ThinkPHP6自定义分页

ThinkPHP  /  管理员 发布于 8年前   658

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！

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。

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。

<?phpuse 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'];

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

'">' . $page . '</a></li>';    }    /**     * 生成一个禁用的按钮     *     * @param  string $text     * @return string     */    protected function getDisabledTextWrapper(string $text): string    {        return '<li class="disabled"><span>' . $text . '</span></li>';    }    /**     * 生成一个激活的按钮     *     * @param  string $text     * @return string     */    protected function getActivePageWrapper(string $text): string    {        return '<li class="active"><span>' . $text . '</span></li>';    }    /**     * 生成省略号按钮     *     * @return string     */    protected function getDots(): string    {        return $this->getDisabledTextWrapper('...');    }    /**     * 批量生成页码按钮.     *     * @param  array $urls     * @return string     */    protected function getUrlLinks(array $urls): string    {        $html = '';        foreach ($urls as $page => $url) {            $html .= $this->getPageLinkWrapper($url, $page);        }        return $html;    }    /**     * 生成普通页码按钮     *     * @param  string $url     * @param  string    $page     * @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！
