如何从WP_Query循环中获取帖子ID？

我有一个WP_Query循环,该循环获取某种类型的帖子.这些帖子具有自定义的帖子元,因此我需要能够获取帖子的ID而不回显它,因此我可以显示该帖子的元.如何在不回显信息的情况下获取帖子的ID?这是我的代码:

 $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();可以在循环中使用.这将检索循环处理的当前帖子的ID.
  
  `$post_id = get_the_ID();` can be used within the loop. This retrieves the ID of current post handled by the loop.

- @ N00b,您应该将其发布为答案.
  
  @N00b you should post that as an answer.

- 您是要获取类别,还是要创建一个称为"类别"的自定义帖子类型?如果是前者,则应该使用[`get_categories()`](https://developer.wordpress.org/reference/functions/get_categories/)；如果是后者,则应阅读以下内容: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

只能在循环中使用

get_the_ID()(仅).

这将检索循环处理的当前帖子的ID.

如果只需要一次,则可以单独使用它:

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

如果需要多次,也可以将其存储为变量:

 $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

参考: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()

get_the_ID()函数将为您提供帖子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(

                          '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() ;
               }
            }
