I made that correction, but still got the blank browser screen when I tried to duplicate an item. I turned on error reporting, and got this:
Fatal error: Uncaught Error: Undefined constant “item_duplicator_empty_fields_check” in /home/scklsdli/goddard.digitalsckls.info/plugins/ItemDuplicator/ItemDuplicatorPlugin.php:212 Stack trace: #0 /home/scklsdli/goddard.digitalsckls.info/application/libraries/Omeka/Plugin/Broker.php(154): ItemDuplicatorPlugin->hookBeforeSaveItem(Array) #1 /home/scklsdli/goddard.digitalsckls.info/application/libraries/Omeka/Record/AbstractRecord.php(301): Omeka_Plugin_Broker->callHook(‘before_save_ite…’, Array) #2 /home/scklsdli/goddard.digitalsckls.info/application/libraries/Omeka/Record/AbstractRecord.php(529): Omeka_Record_AbstractRecord->runCallbacks(‘beforeSave’, Array) #3 /home/scklsdli/goddard.digitalsckls.info/plugins/ItemDuplicator/controllers/ItemsController.php(101): Omeka_Record_AbstractRecord->save(false) #4 /home/scklsdli/goddard.digitalsckls.info/application/libraries/Zend/Controller/Action.php(516): ItemDuplicator_ItemsController->duplicateAction() #5 /home/scklsdli/goddard.digitalsckls.info/application/libraries/Zend/Controller/Dispatcher/Standard.php(308): Zend_Controller_Action->dispatch(‘duplicateAction’) #6 /home/scklsdli/goddard.digitalsckls.info/application/libraries/Zend/Controller/Front.php(954): Zend_Controller_Dispatcher_Standard->dispatch(Object(Zend_Controller_Request_Http), Object(Zend_Controller_Response_Http)) #7 /home/scklsdli/goddard.digitalsckls.info/application/libraries/Zend/Application/Bootstrap/Bootstrap.php(105): Zend_Controller_Front->dispatch() #8 /home/scklsdli/goddard.digitalsckls.info/application/libraries/Zend/Application.php(384): Zend_Application_Bootstrap_Bootstrap->run() #9 /home/scklsdli/goddard.digitalsckls.info/application/libraries/Omeka/Application.php(73): Zend_Application->run() #10 /home/scklsdli/goddard.digitalsckls.info/admin/index.php(28): Omeka_Application->run() #11 {main} thrown in /home/scklsdli/goddard.digitalsckls.info/plugins/ItemDuplicator/ItemDuplicatorPlugin.php on line 212
So I edited line 212 of that file, changing from
if (get_option(item_duplicator_empty_fields_check)) {
to
if (get_option('item_duplicator_empty_fields_check')) {
by adding the single quotes, and now it seems to be working fine! I will do some more testing later, but it looks good so far. Thank you!
