大佬教程收集整理的这篇文章主要介绍了php-两次访问自定义验证器，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
我在Symfony2项目上有一个自定义验证器.
验证工作正常,但是以某种方式两次访问了该方法.
这是我的自定义验证器：My other resolved question
问题是下一个：
如您所见,错误消息显示两次.当我尝试在validate方法中进行var dump时,vardump也显示两次.知道为什么两次调用验证吗？当我使用$form-> bind($request);在我的控制器中.

这是树枝模板：
{% extends 'MerrinMainBundle::layout.html.twig' %}
{% block page_title %}
MDPI Conversion system (Merrin) 3.0 - New Conversion
{% endblock %}
{% block main %}
{% for flashmessage in app.session.flashbag.get('user-notice') %}
<div class="flash-notice">
{% autoescape false %}
{{ flashmessage }}
{% endautoescape %}
</div>
{% endfor %}
<h1>Create New Manuscript</h1>
{% if valid == false %}
<div class="error">
{{ form_errors(form) }}
{{ form_errors(form.doi) }}
{{ form_errors(form.publisher) }}
{{ form_errors(form.filE) }}
</div>
{% endif %}
<form action="{{ path }}" method="POST" {{ form_enctype(form) }}>
</form>
{% endblock %}
和控制器调用
public function createAction()
{
$em_scipub = $this->getDoctrine()->getManager();
$em_mdpipub = $this->getDoctrine()->getManager('mdpipub');
$enquiry = new Manuscript();
$formType = new NewManuscriptType();
$form = $this->createForm($formType, $enquiry);
$request = $this->getrequest();
$valid = true;
$error = '';
if ($request->isMethod('POST')) {
$form->bind($request);
if ($form->isValid()) {
... do something ...
$em_scipub->persist($enquiry);
$em_scipub->flush();
$flash_message = "<a href='edit/".$enquiry->getId()."'>New Manuscript</a> sucessfully created.";
$this->get('session')->getFlashBag()->set('user-notice', $flash_messagE);
return $this->redirect($this->generateUrl('MerrinMainBundle_new'));
}
else
$valid = false;
}
$path = $this->generateUrl('MerrinMainBundle_new');
return $this->render('MerrinMainBundle:Pages:new_conversion.html.twig.twig', array(
'valid' => $valid,
'path' => $path,
'form' => $form->createView(),
) );
}
编辑2：
验证功能：
public function validate($value, ConsTraint $consTraint)
{
$doi = $value->getDoi();
preg_match('/[^\/]+/i', $doi, $publisherDoiAbbr);
if($publisherDoiAbbr[0] !== $value->getPublisher()->getDoiAbbreviation()) {
$this->context->addViolation($consTraint->message_publisher_DOI);
}
else {
preg_match("/[a-z]+/",$doi, $journalDoiAbbr);
$em_mdpipub = $this->entitymanager;
$journal = $em_mdpipub->getRepository('MerrinMdpiPubBundle:Journal')->findOneBy(array('doi_abbreviation' => $journalDoiAbbr));
if($journal == null) {
$this->context->addViolation($consTraint->message_journal_DOI);
}
}
preg_match('/\d*$/i', $doi, $doiNumericPart);
if(strlen($doiNumericPart[0]) < 8) {
$this->context->addViolation($consTraint->message_volume_issue_firstpage_DOI);
}
}
和树枝模板：
{% extends 'MerrinMainBundle::layout.html.twig' %}
{% block page_title %}
MDPI Conversion system (Merrin) 3.0 - New Conversion
{% endblock %}
{% block main %}
{% for flashmessage in app.session.flashbag.get('user-notice') %}
<div class="flash-notice">
{% autoescape false %}
{{ flashmessage }}
{% endautoescape %}
</div>
{% endfor %}
<h1>Create New Manuscript</h1>
{% if valid == false %}
<div class="error">
{{ form_errors(form) }}
{{ form_errors(form.doi) }}
{{ form_errors(form.publisher) }}
{{ form_errors(form.filE) }}
</div>
{% endif %}
<form action="{{ path }}" method="POST" {{ form_enctype(form) }}>
<div style="float:left;">
<table width="700">
<tr>
<td>
{{ form_label(form.doi) }}
</td>
<td>
{{ form_widget(form.doi, { 'attr': {'size': 40} }) }}
</td>
</tr>
<tr>
<td>
{{ form_label(form.publisher) }}
</td>
<td>
{{ form_widget(form.publisher) }}
</td>
</tr>
<tr>
<td>
{{ form_label(form.filE) }}
</td>
<td>
{{ form_widget(form.filE) }}
</td>
</tr>
<tr>
<td>
</td>
<td>
<input class="submit-confirm-button" type="submit" name="update-text" value="submit" />
<a class="cancel-link" href="{{ path('MerrinMainBundle_homepage' ) }}">Cancel</a>
</td>
</tr>
</table>
</div>
{{ form_rest(form) }}
</form>
{% endblock %}
编辑3：
这是我将验证器应用于实体的方式：
/**
* Manuscript
*
* @IsDOI()
* @ORM\Table(name="manuscripts")
* @ORM\Entity(repositoryClass="Merrin\MainBundle\Repository\ManuscriptRepository")
* @ORM\HasLifecycleCallBACks
*
*/
class Manuscript
{
....
}

当我尝试推销
$form->getErrors();
array(2) {
[0]=>
object(Symfony\Component\Form\FormError)#507 (4) {
["message":"Symfony\Component\Form\FormError":private]=>
String(77) "The Publisher DOI abbreviation does not correspond to the DOI you filled in !"
["messageTemplate":protected]=>
String(77) "The Publisher DOI abbreviation does not correspond to the DOI you filled in !"
["messageParameters":protected]=>
array(0) {
}
["messagePluralization":protected]=>
NULL
}
[1]=>
object(Symfony\Component\Form\FormError)#542 (4) {
["message":"Symfony\Component\Form\FormError":private]=>
String(77) "The Publisher DOI abbreviation does not correspond to the DOI you filled in !"
["messageTemplate":protected]=>
String(77) "The Publisher DOI abbreviation does not correspond to the DOI you filled in !"
["messageParameters":protected]=>
array(0) {
}
["messagePluralization":protected]=>
NULL
}
}
解决方法:
如果您正在使用validation groups并将验证器应用于多个组,则可以这样做. @IsDOI()注释是什么意思？如果可能应用验证,则可以先在validation.yml中添加验证器,然后再通过此自定义注释添加验证器.
