I have a text field from group One called textfield1 and I want the value of it to be copied to group Two’s textfield2.
Basically I want the value of textfield1 to be transferred to textfield2. The simplest way is to copy and paste them one by one. It’s easy if you have 10 posts but I have over 300. Is there an automated way of doing it?
Nothing easy.
You need to create a filter that runs once that gets all of the posts and then get the field and use update_field() to update the value for each post.
