管理员的添加、编辑功能
1.控制器类代码
<?php
namespace app\admins\controller;
use think\Controller;
use Util\SysDb;
class Admin extends Base{
public function index(){
// 加载管理员列表
$data['lists'] = $this->db->table('admins')->order('id desc')->lists();
return $this->fetch('',$data);
}
// 添加管理员
public function add(){
$id = (int)input('get.id');
$data['item'] = $this->db->table('admins')->where(array('id'=>$id))->item();
return $this->fetch('',$data);
}
// 保存管理员
public function save(){
$id = (int)input('post.id');
$data['username'] = trim(input('post.username'));
$data['gid'] = (int)input('post.gid');
$data['truename'] = trim(input('post.truename'));
$data['status'] = (int)input('post.status');
$password = input('post.password');
if(!$data['username']){
exit(json_encode(array('code'=>1,'msg'=>'用户名不能为空')));
}
if(!$data['gid']){
exit(json_encode(array('code'=>1,'msg'=>'角色不能为空')));
}
if(!$data['truename']){
exit(json_encode(array('code'=>1,'msg'=>'姓名不能为空')));
}
if($id==0 && !$password){
exit(json_encode(array('code'=>1,'msg'=>'请输入密码')));
}
if($password){
$data['password'] = md5($password);
}
$res = true;
if($id == 0){
$item = $this->db->table('admins')->where(array('username'=>$data['username']))->item();
if($item){
exit(json_encode(array('code'=>1,'msg'=>'该用户已经存在')));
}
$data['add_time'] = time();
$res = $this->db->table('admins')->insert($data);
}else{
$res = $this->db->table('admins')->where(array('id'=>$id))->update($data);
}
if($res){
exit(json_encode(array('code'=>0,'msg'=>'保存成功')));
}else{
exit(json_encode(array('code'=>1,'msg'=>'保存失败')));
}
}
// 删除管理员
public function delete(){
$id = (int)input('post.id');
$res = $this->db->table('admins')->where(array('id'=>$id))->delete();
if(!$res){
exit(json_encode(array('code'=>1,'msg'=>'删除失败')));
}
exit(json_encode(array('code'=>0,'msg'=>'删除成功')));
}
}
2.视图类代码
（1）.编辑页面
<!DOCTYPE html>
<html>
<head>
<title></title>
<link rel="stylesheet" type="text/css" href="/static/plugins/layui/css/layui.css">
<script type="text/javascript" src="/static/plugins/layui/layui.js"></script>
<style type="text/css">
.header span{background: #009688;margin-left: 30px;padding: 10px;color: #ffffff;}
.header button{float: right;margin-top: -5px;}
.header div{border-bottom: solid 2px #009688;margin-top: 8px;}
</style>
</head>
<body style="padding: 10px;">
<div class="header">
<span>管理员列表</span>
<button class="layui-btn layui-btn-sm" onclick="add()">添加</button>
<div></div>
</div>
<table class="layui-table">
<thead>
<tr>
<th>ID</th>
<th>用户名</th>
<th>真实姓名</th>
<th>角色</th>
<th>状态</th>
<th>添加时间</th>
<th>操作</th>
</tr>
</thead>
<tbody>
{volist name='$lists' id="vo"}
<tr>
<td>{$vo.id}</td>
<td>{$vo.username}</td>
<td>{$vo.truename}</td>
<td>{$vo.gid}</td>
<td>{$vo.status==0?'正常':'<span style="color: red;">禁用</span>'}</td>
<td>{:date('Y-m-d H:i:s',$vo.add_time)}</td>
<td>
<button class="layui-btn layui-btn-xs" onclick="add({$vo.id})">编辑</button>
<button class="layui-btn layui-btn-danger layui-btn-xs" onclick="del({$vo.id})">删除</button>
</td>
</tr>
{/volist}
</tbody>
</table>
</body>
</html>
<script type="text/javascript">
layui.use(['layer'],function(){
layer = layui.layer;
$ = layui.jquery;
});
// 添加
function add(id){
layer.open({
type:2,
title:id>0?'编辑管理员':'添加管理员',
shade:0.3,
area:['480px','420px'],
content:'/index.php/admins/admin/add?id='+id
});
}
// 删除
function del(id){
layer.confirm('确定要删除吗？',{
icon:3,
btn:['确定','取消']
},function(){
$.post('/index.php/admins/admin/delete',{'id':id},function(res){
if(res.code>0){
layer.alert(res.msg,{'icon':2});
}else{
layer.msg(res.msg,{'icon':1});
setTimeout(function(){window.location.reload();},1000);
}
},'json');
});
}
</script>
（2）.增加页面
<!DOCTYPE html>
<html>

<script type="text/javascript" src="/static/plugins/layui/layui.js"></script>
</head>
<body style="padding: 10px;">
<form class="layui-form">
<input type="hidden" name="id" value="{$item.id}">
<div class="layui-form-item">
<label class="layui-form-label">用户名</label>

</div>
</div>
<div class="layui-form-item">
<label class="layui-form-label">角色</label>
<div class="layui-input-inline">
<select name="gid">
<option value="1">系统管理员</option>

<div class="layui-input-inline">
<input type="checkbox" name="status" lay-skin="primary" title="禁用" value="1" {$item.status?'checked':''}>
</div>
</div>
</form>
<div class="layui-form-item">
<div class="layui-input-block">
<button class="layui-btn" onclick="save()">保存</button>
</div>
</div>
</body>
</html>
<script type="text/javascript">
layui.use(['layer','form'],function(){
var form = layui.form;
layer = layui.layer;
$ = layui.jquery;
});
function save(){
var id = parseInt($('input[name="id"]').val());
var username = $.trim($('input[name="username"]').val());

}else{
layer.msg(res.msg,{'icon':1});
setTimeout(function(){parent.window.location.reload();},1000);
}
},'json');
}
</script>
