Multiple search but not all options chosen
I am using CS4 to produce a database using mySQL and php.
I have a table which records a number of variables, each variable being listed in a separate tabel and selected from dropdowns. (For example, London Boroughs, age bands, type of work - the field names are boro, age, work respectively)
I have built a search page which allows a user to select from each of the 3 drop downs and get a list of data which meets the combination selected. BUT if I don't make a choice from one of the lists then I don't get any results.
How can I make it so that I don't have to make a selection from all of the dropdowns?
Thanks for any help.
