gravityflow_step_schedule_timestamp

Parameters

Parameter Type Definition
$schedule_timestamp integer The current scheduled timestamp (UTC)
$schedule_type string The type of schedule defined in step settings.
$step Gravity_Flow_Step The current step.
Example 1 - Adjust delay based on a field value 
add_filter( 'gravityflow_step_schedule_timestamp', 'schedule_business_hours', 10, 3 );
function schedule_business_hours( $schedule_timestamp, $schedule_type, $step ) {
	//Ensure you are only adjusting the desired form/step
	if ( $step->get_id() !== 76 ) {
		return $schedule_timestamp;
	}
	$entry = $step->get_entry();
	if ( $entry && isset( $entry['2'] ) && $entry['2'] == 'No Service Level Agreement' ) {
		$schedule_timestamp = strtotime('+1 day', $schedule_timestamp );
	}
        return $schedule_timestamp;
}
Example 2 - Delay based on business hours
Scheduling a step gives you many options for how to delay the start of a step. This filter supports additional cases where more complex logic is needed to determine when the step should start - aka the length of the delay. 
The example below covers a use case of delaying notifications for a particular step to only occur during business hours. After accounting for your timezone (as defined in WordPress settings), it compares the default scheduled timestamp of 5 minutes to a Monday-to-Friday, 9 to 5 business day. If appropriate, it will delay the notification to the next business day.
  • Create a notification step
    Specify a schedule delay of 5 minutes. This will be the default that applies to steps that are attempted during business hours.
    Take note of the Step ID.

Add the snippet
  • Include it in your theme functions.php file or a site plugin and update the values in lines 4 to 9 to match your scenario:
    - Line 4 - The Step ID (76 in example)
    - Line 8 - The $start_hour variable (24-hour time-zone matched)
    - Line 9 - The $end_hour variable (24-hour time-zone matched)

Note: The snippet above does not take into consideration minutes, only the hours and day such that:

  • If the workflow step was requested at 11:43PM on a Tuesday,
    It would be scheduled to send out at 9:43AM Wednesday.
  • If the workflow step was requested at 6:12AM on a Saturday,
    It would be scheduled to send out at 9:12AM Monday.
