关于分页函式的使用说明
\n
/*#### 检索分页函式 ####
Int HALT – 检索结果仅分1页时是否(1/0)显示页码条
Int LRLIST – (页码条显示页码数-1)/2
Int ECHOCNT – 检索时每页显示记录的数量
Int paper – 页数,预提取:paper=HTTP_GET_VARS[paper];
Varchar table – 数据表名,预附值:table=”db.table”;
Varchar where – 检索条件,预附值:where=”where field=@#value@#”;
Varchar enwhere – 将原where进行两次base64_encode()编码后以GET的方式提交
Varchar splitstr – 页码条输出字串,执行函式后在相应的位置执行 echo splitstr;
函式调用前需获取变量 –
paper=HTTP_GET_VARS[paper];
sumcnt=HTTP_GET_VARS[sumcnt];
enwhere=HTTP_GET_VARS[enwhere];
Return (Varchar where) – 分页后检索语句的检索条件
注意:本函式需调用出错处理函式 nerror(error);
