在Twig中的实体打印循环(Entity print loop for in Twig)

在Twig中的实体打印循环(Entity print loop for in Twig)

我正在尝试制作动态树枝模板来打印具有不同字段数的实体列表。 重点是我无法打印$lligues所有列。

我的控制器看起来像这样：

/** * @Route("/llistarlliga",name="llistar_lliga") */ public function llistarLliga(){ $repository = $this->getDoctrine()->getRepository('AppBundle:Lliga'); $camps = array('Nom','Nº equips','Accions'); $lligues = $repository->findAll(); return $this->render('templates/list.html.twig', array('camps' => $camps, 'lligues' => $lligues, 'title' => 'Llistat de lligues')); }

树枝模板：

{# app/Resources/views/forms/lista.html.twig #} {% extends "templates/home.html.twig" %} {% block title %} {{title}} {% endblock %} {% block body %} <table> <thead> {% for i in 0..camps|length-1 %} <th>{{camps[i]}}</th> {% endfor %} </thead> <tbody> {% for lliga in lligues %} <tr> <td>{{lliga.nom}}</td> <td>{{lliga.numequips}}</td> <td> <a href="{{ path('borrar_lliga', {'nom' : lliga.nom}) }}"><img src="{{ asset('images/bin.png') }}" /></a> <a href="{{ path('modificar_lliga', {'nom' : lliga.nom}) }}"><img src="{{ asset('images/edit.png') }}" /></a> </td> </tr> {% endfor %} </tbody> </table> {% endblock %}

因此，我想更改第二个循环（对于llig中的lliga）使其动态化，因此如果它有更多字段或更少，它也会打印它们。

谢谢大家！

I'm trying to make a dynamic twig template to print lists of Entities with different number of fields. The whole point is that I can't print all the columns of $lligues.

My controller looks like this:

/** * @Route("/llistarlliga",name="llistar_lliga") */ public function llistarLliga(){ $repository = $this->getDoctrine()->getRepository('AppBundle:Lliga'); $camps = array('Nom','Nº equips','Accions'); $lligues = $repository->findAll(); return $this->render('templates/list.html.twig', array('camps' => $camps, 'lligues' => $lligues, 'title' => 'Llistat de lligues')); }

Twig template:

{# app/Resources/views/forms/lista.html.twig #} {% extends "templates/home.html.twig" %} {% block title %} {{title}} {% endblock %} {% block body %} <table> <thead> {% for i in 0..camps|length-1 %} <th>{{camps[i]}}</th> {% endfor %} </thead> <tbody> {% for lliga in lligues %} <tr> <td>{{lliga.nom}}</td> <td>{{lliga.numequips}}</td> <td> <a href="{{ path('borrar_lliga', {'nom' : lliga.nom}) }}"><img src="{{ asset('images/bin.png') }}" /></a> <a href="{{ path('modificar_lliga', {'nom' : lliga.nom}) }}"><img src="{{ asset('images/edit.png') }}" /></a> </td> </tr> {% endfor %} </tbody> </table> {% endblock %}

So, I would like to change the second loop (for lliga in lligues) to make it dynamic, so if it has more fields or less, it prints them too.

Thanks to everyone!

您可以创建一个cast_to_array过滤器cast_to_array 。

首先，您需要创建自定义过滤器。 像这样的东西：

namespace AppBundle\Twig; class ArrayExtension extends \Twig_Extension { /** * @inheritDoc */ public function getFilters() { return array( new \Twig_SimpleFilter('cast_to_array', array($this, 'castToArray')) ); } public function castToArray($stdClassObject) { $response = array(); foreach ($stdClassObject as $key => $value) { $response[] = array($key, $value); } return $response; } /** * Returns the name of the extension. * * @return string The extension name */ public function getName() { return 'array_extension'; } }

并将其添加到您的app\config\services.yml ：

services: app.twig_extension: class: AppBundle\Twig\ArrayExtension public: false tags: - { name: twig.extension }

最后，您需要在Twig模板中使用自定义过滤器：

{# app/Resources/views/forms/lista.html.twig #}
{% extends "templates/home.html.twig" %}
{% block title %}
    {{title}}
{% endblock %}
{% block body %}  
    <table>
        <thead>
            {% for i in 0..camps|length-1 %}
                <th>{{camps[i]}}</th>
            {% endfor %}
        </thead>
        <tbody>
            {% for lliga in lligues %}
                <tr>

                    {% for key, value in lliga|cast_to_array %}
                        <td>{{ value }}</td>
                    {% endfor %}

                    <td>
                        <a href="{{ path('borrar_lliga', {'nom' : lliga.nom }) }}"><img src="{{ asset('images/bin.png') }}" /></a>
                        <a href="{{ path('modificar_lliga', {'nom' : lliga.nom }) }}"><img src="{{ asset('images/edit.png') }}" /></a>
                    </td>
                </tr>
            {% endfor %}
        </tbody>
    </table>
{% endblock %}
 
 我相信这可以解决问题。 
You can create a twig filter cast_to_array.
 
First you need to create the custom filter. Something like this: 
 
namespace AppBundle\Twig;


class ArrayExtension extends \Twig_Extension
{
    /**
     * @inheritDoc
     */
    public function getFilters()
    {
        return array(
            new \Twig_SimpleFilter('cast_to_array', array($this, 'castToArray'))
        );
    }

    public function castToArray($stdClassObject) {
        $response = array();
        foreach ($stdClassObject as $key => $value) {
            $response[] = array($key, $value);
        }
        return $response;
    }


    /**
     * Returns the name of the extension.
     *
     * @return string The extension name
     */
    public function getName()
    {
        return 'array_extension';
    }
}
 
And add it to your app\config\services.yml: 
 
services:
app.twig_extension:
    class: AppBundle\Twig\ArrayExtension
    public: false
    tags:
        - { name: twig.extension }
 
Finally, you case use your custom filter in your Twig templates:
 
{# app/Resources/views/forms/lista.html.twig #}
{% extends "templates/home.html.twig" %}
{% block title %}
    {{title}}
{% endblock %}
{% block body %}  
    <table>
        <thead>
            {% for i in 0..camps|length-1 %}
                <th>{{camps[i]}}</th>
            {% endfor %}
        </thead>
        <tbody>
            {% for lliga in lligues %}
                <tr>

                    {% for key, value in lliga|cast_to_array %}
                        <td>{{ value }}</td>
                    {% endfor %}

                    <td>
                        <a href="{{ path('borrar_lliga', {'nom' : lliga.nom }) }}"><img src="{{ asset('images/bin.png') }}" /></a>
                        <a href="{{ path('modificar_lliga', {'nom' : lliga.nom }) }}"><img src="{{ asset('images/edit.png') }}" /></a>
                    </td>
                </tr>
            {% endfor %}
        </tbody>
    </table>
{% endblock %}
