这是我的桌子。这里employees_supervisers_id是employees_id. 我们如何通过cakephp获取递归数据？

要构建一棵树，您需要使用TreeBehavior，并在模型中具有parent_id和/或lft字段rght。

lft并且rght用于MPTT数据

在您的情况下，您可以配置行为以使用您的employees_supervisers_id字段

我认为您正在尝试在同一个表中的记录之间创建父/子关系。如果这是您所要求的，您可以在 Employee 模型中创建这些关系，如下所示：

public $belongsTo = array(
    'Supervisor' => array(
        'className' => 'Employee',
        'foreignKey' => 'employee_id',
        'conditions' => '',
        'fields' => '',
        'order' => ''
    ),
);

public $hasMany = array(
    'Underlings' => array(
        'className' => 'Employee',
        'foreignKey' => 'employees_supervisers_id',
        'dependent' => false,
        'conditions' => '',
        'fields' => '',
        'order' => '',
        'limit' => '',
        'offset' => '',
        'exclusive' => '',
        'finderQuery' => '',
        'counterQuery' => ''
    ),
);

如果您创建模型之间的关系，CakePHP 默认会获取它。

如果你这样做：

$employees = $this->Employee->find('all');

并且您已经创建了模型之间的关系，您将能够通过以下方式访问递归数据：

$employees['Employee']['Supervisor']['employees_firstname'];

我建议您查看有关模型之间链接的文档：http: //book.cakephp.org/2.0/en/models/associations-linking-models-together.html
