Hay Guys, pada Artikel kali ini Mangcoding akan membagikan cara untuk duplikasi Halaman atau Post website Anda. Langkah ini sangat berguna bagi Anda untuk menggandakan postingan, halaman WordPress dan mempermudah pekerjaan Anda jika bekerja dengan banyak postingan serupa. Apalagi jika postingan memiliki nilai custom Field yang sama.
Ini berarti Anda tidak harus melakukan input post, tag pos dan kategori secara berulang kali, Silahkan perhatikan Gambar dibawah ini!
Ini cukup mudah dilakukan, jadi, lihat kode berikut, masukkan ke dalam functions.php file Anda saat ini atau tema anak atau plugin kustom Anda sendiri.

Dari kode diatas, Kita dapat mengambil kesimpulan :
- Jika Anda hanya tertarik pada cara menduplikat halaman di WordPress tanpa plugin, Anda cukup menggunakan page_row_actionsfilter hook (baris 11), jika Anda tertarik untuk menduplikasi posting, Anda cukup menggunakan post_row_actionscocok (baris 9 ).
- Dalam kode, Anda dapat menemukan beberapa pemeriksaan keamanan, saya menggunakan Nonce dan menghapus $_GET[ ‘post’ ]dengan absint()fungsi.
- Pada baris 71-85 Anda dapat mengubah data posting untuk kebutuhan Anda. Misalnya ingin menduplikasi postingan sebagai draf, tetapi Anda dapat mengatur publish status postingannya.
