• Programmatically adding a menu item to the v1.5.0 (and later) admin

    Every time I'm adding a new item to my v1.5.x admin, I search the forums and can never find the post (I know it's there) that identifies how to get your new tool added to the admin menu ... so I'm noting the process here.

    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:

    /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: [View]
    $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: [View]
    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: [View]
    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.
      1. Set Page Key to toolsNewTool
      2. Set Page Name to BOX_TOOLS_NEW_TOOL
      3. Set Page File Name to FILENAME_NEW_TOOL
      4. Leave Page Parameters blank
      5. Select "Tools" from the Menu dropdown
      6. Check the "Show on Menu" box
      7. 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.
