<?php

/*

Plugin Name: Open Links in New Window

*/



function bb_target_blank( $text ) {

$text = preg_replace('|<a (.+?)>|i', '<a $1 target="_blank">', $text);

return $text;

}

add_filter('post_text', 'bb_target_blank',255);



?>

Put the above into a file and save it as new-window-links.php or similar in your my-plugins directory. Then enable it in the plugins menu. Should work. Avoid getting any spaces around the start and end tags.
