ThinkPHP6.0使用自定义分页类 重写paginate页码

作者: 思议岁月 | 来源:发表于2019-12-10 17:03 被阅读0次

    ThinkPHP6.0给我们预定义了paginate分页类,帮助我们快速分页,但是ThinkPHP6提供的分页的样式并不是我们想要的,需要我们自己扩展分页类,看看具体如何实现吧!

    1. 首先我们去复制一份官方的写好的分页类,并在此基础上进行修改,具体的路径在vendor/topthink/think-orm/src/paginator/driver/Bootstrap.php,然后在app/common/Bootstrap.php粘贴。
    2. 修改app/provider.php服务提供者,修改默认的分页驱动为我们的驱动。
    <?php
    use app\ExceptionHandle;
    use app\Request;
    
    // 容器Provider定义文件
    return [
        'think\Request'          => Request::class,
        'think\exception\Handle' => ExceptionHandle::class,
        'think\Paginator'    =>    'app\common\Bootstrap'
    ];
    
    1. 阅读app/common/Bootstrap.php代码,在此基础上修改。以下是官方提供的分页代码vendor/topthink/think-orm/src/paginator/driver/Bootstrap.php

        /**
         * 批量生成页码按钮.

        {

                $html .= $this->getPageLinkWrapper($url, $page);
            }
    
            return $html;
        }
    
        /**
         * 生成普通页码按钮
         *
         * @param  string $url

         * @return string
         */
        protected function getPageLinkWrapper(string $url, string $page): string
        {
            if ($this->currentPage() == $page) {
                return $this->getActivePageWrapper($page);
            }
    
            return $this->getAvailablePageWrapper($url, $page);
        }
    }
    
    

    例如简单修改上一页下一页为中文汉字,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 $text = '下一页'): string
        {
            if (!$this->hasMore) {
                return $this->getDisabledTextWrapper($text);
            }
    
            $url = $this->url($this->currentPage() + 1);
    
            return $this->getPageLinkWrapper($url, $text);
        }
    

    然后根据自己的业务需求进行修改!
