类的属性不存在:app\index\model\Topic->id
问题一：
有点懵了。这个是哪里错了？
问题二：：关于tags标签的编辑以后的保存，请老师写一个具体的代码。
最后附上我的源代码：
一：Topic.php:
<?php
namespace app\index\controller;
use app\index\model\Tag as TagModel;
use app\index\model\Topic as TopicModel;
use app\index\model\TopicTag as TopicTagModel;
class Topic extends \think\Controller
{
public function newTopic()
{
if(request()->isPost())
{
$postData = input('post.');
$topic = new TopicModel();
$user = session('user');
$topic->title = $postData['title'];
$topic->content = $postData['body'];
$topic->category_id = $postData['category_id'];
$topic->created_at = intval(microtime(true));
$topic->user_id = $user->id;
$topic->save();
// 处理标签
$tags = $postData['tags'];
foreach ($tags as $tag)
{
if(is_numeric($tag))
{
$this->createTopicTag($tag,$topic->id);
continue;
}
$newTag = $this->createTag($tag);
$this->createTopicTag($newTag->id,$topic->id);
}
$this->success('恭喜，帖子发布成功。');
}
$this->assign([
'user' => session('user'),
'category' => config('category'),
'tags' => TagModel::all(),
]);
echo $this->fetch('new_topic');
}
private function createTopicTag($tagId,$topicId)
{
$topic_tag = new TopicTagModel();
$topic_tag->topic_id = $topicId;
$topic_tag->tag_id = $tagId;
$topic_tag->save();
}
private function createTag($tagname)
{
$tag = new TagModel();
$tag->name = $tagname;
$tag->save();
return $tag;
}
public function detail()
{
$topicId = input('get.id');
$topic = TopicModel::getTopic($topicId);
$user = session('user');
$categoryNames = getcategoryNames($topic->category_id);
$tags = TopicTagModel::getTagsFromTagsByTopicId($topicId);
$this->assign([
'user' => $user,
'topic' => $topic,
'category' => config('category'),
'categoryNames' => $categoryNames,
'tags' => $tags,
]);
echo $this->fetch('detail');
}
public function edit_Topic()
{
if(request()->isPost())
{
$postData = input('post.');
$topic = new TopicModel();
$topicId = $postData['topicId'];
var_dump($topicId);
$user = session('user');
$list=[
'title' => $postData['title'],
'content' => $postData['body'],
'category_id' => $postData['category_id'],
'created_at' => intval(microtime(true)),
'user_id' => $user->id,
];
$Topic = new TopicModel();
$Topic->save($list,['id' => $topicId]);
// 处理标签
$tags = $postData['tags'];
foreach ($tags as $tag)
{
if(is_numeric($tag))
{
$this->createTopicTag($tag,$topic->id);
continue;
}
$newTag = $this->createTag($tag);
$this->createTopicTag($newTag->id,$topic->id);
}
$this->success('恭喜，帖子编辑成功。');
}else{
// 显示原来的默认信息
$topicId = input('get.topicId');
$user = session('user');
$topic = TopicModel::getTopic($topicId);
$categoryNames = getcategoryNames($topic->category_id);
$tagsValue = TopicTagModel::getTagsFromTagsByTopicId($topicId);
$tags = TagModel::all();
$this->assign([
'topicId' => $topicId,
'user' => $user,
'topic' => $topic,
'category' => config('category'),
'categoryNames' => $categoryNames,
'tagsValue' => $tagsValue,
'tags' => $tags,
]);
echo $this->fetch('edit_Topic');
}
}
}

你好，1、首先添加编辑按钮，并通过href连接传递编辑帖子的id，
<a href="<?=url('topic/editPost');?>?topicId=<?=$topic->id;?>">编辑</a>2、 根据传递的id获取帖子的详细信息显示在编辑页面
public function editPost() {
$topicId = input('get.topicId');
$topicTags = TopicTagModel::where(['topic_id' => $topicId])->select();
$selectTags = [];
foreach($topicTags as $topicTag) {
$selectTags[] = $topicTag->tag_id;
}
$this->assign([
'user' => session('user'),
'topic' => TopicModel::get($topicId),
'category' => config('category'),
'tags' => TagModel::all(),
'selectTags' => $selectTags,
]);
echo $this->fetch('edit_topic');
}3、然后根据帖子id以及编辑后帖子的详细信息跟新数据库信息
action="<?=url('topic/newTopic');?>?topicId=<?=$topic->id;?>"public function newTopic(){
if (request()->isPost()) {
$postData = input('post.');
$user = session('user');
$topicId = input('get.topicId');
if (!$topicId) {
$topic = new TopicModel();
} else {
$topic = TopicModel::find($topicId);
}
$topic->title = $postData['title'];
$topic->category_id = $postData['category_id'];
$topic->content = $postData['content'];
$topic->user_id = $user->id;
$topic->created_at = intval(microtime(true));
$topic->save();
// 标签处理
$tags = $postData['tags'];
TopicTagModel::where(['topic_id' => $topic->id])->delete();
foreach($tags as $tag) {
if (is_numeric($tag)) {
$this->createTopicTag($tag, $topic->id);
continue;
}
$newTag = $this->createTag($tag);
$this->createTopicTag($newTag->id, $topic->id);
}
$message = $topicId ? '编辑帖子成功！' : '发表帖子成功！';
return $this->success($message, 'topic/index');
}
$tags = TagModel::all();
$this->assign([
'user' => session('user'),
'category' => config('category'),
'tags' => $tags
]);
echo $this->fetch('new_topic');}
