$_REQUEST['image']をURL経由で渡すことで、次のようにすることができます。 > set_post_thumbnail()、私が投稿した画像を添付した方の参考のためにそれを追加した - 投稿する画像を設定するよう

// $filename should be the path to a file in the upload directory. 
$filename = $_REQUEST['image']; 

// The ID of the post this attachment is for. 
$parent_post_id = 37; 

// Check the type of file. We'll use this as the 'post_mime_type'. 
$filetype = wp_check_filetype(basename($filename), null); 

// Get the path to the upload directory. 
$wp_upload_dir = wp_upload_dir(); 

// Prepare an array of post data for the attachment. 
$attachment = array(

// Insert the attachment. 
$attach_id = wp_insert_attachment($attachment, $filename, $parent_post_id); 

// Make sure that this file is included, as wp_generate_attachment_metadata() depends on it.

// Generate the metadata for the attachment, and update the database record. 
$attach_data = wp_generate_attachment_metadata($attach_id, $filename);
