Confiforms detect empty database response

[Javier L]

Hi there dear experts,

I have a Dynamic Dropdown database with 'Use as proxy' set. It works really fine but I would like to detect if there was no outcoming data from the query, and do something like showing another field or chaging the style of a field

Thanks

You mean that you want to catch the event when nothing can be selected from the offered choices?

How this should work in your mind? 

Setting the ConfiForms Field Definition Rules to track the field is empty (and having an "action" performed) is not good?

There is a difference between 'there is nothing in the database' and 'the user has not put anything in the search yet' . Both cases the seach inbox is empty but they have complete differente meaning.

Thanks in advance

Still unsure where exactly do you expect these messages to be... Could you clarify?

When the user writes in the dropdown, is there a way to know in a variable such as [entry.anything]  what wrote the user?

For better understanding,

1. The user writes on the dropdown
2. The dropdown returns nothing. Now there is no way to differentiate between input and output.
3. Nevertheless, If exists, i can check on [entry.anything] what the user set in the dropbox.
