How to use Shopping Cart in Laravel?

Add Item

You can pass a simple or a multidimensional array and to help you get started, we have listed below all the default indexes that you can pass when adding or updating a cart item.

File name : index.php

Add a single item

Cart::add([
'id' => 'tshirt',
'name' => 'T-Shirt',
'quantity' => 1,
'price' => 12.50,
]);

Add a single item with a custom index

Cart::add([
'id' => 'tshirt',
'name' => 'T-Shirt',
'quantity' => 1,
'price' => 12.50,
'sku' => 'tshirt-custom',
]);

Add a single item with attributes and a custom index

Cart::add([
'id' => 'tshirt',
'name' => 'T-Shirt',
'quantity' => 1,
'price' => 12.50,
'sku' => 'tshirt-red-large',
'attributes' => [

'color' => [
'label' => 'Red',
'value' => 'red',
],

'size' => [
'label' => 'Large',
'value' => 'l',
],

],
]);

Adding multiple items

Cart::add([

[
'id' => 'tshirt',
'name' => 'T-Shirt',
'quantity' => 1,
'price' => 12.50,
'sku' => 'tshirt-red-large',
'attributes' => [

'color' => [
'label' => 'Red',
'value' => 'red',
],

'size' => [
'label' => 'Large',
'value' => 'l',
],

],
],

[
'id' => 'sweatshirt',
'name' => 'Sweatshirt',
'quantity' => 1,
'price' => 98.32,
],

]);

'quantity' => 1,
'price' => 12.50,
]);

'63e2d7033fe95b9134a5737503d10ba5', ]);

Get all the items

$items = Cart::items();

foreach ($items as $item)
{
echo $item->price();
}

Check if an item exists

if (Cart::exists('c14c437bc9ae7d35a7c18ee151c6acc0'))
{
Cart::remove('c14c437bc9ae7d35a7c18ee151c6acc0');
}

Get a single item

$item = Cart::item('c14c437bc9ae7d35a7c18ee151c6acc0');

echo Cart::itemsSubtotal();

Cart::clear()

Cart::clear();

Cart::getIdentity()

Cart::getIdentity();

Cart::setIdentity()

Cart::setIdentity('my-new-cart-name');

Cart::sync()

This method is very useful when you want to synchronize a shopping cart that is stored on the database for example.

$items = [

[
'id' => 'tshirt',
'name' => 'T-Shirt',
'quantity' => 1,
'price' => 12.50,
],

[
'id' => 'sweatshirt',
'name' => 'Sweatshirt',
'quantity' => 1,
'price' => 98.32,
],

];

$collection = new Collection($items);

Cart::sync($collection);

Metadata

Managing metadata inside the cart like shipping or billing information is very easy.

Setting metadata is very easy, just provide an array with a key/value pair and you're done.

Cart::setMetaData() :-
$data = [
'full_name' => 'John Doe',
'address' => 'Example Street',
];

Cart::setMetaData('shipping_information', $data);

Cart::setMetaData('shipping_information.street', 'Street ABC');

Cart::getMetaData()

To return all the available metadata

$metadata = Cart::getMetaData();

To return metadata by keys

$metadata = Cart::getMetaData('shipping_information');
$metadata = Cart::getMetaData('shipping_information.full_name');

Cart::removeMetaData()

To remove all the metadata

Cart::removeMetaData();

To remove metadata by keys

Cart::removeMetaData('shipping_information.full_name');
Cart::removeMetaData('shipping_information');

Search

You can use one or multiple properties to search for items in the cart.

Find

Cart::find([

'id' => 'foobar',

]);

Cart::find([

'name' => 'Foo Bar',
'price' => 5,

]);

Cart::find([

'attributes' => [

'size' => [
'price' => 5,
],

],

]);

Attributes

Each item can have different attributes like size, color and you can even add a price to each attribute that will reflect on the final item price.

Cart::add([

'id' => 'tshirt',
'name' => 'T-Shirt',
'quantity' => 1,
'price' => 12.50,
'attributes' => [

'size' => [
'label' => 'Large',
'value' => 'l',
'price' => 5,
],

'color' => [
'label' => 'Red',
'value' => 'red',
],

],

]);

count()

The count() method counts the number of items in the collection.

$total = Cart::items()->count();

isEmpty()

The isEmpty() method can be used to check whether or not the collection has elements within it. It accepts no value and returns a boolean.

if ( ! Cart::items()->isEmpty())
{
echo 'We have items on our cart :)';
}
else
{
echo 'Cart is empty :(';
}
