海洋cms地图页按首字母调用时0-9内容不显示的解决方法

编辑 /include/main.class.php 文件第1294行，将

1. if(!empty($vletter)) $whereLetter=" and m.v_letter ='".strtoupper($vletter)."' "; else $whereLetter="";

复制代码

修改为

1. if(!empty($vletter))if(strlen($vletter)>1){$whereLetter=" and m.v_letter  between '0' and '9'";}else{$whereLetter=" and m.v_letter ='".strtoupper($vletter)."' ";} else $whereLetter="";

复制代码

一样不显示
