$helpers : array
Helpers used by RSS Helper
RSS Helper class for easy output RSS structures.
Provides common methods and features.
Helpers support a number of callback methods. These callbacks allow you to hook into the various view lifecycle events and either modify existing view content or perform other application specific logic. The events are not implemented by this base class, as implementing a callback method subscribes a helper to the related event. The callback methods are as follows:
beforeRender(Event $event, $viewFile) - beforeRender is called before the view file is rendered.afterRender(Event $event, $viewFile) - afterRender is called after the view file is rendered
but before the layout has been rendered.afterLayout(Event $event, $layoutFile) - afterLayout is called after the layout has rendered.beforeRenderFile(Event $event, $viewFile) - Called before any view fragment is rendered.afterRenderFile(Event $event, $viewFile, $content) - Called after any view fragment is rendered.
If a listener returns a non-null value, the output of the rendered file will be set to that.$_View : \Cake\View\View
The View instance this helper is attached to
__construct(\Cake\View\View $view, array $settings = array())
Default Constructor
| \Cake\View\View | $view | |
| array | $settings |
__get(string $name) : \Cake\View\Helper|null
Lazy loads helpers.
| string | $name | Name of the property being accessed. |
Helper instance if helper with provided name exists
getView() : \Cake\View\View
Get the view instance this helper is bound to.
The bound view instance.
addClass(array $options = array(), string|null $class = null, string $key = 'class') : array
Adds the given class to the element options
| array | $options | Array options/attributes to add a class to |
| string|null | $class | The class name being added. |
| string | $key | the key to use for class. |
Array of options with $key set.
implementedEvents() : array
Event listeners.
By defining one of the callback methods a helper is assumed to be interested in the related event.
Override this method if you need to add non-conventional event listeners. Or if you want helpers to listen to non-standard events.
setConfig(string|array $key, mixed|null $value = null, boolean $merge = true) : $this
Sets the config.
Setting a specific value:
$this->setConfig('key', $value);Setting a nested value:
$this->setConfig('some.nested.key', $value);Updating multiple config settings at the same time:
$this->setConfig(['one' => 'value', 'another' => 'value']);| string|array | $key | The key to set, or a complete array of configs. |
| mixed|null | $value | The value to set. |
| boolean | $merge | Whether to recursively merge or overwrite existing config, defaults to true. |
When trying to set a key that is invalid.
getConfig(string|null $key = null, mixed $default = null) : mixed
Returns the config.
Reading the whole config:
$this->getConfig();Reading a specific value:
$this->getConfig('key');Reading a nested value:
$this->getConfig('some.nested.key');Reading with default value:
$this->getConfig('some-key', 'default-value');| string|null | $key | The key to get or null for the whole config. |
| mixed | $default | The return value when the key does not exist. |
Config value being read.
config(string|array|null $key = null, mixed|null $value = null, boolean $merge = true) : mixed
Gets/Sets the config.
Reading the whole config:
$this->config();Reading a specific value:
$this->config('key');Reading a nested value:
$this->config('some.nested.key');Setting a specific value:
$this->config('key', $value);Setting a nested value:
$this->config('some.nested.key', $value);Updating multiple config settings at the same time:
$this->config(['one' => 'value', 'another' => 'value']);| string|array|null | $key | The key to get/set, or a complete array of configs. |
| mixed|null | $value | The value to set. |
| boolean | $merge | Whether to recursively merge or overwrite existing config, defaults to true. |
When trying to set a key that is invalid.
Config value being read, or the object itself on write operations.
configShallow(string|array $key, mixed|null $value = null) : $this
Merge provided config with existing config. Unlike `config()` which does a recursive merge for nested keys, this method does a simple merge.
Setting a specific value:
$this->configShallow('key', $value);Setting a nested value:
$this->configShallow('some.nested.key', $value);Updating multiple config settings at the same time:
$this->configShallow(['one' => 'value', 'another' => 'value']);| string|array | $key | The key to set, or a complete array of configs. |
| mixed|null | $value | The value to set. |
channel(array $attrib = array(), array $elements = array(), string|null $content = null) : string
Returns an RSS `<channel />` element
| array | $attrib |
|
| array | $elements | Named array elements which are converted to tags |
| string|null | $content | Content ( |
An RSS <channel />
items(array $items, string|array|null $callback = null) : string
Transforms an array of data using an optional callback, and maps it to a set of `<item />` tags
| array | $items | The list of items to be mapped |
| string|array|null | $callback | A string function name, or array containing an object and a string method name |
A set of RSS <item /> elements
elem(string $name, array $attrib = array(), string|array|null $content = null, boolean $endTag = true) : string
Generates an XML element
| string | $name | The name of the XML element |
| array | $attrib | The attributes of the XML element |
| string|array|null | $content | XML element content |
| boolean | $endTag | Whether the end tag of the element should be printed |

_confirm(string $message, string $okCode, string $cancelCode = '', array $options = array()) : string
Returns a string to be used as onclick handler for confirm dialogs.
| string | $message | Message to be displayed |
| string | $okCode | Code to be executed after user chose 'OK' |
| string | $cancelCode | Code to be executed after user chose 'Cancel' |
| array | $options | Array of options |

_configWrite(string|array $key, mixed $value, boolean|string $merge = false) : void
Writes a config key.
| string|array | $key | Key to write to. |
| mixed | $value | Value to write. |
| boolean|string | $merge | True to merge recursively, 'shallow' for simple merge, false to overwrite, defaults to false. |
