AmazonSubscription extends AmazonSubscriptionCore
in package

Creates a subscription on Amazon or updates it, or registers subscription destinations.

This Amazon Subscriptions Core object creates or updates subscriptions and subscription destinations on Amazon for a particular marketplace. In order to do any of these actions, a marketplace ID is needed in addition to a destination's delivery channel and list of attributes. The current store's configured marketplace is used by default. In order to fetch or delete a subscription, a notification type is also needed. In order to create a subscription, an indicator of whether or not the subscription is enabled is required in addition to a notification type.

setMock()

Enables or disables Mock Mode for the object.

public setMock([bool $b = true ][, array<string|int, mixed>|string|int $files = null ]) : mixed

Use this method when you want to test your object without sending actual requests to Amazon. When Mock Mode is enabled, responses are pulled from files you specify instead of sending the request. Be careful, as this means that the parameters you send will not necessarily match the response you get back. The files are pulled in order of the list, looping back to the first file after the last file is used. The log records every time a file is set or used, or if the file is missing. This method is also used to set response codes used by certain functions. Mock Mode is particularly useful when you need to test functions such as canceling orders or adding new products.

Parameters
$b : bool = true

[optional]

When set to TRUE, Mock Mode is enabled for the object. Defaults to TRUE.

$files : array<string|int, mixed>|string|int = null

[optional]

The list of files (or single file) to be used with Mock Mode. If a single string is given, this method will put it into an array. Integers can also be given, for use in fetchMockResponse. These numbers should only be response codes, such as 200 or 404.

Return values
mixed

setNotificationType()

Sets the notification type. (Required for subscriptions)

public setNotificationType(string $s) : bool

This parameter is required for performing any actions with subscriptions.

Parameters
$s : string

See the comment inside for a list of valid values.

Return values
bool

FALSE if improper input

setStore()

Sets the store values.

public setStore(string $s) : mixed

This method sets a number of key values from the config file. These values include your Merchant ID, Access Key ID, and Secret Key, and are critical for making requests with Amazon. If the store cannot be found in the config file, or if any of the key values are missing, the incident will be logged.

Parameters

This constructor is called when initializing all objects in this library. The parameters are passed by the child objects' constructors.

Parameters

Name for the store you want to use as seen in the config file. If this is not set to a valid name, none of these objects will work.

$mock : bool = false

[optional]

This is a flag for enabling Mock Mode. When this is set to TRUE, the object will fetch responses from files you specify instead of sending the requests to Amazon. The log will indicate whether mock mode is on or off each time an object is initialized. This defaults to FALSE.

$m : array<string|int, mixed>|string = null

[optional]

The files (or file) to use in Mock Mode. When Mock Mode is enabled, the object will retrieve one of these files from the list to use as a response. See setMock for more information.

checkResponse()

Checks whether or not the response is OK.

fetchMockFile()

Fetches the given mock file, or attempts to.

protected fetchMockFile([bool $load = true ]) : SimpleXMLObject|string|bool

This method is only called when Mock Mode is enabled. This is where files from the mock file list are retrieved and passed back to the caller. The success or failure of the operation will be recorded in the log, including the name and path of the file involved. For retrieving response codes, see fetchMockResponse.

Parameters
$load : bool = true

[optional]

Set this to FALSE to prevent the method from loading the file's contents into a SimpleXMLObject. This is for when the contents of the file are not in XML format, or if you simply want to retrieve the raw string of the file.

Return values
SimpleXMLObject|string|bool

A SimpleXMLObject holding the contents of the file, or a string of said contents if $load is set to FALSE. The return will be FALSE if the file cannot be fetched for any reason.

fetchMockResponse()

Generates a fake HTTP response using the mock file list.

protected fetchMockResponse() : bool|array<string|int, mixed>

This method uses the response codes in the mock file list to generate an HTTP response. The success or failure of this operation will be recorded in the log, including the response code returned. This is only used by a few operations. The response array will contain the following fields:

  • head - ignored, but set for the sake of completion
  • body - empty XML, also ignored
  • code - the response code fetched from the list
  • answer - answer message
  • error - error message, same value as answer, not set if status is 200
  • ok - 1 or 0, depending on if the status is 200
Return values
bool|array<string|int, mixed>

An array containing the HTTP response, or simply the value FALSE if the response could not be found or does not match the list of valid responses.

string

query string to send to cURL

genTime()

Generates timestamp in ISO8601 format.

protected genTime([string $time = false ]) : string

This method creates a timestamp from the provided string in ISO8601 format. The string given is passed through strtotime before being used. The value returned is actually 30 seconds early, to prevent it from tripping up Amazon. If no time is given, the current time is used.

Parameters
$time : string = false

[optional]

The time to use. Since this value is passed through strtotime first, values such as "-1 hour" are fine. Defaults to the current time.

Return values
string

Unix timestamp of the time, minus 30 seconds.

log()
