笔记:ThinkPHP默认样式替换为LayUI

基于对ThinkPHP的了解程度不够,在实际运用中发现使用ThinkPHP的分页,即

{$list->render()}

默认出来的样式是错误的,想了下原因,可能是没有引用TP默认CSS的原因吧,其实具体原因我并没有去找,我只想用上LayUI。

网上找了下资料,自己整理如下:

在extend下建立目录,目录名随意,根据命名空间作对应修改即可,这里我以page为例,并在目录下建立Page.php

extend/page/Page.php

代码如下:

<?php 
namespace page;
 
use think\Paginator;
 
class Page extends Paginator
{
    protected $uri;
    /**
     * 上一页按钮
     * @param string $text
     * @return string
     */
    protected function getPreviousButton($text = "上一页")
    {
 
        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 $text
     * @return string
     */
    protected function getNextButton($text = '下一页')
    {
        if (!$this->hasMore) {
            return $this->getDisabledTextWrapper($text);
        }
 
        $url = $this->url($this->currentPage() + 1);
 
        return $this->getPageLinkWrapper($url, $text);
    }
 
    /**
     * 页码按钮
     * @return string
     */

    {
        if ($this->simple)
            return '';
 
        $block = [
            'first'  => null,
            'slider' => null,
            'last'   => null
        ];
 
        $side   = 3;
        $window = $side * 2;
 
        if ($this->lastPage < $window + 6) {
            $block['first'] = $this->getUrlRange(1, $this->lastPage);
        } elseif ($this->currentPage <= $window) {
            $block['first'] = $this->getUrlRange(1, $window + 2);
            $block['last']  = $this->getUrlRange($this->lastPage - 1, $this->lastPage);

            $block['last']  = $this->getUrlRange($this->lastPage - ($window + 2), $this->lastPage);
        } else {

同时对config.php进行修改,找到下方内容进行对应修改即可

//分页配置
    'paginate'               => [
        /* 'type'      => 'bootstrap', */
		'type'      => 'page\Page',
        'var_page'  => 'page',
        'list_rows' => 15,
    ],
