	$attachment_ids = (array) $attachment_ids;
	$wp_upload_dir = wp_upload_dir();
	$attachments = array();

	// THIS WILL NOT WORK > WPv3.8.1
	foreach( $attachment_ids as $attachment_id ){
	$attachment = wp_get_attachment_metadata( $attachment_id );
	if( !empty( $attachment['file'] ) ){
	$attachments[] = trailingslashit( $wp_upload_dir['basedir'] ) . $attachment['file'];

codearachnid / jquery-highlightWord.js

Created November 22, 2013 22:02

Currently tested this will scan a reasonable page within 1000 …
