Laravel 4 pagination count
提问by erm_durr
I have set a pagination in my specific view/site, and it works.
我在我的特定视图/站点中设置了一个分页，并且它有效。
The problem is I have a php counter:
问题是我有一个 php 计数器：
<?php $count = 0;?>
@foreach ($players as $player)
<?php $count++;?>
<tr>
<td>{{ $count }}. </td>
and whenever I switch pages, it starts from 1.
每当我切换页面时，它都是从 1 开始的。
How could I change that?
我怎么能改变呢？

In order to achieve that, you need to initialize the value of counter:
为了实现这一点，您需要初始化计数器的值：
<?php $count = (($current_page_number - 1) * $items_per_page) + 1; ?>
NoticeI'm first subtracting 1from current page, so the first page number is 0. Then I'm adding 1to the total result, so your first item starts with 1, instead of 0.
请注意，我首先1从当前页面中减去，因此第一个页码是0. 然后我将添加1到总结果中，因此您的第一个项目以1, 而不是0.
Laravel Paginator provides a handy shortcut for that:
Laravel 分页器为此提供了一个方便的快捷方式：
<?php $count = $players->getFrom() + 1; ?>
@foreach ($players as $player)
...
There are a few others that you can use as you like:
还有其他一些您可以随意使用：
$players->getCurrentPage();
$players->getLastPage();
$players->getPerPage();
$players->getTotal();
$players->getFrom();
$players->getTo();

<?php echo "Displaying ".$data->getFrom() ." - ".$data->getTo(). " of ".number_format($data->getTotal())." result(s)"; ?>
回答by Ifan Iqbal
We only need method getFromfrom Paginator instance to be able counting from the first item in the page.
我们只需要getFrom来自 Paginator 实例的方法就可以从页面中的第一项开始计数。
<?php $count = $players->getFrom(); ?>
@foreach ($players as $player)
<tr>
<td>{{ $count++ }}. </td>
</tr>
@endforeach

You don't need a counter.
你不需要柜台。
After you get the key that starts from 0, you need to add 1. After that you add the current page-1 * items per page
得到从0开始的key后，需要加1，然后加当前页-1 * 每页的items
You can do it like this:
你可以这样做：
@foreach ($players as $key => $player)
<tr>
<td>{{ $key+1+(($players->getCurrentPage()-1)*$players->getPerPage()) }}</td>
</tr>
@endforeach

<?php $count++; ?>
@if($players->getCurrentPage() > 1)
{{ ((($players->getCurrentPage() - 1)* $players->getPerPage()) + $count)}}
@else
{{$count}}
@endif
