Unable to bypass Unique Field restriction even with permissions

Apparently, onclick is now being stripped from the t() function. Perhaps one of the recent Drupal updates. I put together a quick hack as a temporary workaround. I'm sure the maintainers can come up with a proper patch that is better.

sites/all/modules/unique_field/unique_field.module

-        if (user_access('unique_field_perm_bypass')) {
          $form_id = str_replace('_', '-', $form['#id']);
          $msg .= '<p>' . t('Click !here to bypass this check and resubmit.', array('!here' => "<a href=\"#\" onclick=\"jQuery('form#" . $form_id . " input[name=\'unique_field_override\']').val(1);jQuery('form#" . $form_id . "').submit();return false;\">" . t('here') . '</a>')) . '</p>';
        }

+                if (user_access('unique_field_perm_bypass')) {
          $form_id = str_replace('_', '-', $form['#id']);
          drupal_add_js('jQuery(document).ready(function($){$("#unique").click(function(e){jQuery("form#' . $form_id . ' input[name=\'unique_field_override\']").val(1);jQuery("form#' . $form_id . '").submit();e.preventDefault();});});',array('type'=>'inline','scope'=>'footer','group'=>JS_THEME));
          $msg .= '<p>' . t('Click !here to bypass this check and resubmit.', array('!here' => "<a id=\"unique\" href=\"#\">" . t('here') . '</a>')) . '</p>';
        }

I've had the same issue and this patch resolved the error, thank you!

D7 reached its EOL back in January 2025, and there is no active release for D7 for this module anymore.
Development or support is not planned for D7. All D7-related issues are marked as outdated in a bunch.
