[英]Yii2: Either one field is required Validation
I have to implement the validation as mentioned in the title that either one of the two fields (email, phone) is required.我必须实现标题中提到的验证,即需要两个字段(电子邮件、电话)之一。 I am doing this in my model
:我在我的model
这样做:
[['email'],'either', ['other' => ['phone']]],
And this is the method:这是方法:
public function either($attribute_name, $params) {
$field1 = $this->getAttributeLabel($attribute_name);
$field2 = $this->getAttributeLabel($params['other']);
if (empty($this->$attribute_name) && empty($this->$params['other'])) {
$this->addError($attribute_name, Yii::t('user', "either {$field1} or {$field2} is required."));
return false;
}
return true;
}
When I access my index page, it gives me this error:当我访问我的索引页面时,它给了我这个错误:
Exception (Unknown Property) 'yii\\base\\UnknownPropertyException' with message 'Setting unknown property: yii\\validators\\InlineValidator::0'异常(未知属性)“yii\\base\\UnknownPropertyException”,消息为“设置未知属性:yii\\validators\\InlineValidator::0”
Any help?有什么帮助吗?
If you don't care that both fields show an error when the user provides neither of both fields:如果你不关心,当用户提供这两个领域的既不是这两个字段显示一个错误:
This solutions is shorter than the other answers and does not require a new validator type/class:此解决方案比其他答案更短,并且不需要新的验证器类型/类:
$rules = [
['email', 'required', 'when' => function($model) { return empty($model->phone); }],
['phone', 'required', 'when' => function($model) { return empty($model->email); }],
];
If you want to have a customized error message, just set the message
option:如果您想自定义错误消息,只需设置message
选项:
$rules = [
[
'email', 'required',
'message' => 'Either email or phone is required.',
'when' => function($model) { return empty($model->phone); }
],
[
'phone', 'required',
'message' => 'Either email or phone is required.',
'when' => function($model) { return empty($model->email); }
],
];
The rule should be:规则应该是:
['email', 'either', 'params' => ['other' => 'phone']],
And method:和方法:
public function either($attribute_name, $params)
{
$field1 = $this->getAttributeLabel($attribute_name);
$field2 = $this->getAttributeLabel($params['other']);
if (empty($this->$attribute_name) && empty($this->{$params['other']})) {
$this->addError($attribute_name, Yii::t('user', "either {$field1} or {$field2} is required."));
}
}
Improved variant改进型
['gipsy_team_name', 'either', 'skipOnEmpty'=>false, 'params' => ['other' => 'poker_strategy_nick_name']],
['vkontakte', 'either', 'skipOnEmpty'=>false, 'params' => ['other' => ['odnoklasniki','odnoklasniki']]],
Added 'skipOnEmpty'=>false for forcing validating and 'other' can be array添加了'skipOnEmpty'=>false用于强制验证并且 'other' 可以是数组
/**
* validation rule
* @param string $attribute_name
* @param array $params
*/
public function either($attribute_name, $params)
{
/**
* validate actula attribute
*/
if(!empty($this->$attribute_name)){
return;
}
if(!is_array($params['other'])){
$params['other'] = [$params['other']];
}
/**
* validate other attributes
*/
foreach($params['other'] as $field){
if(!empty($this->$field)){
return;
}
}
/**
* get attributes labels
*/
$fieldsLabels = [$this->getAttributeLabel($attribute_name)];
foreach($params['other'] as $field){
$fieldsLabels[] = $this->getAttributeLabel($field);
}
$this->addError($attribute_name, \Yii::t('poker_reg', 'One of fields "{fieldList}" is required.',[
'fieldList' => implode('"", "', $fieldsLabels),
]));
}
