# Group action

# Api

# One level

If you need to do some operations with multiple rows, there are group actions. There are one or two level group actions. One level:

$grid->addGroupAction('Delete examples')->onSelect[] = [$this, 'deleteExamples'];
$grid->addGroupAction('Something alse')->onSelect[] = [$this, 'doSomethingElse'];
1
2

This will create one select box (['Delete examples', 'Something alse']) and submit button. If you submit that form, your handler will be called. It will be called via ajax.

This is how your handler can look like:

public function deleteExamples(array $ids): void
{
	// Your code...

	if ($this->isAjax()) {
		$this['groupActionsGrid']->reload();
	} else {
		$this->redirect('this');
	}
}

# Two level

There is also the two-level possibility of group action:

$grid->addGroupAction('Change order status', [
	1 => 'Received',
	2 => 'Ready',
	3 => 'Processing',
	4 => 'Sent',
	5 => 'Storno'
])->onSelect[] = [$this, 'groupChangeStatus'];

$grid->addGroupAction('Send', [
	'john'  => 'John',
	'joe'   => 'Joe',
	'frank' => 'Franta',
])->onSelect[] = [$this, 'groupSend'];

And some example handler:

public function groupChangeStatus(array $ids, $status): void
{
	$this->flashMessage(
		sprintf("Status of items with id: [%s] was changed to: [$status]", implode($ids, ',')),
		'success'
	);

	$this->exampleRepository->updateStatus($ids, $status);

	if ($this->isAjax()) {
		$this->redrawControl('flashes');
		$this['groupActionsGrid']->reload();
	} else {
		$this->redirect('this');
	}
}

# Text input

Group action can also containe a text input instad of select (As show in example above - option called "Add note"). Example code:

$grid->addGroupTextAction('Add note')
	->onSelect[] = [$this, 'addNote'];
1
2

And the ::addNote() method:

public function addNote(array $ids, $value): void
{
	$this->flashMessage(
		sprintf('Note [%s] was added to items with ID: [%s]', $value, implode($ids, ',')),
		'success'
	);

	if ($this->isAjax()) {
		$this->redrawControl('flashes');
		$this['groupActionsGrid']->reload();
	} else {
		$this->redirect('this');
	}

# Attributes, classes

All group action inputs have optional class or other attributes:

$grid->addGroupTextareaAction('aaaa')
	->setAttribute('rows', 10)
	->setClass('fooo');

# Happy inputs

DataGrid uses tiny library happy for those nice checkboxes. You can disable them:

$grid->useHappyComponents(false);
