Step-by-Step to Create Job Listings CPT with Complex Taxonomy Structure in WordPress [Case Study]

In developing a job portal website, I faced the challenge of creating a flexible and manageable Job Listings CPT System. WordPress default post types were not sufficient for job portal needs requiring multiple criteria like location, education, experience, and job type. I decided to create a custom post type ‘lowongan’ with a complex taxonomy structure and advanced filtering system.

As an Example

• Before: Default WordPress posts with simple categories
• After: Custom post type ‘lowongan’ with 6 custom taxonomies and advanced filtering
• Result: Powerful, manageable, and user-friendly job portal
