C++: Allocate two arrays of same size but different types in a single allocation

Does the standard library offer a way to allocate two arrays of different member types, but with the same size in a single allocation?

I am trying to figure out a solution that

  • doesn’t require calculating the overall size manually while respecting alignment requirements,
  • ideally has memory management covered, i.e. doesn’t require freeing memory manually.
  • compiles with clang and MSVC (ideally portable :-))

Essentially, something like

    struct {
        A as(n);
        B bs(n);
    } arrays;

Where n is dynamic.

custom post types – restrict content for users with same role

I have created a custom post type (CPT) called “books” where users will be able to exchange “bookid” and “bookinfo” (as ACF).

I have created user roles such as Countries and cities (France> Paris, France>Marseille)

I am looking to find a way that a user who has the user role Paris can only “view/edit/delete” the books from all users from same user role (Paris)

I am also looking to find a way that a user who has the user role France will be able to “view/edit/delete” the books from all sub user roles such as Paris and Marseille.

I hope my idea is quite clear…
I havent found any plugin who could do that or any function after hours of research online.
any idea ?

custom post types – How to get rewrited name of cusom taxonomy?

I have registered custom post taxonomy with rewrited name:

register_taxonomy('behold_gallery-albums-subject', 'behold_gallery',array(
    'hierarchical'              => true,
    'labels'                    => $labels,
    'show_ui'                   => true,
    'show_admin_column'         => true,
    'rewrite'                   => array( 'slug' => 'kategorie-galerii', 'with_front' => true ),
    'update_count_callback'     => '_update_post_term_count',
    'query_var'                 => true,

so name of my custom taxonomy is ‘behold_gallery-albums-subject’ but is rewrited to ‘kategorie-galerii’.

If I want to get name of this taxonomy, I can use this

$postsTaxonomy = get_sub_field('archive__post-choose-taxonomy'); // ACF
$postsTerm = get_term_by( 'slug', get_query_var( 'term' ), get_query_var( 'taxonomy' ) ); 
$postsTerm_id = $postsTerm->term_id;
$PostsTaxName = get_taxonomy($postsTaxonomy)->labels->name;

but how can I get this rewrited name, not the ‘original’?


Button per line in Custom Post Types

Since several hours ago I am trying to solve this issue but I don’t know what I am doing wrong in the code.

I have a Custom Post Type with several records, then I wrote a php script to show the content as a table:

Query Table

At the end of each row there is a button, the idea is to pass the row’s POST_ID value to other form and php script. However, after you click this button, it opens a new tab with the URL including the name of the site and Post_id value like https://telework/wp-admin/admin.php?Id=2749&submit_btn=Pagar.

The button’s code is:

<td> <form type="post"><input type="hidden" name="Id" value="<?php echo $post_id; ?>"><input type="submit" name="submit_btn" value="Pagar"></form></td>

I’ve tried to insert action=”process.php” inside <form>, then change the type=”post” to method=”post” but gives me error 500.
How and where can I include the code to open the new form and php script?
Thank you for your help and have a good day.

typescript – Typescrip no react, instalação com @types

Estou querendo instalar uma biblioteca que insere um input do estilo time, na seguinte instalação

npm install react-time-picker

E para instalar o typescript seria o

npm install @types/react-time-picker

So que da o seguinte erro

npm ERR! 404 Not Found – GET https://registry.npmjs.org/@types%2freact-time-picker – Not found
npm ERR! 404
npm ERR! 404 ‘@types/react-time-picker@latest’ is not in the npm registry.

npm ERR! 404
npm ERR! 404 Note that you can also install from a

Pelo que entendi isso significa que não existe o types dessa biblioteca?
Se sim, existe alguma solução?
