Add category slug in post page - content-management-system

Question

I am beginner in october cms and using rainlab blog plugin for my personal blog.
I want to display category slug in the url of blog post page, how can i achieve that?
i.e example.com/{category_slug}/{blog_post_slug}

Answer 1

Should just be example.com/:category?/:slug?
Unless you skip the component all together there is no way around that. The Blog component for a post is just looking for the slug: :slug. I don't think you really have to worry about people changing the category in my opinion. Your post list page should have the url example.com/category/post for its link. Why would a user change the category?
If you really care here is a way around that. Don't use the blog post component. Make your own plugin or use CMS Pages. The code will vary slightly and in this example I will use CMS Page code cause it is 'ad hoc' and quicker.
use Rainlab\Blog\Models\Post;
function onStart() {
$category = $this->param('category');
$slug = $this->param('slug');
$posts = Post::whereHas('categories', function ($query) use ($category) {
$query->where('slug', $category);
})->get();
$this['post'] = $posts->where('slug', $slug)->first();
}
