NOTE: This extension has been deprecated in favor of CreateBox. Please use that extension for new installations.

This plugin defines an action=create page for use with the Inputbox extension. Action=create allows Inputbox to check whether a page already exists and displays an error message if it does.

Additionally, this code allows Inputbox to define prefixes for the pages it creates. (I.e., submitting "Page" to an inputbox would result in the creation of "Prefix:Page".)

The code listed here should be installed into Inputbox directly, instead of into LocalSettings.php. Here is a step-by-step procedure:

  1. Upload the code listed here into extensions/create.php
  2. Add this line to inputbox.php: include("extensions/create.php");
  3. At the line 227 inputbox.php contains value="edit", replace it with value="create".

Modifying Inputbox to allow for prefixes is somewhat more involved. Here is a modified version with the necessary changes.

The complete code for action=create is listed below.

<?php
/*
 
 This extension defines a new action for use with the InputBox extension.
 After installation, modify the InputBox code so that the creation form has
 action=create instead of action=edit.  Optionally, you may also define
 an extra parameter named "prefix", which will prepend itself to the
 text input upon submission.
