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
