在CakePHP中将beforeDelete中的变量传递给afterDelete()

Question

我想删除数据库中的记录后删除文件.因为我使用相关模型中的一些数据来构建图像路径,所以我需要在beforeDelete()中获取这些数据.

function beforeDelete() {
    $info = $this->find('first', array(
        'conditions' => array('Media.id' => $this->id),
    ));
}

function afterDelete() {
   unlink(WWW_ROOT . 'img/photos/' . $info['News']['related_id'] . "/" . $info['Media']['file']);       
}

如何正确访问$info数组afterDelete()？

Answer 1

您可以简单地在方法范围外声明此var.

private  $info;
function beforeDelete() {
$this->info = $this->find('first', array(
    'conditions' => array('Media.id' => $this->id),
));
}

function afterDelete() {
   unlink(WWW_ROOT . 'img/photos/' . $this->info ['News']['related_id'] . "/" . $this->info ['Media']    ['file']);       
}
