WP json API-按类别获取帖子

时间：2016-03-30 作者：rgk

我在WP JSON API插件的核心控制器中添加了一个方法，该方法按类别提取帖子，但只获得一个类别数据。请在下面查找代码。

public function module_data() {

        global $json_api;

        $defaults = array(
            \'ignore_sticky_posts\' => true,
            \'category_name\' => \'food\');

        $posts = $json_api->introspector->get_posts($defaults);
        $result = $this->posts_result($posts);
        unset($result[\'pages\'], $result[\'count_total\']);
        foreach ($result[\'posts\'] as $key) {
            $key->thumbnail_image = $key->thumbnail_images[\'thumbnail\']->url;
            $key->large_image = $key->thumbnail_images[\'large\']->url;

            unset($key->id, $key->type, $key->slug, $key->url, $key->status, $key->title_plain, $key->excerpt, $key->categories, $key->tags, $key->author, $key->comments, $key->custom_fields, $key->comment_status, $key->comment_count, $key->attachments, $key->date, $key->modified, $key->thumbnail, $key->thumbnail_size
                    , $key->thumbnail_images[\'full\'], $key->thumbnail_images[\'medium\'], $key->thumbnail_images[\'medium_large\'], $key->thumbnail_images);
        }
        $res[\'food\'] = array_reverse($result[\'posts\']);           


        $defaults_two = array(
            \'ignore_sticky_posts\' => true,
            \'category_name\' => \'history\');

        $posts_two = $json_api->introspector->get_posts($defaults_two);
        $result_two = $this->posts_result($posts_two);
        unset($result_two[\'pages\'], $result_two[\'count_total\']);
        foreach ($result_two[\'posts\'] as $key) {
            $key->thumbnail_image = $key->thumbnail_images[\'thumbnail\']->url;
            $key->large_image = $key->thumbnail_images[\'large\']->url;

            unset($key->id, $key->type, $key->slug, $key->url, $key->status, $key->title_plain, $key->excerpt, $key->categories, $key->tags, $key->author, $key->comments, $key->custom_fields, $key->comment_status, $key->comment_count, $key->attachments, $key->date, $key->modified, $key->thumbnail, $key->thumbnail_size
                    , $key->thumbnail_images[\'full\'], $key->thumbnail_images[\'medium\'], $key->thumbnail_images[\'medium_large\'], $key->thumbnail_images);
        }

        $res[\'history\'] = array_reverse($result_two[\'posts\']);

        return $res;
    }
输出：

我用另一种方式解决了这个问题。首先，我通过在其中包含类别名称来提取所有帖子。检查下面的答案。

public function module_data() {
        global $json_api;
        $url = parse_url($_SERVER[\'REQUEST_URI\']);
        $defaults = array(
            \'ignore_sticky_posts\' => true,
            \'posts_per_page\' => -1,
            \'order_by\' => \'date\',
            \'order\' => \'ASC\'
        );
        $query = wp_parse_args($url[\'query\']);
        unset($query[\'json\']);
        unset($query[\'post_status\']);
        $query = array_merge($defaults, $query);
        $posts = $json_api->introspector->get_posts($query);
        $result = $this->posts_result($posts);
        unset($result[\'pages\'], $result[\'count_total\']);
        foreach ($result[\'posts\'] as $key) {
            $key->thumbnail_image = $key->thumbnail_images[\'thumbnail\']->url;
            $key->large_image = $key->thumbnail_images[\'large\']->url;
            $key->category = $key->categories[0]->title;
            //$key->categories
            unset($key->id, $key->type, $key->slug, $key->url, $key->status, $key->title_plain, $key->excerpt, $key->tags, $key->author, $key->comments, $key->custom_fields, $key->comment_status, $key->comment_count, $key->categories, $key->attachments, $key->date, $key->modified, $key->thumbnail, $key->thumbnail_size
                    , $key->thumbnail_images[\'full\'], $key->thumbnail_images[\'medium\'], $key->thumbnail_images[\'medium_large\'], $key->thumbnail_images);
        }
        $result[\'posts\'] = $result[\'posts\'];

        return $result;
    }
