限制 Laravel 分页显示的链接数量

Limit amount of links shown with Laravel pagination(限制 Laravel 分页显示的链接数量)

问题描述

有什么简单的方法可以限制 Laravel 分页显示的链接数量?

Any easy way to limit how many links are shown with Laravels pagination?

目前最多显示 13 个链接(上一页，1 2 3 4 5 7 8 .. 78 79 下一页)

Currently it shows 13 links at most (Prev, 1 2 3 4 5 7 8 .. 78 79 next)

然而，这对于移动设备来说太多了，变成了两行导航......有没有办法将链接设置为例如只显示 10 个?

This however is too much for mobile devices and becomes a two line navigation... is there any way to set the links to e.g. only show 10?

我搞乱了分页演示者，但实际上似乎没有任何效果.

I have messed around with the pagination presenter but nothing actually seemed to work.

谢谢

推荐答案

定义自定义演示者的旧方法不适用于 Laravel 5.3+，显示的链接数量似乎是在 中硬编码的Illuminate/Pagination/UrlWindow::make() 的 $onEachSide 参数:

The old way of defining a custom presenter doesn't work with Laravel 5.3+, the number of links shown seems to be hard-coded in the $onEachSide parameter of Illuminate/Pagination/UrlWindow::make():

public static function make(PaginatorContract $paginator, $onEachSide = 3)

我最终只是编写了自己的 render() 函数，从 LengthAwarePaginator

I ended up just writing my own render() function, stealing some code from LengthAwarePaginator

/**
     * Stole come code from LengthAwarePaginator::render() and ::elements() to allow for a smaller UrlWindow
     *
     * @param LengthAwarePaginator $paginator
     * @param int $onEachSide
     * @return string
     */
    public static function render(LengthAwarePaginator $paginator, $onEachSide = 2)
    {
        $window = UrlWindow::make($paginator, $onEachSide);

        $elements = array_filter([
            $window['first'],
            is_array($window['slider']) ? '...' : null,
            $window['slider'],
            is_array($window['last']) ? '...' : null,
            $window['last'],
        ]);

        return LengthAwarePaginator::viewFactory()->make(LengthAwarePaginator::$defaultView, [
            'paginator' => $paginator,
            'elements' => $elements,
        ])->render();
    }
}

我们使用 Twig，所以我将其注册为 Twig 过滤器，我想可以为 Blade 做类似的事情.

We use Twig, so I registered this as a Twig filter, I imagine something similar could be done for Blade.
