实现分页的处理页面为:
<?php require_once "DBDA.class.php"; $db = new DBDA(); $name = $_POST["name"]; $tj = " 1=1 "; if(!empty($name)){ $tj = " areaname like '%{$name}%' "; } $sql = "select count(*) from chinastates where {$tj}"; echo $db->strquery($sql);
查找显示数据并实现查询功能的处理页面为:
<?php require_once "DBDA.class.php"; $db = new DBDA(); $page = $_POST["page"]; $pcount = $_POST["pcount"]; $name = $_POST["name"]; $tj = " 1=1 "; if(!empty($name)){ $tj = " areaname like '%{$name}%' "; } $tg = ($page-1)*$pcount; $sql = "select * from chinastates where {$tj} limit {$tg},{$pcount}"; echo $db->jsonquery($sql);
