Add Custom Fields To A Post Using XML-RPC

The blogger.newPost method doesn’t support custom fields, but the metaWeblog.newPost method does.

I can’t work out how to do this. This is what I’ve tried but it doesn’t work. It adds the post but not the custom fields.

function wpPostXMLRPC($title,$body,$rpcurl,$username,$password,$categories=array(1)){
	$categories = implode(",", $categories);
	$XML = "<title>$title</title>".
	"<category>$categories</category>".
	$body;
	$cflds = array('name' => 'a name', 'url' => 'https://www.google.com');
	$content = array('post_type' => 'post', 'title' => $title, 'description' => $body, 'custom_fields' => $cflds);
	$params = array('',$username,$password,$content,$XML,1);
	$request = xmlrpc_encode_request('metaWeblog.newPost',$params);
	$ch = curl_init();
	curl_setopt($ch, CURLOPT_POSTFIELDS, $request);
	curl_setopt($ch, CURLOPT_URL, $rpcurl);
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
	curl_setopt($ch, CURLOPT_TIMEOUT, 1);
	curl_exec($ch);
	curl_close($ch);
	echo '<pre>'.$request;
}

Custom fields are a set of key/value pairs that look like:

"custom_fields" = (
        {key = city; value = Sacramento; },
        {key = city; value = Sandy; }
    )

Try fetching post data with metaWeblog.getPost for a post that already has custom fields and you’ll see what they look like.

That makes more sense but how would I put that in the function I have?

array(
  array( 'key' => 'city', 'value' => 'Sacramento' ),
  array( 'key' => 'city', 'value' => 'Sandy' )
)

Thank you ??

THANK YOU!

Hi, I’m using this code to post using xmlrcp but it doesn’t seem to be parsing the cusom_fields.

Any help would be much appreciated, thanks!

<?php
	include_once( 'wp-includes/class-IXR.php');

	$method_name = "wp.newPage";

	$rpc_url = "https://www.wheeloftimerp.net/xmlrpc.php";
	$blog_id    = 1;
	$username   = $_POST['reply_author'];
	$password   = $_POST['reply_password'];
	$publish    = true;    

 	$custom_fields = array(
 		"key"   => "Character",
 		"value" => $_POST['reply_character']
		);

	$post = array(
	     "title"         => $_POST['reply_title'],
	     "description"   => $_POST['reply_content'],
		 "wp_page_parent_id" =>  $_POST['reply_parent'],
		"custom_fields" => $custom_fields
	);

	$rpc = new IXR_Client( $rpc_url );
	$status = $rpc->query(
	     $method_name,
	     $blog_id,
	     $username,
	     $password,
	     $post,
	     $publish
	);

	if( !$status ) {
	     print "Error in RPC request\n";
	     print_r( $rpc );
	     exit;
	}

	print_r( $rpc->getResponse( ) );
	print "\n";

	?>

The custom fields setup should look like this:

"custom_fields" => array(
        array( "key" => "state", "value" => "Utah" ),

has anyone been able to successfully call the NewPost method with Custom Fields? I am still having no luck.

I am using a .Net Wrapper. I tried first as you all have suggested, with just key and value pairs. However, the Metablog Wrapper gives me an error that custom field ID cannot be null.

So I tried giving it a random number as ID like so (code is in C# .Net). Now the Post gets inserted, but the custom fields are getting ignored ?!

CustomField[] cf = new CustomField[1];
                cf[0].id = "354325";  //random ID number
                cf[0].key = "image_url";
                cf[0].value = "https://somesite.com/someimage.jpg";

See my example above, if all you are doing is inserting a new custom field entry you just need ‘key’ and ‘value’ since there is no ‘id’ yet. The ‘id’ field is only used when updating an existing value in some way.

I am success to call the NewPost method with Custom Fields,the demo below:

function post($result){
        include("xmlrpc.inc");
    	$GLOBALS['xmlrpc_internalencoding'] = 'UTF-8';
    	$c = new xmlrpc_client("xmlrpc.php","example.com", 80);
    	$content['title']="title";
    	$content['description']="content";
    	$content['mt_keywords']="tag1,tag2";
    	$content['wp_password']="";
    	$content['categories'] = array("label");
    	$content['custom_fields'] = array(
    	array( 'key' => 'city', 'value' => 'Sacramento' )
    	);
    	$x = new xmlrpcmsg("metaWeblog.newPost",
    	array(php_xmlrpc_encode("1"),
    	php_xmlrpc_encode("admin"),
    	php_xmlrpc_encode('841321'),
    	php_xmlrpc_encode($content),
    	php_xmlrpc_encode("1")));

    	$c->return_type = 'phpvals';
    	$r =$c->send($x);
    	if ($r->errno=="0")
    	echo "success，ID：".$r->val;
    	else {
    		echo "fail";;
    		print_r($r);
    	}
    }
