Properties

$sort_default

public string $sort_default = 'last_post'

Default sort method. Must be a key in $this->sort_methods.

$sort_methods

public array<string|int, mixed> $sort_methods = ['subject' => ['column' => 'mf.subject', 'joins' => 'JOIN {db_prefix}messages AS mf ON (mf.id_msg = t.id_first_msg)', 'asc_default' => true], 'starter' => ['column' => 'COALESCE(memf.real_name, mf.poster_name)', 'joins' => 'JOIN {db_prefix}messages AS mf ON (mf.id_msg = t.id_first_msg)' . "\n\t\t\t" . 'LEFT JOIN {db_prefix}members AS memf ON (memf.id_member = mf.id_member)', 'asc_default' => true], 'last_poster' => ['column' => 'COALESCE(meml.real_name, ml.poster_name)', 'joins' => 'JOIN {db_prefix}messages AS ml ON (ml.id_msg = t.id_last_msg)' . "\n\t\t\t" . 'LEFT JOIN {db_prefix}members AS meml ON (meml.id_member = ml.id_member)', 'asc_default' => true], 'replies' => ['column' => 't.num_replies', 'joins' => '', 'asc_default' => true], 'views' => ['column' => 't.num_views', 'joins' => '', 'asc_default' => true], 'first_post' => ['column' => 't.id_topic', 'joins' => '', 'asc_default' => false], 'last_post' => ['column' => 't.id_last_msg', 'joins' => '', 'asc_default' => false]]

Default sort methods.

$ascending

protected bool $ascending

Whether to sort in ascending order or not.

$ascending_is_default

protected bool $ascending_is_default = false

Whether the $ascending value is the default for this sort method. Assume false until proven otherwise.

$obj

protected static object $obj

An instance of this class.

$sort_by

protected string $sort_by

Selected sort method.

$sort_column

protected string $sort_column

Selected sort column.

$backcompat

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

BackwardCompatibility settings for this class.

Methods

buildTopicContext()

Processes information about topics.

public static buildTopicContext(array<string|int, mixed> $row) : mixed

Populates Utils:$context['topics'] with the results.

This is static so that it can be called by SMF\Actions\Unread, etc.

Parameters
$row : array<string|int, mixed>

call()

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

public static call() : void

execute()

Shows the list of topics in this board, along with any child boards.

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.

getBoardList()

Buils and returns the list of available boards for a user.

public static getBoardList([array<string|int, mixed> $boardListOptions = [] ]) : array<string|int, mixed>
Parameters
$boardListOptions : array<string|int, mixed> = []

An array of options for the board list.

Return values
array<string|int, mixed>

An array of board info.

load()

Static wrapper for constructor.

public static load() : object
Return values
object

An instance of this class.
