ThinkPHP6 custom paging

ThinkPHP6.0 predefines the paginate paging class for us to help us quickly paginate. However, the paging style provided by ThinkPHP6 is not what we want. We need to extend the paging class ourselves and see how to implement it!

First we copy an official paging class and modify it on this basis. The specific path is vendor/topthink/think-orm/src/paginator/driver/Bootstrap.php. Then paste it in app/common/Bootstrap.php.

Modify the app/provider.php service provider and modify the default paging driver to be our driver.

<?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;
];

Read the app/common/Bootstrap.php code and modify it based on this. The following is the officially provided paging code vendor/topthink/think-orm/src/paginator/driver/Bootstrap.php

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

For example, simply modify the previous page and the next page to Chinese characters, modify the following places.

/**
     * 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);
    }

Then modify it according to your business needs!
