无法使用 Twig 获取输入值

Can't get input value with Twig

你好,我试图传递一些参数,但我不知道如何使用 twig 获取输入值,这是我的代码: 好的,首先我使用此 detailsaction 显示博客详细信息,它还呈现一个表单以向博客添加评论;

public function detailsAction(Request $request,Blog $blog){

        $user=$this->getUser();
        if($user==null)
            return $this->redirectToRoute('fos_user_security_login');
        $add_comment = new CommentaireBlog();
        $em = $this->getDoctrine()->getManager();

        $comments = $em->getRepository(CommentaireBlog::class)->findByBlog($blog);
        $add_comment->setBlog($blog);
        $add_comment->setUser($user);
        $add_comment->setDate( new \DateTime());

        $form = $this->createFormBuilder($add_comment)

            ->add('contenu', TextareaType::class)

            ->getForm();

        if ($request->getMethod() == 'POST') {
            $form->handleRequest($request);

            if ($form->isSubmitted() && $form->isValid()) {
                $add_comment = $form->getData();
                $em = $this->getDoctrine()->getEntityManager();
                $em->persist($add_comment);
                $em->flush();

                return $this->redirectToRoute('blog_details', array('id' => $blog->getId()));
            }
        }


        return $this->render('blog/details.html.twig', array(
            'form' => $form->createView(),
            'comment' => $add_comment,
            'blog' => $blog,
            'comments'=>$comments,
        ));

    }

树枝页面:

   {{ form_start(form) }}
                                <div class="row form-group">

                                    <div class="col col-md-3"><label class=" form-control-label">Votre Commentaire  </label></div>
                                    <div class="col-12 col-md-9"> {{ form_widget(form.contenu, { 'attr': {'class': 'form-control'} }) }}<small class="form-text text-muted"></small></div>
                                    <button type="submit" class="btn btn-default">Envoyer</button>
                                    <div class="col-12 col-md-9">
                                    </div>
                                </div>
                                    {{ form_end(form) }}

现在我想做的是,在有人添加评论及其(racist/verbual 滥用..)后,其他用户可以报告该评论并发送一封邮件,所以我使用了 reportAction,这需要三个参数消息和评论 ID

的原因
public function reportAction($msg,$type,$id)
    {

    }

我仍然没有在里面写,因为首先我需要输入的值,所以我去了树枝页面,我做了这个小表格来获取输入,但不知道如何获取值 这是表格:

<div class="modal-body">
  <form id="lala" method="GET">
    <label for="cars">Reason:</label>
            <select id="reportreason">
                <option value="Inappropriate Content">Inappropriate Content</option>
                 <option value="Spam">Spam</option>
                <option value="Racism">Racism</option>
                <option value="Nudity">Nudity</option>
                 <option value="Other">Other</option>
      </select>
    <div class="form-group">
        <label for="message-text" class="col-form-label">Message:</label>
        <textarea id="reportmessage" class="form-control" id="message-text"></textarea>
    </div>
  </form>
</div>
 <div class="modal-footer">
    <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
    <a id="reportlink" href="{{ path('comment_report', { 'msg': form.vars.data.reportmessage ,'type': form.vars.data.reportreason, 'id': comment.id  }) }}" type="button" class="btn btn-primary">Send message</a>
</div>

这是 yml 文件:

blog_details:
    path:      /{id}/details
    defaults: { _controller: "BlogBundle:Blog:details" }
    methods:  [GET, POST]
comment_report:
    path:     /{msg}/{type}/{id}/report
    defaults: { _controller: "BlogBundle:Blog:report" }
    methods:  [GET, POST]

但我现在收到此错误: 属性 "reportmessage" 和方法 "reportmessage()"、"getreportmessage()"/"isreportmessage()" 或“__call()” 中的任何一种都不存在并且具有 public 访问 class "BlogBundle\Entity\CommentaireBlog".

那么我如何使用 twig 获取输入的值?

我不知道你为什么这样写你的 path 调用,但是你想在你的路由中使用的变量不应该有任何圆括号。以下代码应该有效:

<a 
  href="{{ path('comment_report', { 'msg': form.reportmessage.value ,'type': form.reportreason.value, 'id': comment.id  }) }}" 
  type="button"
  class="btn btn-primary">
     Send message
</a>

Twig 对象语法 https://twigfiddle.com/01iobj

实际上,twig 错误消息是说在您的 path() 参数中,您正在传递一个没有关联键的对象 {value} 正确的语法是 {key: value}[value],类似于 JSON 语法。

{ 
   "key1": { "key1a": "value1a" }, 
   "key2": ["value2"], 
   "key3": "value3" 
}

结果

$_GET = array(
    'key1' => array('key1a' => 'value1a'), 
    'key2' => array('value2'), 
    'key3' => 'value3'
);

一种不同的方法

看看你想做什么,你需要重构你的方法。

首先仅针对评论更改您的控制器路径。

blog_details:
    path:      /{id}/details
    defaults: { _controller: "BlogBundle:Blog:details" }
    methods:  [GET, POST]
comment_report:
    path:     /{comment}/report
    defaults: { _controller: "BlogBundle:Blog:report" }
    methods:  [POST]

接下来为您的模式创建一个表单实例,这将允许您使用 FormInstance 在其他地方呈现和验证提交的表单。确保进行所有验证,并且您不必为同一表单更新不同的脚本。

/* /src/Form/CommentReportForm.php */

namespace App\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type as Form;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Component\Validator\Constraints as Assert;

class CommentReportForm extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
         $builder
             ->add('reason', Form\ChoiceType::class [
                'choices' => [
                     'Inappropriate Content' => 'Inappropriate Content',
                     'Spam' => 'Spam',
                     'Racism' => 'Racism',
                     'Nudity' => 'Nudity',
                     'Other' => 'Other'
                ]
            ])
             ->add('message', Form\TextType::class, [
                'constraints' => [
                    new Assert\Length(['min' => 10]),
                    new Assert\NotBlank(),
                ],
            ]);
    }

    public function getBlockPrefix()
    {
       return 'report_comment_form';
    }
}

接下来,相应地更新您的控制器操作。

public function detailsAction(Request $request, Blog $blog)
{
    if (!$user = $this->getUser()) {
        //this should be handled in your firewall configuration!!!!
        return $this->redirectToRoute('fos_user_security_login');
    }
    $em = $this->getDoctrine()->getManager();

    $add_comment = new CommentaireBlog();
    $add_comment->setBlog($blog);
    $add_comment->setUser($user);
    $add_comment->setDate(new \DateTime());

    $form = $this->createFormBuilder($add_comment)
        ->add('contenu', TextareaType::class)
        ->getForm();
    $form->handleRequest($request);
    if ($form->isSubmitted() && $form->isValid()) {
        //Symfony form sets values for the model by_reference
        $em->persist($add_comment);
        $em->flush();

        return $this->redirectToRoute('blog_details', array('id' => $blog->getId()));
    }

    /*
    * create the report form
    */
    $reportForm = $this->createForm(\App\Form\CommentReportForm::class);
    $reportForm->handleRequest($request);

    return $this->render('blog/details.html.twig', array(
        'form' => $form->createView(),
        'comment' => $add_comment,
        'blog' => $blog,
        'comments'=> $em->getRepository(CommentaireBlog::class)->findByBlog($blog),
        /*
         * give the report form a different name in twig
         */
        'report_form' => $reportForm->createView(),
    ));

}
public function reportAction(Request $request, CommentaireBlog $comment)
{
    $reportForm = $this->createForm(\App\Form\CommentReportForm::class);
    $reportForm->handleRequest($request);
    /** @var array|string[message, reason] */
    $reportData = $reportForm->getData();
    /*
      array( 'reason' => 'value', 'message' => 'value' )
     */
    dump($reportData);
    if ($reportForm->isSubmitted() && $reportForm->isValid()) {
        //send email

        //redirect to success message
    }
    //display an error message
}

最后更新您的视图以支持模态中的新表单。

<div class="modal-body">
  {{ form_start(report_form, { action: path('comment_report', { comment: comment.id }) })
  {{ form_label(report_form.reason) }}
  {{ form_widget(report_form.reason) }}
  <div class="form-group">
      {{ form_label(report_form.message) }}
      {{ form_widget(report_form.message) }}
  </div>
  {{ form_end(report_form) }}
</div>
<div class="modal-footer">
    <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
    <button type="submit" class="btn btn-primary">Send message</button>
</div>

作为建议,我强烈建议您在数据库中记录提交的报告,以作为案例日志和报告状态。我的方法将帮助您完成大部分工作,您只需要创建您的 App\Entity\CommentReport 实体,并可选地关联到 CommentaireBlog 实体。这将被传递到表单并将 data_class 添加到表单选项解析器,模仿您在其他数据库表单中所做的。
