重点＆QUOT;路径＆QUOT;与钥匙＆QUOT阵列;＆QUOT;而转储说，它不存在 [英] Key "path" for array with keys "" does not exist while dump says it does

问题描述

我目前的CMS工作使用的Symfony2作为底层框架和小枝作为模板引擎。

I'm currently working on a cms using symfony2 as the underlying framework and twig as the template engine.

我的问题是这样的：

虽然这

{% for image in images %}
    {{ dump(image.path is defined) }}
{% endfor %}

每个元素的数组中返回true，...

returns true for each element in the array,...

...但是这一次

{% for image in images %}
    {{ image.path}}
{% endfor %}

抛出exeption。

throws an exeption.

的键道与按键，数组不存在的

图像阵列的树枝转储返回这样的：

A twig-dump of the images-array returns this:

array(2) {
    [0]=> object(stdClass)#2759 (9) {
        ["id"]=> string(5) "17795"
        ["typ"]=> string(3) "jpg"
        ["path"]=> string(10) "Tulips.jpg"
    }
    [1]=> object(stdClass)#2874 (9) {
        ["id"]=> string(5) "17796"
        ["typ"]=> string(3) "jpg"
        ["path"]=> string(14) "Hydrangeas.jpg"
    }
}

这似乎是悖论给我，我真的不明白这一点。
有一个人的想法？我会非常感激，最后期限即将到来...：/

This seems to be paradox to me and i really don't understand this. Has someone an Idea? I would be very thankful, deadlines are coming... :/

推荐答案

我觉得你创建多维数组。尝试使用图像中的树枝模板foreach循环还

I think u created multidimensional array. Try foreach loop in twig template for image also

{% for image in images %}
    {% for i in image %}
       {{ i.datei }}
    {% endfor %}
{% endfor %}
