Trending Posts

Collections 

​

For this example we used the database collections automatically added to your site if you have a blog:

• Blog/Posts collection: Contains information about your individual blog posts

• Blog/Categories collection: Contains information about your blog categories

Page Elements

​

In our site we added the following page elements:

• Strip: Custom header strip for a repeater element. 

• Trending repeater with the following items:

  • Text: Post title

  • Image: Post image

  • Text: Number of “Likes,” converted to text

  • Text: Number of views, converted to text

  • Link: Post URL

Code

​

1. Set variables for:

   • likesWeight and viewsWeight: The weight percentages for likes and views. Use these percentages to calculate if a post is trending. 

   • trendingPostsToShow: How many trending posts to display on the page.

2. When the page is ready, call the loadTrendingPosts() function which holds the core functionality for displaying which posts are trending.

3. Query the Blog/Posts collection to retrieve all blog posts. 

4. Calculate the “trending strength” of each blog post  and store the calculations along with each post in a trendingPosts array.

5. Sort the trendingPosts array.

Display a certain number of posts, as set with the trendingPostsToShow variable.
