I have a menu with top and sub items. All the items, top and sub items have a unique "id" in the database and a "parentid". Top items, all have "parentid" "0" as value, sub items have "parentid" same as the "id" of the top item they correspond to..
Is there a way to select the menu from the db to look like this on the page?
Top Item 1 - My Own Sub Item 1, My Own Sub Item 2, My Own Sub Item 3
Top Item 2 - My Own Sub Item 1, My Own Sub Item 2, My Own Sub Item 3
Top Item 3 - My Own Sub Item 1, My Own Sub Item 2, My Own Sub Item 3
etc.
I am new to databases, I tried everything but I can't get what I want.. Thank you for any help!
You need to have a parent child relation between the top menu and the sub items, so you need to create an extra column in the sub items table, say, main_menu_id, after doing this, you need to assign id of the main menu to the sub menu item in that column.
Later you will need a nested while loop using PHP and have to fetch the records accordingly.
/* Loop Top Items Starts
Loop Inner Items (Fetch Sub Items Having ID Of The Main Item)
Loop Top Items Ends
*/
1st Query
SELECT * FROM main_menu;
2nd Query (Nested In While Loop)
SELECT * FROM sub_menu WHERE main_menu_id = $looped_id;
