Is there a way to set default custom fields when creating a new post?

Question

When I'm creating a new post, just after clicking "Add New", when the post editor shows, instead of having to use the dropdown and choose a custom field to use, I'd like to have some default custom field inputs already opened.

None of the codes from here worked for me

Answer 1

you can do that better with install advanced custom fileds plugins or any plugin and specify the custom field to all posts , you can install this plugin

or by your simple codes in wordpress and choose one
