5 Types of Post Filters You Must Add to Your WordPress Site

There are several post filters you can add to your WordPress site to enhance the browsing experience of users. However, here are the most important ones you should consider adding to your blog:

Filter Posts By Category in WordPress

Category filters let users view posts from a specific category. For instance, a blog may have categories like "Technology," "Health," and "Travel." So, if users select the category Technology, they will only see posts within that category.

Using PostX, you can easily filter posts by category with these steps:

  • Add the Advanced Post Filter block on your selected page
  • Select the block and click on the Add Filters (+) icon from the setting toolbar

  • Choose the Category Filter from the filters list
  • Save the page and publish it

And done! Now your users should be able to filter pages based on a specific category.

Is It Possible to Filter Posts by Multiple Categories?

Yes, it is possible to filter posts by multiple categories using the plugin PostX. 

To achieve this, follow these simple steps:

  • Add the Category Filter using the Advanced Post Filter feature of PostX to your selected pages
  • Click on the Category Filter block and from the Filter Style setting choose the Inline option
filter posts by multiple categories
  • From the Filter Values dropdown, choose your preferred categories

Update or Publish the page to see the changes in effect. Your users should now be able to filter posts by multiple categories.

And that’s how easy it is to implement post filtering by more than one category with the help of PostX.

Filter Posts By Tags in WordPress

Tag filters help users find similar content through specific keywords so that they can find the posts they are interested in. Each post can have multiple tags if they represent more than one interest. 

Tags are more specific than categories. By clicking on a tag, users are able to find posts sharing a certain type of interest. So, it is particularly helpful when users need to narrow down their search to very selective topics. 

Just like category filters, PostX makes adding tag filters intuitive:

  • Click on the Add Filters (+) icon from the Advanced Post Filter block

  • Now choose the Tag Filter from the list of filters available
  • Publish or Update the page to see the changes in action

Voila! Your visitors can now start using tag filters when they are exploring blog posts. 

Is It Possible to Filter Posts by Multiple Tags?

Yes, it is possible to filter posts by multiple tags using the PostX plugin. 

The steps are quite easy to follow:

  • Enable the Advanced Post Filter feature of PostX on your selected pages and add the Tag Filter 
  • Choose the Inline option from the Filter Style setting
filter posts by multiple tags
  • Select your preferred tags from the Filter Values dropdown

Update or Publish the page and you have successfully added the functionality to filter posts by multiple tags.

Filter Posts By Attribute in WordPress

Filtering posts by different attributes such as Title, Created Date, and Date Modified is another great way to let your readers find relevant posts. 

PostX supports filtering by all of these attributes and more. 

Let’s say you want to allow users to filter posts by date. You can easily add that functionality by following these steps:

  • From the editor view of a page, select the Advanced Post Filter block and add the filter called Order By Filter
  • To control the Ascending and Descending order, also add the filter named “Order Filter (Asc/Desc)”

When you are done with the settings, Update or Publish the page.

Note: The Order By Filter is a powerful option that supports filtering based on many essential attributes. One of those attributes is the Created Date

So, following the above steps will ensure your users can easily filter posts by date. 

Users can also filter posts by some other attributes such as Date Modified, Title, Menu Order, Random, and Number of Comments. 

Filter Posts By Author in WordPress

One of the main reasons you add post filters to your WordPress site is to provide greater freedom to your users in terms of what kind of content they want to see. 

If your blog has many authors, users may want to see posts from a specific author. In such cases, adding an author filter is a must-have. 

Fortunately, PostX also offers this filter for your users. The steps to filter posts by the author are quite identical to the process for the other filters discussed in the previous sections.

Simply add the Advanced Post Filter block on a page and click on the Add Filters icon. And you will see the Author Filter option.

Add the filter to let your readers filter posts by a specific author. 

Filter Posts By Custom Taxonomy in WordPress

In the default WordPress setup, you have two taxonomies: categories and tags. These default options can become limiting when you have multiple varieties of content on your website. 

For instance, if you have a travel blog, you can set ‘Destination’ as a custom taxonomy. Your visitors can then easily find posts related to specific destinations. Based on your content, these destinations might include Europe, Asia, North America, South America, Africa, etc.

So, in such situations, you need to create custom taxonomies for Your WordPress site. And yes, you will need a plugin that supports post filtering for them.

I think you have guessed already. Yes, the Advanced Post Filter block of PostX also supports filtering with a custom taxonomy. 

Provided you have set up the custom taxonomies, here are the steps to add the filter for it:

  • After adding the Advanced Post Filter on a page, hover on its floating setting bar
  • From here, click on the Add Filters (+) icon
  • Click on the Custom Taxonomy icon to add it to the list of available filters for users

And just like that, you can successfully add all the essential filters required for your WordPress site.
