WordPress –按元值按字母顺序排序帖子

Question

I have a custom post type of products, and each product belongs to a product category. I am trying to query the products to get all products sorted alphabetically by their product category ie

First :
Product: Lion
Category: Animals

Last:
Product: Snowmobile
Category: Winter

I am using a custom field for the product category, but my query doesn't sort them alphabetically - but instead by which date they are published. The product_cat_meta field is a regular text field set up in custom fields. Query is here:

function get_products()
{


  $args = array(
    'post_type' => 'products',
    'post_status' => 'publish',
    'meta_key' => 'product_cat_meta',
    'orderby' => 'meta_value',
    'order' => 'ASC',
    'posts_per_page' => -1
  );

  $products = new WP_Query($args);    
  if ($products->have_posts()) {
    $index = 0;
    while ($products->have_posts()) {
      $products->the_post();

      $prod_meta = get_field('product_cat_meta');
      echo $prod_meta;

      );
      $index++;
    } // end while
  } // end if
}

The result of this query just returns the prod category in the way they are set up in wordpress – the latest posts first, but not sorted alphabetically

Answer 1

You can try to put the code in functions.php file.

The code, which can be dropped into your current theme's functions.php if you like:

 function get_products() { $args = array( 'post_type' => 'products', 'post_status' => 'publish', 'meta_key' => 'product_cat_meta', 'orderby' => 'title', 'order' => 'ASC', 'posts_per_page' => -1 ); $products = new WP_Query($args); if ($products->have_posts()) { $index = 0; while ($products->have_posts()) { $products->the_post(); $prod_meta = get_field('product_cat_meta'); echo $prod_meta; ); $index++; } // end while } // end if }
