Database Query & Dynamic Table Question

Question

Greetings all. I am using Dreamweaver CS3 and working in PHP
with a MySql database. I'm sure the recordset I'm trying to create
is rather simple, but for the life of me I can't figure it out. I
have a table with peoples' names and their grades in different
subjects. For example:
Name Subject 1 Subject 2 Subject 3
John D. 85 72 73
Jane D. 90 85 70
John S. 70 92 85
What I'm wanting is a page with a dynamic table for the
person that logs on to see their grades in each subject if it's
above an 80. I already know how to pass the username session
variable, but I'm not sure how to say "show subject if value is
greater than or equal to 80." So, for example, if John D. logged in
the table would look like:
Subject 1 80
If Jane D logged in, her displayed dynamic table would look
like:
Subject 1 90
Subject 2 85
So, I want the table to show the header name (subject) and
the grade if the grade >= 80. Any ideas on how to solve my
dilemma would be greatly appreciated. Thank you in advance.

Answer 1

Thank you for the reply. I was thinking about doing the
separate table idea, but there are something like 50 subjects, and
I already have the rest of the site built around my current table
structure. I think it would be more trouble than it's worth to
change everything. I'm rather new to PHP, so if you don't mind
helping out, how would I setup the code to say "ok, here's a query
with every subject and name, now pull only the subjects with a
score >= 80 for person A (generated by a URL variable)?" What
I'm envisioning is a repeating table with Subject (if >=80) on
the left, and the actual score on the right. The query I'm using to
pull the scores for the logged in person is
SELECT Name, Subject 1, Subject 2...
FROM Grades
WHERE Name = colname
colname = $_GET['Name'] (my url variable)
This works just fine to pull ll grades for all subjects for
just the person who logged in. I'm not sure how passed this point
to a) filter the subjects by a value, and b) list those subjects
and grades in a vertical repeating table. Thank you again for your
help.
