Module to choose whether external links open in new window?

What you need is not a module, but rather a filter. A filter manipulates the text of a node before it is output to the browser.

There are several examples in the modules Download section, look at image filter, code filter, ...etc.

On maybe WordPress (?) I've seen a visitor-optional checkbox to set whether you want the links to open into a new window or not. I'm not sure, but I would think it'd have to targe only off-site links or navigating the site would be a nightmare. Also, it seemed to be a persistent setting, but always available for change.

Something like this, which would have a block where the user could set this, might be nice. +1 from me.

Paste this in a file called newwindow.module and install it as a module:

function newwindow_filter($op, $delta = 0, $format = -1, $text = '') {
  switch ($op) {
    case 'list':
      return array(0 => t('New window filter'));

    case 'description':
      return t('Forces external links in submitted content to open in a new window.');

    case "process":
      return preg_replace('!<a (?:href=["\']?http)!i', '<a target="_blank" ', $text);

    default:
      return $text;
  }
}

This code assumes there are no existing target="" attributes. You can put this is in the default input format to force it for everyone. As an administrator you could still use Full HTML if you don't want the links to open externally. You can even provide your users with a choice by setting up a new input format like Filtered HTML, and giving them access to both the format with the NewWindow filter and the one without the filter.

One option would be to put the following on the page:

_{Press [Shift] to open links in a new window.}

of course you could add:

<?php if(stristr($_SERVER["HTTP_USER_AGENT"],"firefox" != FALSE ) { ?>or [Ctrl] to open in a new tab.<?php } ?>

Another simple option is to add the following line:

<base target="link" >

to your template, which will make all links on the page open in a seperate window (reusing the same window). You will need to manually add "target='_self'" to all links you want to open in the current window.

To cause the default action for each link to be a new window, use
<base target="_new" >
instead.

I've found this page which is a JS script to do new links in a new window... works great for me:

http://muzso.hu/node/59

When people open a new link from my site, I want to keep my site open in the background. What a pig, eh? So, in the includes directory, about line 1090 in common.inc, I replaced

return '<a href="'. check_url(url($path, $query, $fragment, $absolute)) .'"'. drupal_attributes($attributes) .'>'. ($html ? $text : check_plain($text)) .'</a>';

with

if(substr($path,0,4)=="http"){
  return '<a href="'. check_url(url($path, $query, $fragment, $absolute)) .'"'. drupal_attributes($attributes) . 'target=\"_blank\">'. ($html ? $text : check_plain($text)) .'</a>';
}
else{
  return '<a href="'. check_url(url($path, $query, $fragment, $absolute)) .'"'. drupal_attributes($attributes) .'>'. ($html ? $text : check_plain($text)) .'</a>';
}

When "http" are the first four characters in the menu item URI, the link is automatically external.

No problems so far. (5 minutes!!)

Just wanted to post and say thanks to princeofwales aka Chris Brown (August 5, 2006 - 23:05) - for your code solution in common.inc.

I'm pretty new to PHP but I must say it's impressed me, and the contribution of people like yourselves is just amazing in using applications like Drupal.

Thanks again!

For anyone wanting this for Drupal 6, the External New Tab module (http://drupal.org/project/external) does it.
