I have a numeric value that is unique to each domain (using Domain Access) on my site. I'd like to use the same variable name so I can use the same theme and display this value on all domains. Is this possible?

I'm currently defining the variable in a custom module, but I'm only storing 1 value. Can I alter the code in the custom module so that each domain can have it's own unique value for this variable?

UPDATE:

Adding the following when defining the variable in my custom module worked :D

'multidomain' => true,

I can edit the variable through admin/config/system/variable/edit/ and I get unique values across my domains stored in the variable_store table. The problem I now have is that I want to create an admin form for getting/setting a bunch of domain variables and the usual variable_get/variable_set don't work...any thoughts?

You must enable "domain configuration" submodule (domain_conf) This will provide you the save per domain option:

function your_module_form($form, &$form_state) { $form['variable'] = array( '#type' => 'value', '#value' => time(), ); return system_settings_form($form); }

getting the variable manually:

function domain_conf_variable_get($domain_id, $variable = '', $all = FALSE, $reset = FALSE)

seeting the variable manually:

function domain_conf_variable_set($domain_id, $variable, $value = NULL)

There is a module which aims to be a replacement variable handling module for Domain Access,If you need setting different variable values for each domain and for each language at the same time you need domain variable module https://drupal.org/project/domain_variable

Another way to do it is with

hook_domain_batch

which gives you a nice settings UI under Domain > Settings

For example, I wrote an implementation of that hook for per-domain apachesolr site hash settings:

/** * Implements hook_domain_batch(). * * Add batch settings to Domain Conf. */ function MODULENAME_domain_batch() { $batch = array(); if(function_exists('apachesolr_site_hash')){ $batch['apachesolr_site_hash'] = array( '#form' => array( '#title' => t('Apache Solr site hash'), '#type' => 'textfield', '#description' => t('Unique site hash for Apache Solr.'), ), '#domain_action' => 'domain_conf', '#permission' => 'administer site configuration', '#system_default' => apachesolr_site_hash(), '#meta_description' => t('Set Apache Solr site hash for each domain.'), '#variable' => 'apachesolr_site_hash', '#data_type' => 'string', '#weight' => -1, '#group' => t('Apache Solr'), '#update_all' => TRUE, '#module' => t('Apache Solr'), ); } return $batch; }

Then you can just use variable_get to retrieve the value on that domain.

  • Can you just use variable_get(), or do you need to use domain_conf_variable_get() as mentioned in Enxebre's answer? Commented Feb 17, 2014 at 20:13
  • You can use variable_get for the current domain value. If you want the value for a different domain, use domain_conf_variable_get Commented Feb 17, 2014 at 22:33

Ok, here is how I solved it...I hope this is the "right" way:

Define the variable, 'multidomain' being the import difference

function MODULENAME_variable_info($options) { $variable['social_media_link_twitter'] = array( 'title' => t('Twitter', array(), $options), 'description' => t('Twitter URL', array(), $options), 'type' => 'string', 'multidomain' => true, 'access' => 'social media links' );

Create a menu to get to the admin form

function MODULENAME_menu() { $items = array(); $items['admin/social-media-links'] = array( 'title' => t('Social Media Links'), 'page callback' => 'MODULENAME_social_media_links_admin', 'access arguments' => array('social media links'), ); return $items; }

Menu Page Callback

function MODULENAME_social_media_links_admin() { return drupal_get_form('MODULENAME_socialmedialinks_form'); }

Form Declaration

function MODULENAME_socialmedialinks_form($form_state) { /* Just regular old variable_get() */ $form['social_media_link_twitter'] = array( '#title' => t('Twitter'), '#type' => 'textfield', '#description' => t('Enter your twitter URL. Example: http://twitter.com/SomethingOn'), '#default_value' => variable_get('social_media_link_twitter', '') ); /* return the system settings form, not just $form */ return system_settings_form($form); }

Form Submit

function MODULENAME_socialmedialinks_form_submit($form, &$form_state) { /* For some reason I have to manually get the domain and set the realm?! */ $domain = domain_get_domain(); variable_realm_switch('domain', $domain['subdomain']); domain_conf_variable_set($domain['domain_id'], 'social_media_link_twitter', $form_state['values']['social_media_link_twitter']); }
