How to Create Admin FIlters for the Custom Post Type

This filter type helps the admin to sort posts by taxonomy assigned to the needed Custom Post Type. Follow this tutorial to learn more about How to Create a Custom Taxonomy.

For example, there is a “Room” post type, and we need to filter rooms by the “Room Types” taxonomy. 

Once the Admin tab in the Custom Post Type is opened, set the Name/Placeholder for a filter and select the “Filter by Taxonomy” option in the Type dropdown. Then, don’t forget to pick the needed Taxonomy by which posts will be filtered.

To change the categories display order in the filters, enable the Show Counts feature and set the “From highest to lowest values” Order.

Glossary option source

Firstly, create a filter with the “Filter by meta data” Type.

Now to filter by specific meta field, select it from the list.
To pull the labels from the glossary, choose the samely named item in the Options Source drop-down and pick the needed glossary from the Glossary list.

In the following picture, you may see configured admin filter:

Save the changes and check the results.

Field options source

Now we will create another admin filter, but the “Select from database” or “Field options” configuration will be used in the current case. It depends on the meta field type.

This option pulls the value out of the meta field from each post that has a value inside the selected field.

In this example, a filter is by the text field, which shows a cost for a specific room according to the Custom Meta Field key.

The same result can be achieved by selecting the exact meta field from the list. You may see the configuration in the picture below.

In this case, we should choose the “Select from database” Options Source. This option can be different depending on the meta field type you will use.

Now let’s check the result.

To create this filter type, you should create a relation first. Please follow the How to Create Relationships Between Posts tutorial. 

Now we will create a filter for “Orders” Custom Post Type by related “Room” posts. 

Select the needed filter Type and choose the Relation by which posts will be filtered.

Save the changes and check the results.
