Good day, and thank you in advance for any help.

I am a new MySQL user, and have just recently begun to learn something about
PHP. I usually work with MS Access, and I can build databases, queries,
table and so forth. So I think I understaqnd that stuff well enough to do
most of what I want to do, but my project includes some stuff that I'm not
familiar with.

I am slowly working through the process of putting a small database on line
for an organization that I help to run. The database will list events in
certain geographic areas, and the user/visitor will be able to select the
geographic area in which he or she has an interest. It is not going to be a
huge pile of data.

We (those of us who run the organization) do not want to spend a lot of time
maintaining this data, and there will be a relatively small number of people
who we will want to be able to set up an event. I would like to allow anyone
with a password, or some other way to log in, to be able to put their own
data in, and wait for someone from my organization to approve it. So, my
question is this - what is the best way to keep invalid logins from getting
to the input form? I guess I need to check the log-in data against another
database - or do I? Any tutorials on this subject, or on DB security, in
general, will be appreciated.

Thanks...
