Domain Access Options

Well, you have two default options here.

Using SEO rewriting by itself, the following rules are enforced:

- If SEO settings are turned on, all node links are rewritten as absolute URLs.
- If assigned to 'all affiliates' the node link goes to the root domain.
- If assigned to a single affiliate, the node link goes to that affiliate.
- If assigned to multiple affiliates, the node link goes to the first matching domain.
(Determined by the order in which domains were created, with your primary
domain matched first.)

You can also use the provided Domain Source module to select which domain a node should be directed to.

Doing this per node (or per node type) would require extra code overhead -- it is possible, however, to alter the custom_url_rewrite_outbound() function to meet your needs.

Since that function is included by settings.php, it would be easy for you to copy the function and edit it as you see fit.

The quick way to do this is to include a switch case early in the function -- this would be the most efficient, but more work for you:

    // Check to see that this function is installed.
    $skip = FALSE;
    $arg = arg(0);
    if ($arg == 'admin' && ($path == 'domain_access_test_path' || $path == 'domain_access_path_test')) {
      $path = 'yes';
      $skip = TRUE;
    }
 
    switch($original_path) {
      case 'node/22':
        $skip = TRUE;
        break;
    }

You could also comment out the final clause in the function, which is the part that affects nodes viewable on all domains:

        // If strict SEO rules are enabled, we set "all affiliate" links to the root domain.
        // Only needed if we are not on the root domain.
 /*       else if ($seo && $_domain['domain_id'] != $root['domain_id']) {
          $options['absolute'] = TRUE;
          // In this case, the $base_url cannot have a trailing slash
          $options['base_url'] = rtrim($root['path'], '/');
        } */

We could add a behavior toggle for how to handle nodes viewable on all domains, which would add yet another configuration option. Probably the best way would be to let you select which domain to use to 'all affiliates' under SEO.

Here's a patch, ready for testing.

It creates another Advanced configuration option:

Default source domain:
When rewriting urls, nodes assigned to all affiliates will be sent to this domain.

This is a select list. Default is root domain.

Revised patch that lets you specify "do not change domain.'

This is still a global setting. It affects all node assigned to 'all affiliates'.

'Do not change domain' should be the first option in the select list.

Under 'default source domain' there should be a select list.

You must apply the patch in #3 correctly and have domains configured.

See attached proof.

There are no conditionals in the patched code.

After applying the patch, lines 277-290 of domain.admin.inc should be:

  $options = array('-1' => t('Do not change domain'));
  foreach (domain_domains() as $data) {
    // The domain must be valid.
    if ($data['valid']) {
      $options[$data['domain_id']] = $data['sitename'];
    }
  }
  $form['domain_advanced']['domain_default_source'] = array(
    '#type' => 'select',
    '#title' => t('Default source domain'),
    '#options' => $options,
    '#default_value' => variable_get('domain_default_source', 0),
    '#description' => t('When rewriting urls, nodes assigned to all affiliates will be sent to this domain.'),
  );

This has been committed to HEAD for testing.

Needs documentation and a port to D5.

Committed to HEAD and 5.x.
