[英]How can I add a custom Validator to Respect's Validation library
The awesome Respect Validation library comes with lots of built-in validators, like string(), alpha(), et cetera. 令人敬畏的Respect Validation库带有许多内置验证器,如string(),alpha()等等。 I want to add self-defined validators to the library, eg., I want to be able to do this:
我想在库中添加自定义验证器,例如,我希望能够这样做:
Validator::myCustomValidator()->assert( $input );
I just discovered that's it not very complicated, but I had to look at the library's source code to find out, so I'm posting this self-answered question here for future reference. 我刚刚发现它并不是很复杂,但我不得不查看图书馆的源代码才能找到,所以我在这里发布这个自我回答的问题以备将来参考。
Define a validation class and an accompanying exception class in the proper namespace, and the Validation library will automagically use them to validate your data, as such: 在适当的命名空间中定义验证类和附带的异常类,验证库将自动使用它们来验证您的数据,如下所示:
myCustomValidator.php: myCustomValidator.php:
<?php
namespace Respect\Validation\Rules;
class myCustomValidator extends AbstractRule
{
public function validate($input)
{
return true; // Implement actual check here; eg: return is_string($input);
}
}
myCustomValidatorException.php: myCustomValidatorException.php:
<?php
namespace Respect\Validation\Exceptions;
class myCustomValidatorException extends ValidationException
{
public static $defaultTemplates = array(
self::MODE_DEFAULT => array(
self::STANDARD => '{{name}} must ... ', // eg: must be string
),
self::MODE_NEGATIVE => array(
self::STANDARD => '{{name}} must not ... ', // eg: must not be string
)
);
}
As long as these files are included in your project, Validator::myCustomValidator()->assert( $input );
只要这些文件包含在您的项目中,
Validator::myCustomValidator()->assert( $input );
should now work. 现在应该工作。
This obviously relies on naming conventions, so be sure to use the class name to call the self-defined validator and you should be set. 这显然依赖于命名约定,因此请务必使用类名来调用自定义验证器,并且应该进行设置。
