Здравствуйте!
Знакомый написал небольшой рнр скрипт, который при выборе файлов из библиотеки ВП и по нажатию кнопки "Создать архив" формирует архив zip и загружает в библиотеку. Можете под себя переделать его.
Дрбавить в functions.php
add_action("pre-plupload-upload-ui", "appendZipWrapper2UploadUI");
add_action("wp_ajax_createZIP", "createZipArchive");
add_action("wp_ajax_nopriv_createZIP", "createZipArchive");

foreach($queryResult as $row)

$path2File = $_SERVER["DOCUMENT_ROOT"].wp_make_link_relative($row->guid);
if(file_exists($path2File))
{
$zip->addFile($path2File, basename($path2File));
}
}
$result = $zip->close();
$filetype = wp_check_filetype(basename($path2Archive), null);
$wp_upload_dir = wp_upload_dir();
$attachment = array(

}
В общем, нужно воспользоваться рнр.
