这个查找条件有什么问题

Question

以下工作，它为我提供了删除为空的所有数据：

$conditions = array('OR' => array(

    'Task.deleted' => null,


    )

);


$this->set('tasks', $this->Task->find('all', array('recursive' => 2, 'conditions' => $conditions)));

类似下面给出了删除为0的所有数据

$conditions = array('OR' => array(

 'Task.deleted' => 0,


)

); //...

但如果我像下面这样组合它，它会给我删除的数据为空，但不包括删除的数据为0。

$conditions = array('OR' => array(

        'Task.deleted' => 0,
        'Task.deleted' => null

        )

);

Answer 1

您正尝试将PHP数组键'Task.deleted'设置两次，覆盖它。请执行以下任一操作：

'Task.deleted' => array(0, null)

或：

'OR' => array(
    array('Task.deleted' => 0),
    array('Task.deleted' => null)
)

或

$conditions = array(
    'OR' => array(
       array('Task.deleted' => 0),
      array('Task.deleted' => null)
    )
    );

$this->set('tasks', $this->Task->find('all', array('recursive' => 2, 'conditions' => $conditions)));
