When updating a blank repeater field you’ll receive a PHP Fatal error: [] operator not supported for strings

To get around this –

$field_key = "field_123456789";
$post_id = "user_" . $user_id;

if ( get_field($field_key, $post_id) ){
	$value = get_field($field_key, $post_id);
} else {
	$value = array();
}

$value[] = array("hours" => $enrolled_class, "date" => $stripe_date);
	
update_field( $field_key, $value, $post_id );
