ThinkPHP6自訂分頁

ThinkPHP6.0為我們預先定義了paginate分頁類，幫助我們快速分頁，但是ThinkPHP6提供的分頁的樣式並不是我們想要的，需要我們自己擴展分頁類，看看具體如何實現吧！

首先我們去複製一份官方的寫好的分頁類，並在此基礎上進行修改，具體的路徑在vendor/topthink/think-orm/src/paginator/driver/Bootstrap.php，然後在app/common/Bootstrap.php貼上。

修改app/provider.php服務提供者，修改預設的分頁驅動為我們的驅動。

<?php
use app\ExceptionHandle;
use app\Request;
// 容器Provider定义文件
return [
    &#39;think\Request&#39;          => Request::class,
    &#39;think\exception\Handle&#39; => ExceptionHandle::class,
    &#39;think\Paginator&#39;    =>    &#39;app\common\Bootstrap&#39;
];

閱讀app/common/Bootstrap.php程式碼，在此基礎上修改。以下是官方提供的分頁代碼vendor/topthink/think-orm/src/paginator/driver/Bootstrap.php

        }
        return $this->getAvailablePageWrapper($url, $page);
    }
}

例如簡單修改上一頁下一頁為中文漢字，修改以下地方。
 

/**
     * 上一页按钮
     * @param string $text
     * @return string
     */
    protected function getPreviousButton(string $text = "上一页"): string
    {
        if ($this->currentPage() <= 1) {
            return $this->getDisabledTextWrapper($text);
        }
        $url = $this->url(
            $this->currentPage() - 1
        );
        return $this->getPageLinkWrapper($url, $text);
    }
    /**
     * 下一页按钮
     * @param string $text
     * @return string
     */
    protected function getNextButton(string $text = &#39;下一页&#39;): string
    {
        if (!$this->hasMore) {
            return $this->getDisabledTextWrapper($text);
        }
        $url = $this->url($this->currentPage() + 1);
        return $this->getPageLinkWrapper($url, $text);
    }

然後依照自己的業務需求進行修改！
