[英]Phalcon optional fields in model validation
i have validated some fields in Phalcon model like below 我已经验证了Phalcon模型中的某些字段,如下所示
class Ads extends Phalcon\Mvc\Collection
{
public function validation()
{
$this->validate(
new InclusionIn(
array(
"field" => "type",
"message" => "Type must be: mechanical or virtual",
"domain" => array("Mechanical", "Virtual")
)
)
);
$this->validate(
new Numericality(
array(
"field" => "price",
"message" => "Price must be numeric"
)
)
);
return $this->validationHasFailed() != true;
}
}
How can i define some fields as optional fields and some fields as required fields in validation? 如何在验证中将某些字段定义为可选字段并将某些字段定义为必填字段?
optional fields: 可选字段:
for example when price exist, validate it, when not price, ignore it. 例如,当价格存在时,对其进行验证;当价格不存在时,对其进行忽略。
required fields : 必填字段:
when price not exist, don't insert data into database and return related error message. 当价格不存在时,请勿将数据插入数据库并返回相关错误消息。
use allowEmpty
as 使用
allowEmpty
作为
$this->validate(
new Numericality(
array(
"field" => "price",
"message" => "Price must be numeric",
"allowEmpty" => true
)
)
);
When the price field is empty, it will not validate. 当价格字段为空时,它将不会验证。
