Interfaces
- ActionInterface
- Interface for all action classes.
Properties
- $errors : array<string|int, mixed>
- $subaction : string
- $subactions : array<string|int, mixed>
- $obj : object
- $backcompat : array<string|int, mixed>
Methods
- call() : void
- Convenience method to load() and execute() an instance of this class.
- checkUsername() : mixed
- See if a username already exists.
- execute() : void
- Dispatcher to whichever sub-action method is necessary.
- exportStatic() : void
- Provides a way to export a class's public static properties and methods to global namespace.
- load() : object
- Static wrapper for constructor.
- register() : void
- Backward compatibility wrapper for show sub-action.
- show() : void
- Begin the registration process.
- __construct() : mixed
- Constructor. Protected to force instantiation via self::load().
Properties
$errors
public
array<string|int, mixed>
$errors
= []
Errors encountered while trying to register.
$subaction
public
string
$subaction
= 'show'
The sub-action to call.
$subactions
public
static array<string|int, mixed>
$subactions
= ['show' => 'show', 'usernamecheck' => 'checkUsername']
Available sub-actions.
$obj
protected
static object
$obj
An instance of this class. This is used by the load() method to prevent mulitple instantiations.
$backcompat
private
static array<string|int, mixed>
$backcompat
= ['func_names' => ['register' => 'Register']]
BackwardCompatibility settings for this class.
Methods
call()
Convenience method to load() and execute() an instance of this class.
public
static call() : void
checkUsername()
See if a username already exists.
public
checkUsername() : mixed
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:
- Use this trait in the class.
- 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.
load()
Static wrapper for constructor.
public
static load() : object
Return values
object —An instance of this class.
register()
Backward compatibility wrapper for show sub-action.
public
static register([array<string|int, mixed> $reg_errors = [] ]) : void
Parameters
- $reg_errors : array<string|int, mixed> = []
-
Holds information about any errors that occurred.
show()
Begin the registration process.
public
show() : void
__construct()
Constructor. Protected to force instantiation via self::load().
protected
__construct() : mixed
