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="{$name}">
<input type="submit" class="btn btn-primary btn-sm" value="查询"/>
</div>
<table class="table" style="width:100%;">
<thead>
<tr>
<th>代号</th>
<th>名称</th>
<th>系列</th>
<th>出产时间</th>
<th>油耗</th>
<th>功率</th>
<th>排量</th>
<th>价格</th>
</tr>
</thead>
<foreach name="cars" item="v">
<tbody>
<tr class="danger">
<th>{$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 Home\Controller;
use Think\Controller;
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="width: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 Home\Controller;
use Think\Controller;
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
$page = new\Think\Page($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
