yii2 detailview条件行类 [英] yii2 detailview conditional row class

问题描述

我想根据条件更改detailview中单个属性的类：

I would like to change class for one single attribute in detailview, based on a condition:

如果我不想让它成为有条件的，它将是像这样工作：

If I wouldn't want to make it conditional, it would be working like so:

[
    'attribute' => 'ungueltig',
    'format' => 'boolean',
    'contentOptions' => [
        'class' => 'danger',
        ]
],

我希望这个改变有条件的，我已经尝试了很多不同的方式，例如：

I want this one to change to conditional, and I have tried a lot of different ways, e.g.:

[
    'attribute' => 'ungueltig',
    'format' => 'boolean',
    'contentOptions' => function ($model) {
        if ($model->ungueltig == 1) {
            return ['class' => 'danger'];
        } else {
            return '';
        }
    },
],

（我想这是最合乎逻辑的解决方案，但没有任何反应，因此页面加载正常但属性没有类危险，没有错误消息）

(I would think this is the most logical solution, but nothing happens, so page is loading fine but without class danger at the attribute, no error message)

或

[
    'attribute' => 'ungueltig',
    'format' => 'boolean',
    'contentOptions' => ['class' => function ($model) {
        if ($model->ungueltig == 1) {
            return 'danger';
        } else {
            return '';
        }
    },]
],

=错误讯息： htmlspecialchars（）期望参数1为字符串，给定对象

所以我没有任何线索，我甚至找不到任何帮助网络。你能指点我正确的方向吗？非常感谢！

so I have no clue and I don't even find any help on the web. Can you please point me to the right direction? Many thanks!

推荐答案

您应该尝试：

'contentOptions' => [
    'class' => ($model->ungueltig == 1) ? 'danger' : '',
],

DetailView 只显示一个模型，这里不需要任何函数。

DetailView display only one model, you don't need any function here.
