Cross-Site WordPress Content Import System

Challenge

The client needed to bring products and posts in from another site — a custom Laravel build with its own custom fields — which made a simple CSV export/import unworkable out of the box. Done manually, adding content one item at a time was slow and didn't scale as the catalog grew.

Solution

I built a cross-site import system that pulls content from a source WordPress site and creates it on the target site in bulk, with images, taxonomies and custom fields intact.

Cross-site WordPress content import from a source site to a target site in batches, keeping post types, taxonomies, fields and media

How it works

Fetches content from the source site via its REST API
Maps post types, taxonomies and custom fields between the two sites
Imports in batches, so large jobs don't time out
Downloads media once and deduplicates it on re-imports
Skips or updates items that were already imported (no duplicates)

What I built

✓Dual ingestion paths — API-based pull or CSV upload
✓Custom field mapping between the Laravel source structure and WordPress/ACF
✓One-click or one-upload imports instead of manual per-item entry
✓Planned: auto-detection of new source fields, gated behind admin confirmation before anything is created

Results

✓What used to be added one item at a time now takes a few minutes for a full batch
✓Consistent content across sites, without copy-paste errors
✓A reusable tool, not a one-off script
