Hi, i have a similar problem that I could not solve and would appreciate some help.
In my case I need to filter a consumer electronic device list to get a model_id so that I can show infra-red commands for that device. So I have 2 tables
1 - device model list with:
1.1 - id (primary key element)
1.2 - device_type (dropdown element) ex DVD, Receiver, TV etc
1.3 - manufacturer (dropdown element) ex Philips, Sony, LG, Samsung, etc
1.4 - model (text field element) ex descripton of the device model.
2 - ir_command list with:
2.1 - id (primary key)
2.2 - model_id (database join element) - linked to device model list
2.3 - button_tag (database join element) - linked to button tag list
2.4 - ir_command (text field)
There are several IR commands for each device model, ON device_model.id = ir_command.model_id
Now I need to create a list with commands for a selected device.
To select a device, the user would like to select a device_type, then select the manufacturer from a filtered list and then select the model from a filtered list.
I tried several approaches, but none of them resulted in something that worked
a) creating a new list with table join with device model list left join with ir command list.
I configured the device_type, manufacturer and model to be filter elements, using dropdown option, but couldn?t find a way to make the resulted dropdonw list be filtered by option of another element. As a result, the filter dropdown shows options that are not in the table records, since all models are listed regardless of the manufacturer chosen.
Since I created this new list using the original database tables, the elements were linked to the original elements, and I have no clue what would hapend If I selected to break that link to change the element type do join elements for example.
b) creating a new list for filtering purpose, to use a submit form to redirect to the ir command list with use elements as filter option on.
I?m halfway on it, but facing another issue that is
device_type is a database join element
manufacturer is a cascading dropdown element that is filtered by device_type.
model element is a cascading dropdown element that is filtered on manufacturer. But then I get models for the same manufacturer that belongs to different device_types. For example Philips have several TV models and several DVD models. All of them get listed in the model element filter dropdown when I select device_type = tv and manufacturer = philips.
I also tried to use the advanced where query " device_type = 'tv' " but that's a static thing.
Is there a way to use a element value stored in session when submited in another form to filter a join element or cdd element in a form called with the redirect plugin ?
Any other ideas ?
What about a CDD2 Element that whates 2 other elements ?
Hope to get some hint on this,
