多说中有个较为实用的功能——“同时发布到”，只需要绑定新浪微博、腾讯微博、百度……只需勾选编辑文章页上的选项，一键搞定。如果我们需要在主题中集成此功能呢？方法来自发哥，感谢分享。

syncweibo

实现方法：

把下面的代码加到 functions.php 中，注意添加access_token 和默认图片地址两个参数，access_token 的获得方法参考相关文章（比如说 CNBlogs）。

class sync_sina {
 
    public $access_token = "";//access_token
    
    public $default_image = "";//默认图片地址
 
    public $host = "https://api.weibo.com/2/";
       
    public static $boundary = '';
       
    function __construct(){
        /**
         ** 事件绑定
         **/
        add_action('publish_post', array($this, 'new_post_photo'));
    }
 
    function do_mu_post($url, $data) {
        $ch = curl_init ();
        $headers = array("Content-Type:multipart/form-data;boundary=". self::$boundary);
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, TRUE );
        curl_setopt ( $ch, CURLOPT_POST, TRUE );
        curl_setopt ( $ch, CURLOPT_POSTFIELDS, $data );
        curl_setopt ( $ch, CURLOPT_URL, $url );
        curl_setopt ( $ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        $ret = curl_exec ( $ch );
        curl_close ( $ch );
        return $ret;
    }

        if (!$params) return '';
