ViewPathRenderer extends BaseObject
in package
implements Renderer

A ViewPathRenderer is a simple Renderer implementation for rendering Viewables by searching for a matching viewFile relative to the Viewables class path or relative to a given $viewPath.

If a $viewPath is given the renderer will search for the view within this path directly.

If no $viewPath is given, the ViewPathRenderer will determine the view path relative to the Viewable as following:

  • In case $parent = false the renderer will search directly in the class path subdirectory views:

viewableClassPath/views

  • in case $parent = true the renderer will search in the parents views folder (e.g. in the modules main view folder):

viewableClassPath/../views

  • in case $subPath is given the subPath will be appended to the view path e.g:

For a subPath 'mail' and $parent = false the search path will be: viewableClassPath/views/mail

Properties

$parent

Can be used to search the parent's view folder (e.g. the modules base view folder) for the view file.

public bool $parent = false

Otherwise this renderer searches for a direct views subdirectory.

This field is ignored if $viewPath is given.

if set to true the renderer will search in the parents view directory for the view.

$subPath

public string $subPath

a subpath within the view folder used for searching the view e.g mails. This will only be used if $viewPath is not given.

Methods

__call()

Calls the named method which is not a class method.

public __call(string $name, array<string|int, mixed> $params) : mixed

Do not call this method directly as it is a PHP magic method that will be implicitly called when an unknown method is being invoked.

Parameters
$name : string

the method name

$params : array<string|int, mixed>

method parameters

Tags
throws
UnknownMethodException

when calling unknown method

Return values
mixed —

the method return value

__construct()

Constructor.

public __construct([array<string|int, mixed> $config = [] ]) : mixed

The default implementation does two things:

  • Initializes the object with the given configuration $config.
  • Call [[init()]].

If this method is overridden in a child class, it is recommended that

  • the last parameter of the constructor is a configuration array, like $config here.
  • call the parent implementation at the end of the constructor.
Parameters
$config : array<string|int, mixed> = []

name-value pairs that will be used to initialize the object properties

__get()

Returns the value of an object property.

public __get(string $name) : mixed

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $value = $object->property;.

Parameters
$name : string

the property name

Tags
throws
UnknownPropertyException

if the property is not defined

throws
InvalidCallException

if the property is write-only

see
__set()
Return values
mixed —

the property value

__isset()

Checks if a property is set, i.e. defined and not null.

public __isset(string $name) : bool

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing isset($object->property).

Note that if the property is not defined, false will be returned.

Parameters
$name : string

the property name or the event name

Tags
see
https://www.php.net/manual/en/function.isset.php
Return values
bool —

whether the named property is set (not null).

__set()

Sets value of an object property.

public __set(string $name, mixed $value) : mixed

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $object->property = $value;.

Parameters
$name : string

the property name or the event name

$value : mixed

the property value

Tags
throws
UnknownPropertyException

if the property is not defined

throws
InvalidCallException

if the property is read-only

see
__get()

__unset()

Sets an object property to null.

public __unset(string $name) : mixed

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing unset($object->property).

Note that if the property is not defined, this method will do nothing. If the property is read-only, it will throw an exception.

Parameters
$name : string

the property name

Tags
throws
InvalidCallException

if the property is read only.

see
https://www.php.net/manual/en/function.unset.php

canGetProperty()

Returns a value indicating whether a property can be read.

public canGetProperty(string $name[, bool $checkVars = true ]) : bool

A property is readable if:

  • the class has a getter method associated with the specified name (in this case, property name is case-insensitive);
  • the class has a member variable with the specified name (when $checkVars is true);
Parameters
$name : string

the property name

$checkVars : bool = true
