ACF get_field() is not returning a value in WordPress

Question

I am using ACF and CPT cooperatively. I created a shortcode to be placed in a text module in my theme. It works well. Yet, when I call ACF get_field(), it's not returning any value. I tried looking into this question and also this one, but neither works.

I double-checked ACF fields name. Also tried to change the input type from text to number but still no hope.

Development Environment

• WordPress Version: 5.2.2 (Latest at the moment)
• Theme/Child Theme Version: Divi 3.25.3

The shortcode I created:

  <?php
    add_shortcode('RESTAURANT_MENU', 'fetch_menu_products');
    function fetch_menu_products($atts)
    {
      $atts = shortcode_atts(array(
        'category_name' => ''
      ), $atts);
      $category_name = $atts['category_name'];

      $args = array(
        'category_name' => $category_name,
        'post_type' => 'menu',
        'numberposts' => -1,
        'post_status' => 'publish'
      );

      $output = '';
      $menu_products = get_posts($args);
      foreach ($menu_products as $menu_product) {
        setup_postdata($menu_product);
        $output .= '<section class="menu-item-wrapper">';
        $output .= '<h3 class="menu-item__title">' . $menu_product->post_title . '</h3>';
        $output .= '<div class="menu-item">';
        $output .= '<div class="menu-item-description">';
        $output .= '<p class="menu-item-description__text">' . $menu_product->post_content . '</p>';
        $output .= '</div>';
        $output .= '<ul class="menu-prices-list">';
        if (get_field("regular_size_price") || get_field("large_size_price")) {
          $output .= '<li class="menu-prices-list--item">R ' . get_field("regular_size_price", $menu_product->ID)  . ' Currency</li>';
          $output .= '<li class="menu-prices-list--item">L ' . get_field("large_size_price", $menu_product->ID) . ' Currency</li>';
        }
        if (get_field("price")) {
          $output .= '<li class="menu-prices-list--item">' . get_field("price", $menu_product->ID)  . ' Currency</li>';
        }
        $output .= '</ul>';
        $output .= '</div>';
        $output .= '</section>';
      }
      wp_reset_postdata();
      return $output;
    }

Can any help me find out why isn't it returning any value, please? Thank you.

Update: The ACF Location Rules

Answer 1

Try to use get_post_meta() instead of get_field(). As you are already using ACF then use this code to get value from post meta

get_post_meta($menu_product->ID, 'regular_size_price')[0]
