need help pulling results using 2 tables.

[a51hh]

table1
ID Category SubCategory
1 100 100010
2 100 100010
3 100 100010
4 100 100020
5 100 100020
6 100 100020
7 100 100020
8 100 100030
9 100 100040

table2
ID Email First Last Address info
1 some@email.com John Smith infohere
2 another@email.com Luis Smith infohere
url.com/searchresults.php?category=100&subcategory=100010

I need to be able to pull and display according to categories and subcategories using $_GET as displayed above.

1st query runs and pulls all of the ID's according to Category and SubCategory.
The resulting IDs need to be displayed in rows using HTML formating and possibly have code to run over multiple pages.

I need to display the results from table 2 after I filter what categories from the $_GET method.

If someone can give me some code examples I would be greatful.

you want to run a query something like this:

SELECT * FROM table1 INNER JOIN table2 ON table1.ID=table2.ID ORDER BY Category, SubCategory;

That will get you a flat table with one row for each person, ordered by category and subcategory.  Then walk through that table, saving the current category or subcategory.  If it is different from the last, print the heading.

That's about right.. you'll need a "seen" hash to keep track.

Thanks guys for the reply. It works like a charm. Glad I have something to fall back on.
