J'ai uneboucle WP_Query qui récupère lesmessages d'un certaintype. Cespublications ont uneméta depublicationpersonnalisée,je dois donc êtreen mesure d'obtenir l'ID de lapublication sans l'écho afin depouvoir afficher laméta de cettepublication. Commentpuis-je obtenir l'ID de lapublication sans yfaire écho? Voicimon 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;

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 ();`peut être utilisé dans laboucle.Cela récupère l'ID de lapublication actuellegéréepar laboucle.
  
  `$post_id = get_the_ID();` can be used within the loop. This retrieves the ID of current post handled by the loop.

- Essayez-vous d'obtenir des catégories ou avez-vous untype depublicationpersonnalisé appelé «catégorie»?Si lepremier,vous devriez utiliser [`get_categories ()`] (https://developer.wordpress.org/reference/functions/get_categories/) si le second,vous devriez lire ceci: 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()peut (seulement) être utilisé dans laboucle.

Ceci récupère l 'ID dumessage actuelgérépar laboucle.

Vouspouvez l'utiliser seul si vousn'en avezbesoin qu'une seulefois:

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

Vouspouvez également le stockeren tant que variable si vousen avezbesoinplusieursfois:

 $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

Référence: 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()

Lafonction

get_the_ID () vous donnera l'identifiant de l'article ..,

             $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() ;
               }
            }
