getChildren Delegate Class Method

Return to Delegate class methods

The getChildren() method can be implemented in a table’s delegate class to specify the logical “child” records of a given record which can be used when creating hierarchical applications. This method will effectively override the output of the Dataface_Record::getChildren() method for records of this table.

Signature 

function getChildren( Dataface_Record $record) : Dataface_Record[]

Parameters

  1. $record - The Dataface_Record that is the subject of the query

Returns

This method should return an array of Dataface_Record objects that are considered to be children of the subject record.

Examples 

function getChildren($record){
    return df_get_records('webpages', 
        array(
            'parent_id'=>'='.$record->val('webpage_id')
        )
    );
}
