ThinkPHP分页查询功能实现
分页查询网页html部分：
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="/pretty/Public/Home/dist/css/paging.css"/>
</head>
<body>
//查询
<input type="text" id="projectName" name="projectName" value="{$projectName}"/>
<input type="button" value="项目查询" id="btnSearch" name="btnSearch"/>
//分页输出
<div align="center" id="Page">
{$page}
</div>
<script type="text/javascript">
$(function(){
$('#btnSearch').click(function() {
var url = "{:U('/Home/Project/index')}";
url = url.substring(0, url.length - 5);
url = url + "/projectName/"+$('#projectName').val()+".html";
//alert(url);
location.href = url;
});
});
</script>
</body>
</html>

Controller控制器部分:
public function index() {
$userinfo = session("userinfo");
$SHOP_ID = $userinfo[0]["shopid"];
$COMPANY_ID = $userinfo[0]['companyid'];
$USER_ID = $userinfo[0]['id'];
$typeid = I("typeid");
$projectName = I("projectName");
$model = D("Home/ProjectType");
if (!$typeid) {
$typeMap['companyId'] = array('eq', $COMPANY_ID);
$type = $model -> where($typeMap) -> find();
$typeid = $type["id"];
}
$map['companyId'] = array('eq', $COMPANY_ID);
$typeList = $model -> where($map) -> select();
$this -> assign('typeList', $typeList);
$infoModel = D("Home/ProjectInfo");
$infoMap['companyId'] = array('eq', $COMPANY_ID);
$infoMap['typeId'] = array('eq', $typeid);
//根据用户传过来的值模糊查询
if (empty($projectName) == FALSE) {
$where['proName'] = array('LIKE', '%' . $projectName . '%');
$where['projectNo'] = array('LIKE', '%' . $projectName . '%');
$where['_logic'] = 'OR';
$infoMap['_complex'] = $where;
// $sql = $infoModel -> getLastSql();
}
$totalRows = $infoModel -> where($infoMap) -> count();
$page = getpage($totalRows, $listRows);
$list = $infoModel -> field(true) -> where($infoMap) -> order('id') -> limit($page -> firstRow . ',' . $page -> listRows) -> select();
$this -> assign('projectName', $projectName);//传值
$this -> assign('infoList', $list);// 赋值数据集
$show = $page -> show();// 分页显示输出
$this -> assign('page', $show);// 赋值分页输出
$this -> assign('typeid', $typeid);
$this -> assign('navActive', "index");
$this -> display();
