Which one is better to create an image uploader for posts and pages? meta_box or custom_field?
I created an image uploader for a settings page that I just created to my site. I used register_setting to do that.
I already created an image uploader for posts as banner. The Image uploader is created using a plugin named ACF(advanced custom fileds). I want to create a custom image uploader from scratch without any plugin. I am really confused how to do it. Should I use add_meta_box() or register_setting()? or maybe custom fields? I am new to WordPress. Please someone tell me the best approach and if possible how to do it.
Thank all of you in advance.
