I'm a NEWBIE and I have been stuck on this for days.
I have one table that has the following rows:
rid = Referral ID
category = Category
subcategory = Subcategory
rbusiness = Referred Business Name
rcontact = Referred Contact Name
etc..
I have created the form (referral_input.php) that allows the user to input their referral data including category and subcategory. I have also created a page (my_categories.php) which lists all the categories in which the user has a referral using a WHILE LOOP. From there, I wish for the user to select one of their categories and then be taken to (my_subcategories.php) where I employ another WHILE LOOP. From there, the user would select a subcategory and be taken to a resulting page displaying all the date for that referral (like a contact page in address book).
So here is where I am stuck. I have tried many variations (from $_POST to $GET to SESSION) to pass along the value of their selection on the (my_categories.php) to the (my_subcategories.php) page and include it in the query. None have worked. Any advice and patience is welcome. Also, as I am new, please be descriptive. I see many responses that are one sentence long and mean nothing to those of us starting out.
Here are the pages:
1st page (my_categories.php)
