一、因爲有複雜的數據統計,需要組數組,這時候使用tp6的分頁會有問題,於是改爲數組分頁的方式,將以前tp3的分頁拿過來改了一下,話不多說上代碼,引入tp3分頁源代碼,爲了和tp6的區別不會太明顯,修改了源代碼,放入tp6 \vendor\topthink\framework\src\think 下:
修改詳情:
1、樣式(ul li)
2、C方法改爲 config
3、U方法改爲 url
4、ACTION_NAME改爲:

$request ->action

二、具體使用
//頭部記得引入
use think\Page;
//數組分頁
//傳入分頁值
$p = empty($_GET['page']) ? 1 : $_GET['page'];
//每頁顯示條數
$num = empty(Request::param('num')) ? $this->num : Request::param('num');
//當前獲取的數據 我這裏的數據數組是 $info 是一個二位數組
$count = count($info);
//總數據條數 每頁數據條數 需要帶的參數(比如查詢的值)
$page = new Page($count,$num,['num'=>$num,'startTime'=>'','endTime'=>'','province'=>$province]);//10爲每頁顯示的條數,$page爲傳過來的頁碼
$info = array_slice($info,($p-1)*$num,$num); //重組數組 / ($page-1)*$num 計算每頁的數據從第幾條開始
return view('totalData',[
'p' => $p, //顯示第幾頁
'num' => $num,
'page' => ($count < $num) ? '' : $page->show(), // 獲取分頁顯示注意判斷當前數據是否夠分頁
'pageshow' => pageShow($count,$num,$p), //總記錄數,每頁顯示條數
'info' => $info
]);
//前端模板輸出
/* {$page|raw} */
