Question

嘿伙计们我试图从我的events_controller.php文件中的数组中获取值。事件属于实体和实体hasMany事件。我需要这个值来执行一些其他逻辑，但我真的卡住了，我知道这应该是一件容易的事情。

我试图从这个数组中获取Entity.user_id的值。

Array
(
[Event] => Array
    (
        [id] => 19
        [entity_id] => 8
        [name] => new event
        [time_start] => 2011-02-26 19:09:00
        [time_end] => 2011-02-26 19:09:00
        [dateStart] => 0000-00-00
        [dateEnd] => 0000-00-00
        [description] => jgiuguygo
        [ageRange] => 67
    )

[Entity] => Array
    (
        [id] => 8
        [user_id] => 14
        [location_id] => 15
        [type] => EVENT
    )

[Eventfeedback] => Array
    (
    )
)

使用此代码获得的上述矩阵：

$value = $this->Event->read();
pr($value);

现在这是我能得到的......

Array
(
[Entity] => Array
    (
        [user_id] => 14
    )

[Event] => Array
    (
        [id] => 19
    )

[Eventfeedback] => Array
    (
    )
)

使用此代码

$value = $this->Event->read('Entity.user_id');
pr($value);

最后一次尝试我得到了这个数组

Array
(
[Entity] => Array
    (
        [id] => 1
        [user_id] => 11
        [location_id] => 8
        [type] => sdfsdfdsf
    )

[User] => Array
    (
        [id] => 11
        [firstName] => luis
        [lastName] => pooya
        [username] => admin
        [password] => 94c882c8506497a9f031ca5a4db6d0143c97fe45
        [role] => admin
        [email] => some
    )

[Location] => Array
    (
        [id] => 8
        [name] => First Nation University of Canada
        [xCoordinate] => 0
        [yCoordinate] => 0
    )

[Establishment] => Array
    (
    )

[Event] => Array
    (
    )

[Vmachine] => Array
    (
    )
)

使用此代码

$value = $this->Event->Entity->find('user_id');
pr($value);

希望有人可以帮助我。在此先感谢.Luis

Answer 1

我不确定我是否正确理解你。但是在你的例子中获得user_id就像

$value = $this->Event->read('Entity.user_id');
pr($value['Entity']['user_id']);

Answer 2

$event = $this->Event->read();
$userId = $event['Entity']['user_id'];
