function Wp_get_attachment_url ($post _id = 0) {$file _dir=dirname (__file__); $server _root=$_server[document_root];$ File_dir=substr ($file _dir,strlen ($server _root)), $file _dir=substr ($file _dir,0,-12), if ($file _dir!= ") {$file _dir= ' /'. substr ($file _dir,1);} $post _id = (int) $post _id;if (! $post =& get_post ($post _id)) return false; $url = "; if ($file = Get_post_meta ($post ->id, ' _wp_attached_file ', true)) {//get attached fileif (($uploads = Wp_upload_dir ()) && false = = = $uploads [' ERROR ']) {//get upload directoryif (0 = = = Strpos ($file, $uploads [' Basedir ']))//check that the upload base exists in the file lo cation//$url = str_replace ($uploads [' Basedir '], $uploads [' BaseURL '], $file); Replace file location with URL location$url= $file _dir. " /wp-content/uploads/". $file; ElseIf (False!== Strpos ($file, ' wp-content/uploads '))//$url = $uploads [' BaseURL ']. substr ($file, Strpos ($file, ' wp-content/uploads ') + +); $url = $file _dir. " /wp-content/uploads/". $file; else//$url = $uploads ['BaseURL ']. "/$file"; Its a newly uploaded file, therefor $file are relative to the basedir. $url = $file _dir. " /wp-content/uploads/". $file;}}  if (empty ($url))//if any of the above options failed, Fallback on the GUID as used pre-2.7, not recomended to rely upon this. $url = Get_the_guid ($post->id), if (' attachment '! = $post->post_type | | empty ($url)) return False;return app Ly_filters (' Wp_get_attachment_url ', $url, $post->id);}
