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()
));
