如何解决如何粘贴多个图像 Symfony
我有两个实体投资组合和图像关系ManyToOne，照片在数据库中我想检索它们，我得到了这个结果。 Click Here
我想在作品集列表中显示照片，并能够在项目详细信息页面上显示照片轮播。转到投资组合部分并单击链接（更多详细信息）。 https://bootstrapmade.com/demo/Arsha/ 但我有这个错误 Click Here
谢谢。

Twig 投资组合列表 我找到了部分问题的解决方案，我可以检索项目列表的照片，但在详细信息页面中我没有错误但图像没有显示。
<div class="row portfolio-container">
{% for portfolio in portfolios %}
<div class="col-lg-4 col-md-6 portfolio-item filter-app">
<div class="portfolio-wrap">
<img src="{{asset('assets/img/portfolio/' ~ portfolio.images[0].nom)}}" class="img-fluid" alt="">
<div class="portfolio-info">
<h4>{{ portfolio.titre }}</h4>
{% for categorie in portfolio.categories %}
<p>{{ categorie.nom }}</p>
{% endfor %}
<div class="portfolio-links">
<a href="{{asset('assets/img/portfolio/portfolio-1.jpg')}}" data-gallery="portfolioGallery"
class="portfolio-lightbox" title="App 1"><i class="bx bx-plus"></i></a>
<a href="{{ path('portfolio_detail',{'slug': portfolio.slug}) }}" title="Plus Details"><i class="bx bx-link"></i></a>
</div>
</div>
</div>
</div>
{% endfor %}
Twig 组合详细信息
<div class="col-lg-8">
<div class="portfolio-details-slider swiper-container">
<div class="swiper-wrapper align-items-center">
{% for images in portfolio.images %}
<div class="swiper-slide">
<img src="{{asset('assets/img/portfolio/' ~ images.nom)}}" alt="">
</div>
{% endfor %}
</div>
<div class="swiper-pagination"></div>
</div>
</div>
控制器
<?php
namespace App\Controller;
use App\Entity\Portfolio;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
class AccueilController extends AbstractController
{
/**
* @Route("/",name="accueil")
*/
public function index(): Response
{
//lister portfolio
$portfolios = $this->getDoctrine()->getRepository(Portfolio::class)->findBy(
[],['created_at' => 'desc']
);
return $this->render('accueil/index.html.twig',[
'portfolios' => $portfolios,]);
}
/**
* @Route("/portfolio/{slug}",name="portfolio_detail",methods={"GET"})
*/
public function detail($slug): Response
{
// On récupère l'article correspondant au slug
$portfolio = $this->getDoctrine()->getRepository(Portfolio::class)->findOneBy(['slug' => $slug]);
return $this->render('accueil/detail.html.twig',[
'portfolio' => $portfolio,]);
}
}
解决方法
我的代码有效，希望可以帮助到其他人。
