htmlRedirect()

Create Redirect for AJAX Requests which output goes into HTML content.


    public
                    htmlRedirect([mixed $url = "" ]) : mixed

Is an alternative method to redirect, for ajax responses.

Parameters

$url : mixed = ""

init()

Initializes the object.


    public
                    init() : mixed

isNotInterceptedAction()

Check if action cannot be intercepted


    public
                    isNotInterceptedAction([string|null $actionId = null ]) : bool

Parameters

$actionId : string|null = null: , NULL - to use current action

Return values

bool

off()

Detaches an existing event handler from this component.


    public
                    off(string $name[, callable|null $handler = null ]) : bool

This method is the opposite of [[on()]].

Note: in case wildcard pattern is passed for event name, only the handlers registered with this wildcard will be removed, while handlers registered with plain names matching this wildcard will remain.

Parameters

$name : string: event name
$handler : callable|null = null: the event handler to be removed. If it is null, all handlers attached to the named event will be removed.

Return values

bool —

if a handler is found and detached

on()

Attaches an event handler to an event.


    public
                    on(string $name, callable $handler[, mixed $data = null ][, bool $append = true ]) : mixed

The event handler must be a valid PHP callback. The following are some examples:

function ($event) { ... }         // anonymous function
[$object, 'handleClick']          // $object->handleClick()
['Page', 'handleClick']           // Page::handleClick()
'handleClick'                     // global function handleClick()

The event handler must be defined with the following signature,

function ($event)

where $event is an [[Event]] object which includes parameters associated with the event.

Since 2.0.14 you can specify event name as a wildcard pattern:

$component->on('event.group.*', function ($event) {
    Yii::trace($event->name . ' is triggered.');
});

Parameters

$name : string: the event name
$handler : callable: the event handler
$data : mixed = null: the data to be passed to the event handler when the event is triggered. When the event handler is invoked, this data can be accessed via [[Event::data]].
$append : bool = true: whether to append new event handler to the end of the existing handler list. If false, the new handler will be inserted at the beginning of the existing handler list.

prependPageTitle()

Prepend a page title.


    public
                    prependPageTitle(string $title) : mixed

Parameters

$title : string

redirect()

Redirects the browser to the specified URL.


    public
                    redirect(mixed $url[, mixed $statusCode = 302 ]) : Response

Parameters

$url : mixed

the URL to be redirected to. This can be in one of the following formats:

a string representing a URL (e.g. "https://example.com")
a string representing a URL alias (e.g. "@example.com")
an array in the format of [$route, ...name-value pairs...] (e.g. ['site/index', 'ref' => 1]) [[Url::to()]] will be used to convert the array into a URL.

Any relative URL that starts with a single forward slash "/" will be converted into an absolute one by prepending it with the host info of the current request.

$statusCode : mixed = 302

the HTTP status code. Defaults to 302. See https://tools.ietf.org/html/rfc2616#section-10 for details about HTTP status code

Return values

Response —

the current response object

refresh()

Refreshes the current page.


    public
                    refresh([string $anchor = '' ]) : Response

This method is a shortcut to [[Response::refresh()]].

You can use it in an action by returning the [[Response]] directly:

// stop executing this action and refresh the current page
return $this->refresh();

Parameters

$anchor : string = '': the anchor that should be appended to the redirection URL. Defaults to empty. Make sure the anchor starts with '#' if you want to specify it.

Return values

Response —

the response object itself

render()

Renders a view and applies layout if available.


    public
                    render(string $view[, array<string|int, mixed> $params = [] ]) : string

The view to be rendered can be specified in one of the following formats:

path alias (e.g. "@app/views/site/index");
absolute path within application (e.g. "//site/index"): the view name starts with double slashes. The actual view file will be looked for under the [[Application::viewPath|view path]] of the application.
absolute path within module (e.g. "/site/index"): the view name starts with a single slash. The actual view file will be looked for under the [[Module::viewPath|view path]] of [[module]].
relative path (e.g. "index"): the actual view file will be looked for under [[viewPath]].

To determine which layout should be applied, the following two steps are conducted:

In the first step, it determines the layout name and the context module:

If [[layout]] is specified as a string, use it as the layout name and [[module]] as the context module;
If [[layout]] is null, search through all ancestor modules of this controller and find the first module whose [[Module::layout|layout]] is not null. The layout and the corresponding module are used as the layout name and the context module, respectively. If such a module is not found or the corresponding layout is not a string, it will return false, meaning no applicable layout.

In the second step, it determines the actual layout file according to the previously found layout name and context module. The layout name can be:

a path alias (e.g. "@app/views/layouts/main");
an absolute path (e.g. "/main"): the layout name starts with a slash. The actual layout file will be looked for under the [[Application::layoutPath|layout path]] of the application;
a relative path (e.g. "main"): the actual layout file will be looked for under the [[Module::layoutPath|layout path]] of the context module.

If the layout name does not contain a file extension, it will use the default one .php.

Parameters

$view : string: the view name.
$params : array<string|int, mixed> = []: the parameters (name-value pairs) that should be made available in the view. These parameters will not be available in the layout.

Return values

string —

the rendering result.

renderAjax()

Renders a view in response to an AJAX request.


    public
                    renderAjax(string $view[, array<string|int, mixed> $params = [] ]) : string

This method is similar to [[renderPartial()]] except that it will inject into the rendering result with JS/CSS scripts and files which are registered with the view. For this reason, you should use this method instead of [[renderPartial()]] to render a view to respond to an AJAX request.

Parameters

$view : string: the view name. Please refer to [[render()]] on how to specify a view name.
$params : array<string|int, mixed> = []: the parameters (name-value pairs) that should be made available in the view.

string —

the rendering result.

                    renderFile(string $file[, array<string|int, mixed> $params = [] ]) : string
