老师是这样：edit_topic在点击保存的时候，报如下错误
这是topic控制器里面的edit_topic方法
public function edit_Topic()
{
$user =session('user');
if(!$user){
$this->error('您还没有登陆，无法编辑，请登录后再操作！','Index/login');
}
if(request()->isPost())
{
$postData = input('post.');
$topic = new TopicModel();
$topicId = $postData['topicId'];
$user = session('user');
$Topic = new TopicModel();
$data = [
'title' => $postData['title'],
'content' => $postData['body'],
'category_id' => $postData['category_id'],
'created_at' => intval(microtime(true)),
'user_id' => $user->id,
];
$Topic->where('id',$topicId)->update($data);
// 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 $this->fetch('edit_Topic');
}
}
你好，报错是说的是你用的不是一个对象，也就是说要么$topic不是对象，要么$topic->user不是对象，小慕测试了一下发现是因为有的帖子用户id字段对应的用户在用户表里是不存在的，所以才会报这个错误，你也可以自己在控制器里打印一下试试，在控制器里循环遍历时能够打印出一部分帖子的用户名，但下面还是会报这个non-object错误，怀疑是有的$topic里对应的用户数据没有，所以用了判断，如果是对象才让它打印，这样过滤掉那些不存在的用户就没有报错了，然后把下图测试代码注释掉，去html页面也使用这样的判断
topic_list.html判断
foreach循环时加一个判断条件：
另外你的detail页面的这个tags这里了，如下，as前面变量都一样
您说的edit_topic没有id属性小慕没搞明白你的意思，你这里贴出的控制器不是topic控制器，同学可以参考$topic->user这个问题的排错方式，认真检查一下问题出在哪里，排查错误很需要耐心的，加油~
