Method Details

getAllStatusListData() public static method

The array returned is suitable to be used as list data value in (for instance) a dropdown list control. Usage example : assuming model Post has a SimpleWorkflowBehavior the following code displays a dropdown list containing all statuses defined in $post current the workflow : 
echo Html::dropDownList(
		'status',
		null,
		WorkflowHelper::getAllStatusListData(
			$post->getWorkflow()->getId(),
			$post->getWorkflowSource()
		)
)
public static getAllStatusListData ( string $workflowId, IWorkflowSource $workflowSource ) : array
$workflowId string
$workflowSource IWorkflowSource
return array

getNextStatus() public static method

Returns the status string of the next valid status from the list of transitions
public static getNextStatus ( BaseActiveRecord | SimpleWorkflowBehavior $model ) : string
$model yii\db\BaseActiveRecord | raoul2000\workflow\base\SimpleWorkflowBehavior
return string

getNextStatusListData() public static method

Returns an associative array containing all statuses that can be reached by model.
public static getNextStatusListData ( BaseActiveRecord $model, boolean $validate = false, boolean $beforeEvents = false, boolean $includeCurrent = false ) : array
$model yii\db\BaseActiveRecord
$validate boolean when TRUE only those status with successfull attribute validation are included. When FALSE (default) Attribute validation is done performed.
$beforeEvents boolean when TRUE all configured *before* events are fired : only the status that don't invalidate the workflow event are included in the returned array, otherwise no event is fired and all next status are included
$includeCurrent boolean when TRUE the current model status is added to the returned array. When FALSE (default) only next statuses are included
return array

getStatusDropDownData() public static method

Example: 
$statusDropDownData = WorkflowHelper::getStatusDropDownData($model);
Html
echo Html::dropDownList('status', $model->status, $statusDropdown['items'], ['options' => $statusDropdown['options']]);
ActiveForm
echo $form->field($model, 'status')->dropDownList($statusDropDownData['items'], ['options' => $statusDropDownData['options']]);
public static getStatusDropDownData ( BaseActiveRecord | SimpleWorkflowBehavior $model ) : array
$model yii\db\BaseActiveRecord | raoul2000\workflow\base\SimpleWorkflowBehavior
return array

isValidNextStatus() public static method

Checks if a given status is a valid transition from the current status
public static isValidNextStatus ( BaseActiveRecord | SimpleWorkflowBehavior $model, string $status_id ) : boolean
$model yii\db\BaseActiveRecord | raoul2000\workflow\base\SimpleWorkflowBehavior
$status_id string
return boolean

renderLabel() public static method

This method assumes that the status includes a metadata value called 'labelTemplate' that contains the HTML template of the rendering status. In this template the string '{label}' will be replaced by the status label. Example : 
	'status' => [
		'draft' => [
			'label' => 'Draft',
			'transition' => ['ready' ],
			'metadata' => [
				'labelTemplate' => '{label}'
			]
		],
public static renderLabel ( BaseActiveRecord $model ) : string | null
$model yii\db\BaseActiveRecord
return string | null the HTML rendered status or null if not labelTemplate is found
