假设您有一个这样的自定义规则:
var3
这很好,但是可以在此规则内添加其他规则吗?为了说明这一点,这是可能的:
<?php
class CheckFoo extends \Respect\Validation\Rules\AbstractRule
{
public function validate($input)
{
if ($input == 'foo')
return true;
else
return false;
}
}
class CheckFooException extends \Respect\Validation\Exceptions\ValidationException
{
public static $defaultTemplates = [
self::MODE_DEFAULT => [
self::STANDARD => '{{name}} must be foo',
],
self::MODE_NEGATIVE => [
self::STANDARD => '{{name}} must not be foo',
],
];
}
如果触发了class CheckFoo extends \Respect\Validation\Rules\AbstractRule
{
public function validate($input)
{
if (strlen($input) != 3)
return false;
if ($input == 'foo')
return true;
else
return false;
}
}
,如何在CheckFooException
内定义自定义错误消息?
答案 0 :(得分:1)
检查您正在使用的库,尤其是ValidationException类和AttributeException
的实现,应该可以在验证过程中通过ValidationException::getParam($propertyName)
从您的规则类中访问在规则类上声明的属性,您的Exception类。像这样:
class CheckFoo extends \Respect\Validation\Rules\AbstractRule
{
public $reason;
public function validate($input)
{
if (strlen($input) != 3) {
$this->reason = 'length';
return false;
}
if ($input !== 'foo') {
$this->reason = 'content';
return false;
}
return true;
}
}
然后访问它,以实现/重写方法ValidationException::chooseTemplate
,如下所示:
class CheckFooException extends \Respect\Validation\Exceptions\ValidationException
{
const INVALID_LENGTH = 0;
const INVALID_NAME = 1;
public static $defaultTemplates = [
self::MODE_DEFAULT => [
self::INVALID_NAME => '{{name}} must be foo',
self::INVALID_LENGTH => '{{name}} must be 3 characters long',
],
self::MODE_NEGATIVE => [
self::INVALID_NAME => '{{name}} must not be foo',
self::INVALID_LENGTH => '{{name}} must not be 3 characters long',
],
];
public function chooseTemplate()
{
return 'length' === $this->getParam('reason')
? self::INVALID_LENGTH
: self::INVALID_NAME;
}
}
测试:
v::checkFoo()->check('FOO'); // => "FOO" must be foo
v::checkFoo()->check('foox'); // => "foox" must be 3 characters long
或者,您可以将2条不同的规则与专用消息组合在一起(或者,就长度而言,琐碎的事,请使用已经由库提供的规则)。
