这个函数会将图片保存到项目文件的Cache目录的Upload/....什么什么的目录下。而且也返回了这个完整路径跟前端，前端拿着这个再去请求后台接口保存这个路径。保存图片的后台代码如下：
首先是控制层：
adds();
$ajaxReturnData['status'] = 1;
$ajaxReturnData['message'] = 'success';
}catch (Exception $e){
$ajaxReturnData['status'] = 0;
$ajaxReturnData['message'] = 'fail';
}
$this->ajaxReturn($ajaxReturnData);
}
然后是模型层：（我之前犯傻的是，应该直接把数组，也就是$images直接保存进去就行了，不用json_encode()）
find($user_id);
$data = [];
$data['user_id'] = $user_id;
$data['user_name'] = $user['nickname'];
$data['user_img'] = $user['imageurl'];
$data['content'] = $content;
$data['images'] = $images;
$data['create_time'] = time();
if ($this->add($data) === false) {
throw new Exception('OPERATION_FAILED');
}
}
保存好了之后，接下来如何在前端中显示图片呢？关键在于保存图片数组到数据库里，如何让它取出来的时候转为数组。代码如下：
控制层：
my_moments();
$ajaxReturnData['status'] = 1;
$ajaxReturnData['message'] = 'success';
$ajaxReturnData['data'] = $data;
}catch (Exception $e){
$ajaxReturnData['status'] = 0;
$ajaxReturnData['message'] = 'fail';
}
$this->ajaxReturn($ajaxReturnData);
}
模型层：（这里使用了json_decode($array,true)方法，打印出来就是数组了）
find($user_id);
if($user['is_doctor'] == 1){
$conditions = [];
$conditions['user_id'] = $user_id;
$doctor = D(self::$DOCTOR_MODEL)->where($conditions)->find();
$identity = $doctor['hospital']. "" . $doctor['grade'];
}else{
$identity = '';
}
$conditions = [];
$conditions['user_id'] = $user_id;
$moments = $this->where($conditions)->order('create_time desc')->select();
for($i = 0 ; $i < count($moments) ; $i ++){
$moments[$i]['images'] = json_decode($moments[$i]['images'],true);
}
$data = [];
$data[0] = $user;
$data[1] = $moments;
$data[2] = $identity;
return $data;
}
最后，动态页面如何显示图片呢？
主要我还在做九宫格图片的适配，就不贴代码了，主要是图片src需要加前缀，也就是你的域名。这样就能显示出来啦~
不相信你能看到最后，哈哈~我写的太多了
总结
以上所述是小编给大家介绍的微信小程序仿朋友圈发布动态界面，希望对大家有所帮助，如果大家有任何疑问欢迎给我留言，小编会及时回复大家的！
