Multiple Option List lets the visitor tick several choices. The value is an array of the ticked options’ values.

Key settings

Options are configured exactly like the Option List. It can render as a set of check-boxes or a multi-select box.

In code

$total = 0;
$prices = ['war' => 40, 'ins' => 60, 'trn' => 90];
foreach ((array) $extras as $code) {
    $total += $prices[$code] ?? 0;
}

To print it, join it first: $list = implode(', ', (array) $extras);.
