Properties

$type

public string $type = 'topic'

The notification type that this action handles.

$alert_pref

protected int $alert_pref

Preference value to save to the table.

$id

protected int $id

ID of the topic or board.

$member_info

protected array<string|int, mixed> $member_info

Information about the user whose notifications preferences are changing. Will include ID number and email address.

$mode

protected int $mode

Requested notification mode.

$obj

protected static object $obj

An instance of this class. This is used by the load() method to prevent mulitple instantiations.

$token

protected string $token

The unsubscribe token that the user supplied, if any.

$backcompat

private static array<string|int, mixed> $backcompat = ['func_names' => ['call' => 'TopicNotify']]

BackwardCompatibility settings for this class.

Methods

call()

Convenience method to load() and execute() an instance of this class.

public static call() : void

createUnsubscribeToken()

Builds an unsubscribe token.

public static createUnsubscribeToken(int $memID, string $email[, string $type = '' ][, int $itemID = 0 ]) : string
Parameters
$memID : int

The id of the member that this token is for

$email : string

The member's email address

$type : string = ''

The type of notification the token is for (e.g. 'board', 'topic', etc.)

$itemID : int = 0

The id of the notification item, if applicable.

Return values
string —

The unsubscribe token

deleteNotifyPrefs()

Deletes notification preference.

public static deleteNotifyPrefs(int $memID, array<string|int, mixed> $prefs) : mixed
Parameters
$memID : int

The user whose preference you're setting

$prefs : array<string|int, mixed>

The preferences to delete

execute()

Dispatcher to whichever sub-action method is necessary.

public execute() : void

exportStatic()

Provides a way to export a class's public static properties and methods to global namespace.

public static exportStatic() : void

To do so:

  1. Use this trait in the class.
  2. At the END of the class's file, call its exportStatic() method.

Although it might not seem that way at first glance, this approach conforms to section 2.3 of PSR 1, since executing this method is simply a dynamic means of declaring functions when the file is included; it has no other side effects.

Regarding the $backcompat items:

A class's static properties are not exported to global variables unless explicitly included in $backcompat['prop_names']. Likewise, a class's static methods are not exported as global functions unless explicitly included in $backcompat['func_names'].

$backcompat['prop_names'] is a simple array where the keys are the names of one or more of a class's static properties, and the values are the names of global variables. In each case, the global variable will be set to a reference to the static property. Static properties that are not named in this array will not be exported.

$backcompat['func_names'] is a simple array where the keys are the names of one or more of a class's static methods, and the values are the names that should be used for global functions that will encapsulate those methods. Methods that are not named in this array will not be exported.

Adding non-static properties or methods to the $backcompat arrays will produce runtime errors. It is the responsibility of the developer to make sure not to do this.

getMemberWithToken()

Verifies a member's unsubscribe token, then returns some member info.

public static getMemberWithToken(string $type) : array<string|int, mixed>

Return values
array<string|int, mixed> —

The id and email address of the specified member

getNotifyPrefs()

public static getNotifyPrefs(int|array<string|int, mixed> $members[, string|array<string|int, mixed> $prefs = '' ][, bool $process_default = false ]) : array<string|int, mixed>

$prefs : string|array<string|int, mixed> = ''

An empty string to load all preferences, or a string (or array) of preference name(s) to load

$process_default : bool = false
