First of all: I am Austrian and my English is bad for sure. I apologize, but I try.
Second: on behalf of PHP I am a newbie. Do not have probs with databases (normally).
What I am trying to do:
I would like to generate a filter for database sql script (which is no prob for me); this filter is a dynamic dropdown (I THINK, this is no problem for me), which should react on user action. Oh - You guess right - now my problem begins.
In a later version I will make this page available for a choice of database-lists.
I am thankfull for every hint.
I want to get rid of the submit-knob - as I mentioned before.
Thanks for reading, thanks for hopefully helping.
