laravel:在null上调用成员函数delete()

问题描述：

当我尝试通过单击删除按钮将删除功能添加到帖子时，出现了此错误. 我在哪里做错了?

I got this error when I tried to add a feature of delete, to the posts just by clicking on the delete button. Where am I doing wrong?

在PostController中删除发布函数:

Delete post function in PostController:

public function getDeletePost($post_id)
{
    $post =Post::where('id',$post_id)->first();
    $post->delete();
    return redirect()->route('dashboard')->with(['message'=> 'Successfully deleted!!']);
}

答

$post object为null.也许您发送的是错误的$ post_id.如果您在删除之前检查帖子是否存在，则可以避免该错误.

$postobject is null. Maybe you are sending a wrong $post_id. If you check that the post exists before delete you avoid that error.

public function getDeletePost($post_id)
{
    $post =Post::where('id',$post_id)->first();

    if ($post != null) {
        $post->delete();
        return redirect()->route('dashboard')->with(['message'=> 'Successfully deleted!!']);
    }

    return redirect()->route('dashboard')->with(['message'=> 'Wrong ID!!']);
}
