Wordpress數據爲JSON

Question

下面的代碼用於打印Wordpress網站上Woocommerce產品的一些數據。

<?php 
    $args = array(
       'post_type' => 'product', 
       'posts_per_page' => 200, 
       'product_cat' =>'pants' 
      ); 
    $loop = new WP_Query($args); 

    while ($loop->have_posts()) : $loop->the_post(); 
    global $product; 


    echo '<br /><a href="'.get_permalink().'">' . woocommerce_get_product_thumbnail().' '.the_title(). ' '.the_content().' '.get_post_meta(get_the_ID(), '_regular_price', true).' '.get_post_meta(get_the_ID(), '_sale_price', true).'</a>'; 
    endwhile; 
    wp_reset_query(); 
?> 

這得到我需要的產品，如他們的名字，圖像，章的數據。價格和銷售價格等。此代碼成功完成並將數據回顯到頁面上。該代碼將在每個產品上返回這些數據，以便將具有其名稱，圖像等的產品列表打印到html頁面上。

但是，我需要獲取與此代碼檢索相同的數據，但使用JSON格式。

許多產品將與每一個JSON對象格式返回：

[{"term_id":"64","name":"Argentina","slug":"argentina","term_group":"0","term_taxonomy_id":"64","taxonomy":"product_cat","description":"","parent":"13","count":"20","meta_id":"154","woocommerce_term_id":"64","meta_key":"order","meta_value":"0","cat_ID":"64","category_count":"20","category_description":"","cat_name":"Argentina","category_nicename":"argentina","category_parent":"13"},] 

的JSON當我做這個echo json_encode($loop->get_posts());

我怎麼是呼應了同樣的數據上面返回到以JSON而不是HTML格式返回的頁面上。

請幫忙。我一直在尋找這個答案。

這是不可能的嗎？沒有人似乎有答案。任何幫助，將不勝感激。

編輯：

當我做echo json_encode($loop);，我得到如下：

改變你的代碼，同時循環與此

$jsondata = array(); 
while ($loop->have_posts()) : $loop->the_post(); 
global $product; 

$jsondata[] = array(
    'image' =>woocommerce_get_product_thumbnail(), 
    'title' => get_the_title(), 
    'content' => get_the_content(), 
    'regular_price' => get_post_meta(get_the_ID(), '_regular_price', true), 
    'sale_price'=> get_post_meta(get_the_ID(), '_sale_price', true) 
); 
endwhile; 
wp_reset_query(); 

ob_clean(); 
echo json_encode($jsondata); 
exit();
