Example
Use case: remember the current URL to return to after adding a new record in a different (related) controller, for instance create a new contact to add to an invoice being edited.
InvoiceController / actionUpdate:
Url::remember(Url::current(), 'returnInvoice');
ContactController / actionCreate:
if ($model->save()) {
$return = Url::previous('returnInvoice');
if ($return) {
return $this->redirect($return);
}
// ...
}
You can reset the remembered URL once you're done:
InvoiceController / actionUpdate:
if ($model->save()) {
Url::remember(null, 'returnInvoice');
// ...
}
The key name - returnInvoice in this example - is optional.
