18310,Attachments inserted with NULL value for GUID,docfish,,"This is the error I get when trying to post via xml-rpc interface:

Empty delimiter in .../wp-includes/class-wp-xmlrpc-server.php on line 2469 Warning:  Cannot modify header information - headers already sent by (output started at .../wp-includes/class-wp-xmlrpc-server.php:2469) in .../webraces/wp-includes/class-IXR.php on line 471

The line 2469 of class-wp-xmlrpc-server.php looks like:

if ( strpos( $post_content, $file->guid ) !== false )

Apparently $file->guid has invalid value as this is fixed by inserting

if($file->guid && !($file->guid == NULL))

right above the line in question. See also http://wordpress.org/support/topic/windows-live-writer-no-go-with-wp-312",defect (bug),new,normal,3.6,XML-RPC,3.2.1,normal,,has-patch mobile commit dev-feedback,ian_dunn@… koke
