Ho un ciclo WP_Query che ricevepost di un certotipo. Questipost hanno unmetapostpersonalizzato,quindi devoesserein grado di ottenere l'ID delpost senzafarloecoin modo dapoter visualizzareilmeta di quelpost. Comeposso ottenere l'ID delmessaggio senza visualizzarlo? Questo èilmio codice:

 $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 ();"puòessere utilizzato all'interno del ciclo.Questo recupera l'ID delpost correntegestito dal loop.
  
  `$post_id = get_the_ID();` can be used within the loop. This retrieves the ID of current post handled by the loop.

- Stai cercando di ottenere categorie o hai untipo dipostpersonalizzato chiamato "categoria"?Nelprimo caso dovresti usare [`get_categories ()`] (https://developer.wordpress.org/reference/functions/get_categories/) seil secondo dovresti leggere questo: 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()può (solo) essere utilizzato all'interno del ciclo.

Questo recupera l 'ID delpost correntegestito dal loop.

Puoi usarlo da solo sene haibisogno solo una volta:

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

Puoi anchememorizzarlo come variabile sene haibisognopiù di una volta:

 $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

Riferimento: 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()

Lafunzioneget_the_ID ()ti darà l'ID delpost ..,

             $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(

                          '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() ;
               }
            }
