View source for Zen Cart admin menu

In [[Zen Cart]], the admin menu is a set of features for administrators.

== Adding items to the menu ==

Version: v1.5.x.
Let's say that you have a new tool named new_tool.php that you want to plug into the Tools menu.

Most of the files that you distribute in the new_tool.zip file are identical with previous Zen Cart versions:

<pre>

/YOUR_ADMIN/new_tool.php
Contains the code that implements your new tool.

/YOUR_ADMIN/includes/extra_datafiles/new_tool_filenames.php
Contains the filename definition for your new tool, e.g. define('FILENAME_NEW_TOOL', 'new_tool');

/YOUR_ADMIN/includes/languages/english/extra_definitions/new_tool_name.php
Contains the menu entry text definition for your new tool, e.g. define('BOX_TOOLS_NEW_TOOL', 'New Tool');

/YOUR_ADMIN/includes/languages/english/new_tool.php
Contains the language-specific defines for your new tool; the filename of the language file must be the same as the filename of the tool itself.

The file that you distribute to actually add new_tool.php to the Tools menu is different for v1.5.0 and later. In previous versions of Zen Cart, you would have distributed a file named:

/YOUR_ADMIN/includes/boxes/extra_boxes/newtool_tools_dhtml.php that contained
Code:
$za_contents[] = array('text' => BOX_TOOLS_NEW_TOOL, 'link' => zen_href_link(FILENAME_NEW_TOOL, '', 'SSL'));
For Zen Cart v1.5.0 and later, you will include a file similar to the following:

/YOUR_ADMIN/includes/functions/extra_functions/init_new_tool.php:
Code:
if (!defined('IS_ADMIN_FLAG')) {
    die('Illegal Access');
} 

//----
// If the installation supports admin-page registration (i.e. v1.5.0 and later), then
// register the New Tools tool into the admin menu structure.
//
// NOTES:  
// 1) Once this file has run once and you see the Tools->New Tool link in the admin
// menu structure, it is safe to delete this file (unless you have other functions that
// are initialized in the file).
// 2) If you have multiple items to add to the admin-level menus, then you should register each
// of the pages here, just make sure that the "page key" is unique or a debug-log will be
// generated!
//
if (function_exists('zen_register_admin_page')) {
  if (!zen_page_key_exists('toolsNewTool')) {
    zen_register_admin_page('toolsNewTool', 'BOX_TOOLS_NEW_TOOL', 'FILENAME_NEW_TOOL','' , 'tools', 'Y', 20);
  }    
}
The value toolsNewTool is a (hopefully) unique value that identifies your new tool.
The values BOX_TOOLS_NEW_TOOL and FILENAME_NEW_TOOL are defined within the other files within your toolset.
The fourth parameter ('') has any parameters that your tool might require. (Rarely used.)
The fifth parameter ('tools' in the example) identifies which of the high-level menu items your tool "attaches" to, one of: configuration, catalog, modules, customers, taxes, localization, reports, tools, gv, access, or extras.
The sixth parameter ('Y') identifies whether ('Y') or not ('N') to display the page on the admin menu.
The seventh parameter (20) is the sort order for the page, i.e. where it lives on the drop-down menu in relation to the sort order of others.


To remove your menu item, in the case a store-owner chooses to un-install your plugin, simply include a file in your distribution zip-file named /uninstall_new_page.sql that contains
Code:
DELETE FROM admin_pages WHERE page_key='toolsNewTool';
Notes:
Instead of distributing the init_new_tool.php file, you could include instructions to install using the Admin Access Management->Admin Page Registration tool.
Set Page Key to toolsNewTool
Set Page Name to BOX_TOOLS_NEW_TOOL
Set Page File Name to FILENAME_NEW_TOOL
Leave Page Parameters blank
Select "Tools" from the Menu dropdown
Check the "Show on Menu" box
Set the Sort Order to 20
If you don't see your newly added item, it's likely somewhere in the middle of the menu's dropdown list.
Use 999 (or any other large number) for the sort order value if you want to ensure that your item is at the bottom of the menu's list.
To reposition an item within one of the admin menus, use phpMyAdmin and browse the admin_pages table to find the added menu item and adjust its sort_order value as desired.
