在依赖字段上的Cakephp自定义验证

Question

我需要在我的模型中进行自定义验证，其中一个字段不能重复，而两个字段将区分它，例如组合键。 就像下面。

    public $validate = array(
    'field1' => array(
        'required' => array(
            'rule' => 'notEmpty',
            'message' => 'Can\'t left blank.'
        ),
        'unique' => array(
            'rule' => array('validateNumberType'),
            'message' => 'Already exist'
        ),
        )
    );
    function validationRule() {
    $validation_var = $this->find('first', array('conditions' => array('Model.field1' => 'field1', 'Model.field2' => 'field2')));
    return $validation_var;
}

我试过了，但是没用，功能可能不正确吗？

Answer 1

var $validate = array(
   'slug' => array(
        'rule' => 'validationRule',
        'message' => 'error message'
    )
);
function validationRule($check) {
    //validation
    //$check is value of the field
    //$this->data is value of whole submited form

    // return true if validate, false either
}

Answer 2

在规则中定义的函数名称更改为validateNumberType ，例如：

public $validate = array(
    'field1' => array(
        'required' => array(
            'rule' => 'notEmpty',
            'message' => 'Can\'t left blank.'
        ),
        'unique' => array(
            'rule' => array('validateNumberType'),
            'message' => 'Already exist'
        ),
        )
    );
    function validateNumberType() {
    $validation_var = $this->find('first', array('conditions' => array('Model.field1' => 'field1', 'Model.field2' => 'field2')));
    return $validation_var;
}

例如，请参见此处： 依赖类型的验证

Answer 3

var $validate = array(
'slug' => array(
'rule' => 'validationRule',
'message' => 'error message'
)
);
function validationRule($check) {
//validation
//$check is value of the field
}
