关联两个数据表，在Model里建立StuModel.class.php: 在view中建立Stu文件夹，建立主页面index.html： 在Stu中建立修改页面edit.html： 在Controller中建立StuController.class.php： ......
关联两个数据表，在Model里建立StuModel.class.php:
<?php
//Belongs_to 关联表示当前模型从属于另外一个父对象
namespace Admin\Model;
use Think\Model\RelationModel;
class StuModel extends RelationModel
{
protected $_link = array(
'Clas' => array(
'mapping_type' => self::BELONGS_TO,
'class_name' => 'Clas',
'foreign_key' => 'clas_id',
// 'mapping_name' => 'dept',
),
);
}
在view中建立Stu文件夹，建立主页面index.html：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<table>
<tr>
<td>名字</td>
<td>性别</td>
<td>生日</td>
<td>班级</td>
<td>修改</td>
</tr>
<volist name="Stu" id="vo">
<tr>
<td>
{$vo.uname}
</td>
<td>
<if condition="$vo.sex eq 1">
男
<else/>
女
</if>
</td>
<td>
{$vo.birthday}
</td>
<td>
{$vo.Clas.cname}
</td>
<td><a href="{:U('Stu/editShow',array('id'=>$vo[id]))}">编辑</a></td>
</tr>
</volist>
</table>
<hr>
<table>
<tr>
<td>名字</td>
<td>性别</td>
<td>生日</td>
<td>班级</td>
<td>修改</td>
</tr>
<tbody id="data">
</tbody>
</table>
<input type="hidden" id="page" value="1">
<input type="submit" id="prev" value="上一页">
<input type="submit" id="next" value="下一页">
<script src="__JS__/jquery-2.2.3.min.js"></script>
<script>
function dataGet(pag_num,count) {
//ajax
$.ajax({
url:'{:U("Stu/ajaxSelect")}',
dataType:'json',
type:'post',
data:{
pag_num:pag_num,
count:count
},
success:function (data) {
var str='';
for (var i in data){
if (data[i].sex == 1){
data[i].sex = '男';
}else{
data[i].sex = '女';
}
str +=
'<tr>' +
' <td>' +
data[i].uname +
' </td>' +
' <td>' +
data[i].sex +
' </td>' +
' <td>' +
data[i].birthday.substr(0,10) +
' </td>' +
' <td>' +
data[i].Clas.cname +
' </td>' +
' <td><a href="{:U("Stu/editShow")}?id=' + data[i].id + '">编辑</a>' +
'</td>' +
'</tr>'
}
$('#data').html(str);
$('#page').val(pag_num);
}
})
}
//数据显示数量
dataGet(1,1);
//点击切换
$('#prev').click(function () {
var page = parseInt($('#page').val())
dataGet(page-1,1);
});
$('#next').click(function () {
var page = parseInt($('#page').val())
dataGet(page+1,1);
})
</script>
</body>
</html>
在Stu中建立修改页面edit.html：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<table>
<tr>
<td>名字</td>
<td>性别</td>
<td>生日</td>
<td>班级</td>
<td>修改</td>
</tr>
<form action="{:U('Stu/editPost')}" method="post">
<tr>
<td><input type="text" name="uname" value="{$stu.uname}"></td>
<td>
<if condition="$stu['sex'] eq 1">
<input type="radio" name="sex" value="1" id="man" checked><labl for="man">男</labl>
<input type="radio" name="sex" value="0" id="woman"><labl for="woman">女</labl>
<else/>
<input type="radio" name="sex" value="1" id="man"><labl for="man">男</labl>
<input type="radio" name="sex" value="0" id="woman" checked><labl for="woman">女</labl>
</if>
</td>
<td><input type="text" name="birthday" value="{$stu.birthday}"></td>
<td>
<select name="clas_id">
<option value="">选择班级</option>
<volist name="clas" id="vo">
<if condition="$stu['clas_id'] eq $vo['id']">
<option value="{$vo.id}" selected>{$vo.cname}</option>
<else/>
<option value="{$vo.id}">{$vo.cname}</option>
</if>
</volist>
</select>
</td>
<td>
<input type="hidden" name="id" value="{$stu.id}">
<input type="submit" value="提交">
</td>
</tr>
</form>
</table>
</body>
</html>
在Controller中建立StuController.class.php：
<?php
namespace Admin\Controller;
use Think\Controller;
class StuController extends Controller
{
public function index(){
$db_stu = D('Stu');
$data_stu = $db_stu->relation(true)->select();
// dump($data_stu);
$this->assign('Stu',$data_stu);
$this->display();
}
public function ajaxSelect(){
$pag = I('post.pag_num');
$count = I('post.count');
$db_stu = D('stu');
$data_stu = $db_stu->relation(true)->page($pag,$count)->select();
$this->ajaxReturn($data_stu);
}
public function editShow(){
if (IS_GET){
$id = I('get.id');
// dump($id);
$db_stu = M('Stu');
$db_clas = M('Clas');
$data_stu = $db_stu->where('id = '.$id)->find();
$data_clas = $db_clas->where('status = 1')->select();
$this->assign('clas',$data_clas);
$this->assign('stu',$data_stu);
$this->display('Stu/edit');
}
}
public function editPost(){
if (IS_POST){
$data = I('post.');
// dump($data);
$db_stu = M('stu');
$db_stu->save($data);
// dump($m);
$this->success('成功','index');
}
}
}
