Remove title from custom post type edit screen

Question

How can I apply the remove_post_type_support('email_template', 'title'); only for post edit screen?

The title should be available on create and not for edit.

Answer 1

You need to make small function in your function.php file:

add_action('admin_init', 'email_template_hide_title');
function email_template_hide_title() {
     remove_post_type_support('email_template', 'title');
}

I hope, It'll be help.

Answer 2

In WordPress, there is one global variable to check on which screen we are and it is global $current_screen but problem is it can not be used with admin_init action.

So alternatively we can use load-(page) action to achieve it.

add_action( 'load-post.php', 'remove_post_type_edit_screen', 10 );
function remove_post_type_edit_screen() {
    global $typenow;

    if($typenow && $typenow === 'email_template'){
        remove_post_type_support( 'email_template', 'title' );
    }
}

You can try it and give it a go.

Let me know if you have any doubt.

Explanation : If you can notice on the URL bar of the browser, then you can see when you are adding new post then it is calling post-new.php and when you are editing at that time it is calling post.php with parameters.

So we can utilize it to achieve your desired result.
