Question

我从外部源检索我的数据，因此必须手动构建分页。然而，它只输出所有结果，起初我认为这可能是因为我的数组内部有对象，但在两种情况下都会出现。我做错了什么？

<?php

class MainController extends BaseController {
    // Base controller specifies layout
    // protected $layout = 'master';
    public function index()
    {
        $this->layout->title = 'testing';
        $this->layout->main = View::make('testing');

        $objArray = array();
        $entry = new \stdClass();
        $entry->title = "testing";
        $objArray[] = $entry;
        $objArray[] = $entry;
        $objArray[] = $entry;
        $objArray[] = $entry;

        $this->layout->main->paginated = Paginator::make($objArray, count($objArray), '2');
        // var_dump($paginated->count()); // returns 4

        $array = array(
            array('title' => 'test'),
            array('title' => 'test'),
            array('title' => 'test'),
            array('title' => 'test')
        );

        $this->layout->main->arrayPaginated = Paginator::make($array, count($array), '2');
        // var_dump($arrayPaginated->count()); // returns 4
    }

}

查看档案

## view/testing

@foreach($paginated as $entry)
    {{$entry->title}}
@endforeach
{{$paginated->links()}} //outputs "testing" four times

@foreach($arrayPaginated as $entry)
    {{$entry['title']}}
@endforeach
{{$arrayPaginated->links()}} //outputs "test" four times

正如你在评论中指出的那样，你必须自己切片，有一点我无法理解的是第三个参数的用户是什么“每页的项目数”如果你必须限制的话将条目传递给分页器之前的条目。

$objArray = array();
for($i = 0; $i < 4; $i++) {
    $entry = new \stdClass();
    $entry->title = "test {$i}";
    $objArray[] = $entry;
}

$perPage = 2;
$page = Input::get('page', 1); // Set default to 1 if nothing is passed
// ($page - 1) so that when page is 1 you are targetting the start of the array

$pagedData = array_slice($objArray, ($page - 1) * $perPage, $perPage);
$this->layout->main->paginated = Paginator::make($pagedData, count($objArray), $perPage);

视图文件中没有任何变化。
