How to link to database through ThinkPHP
Make the following configuration in the configuration file to connect to the database

//'配置项'=>'配置值'
'DB_TYPE' => 'mysql', // 数据库类型
'DB_HOST' => 'localhost', // 服务器地址
'DB_NAME' => 'shop', // 数据库名
'DB_USER' => 'root', // 用户名
'DB_PWD' => '123', // 密码
'DB_PORT' => '3306', // 端口
'DB_PREFIX' => 'sw_', // 数据库表前缀
);CreateModelModel
Cut the 'Home/Model' folder to the Application folder, and let Home and Admin are used together.
My database indicates that it is goods. First, create a model class with the same name as the database
GoodsModel.class.php# Methods for instantiating models in ##
<?php
namespace Model;
use Think\Model;
class GoodsModel extends Model{
}:
First method:
Define a controller(GoodsController)To call thisGoodsModel class
<?php
namespace Admin\Controller;
use Model\GoodsModel;
use Think\Controller;
class GoodsController extends Controller{
public function test1(){
$goods = new GoodsModel();
echo '<pre class="brush:php;toolbar:false">';
var_dump($goods);
}
}Second type:
Use M function for instantiation:
<?php
namespace Admin\Controller;
use Model\GoodsModel;
use Think\Controller;
class GoodsController extends Controller{
public function test1(){
$goods = M('goods');
echo '<pre class="brush:php;toolbar:false">';
var_dump($goods);
}
}Third type:
Use Dfunction
<?php
namespace Admin\Controller;
use Model\GoodsModel;
use Think\Controller;
class GoodsController extends Controller{
public function test1(){
$goods = D('goods');
echo '<pre class="brush:php;toolbar:false">';
var_dump($goods);
}
}method is the same as Dmethod
M()Similar to new Model()
D()Similar tonew GoodsModel()
Tips: You can see the information of the goods table. There is no code written in the model. All business logic is implemented by the Model class
Operations on tables
Add: M('Table name')-> ;add($date);
Delete:M('Table name')->delete($id);
Update: M('Table name')->save($date);
Query: M('Table Name')->select();
Normal query (display all products)
Code in GoodsController:
<?php
namespace Admin\Controller;
use Model\GoodsModel;
use Think\Controller;
class GoodsController extends Controller{
public function showlist(){
$list = M('goods')->select();
$this->assign('list', $list);
$this->display();
}
}Remove from the template
<volist name="list" id="vo" >
<tr id="product1">
<td>{$i}</td>
<td><a href="#">{$vo.goods_name}</a></td>
<td>{$vo.goods_number}</td>
<td>{$vo.goods_price}</td>
<td><img src="../../../Application/Admin/Public/img/20121018-174034-58977.jpg" height="60" width="60"></td>
<td><img src="../../../Application/Admin/Public/img/20121018-174034-97960.jpg" height="40" width="40"></td>
<td>{$vo.goods_brand_id}</td>
<td>{$vo.goods_create_time}</td>
<td><a href="#">修改</a></td>
<td><a href="javascript:;" onclick="delete_product(1)">删除</a></td>
</tr>
