thinkphp3.2.3實現多條件查詢實例.

                $data = M("datainfo");

			$projectsname = I('get.projectsname');//前台提交的模糊查詢字段
			// 查詢條件
			$where = "";
			empty($projectsname)?($where=""):($where="status=1 and projectsname like '%".$projectsname."%' or projectsname like '%".$projectsname."' or projectsname like '".$projectsname."%'");

		    $count = $data->where($where)->count(); // 查詢滿足要求的總記錄數
		    $Page = new Page($count, 50); // 實例化分頁類 傳入總記錄數和每頁顯示的記錄數(50)

		    // 配置前台分頁的顯示頁
		    $Page->setConfig('header', '共%TOTAL_ROW%條');
		    $Page->setConfig('first', '首頁');
		    $Page->setConfig('last', '共%TOTAL_PAGE%頁');
		    $Page->setConfig('prev', '上一頁');
		    $Page->setConfig('next', '下一頁');
		    $Page->setConfig('link', 'indexpagenumb'); //pagenumb 會替換成頁碼
		    $Page->setConfig('theme', '%HEADER% %FIRST% %UP_PAGE% %LINK_PAGE% %DOWN_PAGE% %END%');
		    // 分頁顯示輸出
		    $show = $Page->show(); 
		    // 進行分頁數據查詢 注意limit方法的參數要使用Page類的屬性
		    $list = $data->where($where)->order('id desc')->limit($Page->firstRow . ',' . $Page->listRows)->select();
		    $this->assign('page', $show);
		    $this->assign("list", $list);
