.0 Will be removed without equivalent functionality

See setThrowExceptionOnBadDataType()

Return Value

bool

protected bool checkDataType(SS_List $dataList)

Check that this dataList is of the right data type.

Returns false if it's a bad data type, and if appropriate, throws an exception.

Parameters

SS_List $dataList

Return Value

bool

$this setFieldSorting(array $sorting)

Specify sorting with fieldname as the key, and actual fieldname to sort as value.

Example: array("MyCustomTitle"=>"Title", "MyCustomBooleanField" => "ActualBooleanField")

Parameters

array $sorting

Return Value

$this

array getFieldSorting()

No description

Return Value

array

array getHTMLFragments(GridField $gridField)

Returns the header row providing titles with sort buttons

Parameters

GridField $gridField

Return Value

array

array getActions(GridField $gridField)

No description

Parameters

GridField $gridField

Return Value

array

with action identifier strings.

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

Handle an action on the given GridField.

Calls ALL components for every action handled, so the component needs to ensure it only accepts actions it is actually supposed to handle.

Parameters

GridField $gridField
string $actionName

Action identifier, see getActions().

array $arguments

Arguments relevant for this

array $data

All form data

SS_List getManipulatedData(GridField $gridField, SS_List $dataList)

Returns the manipulated (sorted) DataList. Field names will simply add an 'ORDER BY' clause, relation names will add appropriate joins to the DataQuery first.

Parameters

GridField $gridField
SS_List $dataList

Return Value

SS_List

void initDefaultState(GridState_Data $data)

Initialise the default state in the given GridState_Data

We recommend that you call $data->initDefaults() to do this.

Parameters

GridState_Data $data

The top-level state object

Return Value

void
