Question2Answer Merge Plugin

This plugin adds advanced question and blog post management features to Question2Answer (Q2A).
Admins can Copy, Merge, or Only Redirect questions and blog posts — including across networked Q2A sites.

Important: This plugin requires a minor modification in Q2A core to allow overriding of the qa_page_q_close_q_submit() function. (Instructions below)

---

Installation

1. Copy this plugin folder into your Q2A /qa-plugin/ directory.
2. Modify the core file qa-include/pages/question-post.php:
   • Locate the function:

     function qa_page_q_close_q_submit($question, $closepost, &$in, &$errors)

   • Add this line as the first line inside the function:

     if (qa_to_override(__FUNCTION__)) { 
         $args = func_get_args(); 
         return qa_call_override(__FUNCTION__, $args); 
     }

3. In the Q2A Admin Panel → Plugins, enable Q2A Merge.

Note

• Copy/Merge/Only Redirect dialog appears automatically when:
  • A question is marked as duplicate, OR
  • The "closed note" contains a network site URL.
