Hello
Thank's for your work on this plugin.
It's very complete and... complex :)
I have a project to make a distance calculator (for CO2 compensation) with some functions :
Field 1 : Start city (dropdown)
Field 2 : End city (dropdown rely on Field 1)
Field 3 : Get distance in database and display (read only)
Field 4 : nbr of passengers on this travel (classic dropdown)
Field 5 : Field 3 * Field 4 (calculated field)
I have made this :
1> I have created database DONNEES with 4 columns (FROM, CITY, KMS, CO2)
2> I have filled a dropdown (Field 1) from database with success (mySQL)
3> I have filled a dropdown (Field 2) with this sql query
SELECT CITY FROM DONNEES WHERE FROM=<%fieldname1%>
Problem > a empty lines appears in dropdown Field2
First Question > How display data in dropdown ?
Second question > How get data in KMS and CO2 columns after selection FROM (Field1) and CITY (Field2)
