$now_id=get_the_ID(); 
$now_post=get_post($now_id); 
$now_content=$now_post->post_content; 

/*

  */ 
  $now_id=get_the_ID(); 
  $now_post=get_post($now_id); 
  $now_content=$now_post->post_content; 

  $content_json=json_decode($now_content,true); 
  //print_r($content_json); 
  $text_title=$content_json["title"]; 
  $text_small=$content_json["title-small"]; 
  $category_text=$content_json["category"]; 
  $args = array( 
      'post_type' => 'post', 
      'showposts' => 8, 
      "category_name"=>$category_text, 
      'orderby' => 'date', 
      'paged'    => $paged, 
  ); 
  $loop = new WP_Query($args); 

查询说明

$args = array( 
           'post_type' => 'post', 
           'showposts' => 8, 
           "category_name"=>$category_text, 
           'orderby' => 'date', 
           'paged'    => $paged, 
       ); 

post_type为查询类型category_name为文章的别名

剩下的看API即可..以后会逐步更新
