Hi and welcome!

Relating tables is pretty straight-forward thanks to cook!

Lets say you have 2 tables - families and family_members each with an id (auto created in cook) and a name field + in the family_members table, add a foreign key field type called family. Then, from your tables list on the left-hand side, drag the families table into the dashed div and click the save button. That's it! Simple, eh?

Now all you have to do is create a layout to enter and view data for both tables. When you do this and you drag your fields to the layout, simply click the + sign on the foreign key field (family) and drag one of the related fields from that table to your layout. This is what you'll see in your layout - either in the combo dropdown on your form or in a grid/fly.

Hope it helps,

Gez

You could add multiple family members to a family in this example. Gez Need help with your Cook/Joomla Project? . PM me to find out what I can help with. NO time wasters please!!!

JoomGuy Offline Moderator Joomla Enthusiast, Lover of Cooking Posts: 1115 Thank you received: 195	You need to create a layout for that - 1 where you filter by family and show related members. What you are currently looking at is family members from all families. You'd need separate query - prepareQuery() function in your model to get say family 1 and all of it's members.

there's a few things you can do:

1 - add a filter to the table based on your family
2 - group by family (find this in your grid properties of the layout
3 - as I said before, add a where clause in a new 'case' so you can switch to filter by family.id (after download)

Hope it helps!
