Steven Matz made his MLB debut for the Mets earlier today. I think the kid’s going to be all right.
A couple of weeks ago I made a Joomla component for managing menu-module relationships from a per-menu perspective rather than a per-module one. Since this required research on how Joomla records these relationships I figured it’d be worth sharing this information.
Joomla uses a table
#__modules_menu with two columns,
moduleid. When configuring the Menu Assignment section of a Joomla module there are four options to choose from in the “Module Assignment” dropdown:
- On all pages
- No pages
- Only on the pages selected
- On all pages except those selected
The rules for storing rows in the
#__modules_menu table for each selection are as follows:
- For all pages, store one row with this module id and 0 as the menu id
- For no pages, do not store any row with this module id
- For only selected pages, store one row per menu id with this module id
- For on all pages except selected, store the negative menu id of each selection with this module id
For example, if I had three menu items
3 and a module with an id of
10 and I choose “Only on the pages selected” with menu
1 selected, the table would look like this:
If I choose “All except selected” with menus
3 selected, the table would look like this:
Pretty simple, but considering I could not find this information in any official documentation I’m hoping I can save someone else a trip through the Joomla source code.
