tp5自定义分页

By Wu Yudong on June 23, 2019

第一步:创建文件Page.php,将其放到extend\page,这里也可以自己决定,命名空间对了就行

代码如下:

<?php

// 2018/10/23 by Wu Yudong
namespace page;
use think\Paginator;
class Page extends Paginator 
{
	// 首页
	protected function home() {
		if ($this->currentPage () > 1) {
			
			return "<a href='" . $this->url ( 1 ) . "' title='首页'>首页</a>";
		} else {
			
			return "<p>首页</p>";
		}
	}
	
	// 上一页
	protected function prev() {
		if ($this->currentPage () > 1) {
			
			return "<a href='" . $this->url ( $this->currentPage - 1 ) . "' title='上一页'>上一页</a>";
		} else {
			
			return "<p>上一页</p>";
		}
	}
	
	// 下一页
	protected function next() {
		if ($this->hasMore) {
			
			return "<a href='" . $this->url ( $this->currentPage + 1 ) . "' title='下一页'>下一页</a>";
		} else {
			
			return "<p>下一页</p>";
		}
	}
	
	// 尾页
	protected function last() {
		if ($this->hasMore) {
			
			return "<a href='" . $this->url ( $this->lastPage ) . "' title='尾页'>尾页</a>";
		} else {
			
			return "<p>尾页</p>";
		}
	}
	
	// 统计信息
	protected function info() {
		return "<p class='pageRemark'>共<b>" . $this->lastPage . 

		"</b>页<b>" . $this->total . "</b>条数据</p>";
	}
	
	/**

	 */
	protected function getLinks() 
	{
		$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) {

		}
		$html = '';

	}

                color:#808080;
                font-size:12px;
                line-height:24px;
            }
            .pagination a:hover{
                color:#077ee3;
                background: white;
                border:1px #077ee3 solid;
            }
            .pagination a.cur{
                border:none;
                background:#077ee3;
                color:#fff;
            }
            .pagination p{
                float:left;
                padding:2px 12px;
                font-size:12px;
                height:24px;
                line-height:24px;
                color:#bbb;
                border:1px #ccc solid;
                background:#fcfcfc;
                margin-right:8px;
            }
            .pagination p.pageRemark{
                border-style:none;
                background:none;
                margin-right:0px;
                padding:4px 0px;
                color:#666;
            }

            .pagination p.pageRemark b{
                color:red;
            }

            .pagination p.pageEllipsis{
                border-style:none;
                background:none;
                padding:4px 0px;
                color:#808080;
            }
            .dates li {font-size: 14px;margin:20px 0}
            .dates li span{float:right}
        </style>';
	}
}

第二步:修改配置文件

在config文件夹下新建paginate.php文件,添加如下代码:

<?php
//分页配置
return [
	
	'type'      => 'page\Page',//分页类
	'var_page'  => 'page',
	'list_rows' => 3,
	
];
