NAME

Handel::Order - Module for maintaining order contents

SYNOPSIS

my $order = Handel::Order->new({
    id => '12345678-9098-7654-322-345678909876'
});

my $iterator = $order->items;
while (my $item = $iterator->next) {
    print $item->sku;
    print $item->price;
    print $item->total;
};

DESCRIPTION

Handel::Order is a component for maintaining simple order records.

While Handel::Order subclasses Class::DBI, it is strongly recommended that you not use its methods unless it's absolutely necessary. Stick to the documented methods here and you'll be safe should I decide to implement some other data access mechanism. :-)

CONSTRUCTOR

There are three ways to create a new order object. You can either pass a hashref into new containing all the required values needed to create a new order record or pass a hashref into load containing the search criteria to use to load an existing order or set of orders.

NOTE: The only required hash key is cart. new will copy the specified carts items inthe the order items. cart can be an already existing Handel::Cart object, of a hash reference of search critera, or a cart id (uuid).

When creating a new order from a cart, new will automatically create a new Handel::Checkout process and process CHECKOUT_PHASE_INITIALIZE on the new order. This can be disabled by passing any true value in the second option noprocess.

Handel::Order->new(\%data [, $noprocess])

my $order = Handel::Order->new({
    shopper => '10020400-E260-11CF-AE68-00AA004A34D5',
    id => '111111111-2222-3333-4444-555566667777',
    cart => $cartobject
});

my $order = Handel::Order->new({
    shopper => '10020400-E260-11CF-AE68-00AA004A34D5',
    id => '111111111-2222-3333-4444-555566667777',
    cart => '11112222-3333-4444-5555-666677778888'
});

my $order = Handel::Order->new({
    shopper => '10020400-E260-11CF-AE68-00AA004A34D5',
    id => '111111111-2222-3333-4444-555566667777',
    cart => {
        id => '11112222-3333-4444-5555-666677778888',
        type => CART_TYPE_TEMP
    }
});

Handel::Order->load([\%filter, $wantiterator])

my $order = Handel::Order->load({
    id => 'D597DEED-5B9F-11D1-8DD2-00AA004ABD5E'
});

You can also omit \%filter to load all available orders.

my @orders = Handel::Order->load();

In scalar context load returns a Handel::Order object if there is a single result, or a Handel::Iterator object if there are multiple results. You can force load to always return an iterator even if only one cart exists by setting the $wantiterator parameter to RETURNAS_ITERATOR.

my $iterator = Handel::Order->load(undef, RETURNAS_ITERATOR);
while (my $item = $iterator->next) {
    print $item->sku;
};

See Handel::Contstants for the available RETURNAS options.

A Handel::Exception::Argument exception is thrown if the first parameter is not a hashref.

METHODS

items([\%filter, [$wantiterator])

You can retrieve all or some of the items contained in the order via the items method. In a scalar context, items returns an iterator object which can be used to cycle through items one at a time. In list context, it will return an array containing all items.

my $iterator = $order->items;
while (my $item = $iterator->next) {
    print $item->sku;
};

my @items = $order->items;
...
dosomething(\@items);

When filtering the items in the order in scalar context, a Handel::Order::Item object will be returned if there is only one result. If there are multiple results, a Handel::Iterator object will be returned instead. You can force items to always return a Handel::Iterator object even if only one item exists by setting the $wantiterator parameter to RETURNAS_ITERATOR.

my $item = $order->items({sku => 'SKU1234'}, RETURNAS_ITERATOR);
if ($item->isa('Handel::Order::Item)) {
    print $item->sku;
} else {
    while ($item->next) {
        print $_->sku;
    };
};

See the RETURNAS constants in Handel::Constants for other options.

In list context, filtered items return an array of items just as when items is called without a filter specified.

my @items - $order->items((sku -> 'SKU1%'});

A Handel::Exception::Argument exception is thrown if parameter one isn't a hashref or undef.

count

Returns the number of items in the order object.

my $numitems = $order->count;
