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>

--------------------------------------------------------------------------------------------------------------------------------

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();
}
