Symfony:CreateForm/为什么我的textarea没有出现? [英] Symfony : CreateForm / Why my textarea do not appear?

问题描述

我在用Symfony创建的表单中显示文本区域时遇到问题.

I have a problem to display a textarea from a form I've created with Symfony.

文本区域显示为html，但在CSS中没有 display:block .需要清楚的是，css中没有任何内容.

The textarea appears in html but it has no display: block in the css. It has nothing in the css, to be clear.

当我自己在CSS中添加 display:block 时，它只是被chrome/firefox剥离了.

When I add a display:block in the css myself, it simply stripped by chrome/firefox.

仅当我从单独的类创建表单时才会发生此问题，而不是在控制器的函数中创建表单时才会发生.

The problem only happens when I create the form from a separate Class, not when I create it in controller's function.

这是我的代码:

AdController.php

AdController.php

<?php

namespace App\Controller;


use App\Entity\Ad;
use App\Form\AdType;
use App\Repository\AdRepository;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;

class AdController extends AbstractController
{


    /**
     * Create ad
     *
     * @Route("/ads/new", name="ads_create")
     * 
     * @return Response
     */
    public function create(){

         $ad = new Ad();

         $form = $this->createForm(AdType::class, $ad);


        return $this->render('ad/new.html.twig', [
            'form' => $form->createView()
        ]);
    }


}

AdType.php

AdType.php

<?php

namespace App\Form;

use App\Entity\Ad;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Component\Form\Extension\Core\Type\TextareaType;

class AdType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('title')
            ->add('slug')
            ->add('price')
            ->add('introduction')
            ->add('content', TextareaType::class, [
                'attr' => array('cols' => '5', 'rows' => '5')])
            ->add('coverImage')
            ->add('rooms')
        ;
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            'data_class' => Ad::class,
        ]);
    }
}

还有树枝:

{% extends 'base.html.twig' %}
{% form_theme form 'bootstrap_4_layout.html.twig' %}

{% block title %}Create ad{% endblock %}

{% block body %}
    <div class="container">
        <h1>lorem ipsum</h1>


        {{form_start(form)}}

            {{ form(form) }}



        {{form_end(form)}}

    </div>
{% endblock %}

我尝试了很多事情，但是我仍然不知道如何解决这个问题.有人对此有想法吗?

I tried a lot of things but I still don't understand how to solve this problem. Do someone have an idea about it ?

提前谢谢！

推荐答案

我遇到了同样的问题

解决方案是要禁用AdBlock

SOLUTION was to disable AdBlock

Adblock隐藏了文本区域，因为它认为这是一个广告(您的实体名称以"ad"前缀开头)

Adblock hid the textarea beacause it thought it was an ad (your entities name begin with the "ad" prefix)
