Attach image to post in WordPress XMLRPC

3 comments

1. Yes it is possible to do it, if WordPress version is 3.5 or greater,when using the code for uploading file/image you can set the post_id.
   The flow I used for new posts with featured images is like this:

   1. use the newPost function and post the content without the featured
      image and also set publish to false, record the post_id returned by
      this

   2. upload the image and set the post_id to the id of the post just
      posted, record the image_id

   3. when done edit the post and set the wp_post_thumbnail equal to the
      image_id you just uploaded and also set publish to true(if needed)

   Important:
   The mime type is important, it must be “image/jpg” or “image/png” please see documentation, if mime type is worng like “jpg” attaching will fail.

   Tip:
   For debugging, if you get a generic error from wordpress and you can’t figure out why you can check the wordpress code and even edit it, adding debugging/tracing calls and hopefully you can figure out the cause.

   This is an example of a post with category, image and tags. It requires class-IXR.php
   https://github.com/WordPress/WordPress/blob/master/wp-includes/class-IXR.php
   and mime_content_type function
   https://github.com/caiofior/storebaby/blob/master/magmi/plugins/extra/general/socialnotify/wp/mimetype.php

           $client = new IXR_Client($url);
           $content = array(
               'post_status' => 'draft',
               'post_type' => 'post',
               'post_title' => 'Title',
               'post_content' => 'Message',
                // categories ids
               'terms' => array('category' => array(3))
           );
           $params = array(0, $username, $password, $content);
           $client->query('wp.newPost', $params);
           $post_id = $client->getResponse();
   
           $content = array(
               'name' => basename('/var/www/sb/img.jpeg'),
               'type' => mime_content_type('/var/www/sb/img.jpeg'),
               'bits' => new IXR_Base64(file_get_contents('/var/www/sb/img.jpeg')),
               true
           );
           $client->query('metaWeblog.newMediaObject', 1, $username, $password, $content);
           $media = $client->getResponse();
           $content = array(
               'post_status' => 'publish',
               // Tags
               'mt_keywords' => 'tag1, tag2, tag3',
               'wp_post_thumbnail' => $media['id']
           );
           $client->query('metaWeblog.editPost', $post_id, $username, $password, $content, true);

2. My version if you want to use only wp.newPost and wp.editPost

3. This is my version, using wp.newPost and wp.editPost, added on WordPress 3.4, that allow the use of custom post types.

   require_once("IXR_Library.php.inc");
   $title = 'My title';
   $body = 'My body';
   $category="category1, category2"; // Comma seperated pre existing categories. Ensure that these categories exists in your blog.
   $keywords="keyword1, keyword2, keyword3";
   $customfields=array('key'=>'Author-bio', 'value'=>'Autor Bio Here'); // Insert your custom values like this in Key, Value format
   
   $title = htmlentities($title,ENT_NOQUOTES,@$encoding);
   $keywords = htmlentities($keywords,ENT_NOQUOTES,@$encoding);
   
   $content = array(
       'post_title'=>$title,
       'post_content'=>$body,
       'post_type'=>'some_custom_post_type',
       'post_status' => 'draft', // http://codex.wordpress.org/Post_Status
       'mt_allow_comments'=>0, // 1 to allow comments
       'mt_allow_pings'=>0, // 1 to allow trackbacks
       'mt_keywords'=>$keywords,
       'categories'=>array($category),
       'custom_fields' => array($customfields)
   );
   
   // Create the client object
   $client = new IXR_Client('http://example.com/xmlrpc.php');
   $username = "wp_username";
   $password = "wp_username_password";
   
   $params = array(0,$username,$password,$content,true); // Last parameter is 'true' which means post immediately, to save as draft set it as 'false'
   
   if (!$client->query('wp.newPost', $params)) {
       die('<br/><strong>Something went wrong - '.$client->getErrorCode().' : '.$client->getErrorMessage().'<br >');
   
       }
   else
   {   
       $post_id = $client->getResponse();
       echo 'Inserted with id'.$post_id;
       $picture = '/full/path/to/pic.jpg';
       $content = array(
           'name' => basename($picture),
           'type' => mime_content_type($picture),
           'bits' => new IXR_Base64(file_get_contents($picture)),
           true
       );
       if (!$client->query('metaWeblog.newMediaObject', 1, $username, $password, $content)) {
           die('<br/><strong>Something went wrong - newMediaObject'.$client->getErrorCode().' : '.$client->getErrorMessage().'<br >');
       }
       else
       {
           $media = $client->getResponse();
           $content = array(
               'post_status' => 'publish',
               'post_thumbnail' => $media['id']
           );
           if (!$client->query('wp.editPost', 0, $username, $password,  $post_id, $content)) {
               die('<br/><strong>Something went wrong editPost - '.$client->getErrorCode().' : '.$client->getErrorMessage().'<br >');
