Eutenho um loop WP_Query que recebeposts de um determinadotipo. Essaspostagenstêmmeta depostpersonalizada,entãoeupreciso ser capaz de obter oid dopost semecoarpara queeupossaexibiressameta dopost. Comoposso obter oid dopost semecoar? Este é omeu código:

 $menu_id = get_the_id();
        $category_args = array(
            'post_type' => 'category',
            'post_parent' => $menu_id
        );

        $menu_categories = new WP_Query($category_args);
        while($menu_categories->have_posts()) : $menu_categories->the_post(); 
            $category_id = ??????; ?>
        <h4><?php echo the_title(); ?></h4><?php 

            $dish_args = array(
                'post_type' => 'dish',
                'post_parent' => $category_id
            );
            $category_dishes = new WP_Query($dish_args);
            while($category_dishes->have_posts()) : $category_dishes->the_post(); 
                $dish_meta = get_post_meta(???????);?>
            <h6><?php echo the_title(); ?> - <?php echo $dish_meta[0]['price']; ?></h6>
            <p><?php echo the_content(); ?></p><?php
            endwhile;
        endwhile;

I have a WP_Query loop that gets posts of a certain type. These posts have custom post meta so I need to be able to get the ID of the post without echoing it so I can display that post's meta. How can I get the ID of the post without echoing it? This is my code:

$menu_id = get_the_id();
        $category_args = array(
            'post_type' => 'category',
            'post_parent' => $menu_id
        );

        $menu_categories = new WP_Query($category_args);
        while($menu_categories->have_posts()) : $menu_categories->the_post(); 
            $category_id = ??????; ?>
        <h4><?php echo the_title(); ?></h4><?php 

            $dish_args = array(
                'post_type' => 'dish',
                'post_parent' => $category_id
            );
            $category_dishes = new WP_Query($dish_args);
            while($category_dishes->have_posts()) : $category_dishes->the_post(); 
                $dish_meta = get_post_meta(???????);?>
            <h6><?php echo the_title(); ?> - <?php echo $dish_meta[0]['price']; ?></h6>
            <p><?php echo the_content(); ?></p><?php
            endwhile;
        endwhile;

- `$post_id=get_the_id ();`pode ser usado dentro do loop.Isso recupera o ID dopost atualmanipuladopelo loop.
  
  `$post_id = get_the_ID();` can be used within the loop. This retrieves the ID of current post handled by the loop.

- Vocêestátentando obter categorias outer umtipo depostpersonalizado chamado "Categoria"?Se oprimeiro,então você deveestar usando ['get_categories () `] (https://developer.wordpress.org/reference/functions/get_categories/) Se o último,então você deve leristo: https://codex.wordpress.org/reserved_terms.
  
  Are you trying to get categories, or have you a custom post type called "category"? If the former then you should be using [`get_categories()`](https://developer.wordpress.org/reference/functions/get_categories/) if the latter then you should read this: https://codex.wordpress.org/Reserved_Terms

get_the_ID()pode (apenas) ser usado dentro do loop.

Isso recupera o ID dapostagem atualmanipuladapelo loop.

Vocêpode usá-loem seupróprio se vocêprecisar apenas uma vez:

 $dish_meta = get_post_meta( get_the_ID(), 'dish_meta', true );

Vocêtambémpode armazená-lo como uma variável se vocêprecisarmais de uma vez:

 $post_id = get_the_ID();

$dish_meta = get_post_meta( $post_id, 'dish_meta', true );

$drink_meta = get_post_meta( $post_id, 'drink_meta', true );

print_r( $post_id );

//etc

Referência: get_the_id ()

get_the_ID() can (only) be used within the loop.

This retrieves the ID of the current post handled by the loop.

You can use it on it's own if you need it only once:

$dish_meta = get_post_meta( get_the_ID(), 'dish_meta', true );

You can also store it as a variable if you need it more than once:

$post_id = get_the_ID();

$dish_meta = get_post_meta( $post_id, 'dish_meta', true );

$drink_meta = get_post_meta( $post_id, 'drink_meta', true );

print_r( $post_id );

//etc

Reference: get_the_ID()

             $args = array(

                          's' => $_POST['search_text'],
                          'posts_per_page' => -1,
                          'post_type' => 'address'

                     );

            $query = new WP_Query( $args );

            if ( $query->have_posts() ) {

               while ( $query->have_posts() ) {

                    $query->the_post();

                    $address_post_id = get_the_ID() ;
               }
            }

get_the_ID() function will give you post ID..,

            $args = array(

                          'post_type' => 'address'

                     );

            $query = new WP_Query( $args );

            if ( $query->have_posts() ) {

               while ( $query->have_posts() ) {

                    $query->the_post();

                    $address_post_id = get_the_ID() ;
               }
            }
