Dynamic Dropdowns inserting ID value instead of text value

Dynamic Dropdowns inserting ID value instead of text value

I almost got this working very quickly. The drop downs themselves work on the page correctly, but I have gotten the fields wrong somewhere. Looking through the tutorial I think I've followed it correctly, but must have gone wrong somewhere.

The tables are:

Parent - categoriesFull

CategoryID (PK)
Category

eg 12, Best Safari Cuisine

Child - categoriesShort

CategoryShortID (PK)
CategoryShort
CategoryFullID

eg 12, cuisine, 12

And I have this as my insert:

$ins_nominations->addColumn("Category", "STRING_TYPE", "POST", "Parent");
$ins_nominations->addColumn("Category_Short", "STRING_TYPE", "POST", "Child");

Which is inserting the 12, 12 instead of Best Safari Cuisine, cuisine.

Have attached a copy of the file.

Thanks.

yes, the select list will pass the ID as the value when inserted, that is the desired behavior. it should insert the ID value, that is the proper use a relational database.

the category name is defined in the category tabel you relate the category to an item by using the category ID in the item table.

the point of a relational database is data normalization. it takes less storage to store an ID in the item table to to store a string. you don't want to repeat the category name over and over again, that would be a waste ofd space.

store the ID in the items table which is more efficiant, and use a join query to return the related information from the items and category table when you need to display it.

I'm with you - up until now I had the categories in my nomination table, but now that I have a new table for categories, I don't need them in there. Just, as you say, the CategoryID.
