Hi! I'm sorry if this question is pretty basic. I have a form, which data are used to make a database query. As there always has to be at least one search criteria in the query, one form field (it doesn't matter which one) always has to be filled. In other words I will have to check the form for being empty. I just don't know how I would accomplish this in a good way. I would appreciate if anyone could help me or give me a hint.
