Yeah. Never claimed to be any good at this :( Just persistent :)

Well, I tried Content-Type: text/html and that threw an HTTP 500 Error.

When it doesn´t execute the code, how can it be called successful? If it
doesn´t execute the code, how can you say it´s not an error? What is it,
then?

Very good advice. Please help me understand how to do that.
This is what I have done. I have tried these:
sql = "'insert into products (" + col_names + ") values (" + val + ")', (" +
col_names + ")"
cursor.execute(sql)
and
sql = "'insert into products (" + col_names + ") values (" + val + ")'"
cursor.execute(sql, (col_names,))
Neither work. However, if I print what that code spits out:
sql = "'insert into products (" + col_names + ") values (" + val + ")', (" +
col_names + ")"
print sql
then copy and paste it into a cursor.execute() statement, viola! Everything
works _just_fine_. Go figure. Why??
Incidentally, all that is without using images, and obviously since it
posted to the database after copying and pasting, I believe I am dealing
only with a python problem.
Now, concerning images, this is what I have so far.
I put an image on the server, and did this:
imgfile=open("1.jpg",'rb')
f = imgfile.read()
pic1 = _mysql.escape_string(f)
It does not like this (forgot error):
pic1 = MySQLdb.Binary(f)
Escaping the string, I can successfully load this image into the database,
along with all the other fields. Now, when I load an image from the form on
the previous page with this code:
<input type='file' name='pic1' value="""
print '"', MySQLdb.Binary(data[14]), '"'
and send the form off to the next page, when I process it on that page with
this code:
pic1 = _mysql.escape_string(pic1)
print pic1
it prints out a messy binary that (almost) starts with something like ¨This
program can only be run in Win32¨, whatever that means. But a binary is
printed. (It may be an infinite binary, I stopped it after a few minutes.)
Now, if I stick it into the cursor.execute like I did above, it throws an
HTTP non-error non-posting-to-the-database 200 error. I´m more than happy to
separate all this garbage out for further testing, but I don´t know how to
do that. Your help is very much appreciated.
