  • TP条件查询和分页查询

    一、条件查询

    前端页面

    <!doctype html>
    <html>
    <head>
    	<meta charset="utf-8">
    	<title></title>		
        <link href="../../../../../bootstrap/css/bootstrap.min.css" rel="stylesheet" type="text/css">
    </head>
    <body>
    <div class="panel panel-primary">
        <div class="panel-heading">
            <h3 class="panel-title" style="text-align:center;">汽车详情表</h3>
        </div>
        <div class="panel-body">
    	<form action="__ACTION__" method="post" class="form-inline" role="form">
    	<div class="form-group">
    		<label for="name">请输入关键字:</label>
    		<input type="text" class="form-control" placeholder="请输入关键字" name="name"value="{$name}">
    		<input type="submit" class="btn btn-primary btn-sm" value="查询"/>
    	</div>
    		<table class="table" style="100%;">
    		  <thead>
    			<tr>
    			  <th>代号</th>
    			  <th>名称</th>
    			  <th>系列</th>
    			  <th>出产时间</th>
    			  <th>油耗</th>
    			  <th>功率</th>
    			  <th>排量</th>
    			  <th>价格</th>
    			</tr>
    		  </thead>
    		<foreach name="cars" item="v">
    		  <tbody>
    			<tr class="danger">
    			  <th>{$v.code}</th>
    			  <td>{$v.name}</td>
    			  <td>{$v.brand}</td>
    			  <td>{$v.time}</td>
    			  <td>{$v.oil}</td>
    			  <td>{$v.powers}</td>
    			  <td>{$v.exhaust}</td>
    			  <td>{$v.price}</td>
    			</tr>
    		  </tbody>
    		</foreach>
    		</table>
    	</form>
        </div>
    </div>
    </body>
    </html>
    

     处理页面

    <?php
    namespace HomeController;
    use ThinkController;
    class SelectController extends Controller{
        
        public function select(){
            $db = D("car");
            $tj = " 1=1 ";
            $name = "";//表单中保存查询的关键字
            if(!empty($_POST["name"])){
                $name = $_POST["name"];
                $tj = " name like '%{$name}%' ";
            }
            $arr = $db
                ->where($tj)
                ->select();
            $this->assign("cars",$arr);
            $this->assign("name",$name);//表单中保存查询的关键字
            $this->show();
        }
    }
    

     

    二、条件分页查询

    	<div>
    		<div>
    			<h3 style="text-align:center;">汽车详情表</h3>
    		</div>
    		<div>
    		<form action="__ACTION__" method="get">
    		<div>
    			<label >请输入关键字:</label>
    			<input type="text" placeholder="请输入关键字" name="name" value="{$name}">
    			<input type="submit" value="查询"/>
    		</div>
    			<table  style="100%; text-align:center;" border="1" cellpadding="0" cellspacing="0">
    			  <thead>
    				<tr>
    				  <th>代号</th>
    				  <th>名称</th>
    				  <th>系列</th>
    				  <th>出产时间</th>
    				  <th>油耗</th>
    				  <th>功率</th>
    				  <th>排量</th>
    				  <th>价格</th>
    				</tr>
    			  </thead>
    			<foreach name="cars" item="v">
    			  <tbody>
    				<tr class="danger">
    				  <th>{$v.code}</th>
    				  <td>{$v.name}</td>
    				  <td>{$v.brand}</td>
    				  <td>{$v.time}</td>
    				  <td>{$v.oil}</td>
    				  <td>{$v.powers}</td>
    				  <td>{$v.exhaust}</td>
    				  <td>{$v.price}</td>
    				</tr>
    			  </tbody>
    			</foreach>
    			</table>
    		</form>
    		</div>
    	<div>{$pagelist}</div>
    </div>
    
    <?php
    namespace HomeController;
    use ThinkController;
    class SelectController extends Controller{
    	
    	public function select(){
    		$db = D("car");
    		$tj = " 1=1 ";
    		$name = "";//表单中保存查询的关键字
    		if(!empty($_GET["name"])){
    			$name = $_GET["name"];
    			$tj = " name like '%{$name}%' ";
    		}
    		$arr = $db
    			->where($tj)
    			->page($_GET["p"],6)//分页
    			->select();
    		$zts = $db
    			->where($tj)
    			->count();//总条数
    		$page = newThinkPage($zts,6);//实例化页数和条数
    		$page->setConfig("prev","上一页");//把<<改为上一页
    		$page->setConfig("next","下一页");//把>>改为下一页
    		$pagelist = $page->show();//分页显示
    		$this->assign("pagelist",$pagelist);//往前端传分页数据
    		$this->assign("name",$name);//表单中保存查询的关键字
    		$this->assign("cars",$arr);
    		$this->show();
    	}
    }
    

     

    在这里可以修改分页的样式
