CP/URL Service

Simple Example

Building URLs in the Control Panel is a common, but exacting task. We have a CP/URL Service to make building these URLs simple. For example:

$url = ee('CP/URL', 'publish/create/1');

The service automatically takes care of appending the session ID when it is required. For more complex URLs we also provide means of adding arbitrary query string variables using the make method:

$url = ee('CP/URL')->make('publish/edit', array('filter_by_channel' => 1));

Or:

$url = ee('CP/URL', 'publish/edit')
  ->setQueryStringVariable('filter_by_channel', 1);

When to use compile()

The CP/URL object has a magic __toString() method that compiles the object into a string when the object is treated as a string (see: PHP’s documentation on the magic __toString() method for more information). The compile() method exists for those occasions when the object is treated as an object but you need a string instead. As per PHP’s documentation on arrays: “Arrays and objects can not be used as keys. Doing so will result in a warning: Illegal offset type.“ You will also want to compile the object when you want to JSON encode the URL otherwise you will get a JSON object instead of a string.

For example:

$breadcrumb = array(
  ee('CP/URL', 'addons/settings/fortune_cookie')->compile() => lang('fortune_cookie_management')
);

ee()->javascript->set_global(array(
  'fortune_cookie.autosave.URL' => ee('CP/URL', 'addons/settings/fortune_cookie/autosave/')->compile()
));

CP/URL Service Methods

class ExpressionEngine\Library\CP\URLFactory

make($path, $qs = array(), $cp_url = '', $session_id = NULL)

Makes a URL object.

makeFromString($url)

Makes a URL object from a string.

getCurrentUrl()

Makes a URL object representing the requested URL.

decodeUrl($url)

Decodes a base64 encoded, serialized URL object.

CP/URL Object Methods

class ExpressionEngine\Library\CP\URL

setQueryStringVariable($key, $value)

Sets a key and value which will become the Query String of the request

addQueryStringVariables($values)

Sets a values in bulk which will become the Query String of the request

compile()

Compiles and returns the URL as a string. Typically this is used when you need to use a URL as an array key, or want to json_encode() a URL.

__toString()

When accessed as a string simply complile the URL and return that.
