Trước đây tôi có làm một Video Series về tạo WordPress Theme, trong series lần này chúng ta sẽ học cách tạo WordPress Plugin và Widget. Tại sao chúng ta phải tạo Plugin khi mà WordPress đã có rất nhiều Plugin miễn phí?

Trong video này tôi sẽ hướng dẫn bạn những bước cơ bản nhất để tạo ra một WordPress Plugin từ vạch xuất phát.
