Impor post dari feed RSS WordPress

Query ini mengimpor sebuah post dari feed RSS WordPress, menggunakan judul, konten, dan kutipan dari post tersebut.

Jika penulis dengan nama pengguna tersebut ada secara lokal, maka akan digunakan; jika tidak, akan diganti dengan yang didefinisikan melalui variabel $defaultAuthorUsername.

Variabel $url menerima URL dari feed RSS post tunggal WordPress. Biasanya berupa URL post blog + "/feed/rss/?withoutcomments=1". Contoh:

https://wordpress.com/blog/2024/07/16/wordpress-6-6/feed/rss/?withoutcomments=1
