I want to add a button in Add New Page and Add New Post pages.
Here are places I want to add items:
- New page's sidebar (next to Page Attributes).
New post's sidebar (next to Post Attributes).
New page's top bar (next to Block Navigation).
- New post's sidebar (next to Block Navigation).
What are the action hook to do it so?
function add_new_button_function (???)
{
echo "some html code";
}
add_action( '???', 'add_new_button_function' );
