foo.barのようなクッキー名を使うときは、$encryptはtrueで

Posted at

環境

PHP: 5.3.3(CentOS)
CakePHP: 2.4.10

ドット記法

クッキー名にドット記法が使えますが、クッキーをwriteするとき、$encrypt = falseで書き込むと、readができなくなります。

cookie.php
$this->Cookie->write('foo.bar', 'hoge', false);

$hoge = $this->Cookie->read('foo.bar');

: Argument 1 passed to Hash::insert() must be an array, string given, called in /cakephp/lib/Cake/Controller/Component/CookieComponent.php on line 247 and defined [
Hash::get() - CORE/Cake/Utility/Hash.php, line 43
CookieComponent::read() - CORE/Cake/Controller/Component/CookieComponent.php, line 286

Cookie::readメソッドをみると、encryptされていることが必須か、_decryptメソッドでencryptされていないときの考慮がないように見えます。

ドット記法を使わなければ、問題はありませんし、とりあえず、$encrypt=trueで書き込んでおけば、問題はなさそうです。
