提供计数变量时，Laravel 4 从 foreach 循环中添加数字? [英] Laravel 4 adding numbers from foreach loop when count variable is supplied?

问题描述

我将数组 $cats 传递给我的 laravel 模板视图.它是来自数据库事务的多维数组，包含类别数据.所以它将包含如下数据:

I am passing the array $cats to my laravel template view. It is a multidimensional array from a database transaction, containing category data. So it would contain data like:

$cat[0]['id'] = 1;
$cat[0]['name'] = 'First Category';

等等.在我的刀片模板中，我有以下代码:

And so on. In my blade template I have the following code:

            {{ $i=0 }}
            @foreach($cats as $cat)

                    {{ $cat['name'] }}<br />

                {{ $i++ }}

            @endforeach

输出:

0 First Category
1 Second Category
2 Third Category

注意类别名称前面的数字.他们来自哪里?这是一些聪明的 Laravel 技巧吗?似乎当您包含计数器变量时，它们会自动添加.我在任何地方都找不到任何提及它，我不想要它们！我该如何摆脱它们?

Notice the numbers preceding the category name. Where are they coming from? Is this some clever Laravel trick? It seems that when you include a counter variable, they are automatically added. I can't find any mention of it anywhere, and I don't want them! How do I get rid of them?

谢谢.

推荐答案

你只需要使用纯php翻译即可:

You just need to use the plain php translation:

@foreach ($collection as $index => $element)
   {{$index}} - {{$element['name']}}
@endforeach

注意$index将从0开始，所以应该是{{ $index+1 }}

Note the $index will start from 0, So it should be {{ $index+1 }}
