The official Wordpress documentation can be found here.

WordPress auto insert post_id in the post_title for a cpt

I’m looking for the snippet code to allow me to automatically insert the post_id for each new post in wordpress (CPT "property")

the reason: I have several posts with the same style of title like
"hello world" for example

if I have 10 posts with hello world .. how to differentiate them in the post_title?

I don’t know if this kind of code snippet exists
but it will save me a lot of time to copy / paste

"hello world – id 2140"

"hello world – id 2141"

"hello world – id 2142"

new post >
(your post name here) – id 2143

if you have an idea please share

enter image description here

EDIT :

I found this post which talks about the same thing.

it seems like it’s…not really possible

because post_id is generated when I click on publish

how could it display an id to a new post when it’s not yet generated?
I think I will still have long copy/paste days to come…

    You can do it with a simple sql:

    UPDATE wp_posts set post_name = concat(post_name, ' - id ', id) where UPPER(post_name) = 'HELLO WORLD';

    To display the ID after the title of each post you can edit the templates of your theme, for example the index.php file, the single.php file, page.php etc. and add echo get_the_ID(); right after the_title() in the PHP code of those templates.

    BTW: I’d create a child theme in this case because any theme update will overwrite those template files. (see https://developer.wordpress.org/themes/advanced-topics/child-themes/ for more on that subject)

    You’re probably looking for some function hooked to save_post.

    As of WP 3.7, an alternative to the save_post action has been introduced, which is called for specific post types: save_post_{post_type}. In your case we can use the save_post_property hook to intercept the post title and apply changes to it (where property refers to the dynamic part _{post_type}).
    Hooking to this action prevents your callback to be unnecessarily triggered. It fires once a post has been saved (like save_post).

    We need to discard any updates, autosaves or revisions actions. The WordPress autosave system fire every 60 seconds.

    The $update parameter from save_post_{post_type} is supposed to determined whether this is an existing post being updated. It applies more specifically to a post autosave revision. The $update parameter will always be true when firing through wp_publish_post. But that isn’t true for its usage in wp_insert_post.

    In our case, the wp_publish_post function publish a post by transitioning the post status.

    By additionally crosschecking the post status we can effectively determine whether it is indeed a non-existing post.

    A few more things: If you are calling a function such as wp_update_post that includes the save_post hook, your hooked function will create an infinite loop. To avoid this, unhook your function before calling the function you need, then re-hook it afterward.

    save_post_{post_type} will fire on post update (eg: autosave) or publish which is why we’re running into an infinite loop.

    <?php

add_action( 'save_post_property', function ( $post_id, $post, $update ) {

    if ( ! wp_is_post_autosave( $post_id ) && ! wp_is_post_revision( $post_id ) && ! $update && $post->post_status == 'auto-draft' ) {

        $title = $post->post_title;
        $title .= ' - ID ';
        $title .= $post_id;

        $slug = sanitize_title( $title );

        remove_action( 'save_post_question', array( $this, 'automatically_generate_the_custom_post_type_question_title' ), 10, 3 );
                    
        wp_update_post( array(
            'ID' => $post_id,
            'post_title' => $self,
            'post_name' => $slug,
        ) );
                    
        add_action( 'save_post_question', array( $this, 'automatically_generate_the_custom_post_type_question_title' ), 10, 3 );

    };

}, 10, 3 );
