Deleting a Domain

Better to script it in a hook_update_N() so you can call hook_domainupdate().

function custom_update_6000() {
  $ret =  array();
  $domains = array(3, 5, 6); // domains to delete, by ID.
  foreach ($domains as $domain_id) {
    $domain = domain_load($domain_id);
    if ($domain == -1) {
      continue;
    } 
    db_query("DELETE FROM {domain} WHERE domain_id = %d", $domain['domain_id']);
    // Populate dummy form.
    $form_state = array('values' => array('domain' => $domain));
    // Run the update across all modules.
    module_invoke_all('domainupdate', 'delete', $domain, $form_state);
  }
  // Flag node access for rebuild.
  node_access_needs_rebuild();
  return $ret;
}

This is actually exactly what I'm doing now also. Say you were to go about this "physically"... without the hook update? I honestly have no clue how to run a hook update...

Okay - well I did some research to give the hook update a shot... may as well learn, right!

I placed this exact code in the "domain.install" file...

function custom_update_6000() {
  $ret =  array();
  $domains = array(0); // domains to delete, by ID.
  foreach ($domains as $domain_id) {
    $domain = domain_load($domain_id);
    if ($domain == -1) {
      continue;
    }
    db_query("DELETE FROM {domain} WHERE domain_id = %d", $domain['domain_id']);
    // Populate dummy form.
    $form_state = array('values' => array('domain' => $domain));
    // Run the update across all modules.
    module_invoke_all('domainupdate', 'delete', $domain, $form_state);
  }
  // Flag node access for rebuild.
  node_access_needs_rebuild();
  return $ret;
}

I'm trying to erase the original Domain... so Domain id (0). After running update, I am seeing no changes at all.
Obviously I am missing something here. I've copied all the tables & folders... and this is in the new website's database which I am splitting off. Is it possible to delete that original domain id (0) this way?

Your hook_update_N must be named for the module it belongs to. custom_update_6000() will only run from custom.install.

You also can't erase domain 0. It's required. The module will break without it.

okay. well i guess there has to be another way then? i am splitting id#2 onto its own... and im done with everything except getting id#0 erased.

Thanks for you help!

Well, normally, you would copy the db, delete all content and users not assigned to 'all affiliates' or domain 2 (if you want to do so), and then just uninstall the DA suite.
