Cakephp 数据验证：检查是否至少填充了一个字段并且多个规则未验证

Question

伙计们，

我正在尝试确保至少填充两个字段（姓氏或电子邮件）中的一个。每个字段也有多个规则。我正在使用 CakePHP 2.4.2 版。

我目前遇到的问题是，在多次更新和/或移动使用“last”、“allowEmpty”、“required”等之后，这些字段根本没有验证，或者填充字段时未执行所有规则。

非常感谢任何有关如何修改以下代码以实现以下行为的建议： 1. 必须填写两个字段之一； 2. 附加到每个字段的其他规则也必须有效（即，如果姓氏通过，则它必须介于 2 到 45 个字符之间，并且只能包含字母数字）

这是模型代码：

public $validate = array(
    'last_name'=> array(
        'needOne' => array (
            'required' => FALSE,
            'allowEmpty' => TRUE,
            'last' => TRUE,
            'rule' => array('checkOne','last_name'),
            'message' => 'You must enter at least a contact name or email address.'
         ),
        'alphaNumeric' => array(
            'rule'   => 'alphaNumeric',
            'message'  => 'Alphabets and numbers only'
        ),
        'between' => array(
            'rule'  => array('between', 2, 45),
            'message' => 'Between 2 to 45 characters'
        )
    ),
    'email' => array(
        'needOne' => array (
            'required' => FALSE,
            'allowEmpty' => TRUE,
            'last' => TRUE,
            'rule' => array('checkOne','email'),
            'message' => 'You must enter at least a contact name or email address.'
         ),
        'emailAddress' => array (
            'last' => TRUE,
            'rule' => array('email', FALSE),
            'message'  => 'A valid Email address is required'
         )
    )
);

// Ensure at least the last name or email field value is provided
function checkOne($field) {
    if(!empty($this->data[$this->User]['last_name']) || 
        !empty($this->data[$this->User]['email'])){
        return true;
    } else {
        return false;
    }
}

提前致谢！

非常感谢vicocamacho。我坚持下去，除了您的建议外，还发现解决方案还在于在视图中添加“必需”=> false。

对于遇到此问题的其他人来说，这是可行的解决方案：

型号：

public $validate = array(
    'last_name'=> array(
        'needOne' => array (
        'rule' => 'checkOne',
        'message' => 'You must enter at least a contact name or email address.'
    ),
    'alphaNumeric' => array(
        'rule' => 'alphaNumeric',
        'message'  => 'Alphabets and numbers only',
        'allowEmpty' => TRUE
    ),
    'between' => array(
        'rule' => array('between', 2, 45),
        'message' => 'Between 2 to 45 characters',
        'allowEmpty' => TRUE
    )
),
'email' => array(
    'needOne' => array (
        'rule' => 'checkOne',
        'message' => 'You must enter at least a contact name or email address.'
    ),
    'emailAddress' => array (
        'rule' => 'email',
        'message' => 'A valid Email address is required',
        'allowEmpty' => TRUE
    )
)
);

// Ensure at least the last name or email field value is provided
public function checkOne($data) {
    if(!empty($this->data[$this->alias]['last_name']) 
    || !empty($this->data[$this->alias]['email'])) {
        return TRUE;
    } else {
        return FALSE;
    }
}

视图/字段（我正在使用 Bootstrap）：

echo $this->Form->input('last_name', array(
        'required' => false,
        'fieldset' => false,
        'label' => false,
        'before' => '<label class="control-label">Last Name <span class="one-required">*</span></label>',
        'class' => 'form-control',
        'placeholder' => 'Last Name',
        'div' => 'form-group col-sm-12',
        'error' => array(
            'attributes' => array(
                'wrap' => 'div', 
                'class' => 'alert alert-danger'
            )
        )
    )
);

echo $this->Form->input('email', array(
        'required' => false,
        'fieldset' => false,
        'label' => false,
        'before' => '<label class="control-label">Email <span class="one-required">*</span></label>',
        'after' => '',
        'class' => 'form-control',
        'div' => 'form-group col-sm-12 col-xs-12',
        'error' => array(
            'attributes' => array(
                'wrap' => 'div', 
                'class' => 'alert alert-danger'
            )
        )
    )
);

谢谢。

Answer 2

编写一个自定义规则，该规则将检查两个字段中的一个是否不为空，并在这两个字段上使用该规则。并将其他规则的 allowEmpty 设置为 true。

Answer 3

您应该在所有不检查字段是否存在的规则中允许Empty，我更新了您的代码以便您了解我的意思，您还需要将checkOne 中的$this->User 索引更改为@987654323 @ 否则会一直返回false:

public $validate = array(
    'last_name'=> array(
        'alphaNumeric' => array(
            'rule'   => 'alphaNumeric',
            'message'  => 'Alphabets and numbers only',
            'allowEmpty' => true
        ),
        'between' => array(
            'rule'  => array('between', 2, 45),
            'message' => 'Between 2 to 45 characters',
            'allowEmpty' => true
        )
    ),
    'email' => array(
        'needOne' => array (
            'rule' => 'checkOne',
            'message' => 'You must enter at least a contact name or email address.'
        ),
        'emailAddress' => array (
            'allowEmpty' => true,
            'rule' => 'email',
            'message'  => 'A valid Email address is required'
        )
    )
);

// Ensure at least the last name or email field value is provided
function checkOne($field) {
        if(
            !empty($this->data[$this->alias]['last_name']) ||
            !empty($this->data[$this->alias]['email'])
        )
        {
                return true;
        } else {
                return false;
        }
}
