我正在尝试处理我的控制器中的非现有变量,如果数据库为空将返回一个没有任何变量的视图:
if(!$votes->findOneById(1) || !$images->findOneById(1)){
return $this->render('admin/stats_and_images.html.twig');
}
return $this->render('admin/stats_and_images.html.twig', [
'images' => $images->countVotesForAllImages(),
'image_podium' => $images->getTopNImages(3),
'form' => $form->createView(),
'votesToday' => $votes->votesToday(),
'votesMonth' => $votes->votesMonth(),
'votesTotal' => $votes->votesTotal()
]);
在我看来,我正试图处理缺乏这样的变量:
{% if (votesTotal[0][1] is defined) and (votesToday[0][1] is defined) and (votesMonth[0][1] is defined) %}
<div class="col-md-6">
<h4 class="sub-section--header">Liczba Oddanych Głosów:</h4>
<hr>
<p>
<div class="col-sm-6">
Dzisiaj:
<span class="text-info large-num">{{ votesToday[0][1] }}</span>
</div>
<div class="col-sm-6">
Ten miesiąc:
<span class="text-info large-num">{{ votesMonth[0][1] }}</span>
</div>
</p>
<p>
<strong>Głosów ogółem: </strong><span class="text-info large-num">{{ votesTotal[0][1] }}</span>
</p>
</div>
<div class="col-md-6">
<h4 class="sub-section--header">Wygrywające zdjęcia:</h4>
<p class="text-muted">Ten miesiąc</p>
<hr>
<div class="row text-center">
<div class="col-md-4">
<a
href="{{ asset("uploads/"~image_podium[0][0].fileName) }}"
target="blank">

class="site-thumbnail"
title="{{image_podium[0][0].title}} - {{image_podium[0][0].author}}">
</a>
<p><strong>Głosów: {{image_podium[0]['votes']}}</strong></p>
</div>
<div class="col-md-4">

class="site-thumbnail"
title="{{image_podium[1][0].title}} - {{image_podium[1][0].author}}">
</a>
<p>Głosów: {{image_podium[1]['votes']}}</p>
</div>
<div class="col-md-4">
<a
href="{{ asset("uploads/"~image_podium[2][0].fileName) }}"
target="blank">
<img

class="site-thumbnail"
title="{{image_podium[2][0].title}} - {{image_podium[2][0].author}}">
</a>
<p>Głosów: {{image_podium[2]['votes']}}</p>
</div>
</div>
</div>
{% else %}
<h2 class="text-danger text-center">
No votes at the moment :)
</h2>
{% endif %}
但是,尽管要定义所有三个领域的严格要求,我还是得到了这个:
变量“votesToday”不存在。
并指向视图的<span class="text-info large-num">{{ votesToday[0][1] }}</span>
部分。
为什么会这样?如何避免?
答案 0 :(得分:0)
将$ votes发送给twig并使用{{dump(votes)}}
进行检查如果是学说实体,请检查你的吸气剂。也许是$ votes-&gt; getVotesToday()
