菜单的添加功能
1.控制器代码
<?php
namespace app\admins\controller;
use think\Controller;
use Util\SysDb;
class Menu extends Base{
public function index(){
$pid = (int)input('get.pid');
$where['pid'] = $pid;
// 加载菜单列表
$data['lists'] = $this->db->table('admin_menus')->where($where)->order('ord asc')->lists();
$data['pid'] = $pid;
// 子菜单
if($pid>0){
$parent = $this->db->table('admin_menus')->where(array('mid'=>$pid))->item();
$data['backid'] = $parent['pid'];
}
return $this->fetch('',$data);
}
// 添加、编辑菜单
public function add(){
$pid = (int)input('get.pid');
$mid = (int)input('get.mid');
$data['parent_menu'] = $this->db->table('admin_menus')->where(array('mid'=>$pid))->item();
$data['menu'] = $this->db->table('admin_menus')->where(array('mid'=>$mid))->item();
return $this->fetch('',$data);
}
// 保存菜单
public function save(){
$mid = (int)input('post.mid');
$data['pid'] = (int)input('post.pid');
$data['title'] = trim(input('post.title'));
$data['controller'] = trim(input('post.controller'));
$data['method'] = trim(input('post.method'));
$data['ord'] = (int)input('post.ord');
$data['ishidden'] = (int)input('post.ishidden');
$data['status'] = (int)input('post.status');
if($data['title'] == ''){
exit(json_encode(array('code'=>1,'msg'=>'菜单名称不能为空')));
}
if($data['pid']>0 && $data['controller'] == ''){
exit(json_encode(array('code'=>1,'msg'=>'控制器名称不能为空')));
}
if($data['pid']>0 && $data['method'] == ''){
exit(json_encode(array('code'=>1,'msg'=>'方法名称不能为空')));
}
if($mid){
$res = $this->db->table('admin_menus')->where(array('mid'=>$mid))->update($data);
}else{
$res = $this->db->table('admin_menus')->insert($data);
}
if(!$res){
exit(json_encode(array('code'=>1,'msg'=>'保存失败')));
}else{
exit(json_encode(array('code'=>0,'msg'=>'保存成功')));
}
}
// 删除菜单
public function delete(){
$mid = (int)input('post.mid');
$res = $this->db->table('admin_menus')->where(array('mid'=>$mid))->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')));
}
}
