• 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();
    }

    function.php   公共方法分页显示调用

    function getpage($count, $listRows) {
    $p = new ThinkPage($count, $listRows=2);
    $p->setConfig('header', '<li class="rows">共<b>%TOTAL_ROW%</b>条记录&nbsp;第<b>%NOW_PAGE%</b>页/共<b>%TOTAL_PAGE%</b>页</li>');

    $p->setConfig('last', '末页');
    $p->setConfig('theme', '%FIRST%%UP_PAGE%%LINK_PAGE%%DOWN_PAGE%%END%%HEADER%');
    $p->lastSuffix = false;//最后一页不显示为总页数
    return $p;
    }
