我看見(jiàn)只是幾個(gè)函數(shù)用法錯(cuò)誤而已
版本高了
我知道版本高了，現(xiàn)在就是要在這個(gè)環(huán)境下解決問(wèn)題。因?yàn)楸仨氂眠@個(gè)高版本環(huán)境，因?yàn)檫€有一套程序很消耗mysql，mysql8性能很好
要不把數(shù)據(jù)遷移到迅睿cms，迅睿cms支持更高的版本
不遷移，已經(jīng)三年了，數(shù)據(jù)會(huì)錯(cuò)亂的，而且我改過(guò)很多
全論壇每一個(gè)人知道，我今天上午自己花了2小時(shí)解決了。
答案公布一下，希望以后其他人用得到。任何老版本可以直接升級(jí)mysql8.0，以及php為7.4版本。
修改三個(gè)文件：如下
①
1：diy/dayrui/models/Category_model.php 108行
2：diy/dayrui/models/Category_model.php 159行
3：diy/dayrui/models/Category_model.php 216行
4：diy/dayrui/libraries/Dip.php 84行
把所有的{}改為[].
②
1：diy/dayrui/libraries/Template.php 84行
把
!$system['order'] && $system['order'] = $system['flag'] ? 'updatetime_desc' : $action == 'hits' ? 'hits' : 'updatetime'; // 默認(rèn)排序參數(shù)
改成
!$system['order'] &&($system['order'] =$system['flag'] ? 'updatetime_desc' : $action) == 'hits' ? 'hits' : 'updatetime'; // 默認(rèn)排序參數(shù)
這樣就ok，適用所有版本升級(jí)為最新最新版本。
