Hooks on Edit Post Admin Page

There are hooks that allow you to display any content in a particular place on the admin page of adding or editing any type of post.

Thanks to hooks below, you can make the publication more convenient. All depends on your programming skills and imagination. For example:

• Place video or text right before the visual editor with tips on writing content.
• Show images already attached to the post as a slider.
• Show photos from Google by keyword so you can choose one of them for a thumbnail.
• Display a calculator for counting calories, if you publish a recipe post.
• And much more that require your certain task and allow programming skills.
