我已经关注了zf2专辑的例子。我现在正在尝试集成HTML Purifier。
这是模块 https://github.com/juriansluiman/Soflomo-Purifier#injecting-the-filtermanager
这是我构建输入过滤器的方式 http://framework.zend.com/manual/current/en/user-guide/forms-and-actions.html
namespace Album\Model;
// Add these import statements
use Zend\InputFilter\InputFilter;
use Zend\InputFilter\InputFilterAwareInterface;
use Zend\InputFilter\InputFilterInterface;
class Album implements InputFilterAwareInterface
{
public $id;
public $artist;
public $title;
protected $inputFilter; // <-- Add this variable
public function exchangeArray($data)
{
$this->id = (isset($data['id'])) ? $data['id'] : null;
$this->artist = (isset($data['artist'])) ? $data['artist'] : null;
$this->title = (isset($data['title'])) ? $data['title'] : null;
}
// Add content to these methods:
public function setInputFilter(InputFilterInterface $inputFilter)
{
throw new \Exception("Not used");
}
public function getInputFilter()
{
if (!$this->inputFilter) {
$inputFilter = new InputFilter();
$inputFilter->add(array(
'name' => 'id',
'required' => true,
'filters' => array(
array('name' => 'Int'),
),
));
$inputFilter->add(array(
'name' => 'artist',
'required' => true,
'filters' => array(
array('name' => 'StripTags'),
array('name' => 'StringTrim'),
),
'validators' => array(
array(
'name' => 'StringLength',
'options' => array(
'encoding' => 'UTF-8',
'min' => 1,
'max' => 100,
),
),
),
));
$inputFilter->add(array(
'name' => 'title',
'required' => true,
'filters' => array(
array('name' => 'StripTags'),
array('name' => 'StringTrim'),
),
'validators' => array(
array(
'name' => 'StringLength',
'options' => array(
'encoding' => 'UTF-8',
'min' => 1,
'max' => 100,
),
),
),
));
$this->inputFilter = $inputFilter;
}
return $this->inputFilter;
}
}
我收到以下错误。
因此,您得到ServiceNotFoundException:Zend \ Filter \ FilterPluginManager :: get无法为htmlpurifier获取或创建实例。这意味着过滤器插件管理器被懒惰地实例化,并且不知道htmlpurifier插件。
构建输入过滤器以利用此模块的正确方法是什么。非常感谢, 马特

您遇到的问题完全由SoflomoPurifier
文档中提到的问题引起:
由于您使用new InputFilter
手动实例化,因此该实例永远不会与其他模块提供的配置连接。
为了确保这种接线发生,我建议您创建一个新的InputFilter
子类,并将所有InputFilter::add()
次调用放入其init()
方法中:
use Zend\InputFilter\InputFilter:
class AlbumInputFilter extends InputFilter
{
public function init()
{
$this->add(array(
'name' => 'id',
'required' => true,
'filters' => array(
array('name' => 'Int'),
),
));
$this->add(array(
'name' => 'artist',
'required' => true,
'filters' => array(
array('name' => 'StripTags'),
array('name' => 'StringTrim'),
),
'validators' => array(
array(
'name' => 'StringLength',
'options' => array(
'encoding' => 'UTF-8',
'min' => 1,
'max' => 100,
),
),
),
));
$this->add(array(
'name' => 'title',
'required' => true,
'filters' => array(
array('name' => 'StripTags'),
array('name' => 'StringTrim'),
),
'validators' => array(
array(
'name' => 'StringLength',
'options' => array(
'encoding' => 'UTF-8',
'min' => 1,
'max' => 100,
),
),
),
));
}
}
更改您的相册模型构造函数以使用构造函数注入:
use Zend\InputFilter\InputFilterInterface;
class Album
{
// etc etc
public function __construct(InputFilterInterface $inputFilter)
{
$this->inputFilter = $inputFilter;
}
// etc etc
}
然后使用工厂注入它:
// in your Module.php
public function getServiceConfig()
{
return [
'factories' => [
'AlbumFactory' => function($serviceManager) {
$inputFilterManager = $serviceManager->get('InputFilterManager');
return function() use ($inputFilterManager) {
$inputFilter = $inputFilterManager->get(AlbumInputFilter::class);
return new Album($inputFilter)
}
}
]
];
}
使用输入过滤器调用InputFilterPluginManager::get()
FQCN将自动调用其构造函数,将其与其他模块连接起来,然后调用其init()
方法。
现在,您应该使用$album = new Album
服务创建专辑,而不是使用AlbumFactory
,而是正确注入输入过滤器:
$createAlbum = $serviceManager->get('AlbumFactory');
$album = $createAlbum()
显然,建议您将此工厂注入任何消费者(即控制器),而不是从服务管理器中提取,并可能将匿名功能重构为专用工厂类。
